Growth inhibition of foodborne pathogens and food spoilage organisms by select raw honeys.

Twenty-seven honey samples from different floral sources and geographical locations were evaluated for their ability to inhibit the growth of seven food spoilage organisms (Alcaligenes faecalis, Aspergillus niger, Bacillus stearothermophilus, Geotrichum candidum, Lactobacillus acidophilus, Penicillium expansum, Pseudomonas fluorescens) and five foodborne pathogens (Bacillus cereus, Escherichia coli O157:H7, Listeria monocytogenes, Salmonella enterica Ser. Typhimurium, and Staphylococcus aureus) using an overlay inhibition assay. They were also tested for specific activity against S. aureus 9144 and B. stearothermophilus using the equivalent percent phenol test--a well diffusion assay corresponding to a dilute phenol standard curve. Honey inhibited bacterial growth due to high sugar concentration (reduced water activity), hydrogen peroxide generation, and proteinaceous compounds present in the honey. Some antibacterial activity was due to other unidentified components. The ability of honey to inhibit the growth of microorganisms varies widely, and could not be attributed to a specific floral source or demographic region produced in this study. Antibacterially active samples in this study included Montana buckwheat, tarweed, manuka, melaleuca, and saw palmetto. Furthermore, the bacteria were not uniformly affected by honey. Varying sensitivities to the antimicrobial properties were observed with four strains of S. aureus thus emphasizing the variability in the antibacterial effect of honey samples. Mold growth was not inhibited by any of the honeys tested. B. stearothermophilus, a heat-resistant spoilage bacteria, was shown to be highly sensitive to honey in both the overlay and well diffusion assays; other sensitive bacteria included A. faecalis and L. acidophilus. Non-peroxide antibacterial activity was observed in both assays; the highest instance was observed in the specific activity assay against B. stearothermophilus. Further research could indicate whether honey has potential as a preservative in minimally processed foods.

Inhibitory activity of honey against foodborne pathogens as influenced by the presence of hydrogen peroxide and level of antioxidant power.

Antimicrobial activity of honey has been attributed to hydrogen peroxide, which is produced by naturally occurring glucose oxidase, and phenolic compounds, although lethality of and inhibition by these and other components against microorganisms vary greatly, depending on the floral source of nectar. This study was undertaken to compare honeys from six floral sources for their inhibitory activity against Escherichia coli O157:H7, Salmonella typhimurium, Shigella sonnei, Listeria monocytogenes, Staphylococcus aureus, and Bacillus cereus. A disc assay revealed that development of zones of inhibition of growth depends on the type and concentration of honey, as well as the test pathogen. Growth of B. cereus was least affected. The inhibition of growth of S. sonnei, L. monocytogenes, and S. aureus in 25% solutions of honeys was reduced by treating solutions with catalase, indicating that hydrogen peroxide contributes to antimicrobial activity. Darker colored honeys were generally more inhibitory than light colored honeys. Darker honeys also contained higher antioxidant power. Since antimicrobial activity of the darker colored test honeys was not eliminated by catalase treatment, non-peroxide components such as antioxidants may contribute to controlling the growth of some foodborne pathogens. The antibacterial properties of honeys containing hydrogen peroxide and characterized by a range of antioxidant power need to be validated using model food systems.

Topical application of natural honey, beeswax and olive oil mixture for atopic dermatitis or psoriasis: partially controlled, single-blinded study.

OBJECTIVES: To investigate the effects of honey, olive oil and beeswax mixture on patients with atopic dermatitis (AD) or psoriasis vulgaris (PV). MATERIALS AND METHODS: Twenty-one patients with dermatitis and 18 patients with psoriasis were entered for patient-blinded, partially controlled study; 11 patients with dermatitis used topical betamethasone esters and 10 patients with psoriasis used clobetasol propionate. Honey mixture contained honey, beeswax and olive oil (1:1:1). Mixtures A, B, and C contained honey mixture with the corticosteroids ointment in a ratio of 1:1, 2:1, and 3:1 respectively. Patients with dermatitis were subjected to controlled bilateral half-body comparison to evaluate the efficacy of honey mixture against Vaseline, or mixture A against Vaseline-betamethasone esters mixture (1:1) in patients using topical corticosteroid treatment. In patients with psoriasis, the effect of honey mixture was compared with paraffin in an individual right/left-sites comparison, or mixture A against paraffin-clobetasol propionate mixture (1:1) in patients using corticosteroid topical therapy. In dermatitis, body lesions on right or left half-body were assessed for erythema, scaling, lichenification, excoriation, indurations, oozing and itching on a 0-4 points scale. In psoriasis, lesions of selected site were assessed for redness, scaling, thickening and itching, on a 0-4 points scale. RESULTS: In honey mixture group, 8/10 patients with dermatitis showed significant improvement after 2 weeks, and 5/11 patients pretreated with betamethasone esters showed no deterioration upon 75% reduction of corticosteroid doses with use of mixture C. In psoriasis, 5/8 patients showed a significant response to honey mixture. In patients using clobetasol propionate, 5/10 patients showed no deterioration upon 75% reduction of corticosteroid doses with use of mixture C. CONCLUSION: Honey mixture appears useful in the management of dermatitis and psoriasis vulgaris.

Flavonoids in monospecific eucalyptus honeys from Australia.

The HPLC analyses of Australian unifloral Eucalyptus honeys have shown that the flavonoids myricetin (3,5,7,3',4', 5'-hexahydroxyflavone), tricetin (5,7,3',4',5'-pentahydroxyflavone), quercetin (3,5,7,3',4'-pentahydroxyflavone), luteolin (5,7,3', 4'-tetrahydroxyflavone), and kaempferol (3,5,7, 4'-tetrahydroxyflavone) are present in all samples. These compounds were previously suggested as floral markers of European Eucalyptus honeys. The present results confirm the use of flavonoid analysis as an objective method for the botanical origin determination of eucalyptus honey. Honeys from E. camaldulensis (river red gum honey) contain tricetin as the main flavonoid marker, whereas in honeys from E. pilligaensis (mallee honey), luteolin is the main flavonoid marker, suggesting that species-specific differences can be detected with this analysis. The main difference between the flavonoid profiles of Australian and European Eucalyptus honeys is that in the Australian honeys, the propolis-derived flavonoids (pinobanksin (3,5, 7-trihydroxyflavanone), pinocembrin (5,7-dihydroxyflavanone), and chrysin (5,7-dihydroxyflavone)) are seldom found and in much smaller amounts.

Identification and quantification of antioxidant components of honeys from various floral sources.

Little is known about the individual components of honey that are responsible for its antioxidant activity. The present study was carried out to characterize the phenolics and other antioxidants present in honeys from seven floral sources. Chromatograms of the phenolic nonpolar fraction of the honeys indicated that most honeys have similar but quantitatively different phenolic profiles. Many of the flavonoids and phenolic acids identified have been previously described as potent antioxidants. A linear correlation between phenolic content and ORAC activity was demonstrated (R(2) = 0.963, p < 0.0001). Honeys were separated by solid-phase extraction into four fractions for sugar removal and separation based on solubility to identify the relative contribution of each fraction to the antioxidant activity of honey. Antioxidant analysis of the different honey fractions suggested that the water-soluble fraction contained most of the antioxidant components. Specific water-soluble antioxidant components were quantified, including protein; gluconic acid; ascorbic acid; hydroxymethylfuraldehyde; and the combined activities of the enzymes glucose oxidase, catalase and peroxidase. Of these components, a significant correlation could be established only between protein content and ORAC activity (R(2) = 0.674, p = 0.024). In general, the antioxidant capacity of honey appeared to be a result of the combined activity of a wide range of compounds including phenolics, peptides, organic acids, enzymes, Maillard reaction products, and possibly other minor components. The phenolic compounds contributed significantly to the antioxidant capacity of honey but were not solely responsible for it.

Floral classification of honey using mid-infrared spectroscopy and surface acoustic wave based z-Nose Sensor.

Fourier transform infrared spectroscopy (FTIR) and z-Nose were used as screening tools for the identification and classification of honey from different floral sources. Honey samples were scanned using microattenuated total reflectance spectroscopy in the region of 600-4000 cm(-1). Spectral data were analyzed by principal component analysis, canonical variate analysis, and artificial neural network for classification of the different honey samples from a range of floral sources. Classification accuracy near 100% was achieved for clover (South Dakota), buckwheat (Missouri), basswood (New York), wildflower (Pennsylvania), orange blossom (California), carrot (Louisiana), and alfalfa (California) honey. The same honey samples were also analyzed using a surface acoustic wave based z-Nose technology via a chromatogram and a spectral approach, corrected for time shift and baseline shifts. On the basis of the volatile components of honey, the seven different floral honeys previously mentioned were successfully discriminated using the z-Nose approach. Classification models for FTIR and z-Nose were successfully validated (near 100% correct classification) using 20 samples of unknown honey from various floral sources. The developed FTIR and z-Nose methods were able to detect the floral origin of the seven different honey samples within 2-3 min based on the developed calibrations.

The sensitivity to honey of Gram-positive cocci of clinical significance isolated from wounds.

AIMS: To determine the sensitivity to honey of Gram-positive cocci of clinical significance in wounds and demonstrate that inhibition is not exclusively due to osmotic effects. METHODS AND RESULTS: Eighteen strains of methicillin-resistant Staphylococcus aureus and seven strains of vancomycin-sensitive enterococci were isolated from infected wounds and 20 strains of vancomycin-resistant enterococci were isolated from hospital environmental surfaces. Using an agar incorporation technique to determine the minimum inhibitory concentration (MIC), their sensitivity to two natural honeys of median levels of antibacterial activity was established and compared with an artificial honey solution. For all of the strains tested, the MIC values against manuka and pasture honey were below 10% (v/v), but concentrations of artificial honey at least three times higher were required to achieve equivalent inhibition in vitro. Comparison of the MIC values of antibiotic-sensitive strains with their respective antibiotic-resistant strains demonstrated no marked differences in their susceptibilities to honey. CONCLUSIONS: The inhibition of bacteria by honey is not exclusively due to osmolarity. For the Gram-positive cocci tested, antibiotic-sensitive and -resistant strains showed similar sensitivity to honey. SIGNIFICANCE AND IMPACT OF THE STUDY: A possible role for honey in the treatment of wounds colonized by antibiotic-resistant bacteria is indicated.

Use of honey as an adjunct in the healing of split-thickness skin graft donor site.

BACKGROUND: Different techniques are being used in treatment of split-thickness skin graft donor sites; however, there is not a widely accepted method established for these partial-thickness wounds. It is well known that honey has been very effective in the treatment of various types of wounds, but there is not any information about the usage of honey as split-thickness skin graft donor site dressing in the literature. OBJECTIVE: To evaluate and compare the effectiveness of honey-impregnated gauzes, hydrocolloid dressings, and as a conventional dressing, saline-soaked gauzes for skin graft donor sites. METHODS: This is a nonrandomized, prospective, open-label (noncontrolled), side-by-side comparison trial of various options that are available for second-intention healing of donor site for split-thickness skin grafts. Eighty-eight patients who underwent skin grafting were observed using two different groups. In the first group, the donor site was divided into two equal halves, with each half being treated with honey-soaked gauzes and the other half with paraffin gauzes (group 1A), hydrocolloid dressings (group 1B), and saline-soaked gauzes (group 1C) alternatively. In the second group, two separate donor sites were formed, with one of them being treated with honey-impregnated gauzes (groups 2A-C) and the other one treated with either paraffin gauzes (group 2A), hydrocolloid dressings (group 2B), or saline-soaked gauzes (group 2C). The healing time, rate of infection, and sense of pain were evaluated. RESULTS. : In the treatment of split-thickness skin graft donor sites, honey-impregnated gauzes showed faster epithelization time and a low sense of pain than paraffin gauzes and saline-soaked gauzes. There was no significant difference between honey-impregnated gauzes and hydrocolloid dressings with regard to epithelization time and sense of pain. CONCLUSION: The use of honey-impregnated gauzes is effective, safe, and practical. Honey can be an alternative material for the split-thickness skin graft donor site treatment.

Honey increased saliva, plasma, and urine content of total nitrite concentrations in normal individuals.

This study investigated effects of oral honey solution on total nitrite, a stable nitric oxide metabolite, in saliva, plasma, and urine samples collected from normal subjects. Fourteen adult healthy volunteers, 25-50 years old, nine males and three females, were enrolled in the study. Total nitrite was estimated in saliva, plasma, and urine after 14 hours of food fasting. Each subject was then asked to drink honey solution (80 g of raw honey dissolved in 250 mL of water). Saliva and blood samples were collected at 1, 2, and 3 hours after ingestion of honey solution for total nitrite assay, while urine samples were collected after 3 hours for total nitrite assay. The mean total fasting nitrite in saliva was 108 +/- 61.3 micromol/L, which was increased to 130 +/- 62.9, 131.2 +/- 59, and 135.1 +/- 64.3 micromol/L at 1, 2, and 3 hours, respectively. Plasma total nitrite was 22.41 +/- 16.22 micromol/L before drinking honey, which was increased to 34.71 +/- 18.13, 29.38 +/- 14.29, and 33 +/- 13.09 micromol/L at 1, 2, and 3 hours, respectively, after drinking honey. Urine total nitrite before drinking honey was 75.8 +/- 54.79 micromol/L, which was increased to 107.8 +/- 70.83 micromol/L 3 hours after ingestion of honey solution. Although not statistically significant, honey solution showed a tendency to increase total nitrite concentration in different biological fluids from humans, including saliva, plasma, and urine.

Honey may have a laxative effect on normal subjects because of incomplete fructose absorption.

Honey contains fructose in excess of glucose, which may lead to incomplete fructose absorption associated with abdominal symptoms and/or diarrhea. This hypothesis was investigated in 20 healthy volunteers (13 males, 7 females) with a mean (+/- SD) age of 35.9 +/- 12.1 y. Each subject drank the following aqueous solutions in random order: 20 g lactulose, 100 g honey, 50 g honey, and 35 g each of a glucose and fructose mixture. The breath-hydrogen concentration was measured every 15 min for 6 h. Semiquantitative estimates of carbohydrate malabsorption were assessed with lactose as a nonabsorbable standard. Breath-hydrogen concentrations increased by 52 +/- 6, 30 +/- 4, 20 +/- 3, and 4 +/- 1 ppm (mean +/- SEM) after each of the four test solutions, respectively. The estimated carbohydrate malabsorption was 10.3 +/- 1.8, 5.9 +/- 1.2, and 0.5 +/- 0.2 g after 100 g honey, 50 g honey, and the glucose-fructose mixture, respectively (F[2,57] = 16.05, P < 0.001). Within 10 h after the ingestion of 100 g honey, 50 g honey, and the glucose-fructose mixture, six, three and none of the volunteers, respectively, reported loose stools (chi 2 = 7.1, df = 2, P < 0.03). The results of this study suggest that carbohydrate malabsorption after ordinary doses of honey is frequent in healthy adults and may be associated with abdominal complaints. Honey may have a laxative effect in certain otherwise healthy individuals, probably because of incomplete fructose absorption.

The antibacterial activity of honey against coagulase-negative staphylococci.

OBJECTIVES: Development of antibiotic-resistant strains of coagulase-negative staphylococci has complicated the management of infections associated with the use of invasive medical devices, and innovative treatment and prophylactic options are needed. Honey is increasingly being used to treat infected wounds, but little is known about its effectiveness against coagulase-negative staphylococci. The aim of this study was to determine the minimum active dilution of two standardized, representative honeys for 18 clinical isolates of coagulase-negative staphylococci. METHODS: An agar incorporation technique was used to determine the minimum active dilution, with dilution steps of 1% (v/v) honey [or steps of 5% (v/v) of a sugar syrup matching the osmotic effect of honey]. The plates were inoculated with 10 microL spots of cultures of the isolates. RESULTS: The honeys were inhibitory at dilutions down to 3.6 +/- 0.7% (v/v) for the pasture honey, 3.4 +/- 0.5% (v/v) for the manuka honey and 29.9 +/- 1.9% (v/v) for the sugar syrup. CONCLUSIONS: Typical honeys are about eight times more potent against coagulase-negative staphylococci than if bacterial inhibition were due to their osmolarity alone. Therefore, honey applied to skin at the insertion points of medical devices may have a role in the treatment or prevention of infections by coagulase-negative staphylococci.

Free radical production and quenching in honeys with wound healing potential.

OBJECTIVES: Honey-impregnated wound dressings are now available on drug tariff in the UK, though the modes of action of honeys with antibacterial and wound healing properties are not entirely clear. The action of some but not all of these honeys is linked to the production of hydrogen peroxide on dilution of the honey with wound exudate. The present study investigates both free radical production and the antioxidant potential of some honeys, properties which may have a role to play in wound healing. METHODS: Free radical production and quenching of three honey types (manuka, antibacterial but non-peroxide-producing; pasture, antibacterial peroxide-producing; commercial heat processed, non-antibacterial) was investigated by electron paramagnetic resonance (EPR) spectroscopy; quenching was also examined using a superoxide quenching assay. RESULTS: All honeys tested had antioxidant potential, with manuka able to completely quench added radicals within 5 min of spiking. Only the peroxide-producing honey (pasture PS9) was found to form radicals on dilution. CONCLUSIONS: The ability to modulate production and quenching of free radicals may contribute to the demonstrated ability of some honeys to help in resolving the state of inflammation typifying chronic wounds.

Substituting honey for refined carbohydrates protects rats from hypertriglyceridemic and prooxidative effects of fructose.

Recent findings indicate that a high fructose diet has a prooxidant effect in rats compared with a starch diet. Because honey is rich in fructose, the aim of this study was to assess the effect of substituting honey for refined carbohydrates on lipid metabolism and oxidative stress. Rats were fed for 2 wk purified diets containing 65 g/100 g carbohydrates as wheat starch or a combination of fructose and glucose or a honey-based diet prepared by substituting honey for refined carbohydrates (n = 9/group). The same amount of fructose was provided by the honey and fructose diets. The hypertriglyceridemic effect of fructose was not observed when fructose was provided by honey. Compared with those fed starch, fructose-fed rats had a lower plasma alpha-tocopherol level, higher plasma nitrite and nitrate (NOx) levels and were less protected from lipid peroxidation as indicated by heart homogenate TBARS concentration. Compared with those fed fructose, honey-fed rats had a higher plasma alpha-tocopherol level, a higher alpha-tocopherol/triacylglycerol ratio, lower plasma NOx concentrations and a lower susceptibility of heart to lipid peroxidation. Further studies are required to identify the mechanism underlying the antioxidant effect of honey but the data suggest a potential nutritional benefit of substituting honey for fructose in the diet.

A survey of the antibacterial activity of some New Zealand honeys.

To assess the variation in antibacterial activity of honey a survey was carried out on 345 samples of unpasteurized honey obtained from commercial apiarists throughout New Zealand. Most of the honeys were considered to be monofloral, from 26 different floral sources. The honeys were tested against Staphylococcus aureus in an agar well diffusion assay, with reference to phenol as a standard. Antibacterial activity was found to range from the equivalent of less than 2% (w/v) phenol to 58% (w/v) phenol, with a median of 13.6 and a standard deviation of 12.5. Neither the age of the honey samples nor whether they had been processed by the apiarist was associated with lower activity. However, the difference between floral sources in the antibacterial activity was very highly significant. Kanuka (Kunzea ericoides (A. Rich.) J. Thompson. Family: Myrtaceae), manuka (Leptospermum scoparium J. R. et G. Forst. Family: Myrtaceae), ling heather (Calluna vulgaris (L.) Hull. Family: Ericaceae) and kamahi (Weinmannia racemosa Linn. f. Family: Cunoniaceae) were shown to be sources likely to give honey with high antibacterial activity. When antibacterial activity was assayed with catalase added to remove hydrogen peroxide, most of the honeys showed no detectable antibacterial activity. Only manuka and vipers bugloss (Echium vulgare L. Family: Boraginaceae) honeys showed this type of activity in a significant proportion of the samples. The high antibacterial activity of manuka honey was in many cases due entirely to this non-peroxide component.

Enhanced wound contraction in fresh wounds dressed with honey in Wistar rats (Rattus Novergicus).

BACKGROUND: Due to reports that honey accelerates wound healing, an investigation on its role in wound contraction in fresh wounds inflicted on wistar rats was carried out. METHOD: Twenty adult male wistar rats had 2cm by 2cm square wound inflicted on their right dorsolateral trunk. They were divided into two groups. The experimental group had their wounds dressed with honey while the control group had normal saline dressing. Wound dressing was done every five days and measurements taken at each dressing. Wound morphology was also assessed. RESULTS: Dressing with honey significantly enhanced percentage wound contraction on day 10 with value of 79.20+/-2.94 compared to control value of 53.50+/-4.32. p=0.0. The mean wound measurement on day 10 reduced significantly in honey group, 1.15+/-0.18 compared to control group 2.38+/-0.28. p=0.002. However, there was no significant difference in fibroblast count per high power field in honey group 68.0+/-2.59 compared to control 90.2+/-17.40, p=0.242. Honey dressing increased mean blood vessel count per high power field, 18.8+/-3.77 albeit non significantly when compared to control value of 13.4+/-2.44, p=0.264. Also honey dressing caused increased granulation tissue formation in wounds dressed with honey compared to control group. CONCLUSION: Our study suggests that honey dressing enhances wound contraction in fresh wounds which is one of the key features of wound healing.

Investigation of in vitro antimicrobial activity of honey.

Apitherapy or therapy with bee products as honey is an old tradition. In this study, the antimicrobial activity of 84 honey samples were investigated against 8 bacteria potential pathogens and 2 fungi. Honey samples were obtained from 10 different floral sources. The findings indicate that honey samples with thyme, thyme + acorn, pine + carob, pine + carob + anis and pine + chestnut are more effective than the other honey of floral sources. The results of the survey show that most of honey samples at 50% (w/v) can completely inhibit the growth of all of the tested bacteria. The fungi were less sensitive than the bacteria to the antimicrobial activity of honey. The sensitivity of microorganisms to sugar solutions with similar sugar contents as some honey samples which have high antimicrobial activity were also assayed. This sugar solutions inhibited a narrow range of bacteria and did not inhibit any of the fungi tested. In conclusion, these results encourage further studies to investigate possible benefits of the use of honey among therapies in the treatment of bacterial infections.

Evaluating the inhibitory action of honey on fungal growth, sporulation, and aflatoxin production.

Unprocessed honey was inoculated with toxigenic strains of Aspergillus flavus NRRL 5862 and A. parasiticus NRRL 2999. The fungi grew and sporulated in varying amounts of honey diluted with water, but none of the cultures produced detectable levels of aflatoxin. Growth and subsequent sporulation were seen only in media containing up to and including 60% of honey. Media having 40% of honey showed growth and sporulation by day two. Neither species of Aspergillus produced toxins even in 10% honey. These results confirm our earlier observations that pure honey inhibited fungal growth and now even diluted honey seems capable of inhibiting toxin production or possibly neutralizing it. The general procedures recommended by the AOAC for extraction and thin layer chromatography were applied successfully in analyzing the honey substrate for aflatoxin.

Metabolic effects of honey (alone or combined with other foods) in type II diabetics.

The metabolic effects of honey - alone or combined with other foods - were investigated in type II diabetics using 2 protocols: A) 33 g honey and 50 g bread (same amounts of carbohydrate) were given on alternate days to 12 patients. Blood levels of glucose, insulin and triglycerides were determined in venous samples before and every 30 min after meal ingestion (for a total of 3h). Areas under glucose curves were equal, although honey - compared to bread - resulted in higher blood sugar concentrations at 30 min (p less than 0.01) and lower at 90 min (p less than 0.05). B) Another 19 type II diabetics consumed on separate days 3 different meals: H (30 g honey), HA (30 g honey, 100 g almonds), HB (30 g honey, 125 g cheese, 10 g bread, 10 g butter). HA and HB contained the same amount of fat, but were different in fiber. No significant differences in the areas under glucose curves were observed. However, meal H produced earlier hyperglycemia than HA and HB (30 min: p less than 0.01). Insulin levels were higher after HB compared to H (p less than 0.05). Meals HA and HB were followed by higher triglyceride levels than H (p less than 0.05). It is concluded that: 1) honey and bread produce similar degrees of hyperglycemia in type II diabetics. 2) Fat-rich foods added to honey do not alter the total hyperglycemic effect but result in higher triglyceride and insulin serum concentrations.
