Problematic occurrence of tyrosine crystals in the thai soybean paste tao chieo.

In a Bangkok soy sauce factory that had recently converted to controlled inoculum and incubation for the koji stage of fermentation, a problem arose with unsightly white particles in the soybean paste condiment called tao chieo. This problem had not arisen during the previous history of the factory where the koji stage of the fermentation was uncontrolled. Microscopic examination of the particles showed that they were crystalline. Physical separation of the crystals followed by solvent extraction, recrystallization, chemical characterization, and spectroscopy showed that they consisted of tyrosine. Tao chieo prepared by using low- or high-protease strains of Aspergillus sp. indicated that the tyrosine crystals resulted from mold proteolysis of the soybean substrate. Addition of polyethylene glycol at the beginning of the moromi fermentation reduced the severity of crystal formation.

Selections from the buffet of food signs in radiology.

Certain pathologic conditions have classic radiologic manifestations that resemble various types of food. These "food signs" are highly memorable and easily recognizable and include findings that resemble various fruits and vegetables; meat, fish, and egg dishes; pasta, rice, grains, and bread (carbohydrates); desserts, cakes, and candy; and dishes, cutlery, condiments, and so on. It is important that radiologists recognize these classic signs, which will allow confident diagnosis on the basis of imaging findings alone or narrowing of the differential diagnosis.

1'-acetoxychavicol acetate is a novel nuclear factor kappaB inhibitor with significant activity against multiple myeloma in vitro and in vivo.

1'-Acetoxychavicol acetate (ACA) is a component of a traditional Asian condiment obtained from the rhizomes of the commonly used ethno-medicinal plant Languas galanga. Here, we show for the first time that ACA dramatically inhibits the cellular growth of human myeloma cells via the inhibition of nuclear factor kappaB (NF-kappaB) activity. In myeloma cells, cultivation with ACA induced G0-G1 phase cell cycle arrest, followed by apoptosis. Treatment with ACA induced caspase 3, 9, and 8 activities, suggesting that ACA-induced apoptosis in myeloma cells mediates both mitochondrial- and Fas-dependent pathways. Furthermore, we showed that ACA significantly inhibits the serine phosphorylation and degradation of IkappaBalpha. ACA rapidly decreased the nuclear expression of NF-kappaB, but increased the accumulation of cytosol NF-kappaB in RPMI8226 cells, indicating that ACA inhibits the translocation of NF-kappaB from the cytosol to the nucleus. To evaluate the effects of ACA in vivo, RPMI8226-transplanted NOD/SCID mice were treated with ACA. Tumor weight significantly decreased in the ACA-treated mice compared with the control mice. In conclusion, ACA has an inhibitory effect on NF-kappaB, and induces the apoptosis of myeloma cells in vitro and in vivo. ACA, therefore, provides a new biologically based therapy for the treatment of multiple myeloma patients as a novel NF-kappaB inhibitor.

Food choices for lowering sodium intake.

Excessive intake of dietary sodium is one form of affluent or industrial society malnutrition. When combined with a genetic-based sodium sensitivity, this high sodium intake becomes a factor in the etiology of hypertension. Most dietary sodium comes from food, natural of processed. Indirect measures of discretionary sodium intake, that from the salt shaker in the kitchen or at the table, put it at a level of 25% to 50% in the United States. Direct measures on a small sample of subjects indicate that less than 10% of sodium intake is discretionary. Anyone who needs to reduce sodium intake must, therefore, make major changes in diet. This requires information on the sodium content of common foods, the availability of low sodium analogs of popular foods, and a variety of low sodium condiments to provide more choice for the individual.

Knowledge of consumers regarding the nature and extent of adulteration of Indian foods.

The present study was carried out on 60 women consumers selected from three different localities of Hisar city in India to study their knowledge regarding adulteration and detecting adulterants in commonly used food items. The post exposure correct responses of the respondents increased remarkably as 100.0 percent of the respondents gave correct responses regarding statements on adulteration of spices and condiments, the most common adulterated food item and to when and whom they could approach for making complaints about adulterated foods. Similarly, the respondents gained considerable knowledge regarding adulterants generally present in milk, legumes and definition of food adulteration. All the food samples except gene collected from the households of the respondents were found to be adulterated. The main adulterants in milk was water (70.0 percent); turmeric powder contained chalk powder (43.3 percent); chillies powder had artificial colour (100.0 percent); essential oils were removed from cardamom (36.6 percent); green gram and urd bean had water soluble colours; chick pea flour had artificial colours (70.0 percent) and chalk powder was present in sugar (36.6 percent). A kit was developed, tested and given to the housewives so that they could detect adulterants in commonly used food items at the household level.

IgE-mediated food allergy--extensive review of the literature.

Adverse reactions to food, i.e. food allergy and intolerance have gained considerable attention. This overview focuses on the diagnosis and management of IgE-mediated food allergy that is believed to be responsible for most immediate-type food-induced hypersensitivity reactions. Clinically, these reactions are characterised by a variety of signs and symptoms that occur within minutes or hours after consumption of the offending food. Reactions may be limited or more generalised with involvement of the skin, nose, eyes, and/or lungs. In more severe cases, cardiovascular symptoms including hypotension, shock, cardiac dysrhythmias and death can occur. In food-allergic individuals, IgE is produced against naturally occurring food components, primarily glycoproteins that usually retain their allergenicity after heating and/or proteolysis. While adults tend to be allergic to fish, crustaceans, peanuts and tree nuts, children tend to be allergic to cow's milk, egg white, wheat and soy more frequently. "Emerging" food allergens include tropical fruits, sesame seeds, psyllium, spices and condiments. These allergies frequently represent a cross-allergy to an allergen derived from another source, e.g. pollens or natural rubber latex. The evaluation of IgE-mediated food allergy relies on a careful history, physical examination, appropriate skin testing or in vitro testing with food extracts, and/or double blind, placebo-controlled food challenges. Avoidance remains the mainstay of therapy. However, allergens may be "hidden" and labelling can be non-precise or misleading, thereby severely hampering prevention. Patients with severe allergies should keep at hand an emergency kit with adrenaline, an antihistamine and an injectable rapid onset-of-action corticosteroid. At present there is no evidence to support the use of immunotherapy, except for research purposes. Production of "hypoallergenic" food is hampered by incomplete methods for assessing the allergenic potential of such novel foods.

Colon cancer proliferating desulfosinigrin in wasabi (Wasabia japonica).

A reduced incidence of different types of cancer has been linked to consumption of Brassica vegetables, and there is evidence that glucosinolates (GSLs) and their hydrolysis products play a role in reducing cancer risk. Wasabi (Wasabia japonica) and horseradish (Armoracia rusticana), both Brassica vegetables, are widely used condiments both in Japanese cuisine and in the United States. Desulfosinigrin (DSS) (1) was isolated from a commercially available wasabi powder and from fresh wasabi roots. Sinigrin (2) was isolated from horseradish roots. DSS and sinigrin were evaluated for their inhibitory effects on cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, on lipid peroxidation, and on the proliferation of human colon (HCT-116), breast (MCF-7), lung (NCIH460), and central nervous system (CNS, SF-268) cancer cell lines. DSS did not inhibit COX enzymes or lipid peroxidation at 250 microg/ml. Sinigrin inhibited lipid peroxidation by 71% at 250 microg/ml. However, DSS promoted the growth of HCT-116 (colon) and NCI H460 (lung) human cancer cells as determined by the MTT assay in a concentration-dependent manner. At 3.72 microg/ml, a 27% increase in the number of viable human HCT-116 colon cancer cells was observed; the corresponding increases at 7.50 and 15 microg/ml were 42 and 69%, respectively. At 60 microg/ml, DSS doubled the number of HCT-16 colon cancer cells. For NCI H460 human lung cancer cells, DSS at 60 microg/ml increased the cell number by 20%. Sinigrin showed no proliferating effect on the tumor cells tested. This is the first report of the tumor cell-proliferating activity by a desulfoglucosinolate, the biosynthetic precursor of GSLs found in Brassica spp.

Amyotrophic lateral sclerosis and parkinsonian syndromes in high incidence among the Auyu and Jakai people of West New Guinea.

Amyotrophic lateral sclerosis (ALS) and parkinsonism-dementia (PD) occur in the highest recorded incidence among primitive Auyu and Jakai people on the southern coastal plain of West New Guinea, in association with a heretofore unrecognized subacute, often recurrent, paralytic "poliomyeloradiculitis" (PMR). Ninety-seven cases of ALS, 19 cases of PD and 18 cases of PMR were recorded, with mean ages of onset of 33, 43, and 26, respectively, in a small affected population of only about 7000. The ecology, culture, and diet of the remote, primitive ALS- and PD-affected people are indistinguishable from that of their unaffected neighbors, except for a remarkable deficiency of calcium and magnesium in their soil and drinking water. The distribution of affected and nonaffected villages indicates that communicable infectious or genetic etiology is unlikely. As a result of the isolation and primitive technology, domestic animals (except dogs and pigs) were not found among the Auyu and Jakai, and no manufactured products (including metals, ceramics, textiles, petrochemicals, medicines, food additives, condiments, paints, dyes, or solvents) were available to them.

Anti-ulcer effect in rats of bitter cardamon constituents.

The effects of bitter cardamon (the fruit of Alpinia oxphylla), used as a medicine and a condiment, on HCl/ethanol-induced gastric lesions in rats were examined. The acetone extract at 50 mg/kg, p.o. significantly inhibited gastric lesions by 57.0%. An analysis of the active constituents in the acetone extract was performed using column chromatography. Nootkatone at 20 mg/kg, p.o. significantly inhibited gastric lesion. These results suggest that nootkatone, the sesquiterpenoid is an important constituent in stomach medications containing bitter cardamon.

[New pharmacological activities of garlic and its constituents].

According to the recent pharmacological findings, garlic is a preventive rather than therapeutic. Epidemiological studies in China, Italy and USA showed the inverse relationship between stomach and colon cancer incidences and dietary garlic intake. Anti-carcinogenic activities of garlic and its constituents including sulfides and S-allyl cysteine, have been demonstrated using several animal models. Garlic preparations has been also shown to lower serum cholesterol and triglyceride levels, which are major risk factors of cardiovascular diseases, through inhibition of their bio-synthesis in the liver, and to inhibit oxidation of low density lipoprotein. Furthermore, in vitro and in vivo studies have revealed that aged garlic extract stimulated immune functions, such as proliferation of lymphocyte, cytokine release, NK activity and phagocytosis. More recently, aged garlic extract has been demonstrated to prolong life span of senescence accelerated mice and prevent brain atrophy. Manufacturing processes significantly affect chemical constituents in garlic preparations. Different forms contain different phytochemicals and may have different effects and toxicities. For example, aged garlic extract inhibited t-BuOOH-induced oxidation, whereas raw garlic stimulated the oxidation. Although garlic has been used as a condiment and folklore for a long time, it has been noted to cause adverse reactions, such as stomach ulcer and anemia. Among the garlic preparations, only aged garlic extract has been proven to be safe through toxicological studies. Thus, aged garlic extract could be the most promising garlic preparation for disease prevention.

Effects of polysaccharides from rhizomes of Curcuma zedoaria on macrophage functions.

The effects of Curcuma zedoaria, which is used as a condiment, in perfumery, and as a medicine, on immune response were investigated by measuring macrophage-stimulating activity in macrophages and RAW 264.7 cells. In this study, CZ-1 and CZ-1-III, the fractions partially purified from C. zedoaria, had a strong, dose-dependent lysosomal enzyme activity. It was suggested that active portions of CZ-1-III were polysaccharides rather than proteins. Phagocytic activity increased as a similar pattern in both the gram-negative and gram-positive bacteria, time-dependently. It was demonstrated that CZ-1-III can augment the oxygen burst response but had an even higher activity in vivo than in vitro. Also a significant increase of H2O2, NO, and TNF-alpha production was observed. However, the production of TNF-alpha at the concentration of 1,000 microg/ml decreased. These data suggested that C. zedoaria had macrophage-stimulating activity and the possibility of being used as a biological response modifier.

Induction of liver monooxygenases by annatto and bixin in female rats.

Annatto or urucum is an orange-yellow dye obtained from Bixa orellana seeds. It has been used as a natural dye in a variety of food products, drugs and cosmetics, and also in Brazilian cuisine as a condiment ('colorau'). Bixin, a carotenoid devoid of provitamin A activity, is the main pigment found in annatto. Some carotenoids (canthaxanthin, astaxanthin and beta-Apo-8'-carotenal) are known to be potent inducers of CYP1A1, a property not shared by others (beta-carotene, lycopene and lutein). Little is known, however, about the CYP1A1-inducing properties of bixin and annatto. The present study was performed to determine the effects of an annatto extract (28% bixin) and bixin (95% pure) on rat liver monooxygenases. Adult female Wistar rats were treated by gavage with daily doses of annatto (250 mg/kg body weight, which contains approximately 70 mg bixin/kg body weight), bixin (250 mg/kg body weight) or the vehicle only (corn oil, 3.75 g/kg body weight) for 5 consecutive days, or were not treated (untreated control). The activities of aniline-4-hydroxylase (A4H), ethoxycoumarin-O-deethylase (ECOD), ethoxy- (EROD), methoxy- (MROD), pentoxy- (PROD) and benzyloxy- (BROD) resorufin-O-dealkylases were measured in liver microsomes. Annatto (250 mg/kg containing 70 mg bixin/kg) induced EROD (3.8x), MROD (4.2x), BROD (3.3x) and PROD (2.4x). Bixin (250 mg/kg) was a weaker inducer of EROD (2.7x), MROD (2.3x) and BROD (1.9x) and did not alter PROD, A4H or ECOD activities. These results suggest that constituents of the extract other than bixin play an important role in the induction of CYP1A and CYP2B observed with annatto food colorings.

Trained sensory panel and consumer evaluation of the effects of gamma irradiation on palatability of vacuum-packaged frozen ground beef patties.

The objectives for this experiment were to determine the effects of gamma irradiation on 1) the palatability of vacuum-packaged frozen ground beef patties by trained sensory panel and 2) consumer evaluation of the taste of hamburgers made with those patties. Boxes (4.5 kg) of frozen (-28 degrees C) ground beef patties (113.4 g/patty, 19% fat) from a commercial supplier were irradiated at a commercial gamma irradiation facility at one of three levels (0, 3.0, or 4.5 kGy). All boxes were stored at 28 degrees C for 27 to 29 d after irradiation before evaluation by a trained descriptive attribute sensory panel and for 62 to 104 d after irradiation before consumer evaluation. The trained panel evaluated grilled patties for ground beef aroma intensity, off-aroma, and off-flavor on 4-point scales (4 = intense, none, and none; 1 = none, intense, and intense, respectively) and ground beef flavor intensity, tenderness, and juiciness on 8-point scales (8 = extremely intense, tender, or juicy; 1 = extremely bland, tough, or dry). Control patties had more intense (P<.05) ground beef aroma (3.1 vs 2.6), less off-aroma (3.3 vs 2.6), and more intense ground beef flavor (4.9 vs. 4.3) than irradiated patties. However, there were no differences (P>.05) in any sensory trait between frozen ground beef patties treated with 3.0 or 4.5 kGy of gamma irradiation. There were no differences (P>.05) among treatments for tenderness (6.3, 6.6, and 6.7) or juiciness ratings (5.7, 5.9, and 5.9), respectively, for 0, 3.0, and 4.5 kGy. The consumers evaluated taste of a hamburger that included their choice of condiments on a 10-point scale (10 = excellent; 1 = terrible). Hamburgers made with patties treated with 4.5 kGy were rated lower (P<.05) in taste than hamburgers made with either control patties or those treated with 3.0 kGy (6.5, 6.6, and 6.2, respectively, for 0, 3.0, and 4.5 kGy); however, all doses were rated at some level of "fair." These results imply that hamburgers made from ground beef patties irradiated under the conditions of this experiment would encounter little, if any, consumer acceptance problems at the 3.0 kGy dose and only slightly greater problems at the 4.5 kGy dose.

Development by extrusion of soyabari snack sticks: a nutritionally improved soya-maize product based on the Nigerian snack (kokoro).

A nutritionally improved local snack compared to existing kokoro has been developed by extrusion cooking of different formulations of maize, soybean and condiments such as pepper, onion, salt, palm oil, plantain and banana. The improved snack was named as the 'soyabari snack stick'. The chemical composition of representative extruded products indicates a high level of crude protein, fat, energy, available lysine and improved in vitro digestibility compared to the usual maize-based products. The level of stachyose and raffinose were greatly reduced in the extruded products compared to raw soya. Formulations using various additives yielded products suitable for different consumers' preferences such as hot, sweet, bland, gritty or crispy and acceptable to taste assessors. Soyabari snack sticks were equally acceptable as Bombay mix, a product on the market in London. Sensory analysis showed no significant differences in the two products but the crude fibre content of Bombay mix was higher while the protein was slightly lower than for soyabari sticks. Local ingredients can produce acceptable extrudates.

A case-control study of colorectal adenomatous polyps and consumption of foods containing partially hydrogenated oils.

The trans fatty acids produced by partially hydrogenating vegetable oils may cause colorectal neoplasia by interfering with cell membrane function or eicosanoid synthesis. This possibility provides a rationale for looking at the relation between colorectal adenomatous polyps and consumption of foods containing partially hydrogenated vegetable oils (PHVOs). A total of 516 cases and 551 controls who underwent screening sigmoidoscopy from 1991-1993 were recruited from a prepaid Los Angeles health plan. Subjects were interviewed and given a self-administered food frequency questionnaire. Food items containing PHVOs were divided into four groups characterized by principal ingredients and preparation methods: sweetened baked goods, candy bars, oils and condiments, and french fries and chips. After adjusting for age, sex, physical activity, body mass index, smoking, total energy, and red meat and vegetable intake, there was a positive association between polyps and sweetened baked goods [350+ versus <50 kcal/day (odds ratio, 2.1; 95% confidence interval, 1.3-3.5)]. No association was found with the other food groups after adjustment for dietary and nondietary covariates. Neither was total dietary trans fatty acid associated with adenomas after adjustment for sweetened baked goods and other covariates. These results do not support the hypothesis that eating foods containing PHVOs increases the risk of colorectal adenomas, but they are consistent with the hypothesis that foods high in fat and sugar and low in fiber and correlated micronutrients increase the risk of adenomas.

[New food allergies].

RISING INCIDENCE OF FOOD ALLERGIES: Food allergies are becoming more and more common, concerning 3 to 4% of the general population. One out of four persons allergic to nuts, the most frequent food allergen, have severe signs and symptoms. A CLASSICAL DIAGNOSIS: Certain diagnosis of food allergy is established on the basis of labial and oral tests. The dose required to induce a reaction is established by the oral test, giving information about the severity of the allergy and its progression. OTHER ALLERGENS: "Emerging" food allergens include spices and condiments, exotic fruits (kiwi, avocado, cashew and pecan nuts, Brazil nuts), sesame seeds, psyllium, sunflower seeds. Endurance exercise following ingestion of a food allergen can lead to severe anaphylactic reactions. Allergen associations "food-pollen", "latex-food", "mitessnails" have been described. INDISPENSABLE PREVENTION: Avoiding contact is essential. Many allergens are "masked" within prepared foods. Precise labeling, with particular attention to nut content, must be reinforced. Individualized counseling on food allergies should be available for school children. Persons with severe allergies should keep at hand an emergency kit with antihistamines, injectable rapid action corticoids and adrenalin (1 mg/ml).

[Mineral composition of edible mushrooms cultivated in Brazil--Pleurotus spp and other dehydrated species].

Macrofungi can accumulate some minerals, including toxic metals if present in the substrate. A periodic monitoring of these elements in mushrooms is recommended when the conditions of cultivation are altered. The aim of this work was to evaluate the mineral content of Pleurotus spp (hiratake and shimeji) and of imported (chilean and italian) dehydrated mushrooms. Fresh fruiting bodies of Pleurotus spp were obtained from cultivators and dehydrated mushrooms were bought in a market. The samples were dried, milled and digested by C1H-NO3H. The content of P, K, S, Ca, Mg, Cu, Fe, Mn, Zn, Na and B were analyzed by ICP-AES and Al, Cd, Cr, Pb, Co, Ni by ICP-OES. The results classify these mushrooms as a source of potassium and copper: Pleurotus spp are also a source of phosphorus (P < 0.05); the chilean mushrooms present high content of iron (P < 0.05). All the evaluated mushrooms were identified as a food without sodium (< 5 mg Na/100 g). So these mushrooms being a source of potassium without Na, answer the needs of hypertension and/or heart diseases patients as a food and/or like a condiment for flavor enhancement. Subsequent studies should include major sampling and the evaluation of the toxic metals, Pb and Cr, employing more accurate methods of analysis, as well as the evaluation of Hg (not analysed in this study), mainly in wild mushrooms, commercialized dehydrated.

Haemodynamic effects of pan masala in healthy volunteers.

OBJECTIVES: We studied acute haemodynamic effects of pan masala (powdered mixture of areca nut, slaked lime, catechu, and condiments) in healthy volunteers. METHODS: Fifty one males (mean age 28.6 +/- 10 years) were evaluated. One pouch (4 g) of pan masala without tobacco was given to each subject under fasting state and effects on pulse and blood pressure (BP) recorded. RESULTS: At baseline the pulse rate was 75.1 +/- 9.0 per minute, systolic BP was 119.1 +/- 10.8 mm Hg, and diastolic BP was 78.0 +/- 7.5. The pulse rate increased to 87.5 +/- 11.4 at ten minutes (+16.9 +/- 12.6%, p < 0.001) and fell to 76.7 +/- 9.1 at 30 minutes (p = ns). Systolic BP increased to 122.3 +/- 11.7 mm Hg at 10 minutes (+2.73 +/- 5.1%, p < 0.001) and was 120.8 +/- 10.8 at 30 minutes; while diastolic BP was 80.8 +/- 7.3 at 10 minutes (+3.83 +/- 6.1%, p < 0.001) and 79.4 +/- 7.6 at 30 minutes. CONCLUSIONS: Pan masala intake causes acute increase in pulse and BP.
