Removal of electrolytes from institutionally packaged foods.

Soaking and rinsing resulted in significant (p less than .01) reductions in sodium and potassium concentrations of peeled potatoes and hard-cooked eggs packed in brines containing sodium compounds and packaged for institutional use. In this study, no significant differences (p greater than .01) were found between soaking and rinsing in deionized water and in tap water; however, tap water can vary greatly in sodium and potassium content. Sodium and potassium levels of chopped lettuce dipped in sodium hypochlorite were not significantly (p greater than .01) affected by soaking and rinsing procedures. However, the sodium and potassium levels of the processed lettuce were not high relative to the levels of unprocessed lettuce before soaking and rinsing.

A prospective study comparing oral sodium phosphate solution to a bowel cleansing preparation with nutrition food package in children.

OBJECTIVE: The inability of children to comply with bowel preparation regimens can result in inadequate visualization of the colon. This study compares the safety, efficacy, and patient acceptance of a prepackaged diet kit plus a magnesium citrate/bisacodyl bowel cleansing regimen with a clear liquid diet and sodium phosphate solution regimen in children undergoing colonoscopy. METHODS: Children scheduled for a diagnostic colonoscopy, were randomly assigned to receive a prepackaged diet kit and a magnesium citrate/bisacodyl laxative (group 1), or clear liquids and sodium phosphate solution (group 2). The patients and their parents completed a questionnaire to evaluate acceptance of their assigned regimen before colonoscopy. The endoscopists, blinded to the type of bowel preparation, rated bowel cleansing. RESULTS: Sixty two children (28 males, 34 females) with mean age 12.5 years participated. Thirty six and 26 patients were in groups 1 and 2 respectively. Overall cleansing was rated significantly superior in group 1 compared to group 2 as was amount of retained feces (P = .013 for both). The overall frequency of reported side-effects was lower in group 1 than (83.3%, 30/36) than in group 2 (100.0%, 26/26) (P = 0.03). The preparations were otherwise equivalent in regards to compliance and patient tolerance. CONCLUSIONS: Although both regimens were comparable in adequacy of colon visualization, preparation tolerance, side effects and compliance profile in this pilot study, the prepackaged diet kit with magnesium citrate/bisacodyl laxative resulted in superior colon cleansing.

A multiresidue approach to the identification of food packaging-derived volatiles in foods and containers.

A rapid approach to the tentative identification of food packaging-derived volatile residues in foods and containers by use of headspace sampling, capillary gas chromatography, and a computer data search program is described. Headspace vapors of samples are analyzed on Ov-101 and Carbowax 20M columns. Peak retention time data of a sample on both columns are compared with those of common packaging raw materials, by-products, and processing agents maintained in a standard reference file. A list of possible identities based on the chromatographic peaks is compiled and printed out. Additional supporting data, such as relative peak response on each column, are examined to make a tentative identification. Other methods must be employed to confirm these identifications.

Production and applications of biobased packaging materials for the food industry.

Materials based on renewable resources are being developed at an increasing rate. Today, the only biobased food-packaging materials used commercially on a major scale are based on cellulose. However, materials based on proteins, starch, polylactate and other renewable resources may be the food-packaging materials of tomorrow. The paper presents some of the different biobased materials and their potential as food-packaging materials.

Food and packaging interactions: tailoring fatty food simulants.

Migration of paramagnetic probes from rigid PVC within 24 h at 50 degrees C depends on the simulant to a considerable extent. With a strongly swelling simulant like tert.butyl acetate, the rate of diffusion is governed by the rate of penetration of the medium into the polymeric network. Isooctane has a very weak interaction with rigid PVC. With a mixture of tert.butyl acetate and isooctane it is possible to adjust the aggressivity of the medium and to tailor an alternative simulant that interacts with the polymer in the same fashion as the EU's official fatty food simulants. Particular responses of polar probes underline the importance of the interaction between simulant and additives in the choice of alternative fatty food simulants for rigid PVC.

Identification of 8-nonenal as an important contributor to "plastic" off-odor in polyethylene packaging.

Food and beverage products stored in polyethylene (PE) containers may absorb some of PE's volatile minor components and become tainted by its characteristic "plastic" odor. High-density PE containers that had imparted "plastic" odor to an experimental corn chip product were analyzed by simultaneous distillation/extraction to remove the volatile components, by gas chromatography/olfactometry (GC/O) to locate the offending components and by 2-D GC/mass spectrometry (MS) to identify the major "plastic" odor contributor (8-nonenal). The identification was made using high-resolution electron ionization and chemical ionization MS data to narrow the possibilities to two isomers of nonenal, followed by retrieval of reference spectra and confirmatory synthesis. By monitoring 8-nonenal in HDPE containers and corn chips it was demonstrated that 8-nonenal tracks with "plastic" aroma observed in containers and with "plastic" flavor observed in corn chips stored in the containers.
