摘要:
Es wird ein Verfahren zum Behandeln von Lebensmitteln, insbesondere auf pflanzlicher Basis, wie Gemüse, Salat, Obst und dergleichen, vorgeschlagen, wobei die Lebensmittel gewaschen und desinfiziert werden. Um für eine einwandfreie und gesundheitlich unbedenkliche Desinfektion der Lebensmittel unter Vermeidung einer oxidativen Beeinträchtigung derselben zu sorgen, sieht das erfindungsgemäße Verfahren die folgenden Schritte vor: a) Bereitstellen einer insbesondere wäßrigen Lösung eines oxidativ wirksamen, hypochlorige Säure (HOC1) und/oder Hypochlorit (OCl - ) enthaltenden Desinfektionsmittels; b) Bereitstellen einer insbesondere wäßrigen Lösung wenigstens eines gesundheitlich unbedenklichen Reduktionsmittels und/oder Antioxidationsmittels, wobei das Reduktions- bzw. Antioxidationsmittel eine hinreichende Konzentration aufweist, um die oxidative Wirkung des Desinfektionsmittels zu neutralisieren; c) zunächst Inkontaktbringen der Lebensmittel mit dem Desinfektionsmittel in unverdünnter oder verdünnter Form; und d) sodann Inkontaktbringen der Lebensmittel mit der Lösung des Reduktions- bzw. Antioxidationsmittels. Anschließend können die Lebensmittel z.B. getrocknet und gegebenenfalls verpackt werden.
摘要:
A polyphenoic antioxidant-enhanced comestible composition and method for making it are disclosed. The antioxidant -enhanced comestible preferably includes an astringent amount of exogenous polyphenolic antioxidant dissolved or dispersed in a precursor edible product. The composition also includes an effective concentration of at least one astringency compensating or masking agent sufficient to offset the astringency contributed by the exogenous polyphenolic antioxidant compounds, and can also include an effective amount of at least one protective agent that protects polyphenolic antioxidants from premature oxidation.

摘要:
Food products, such as precooked meats, raw meats, and poultry are treated with a decontaminant solution to remove surface microorganism contamination. The decontaminant solution contains peracetic acid at a concentration of from about 100 to 4000 ppm and has broad spectrum activity against a variety of pathogenic and spoilage microorganisms, such as Listeria monocytogenes .
摘要:
A process for isolating polyphenolic antioxidants from purine-containing plant material, comprising the steps of: (a) extracting the plant material with a hydroxylic extracting liquid preferably at low temperature; (b) selectively adsorbing the extract obtained in step (a), preferably at low temperature; and (c) desorbing the adsorbed material with a hydroxylic desorbing liquid, preferably at relatively high temperature. The process is especially suitable for producing cocoa antioxidants of use in pharmaceutical, cosmetic and nutritional compositions.
