The Technology and Composition of Functional Food Ingredients Obtained by Sorption of the Polyphenolic Compounds From Cranberry on Coagulated Egg Albumen


The technologies for developing food products for people with type 2 diabetes involve enrichment with polyphenolic compounds that have hypoglycemic and/or hypolipidemic properties. The production of ingredients for introduction into such food products should involve the techniques of concentration of natural polyphenols on certain food-grade protein matrices. In this study, a technology was developed for the production of a functional food ingredient, which was a complex of polyphenols (mostly anthocyans) from cranberries with coagulated egg albumen. The optimal parameters of sorption of anthocyans from cranberry juice on the albumen during the coagulation of the latter were determined. The contents and profile of anthocyans within the resulting food ingredient were assessed. The concentration of total anthocyans (recalculated to equivalents of cyanidin-3-glucoside) was determined by pH-differential spectrophotometry; the profile of individual anthocyans was determined by highperformance liquid chromatography. Sensory evaluation of the resulting ingredient (through a taste panel test) evidenced the possibility of including the product in the functional foodstuffs. The technology developed can be used in the design of functional food ingredients for subsequent introduction into anti-diabetic food products.
