Multipurpose Antioxidants based on Food Industry Waste: Production and Properties Evaluation

Some preliminary results of studies on the assessment of the possibilities and prospects for obtaining products with a high Antioxidant Activity Index (AOA) from the waste of the coffee beverage production industry - "silver skin" (SC, silverskin, CS) are presented. The obtained data on the extraction of SC with aqueous-alcoholic extractants, the effect of extraction conditions on the yield of extracts, and extractive substances are discussed. It is reported on the production of dry powders of extracts that retain their properties during long-term storage. Data on the antioxidant properties of both liquid and dry forms of extracts are presented and good AOA of the studied objects is noted in comparison with the "standard" antioxidant - rosemary extract, and it is also shown that the AOA of dry forms of extracts can be increased by doping with synergists - polyphenols of natural genesis. The antioxidant activity of the obtained compositions was studied on real objects - animal fats and natural dyes, the results of which confirmed the prospects of the studied antioxidants (AO) for practical purposes.
