Preparation and evaluation of an animal feed byproduct produced by solid-state fermentation of apple pomace.

After solid-state fermentation with different yeasts and removal of ethanol, dried apple pomace powders were found to be richer in CP (3-fold), fat (1.5- to 2.0-fold) and vitamin C (2-fold). There was also an increase in mineral content (zinc, copper, manganese and iron), crude fibre and ash. The products were free from aflatoxin. Soluble protein content increased slightly while sugar content decreased. Colour, calcium, magnesium and energy values of the dried apple pomace remained almost unaffected. Among the yeasts, Candida gave the highest CP, Saccharomyces better soluble proteins and Torula the lowest fat content with comparable total sugar but different acid contents. Yield of dried apple pomace varied from 54 to 65% with dehydration (4.35:1) and rehydration ratios (1:40.20 to 1:4.60) quite comparable to the dried, unfermented apple pomace. It is concluded that apple pomace used concomitantly for ethanol production by fermentation with Saccharomyces and dried after ethanol removal could be

used profitably as an animal feed.
