Potato protein enriched

Other examples in which the whole product is used include the production of animal feeds by the protein enrichment of sweet potato residue, cassava peel, or whole cassava, or when SSF is used to remove toxic or inhibitory compoimds from feed materials, such as the reduction of phytic acid in canola meal, antidigestive constituents in rye, or caffeine from coffee pulp [187-193]. In these studies it was not made clear whether the product would be used fresh or dried. This is because the research addressed the feasibility of the process itself, and not the use of the product as food or feed. The major consideration as to whether the product will be dried is the time the product must be kept before use, and the perishability of the product... 

It is used as organic fertilizer, as cattle feed, as substrate for fungi cultivation, or for microbial enzyme production. Further uses are proposed in lactic acid fermentation and adhesives production. The potato fruit liquid by-product is used for protein enrichment and as fertilizer [22, 23]. 

Supplementing chick diets with a protein fraction, isolated from raw Russet Burbank potato tubers, enriched in proteinase inhibitors, had previously been shown to severely depress their growth (5). The inhibitor-rich fraction contained at least six well characterized inhibitors of mammalian pancreatic digestive proteinases trypsin, chymotrypsin, elastase and carboxypeptidases A and B (5). Since the fraction contained an array of proteinase inhibitors it was not known if CPI contributed to the growth depressing activities.
