Animal feed, potato application

The cereal seeds, tubers, starch storage roots, and bean/pea seeds are directly consumed as food in human diet or animal feed and are used as a source of starch. Extracted starch can be used to produce starch derivates or hydrolyzed to produce soluble sugars, food additives, or glucose syrup. Also, extracted starch can be used for other applications in nonfood industries (Nghiem et al. 2011). For example, it is used as a thickener and as a source of renewable raw material for bioethanol production. The major source of starch for the world market is cornstarch holding more than 80 % of the market, but wheat, potato, cassava or tapioca, and to a lesser extent rice and sweet potato starches are also commercialized (Thomsen et al. 2008). 

P. are important in all physiological functions and for nutrition. Plants are able to produce p. to satisfy their own demands. Animals need supplementary amino acids. Sources of p. for food and feed as well as technical applications are meat, ->fish, soybean, gluten (->gluten cereal), ->potato p., pea (->pea starches).
