New technological approach of integrated wheat grain processing
2001
Pavkov-Avramovic, A.M.
This M.Sc. thesis presents an integral wheat processing procedure comprising of three different processes: milling (dry/mechanical), starch technology (wet/chemical) and fermentation (biochemical) with defined final value added products (high quality white flour, wheat gluten, ethanol and high-valued by-product - stillage). During applied integrated wheat processing, after milling of six selected Yugoslav varieties, eight flours with over 0.5% (dm) ash content, have been separated. These flours represent the samples of combined flours which underwent through two different and successive types of procedure: starch dough extraction (separation starch/gluten), and fermentation of starch substrate into ethanol. Obtained results show that all varieties have satisfactory potential for starch processing and extractability, and the yield and recovery of ethanol indicate that, for the majority of wheat varieties, starch fraction is adequate fermentation substrate for the ethanol production.
