The method for extraction, and quantitative determination of phenolic acids in rapeseed flour was investigated. In examined- rapeseed flour (var. Tower), the following phenolic acids were identified: salicylic, p-hydroxybenzoic, p-coumaric, ferulic, sinapic and z-sinapic. Among the identified phenolic acids, sinapic acid was dominated.
The efficiencies of protein and starch recoveries by pin milling and air classification of field peas exceeded those obtained by wet processing which exhibited 30% losses of dry matter in the effluent. Pin milling reduced amylograph viscosity whereas refined starch exhibited high viscosity during the heating and cooling cycle. Wet processed proteinates showed high water hydration and oil absorption capacities whereas the air classified protein fraction was superior in whipping and foam stability.
