Mechanical fractionation and storage of flaxseed

摘要: Recently, flaxseed has gained recognition as a food ingredient due to potential health benefits associated with flaxseed consumption. The hull is rich in fiber and the lignan, secoisolariciresinol diglucoside (SDG); and the embryo contains oil high in alpha-linolenic acid, an omega-3 fatty acid.Previous bench-scale trials demonstrated that an abrasive method of dehulling flaxseed gave favorable results. Our objectives in recent studies were 1) to increase the yield and purity of hull and embryo fractions and also process capacity, and 2) to examine storage effects on the fractions produced.
