Technological aspects of obtaining melanin and powder from buckwheat hull and their use in food technology

Abstract

In the paper, technology of melanin and powder from buckwheat (Fagopyrum esculentum) hull obtaining is studied. Buckwheat hull is a by-product of buckwheat grain production and has high antioxidant activity. It is a cheap source for raw material with high content of cellulose and brown melanin pigment. In Russia, buckwheat grain is strategical crop used in child and dietary nutrition. Buckwheat hulls, which production volume is about 22% of the total volume of processed grain, are practically not used. At the same time, buckwheat hull can be regarded as a valuable raw material for obtaining of several biologically active substances and technological food ingredients due to its unique chemical composition. The possibility and prospects of using products of buckwheat hulls processing in the formulation of dessert with functional properties, is described. It was found that the implementation of buckwheat processing by-products into the desserts increases their antioxidant activity, and addition of fine powder increases dietary fiber content in them.
