By-products of black (Brassica Nigra) and white (Sinapis Alba) mustard seed production as animal feed: Possibilities and hazards

Abstract

The agri-food industry generates thousands of tons of by-products such as skins, peels, seeds, leaves and other inedible fractions. Such by-products usually cause environmental issues due to their large amounts and high water activity promoting microbial development. Food by-products can be readily recycled and utilized as a source of fuel, feed and fertilizer. Therefore, it seems logical and feasible to turn food by-products into animal feeds. The purpose of this study is to produce a new animal feed compound by extruding by-products of black and white mustard seeds production. After extrusion, the feed compound obtained was dried and stored in two manners: under ambient conditions and in a climate chamber under accelerated conditions of high temperature and air humidity. Our objective was to examine the oxidative stability of the feed compound produced, and to compare the properties of black and white mustard seed extrudates.
