New developments in the field of protein enrichment of foods and feeds (P.E.F.F)

Abstract

AbstractUp to the year 2000 the total demand of protein for animal feeding will rise by 146%. This demand can not be covered by agriculture alone. According to FAO data it will be an expected deficit of some 400 million tons of cereals at this time all over the world. Therefore the large scale industrial production of SCP from alkanes, methanol and other raw materials will undoubtely become soon an absolute necessity. On the other hand, a new process of solid state fermentation (ORSTOM/IRCHA process) having special interest for the developing countries has been recently set‐up in France.Based on dried and crushed potatoes or cassava (manioc or tapioca) protein enrichment by fermentation of feeds of foods (PEFF) in a simple manner without aseptic conditions with the filamentous fungus Aspergillus hennebergii is carried out. The process is presently optimized and scaled‐up to the size of a 700 kg (dry weight) fermenter.Nutrititional and toxicological assays have demonstrated complete safety and excellent nutrititional value of the product, which is applicable as a feedstuff for breading of e.g. pigs or chickens.
