Title: A Preliminary Study on Walnut Cake Microbial Fermented Feed
Abstract: As a new type of protein feed,microbial fermented feed became a research hot spot.The pressed walnut cake was used as the main raw material and mixed with corn flour to be inoculated with yeast for solid state fermentation,aiming at studying the change of crude protein content in the fermentation product in order to obtain new microbial fermented feed with high protein content.Considering crude protein content as the indicator,the optimal fermentation conditions were determined by single factor experiment and orthogonal experiment.The results showed that the optimal fermentation conditions were as follows: corn flour and walnut cake ratio of 2 ∶1,inoculum concentration of 10%,fermentation time of four days and fermentation temperature of 30 ℃.Under such conditions,the crude protein content in the feed by fermentation was 34.26%.Compared with unfermented corn flour with crude protein content of 10.78%,it was improved by 23.48%.The conclusion not only contributed to the development and utilization of walnut cake but also provided the foundation and basis for the study of production of high-protein feed by fermentation plant protein.
