摘要
[目的]提高沙棘果渣的蛋白质含量。[方法]以沙棘果渣为原料,采用酿酒酵母和产朊假丝酵母发酵生产蛋白饲料,利用正交试验确定了无机盐的用量及发酵工艺条件。[结果]当酿酒酵母:产朊假丝酵母为1∶6,添加3%硫酸铵、0.2%磷酸二氢钾及0.05%硫酸镁,原料含水率65%,接种量10%,初始pH 6.0,30℃发酵48 h,得到的产品经烘干、粉碎后测得粗蛋白含量23.5%,且具有浓烈的醇香味。[结论]该研究为沙棘果渣饲料化的高效利用提供了参考依据。
[ Objective ] To improve the protein content in sea buckthorn. [ Method] The marc of sea buckthorn was fermented by Saccharomy- ces cerevisiae and Candida utilis to prepare protein feeds. The conditions of fermentation and amount of inorganic salt were determined by using orthogonal design. [ Result] When the ratio of Saccharomyces cerevisiae to Candida utilis was 1：6, 3.0% ammonium sulfate, 0.2% potassium dihydrogen phosphate and 0.05% magnesium sulfate were, added, the initial pH was 6.0 and the inoculation volume was 10% with 30 ℃ cul- tivate temperature and 48 h fermentation duration, the crude protein in product was 23.5% with specific alcohol aroma. [ Conclusion ] The study provides references for the high-efficient utilization of sea buckthorn marc feeds.
