摘要
采用生长周期短,易于工业化生产酵母为菌株,以糖蜜为主要培养基,通过现代发酵工程技术,在3m3发酵罐上进行中间试验,在12m3发酵罐进行试生产,发酵产品高铁营养酵母铁的含量1061mg/kg,高铁营养酵母的产率2.54%(w/v),蛋白质的含量51.90%(w/v),为工业化生产提供科学依据,并探讨作为食品添加剂的营养价值。
Yeast with fast growth rate and easy commercial process has been selected as the test strain. It used molasses as theculture medium.Through fermentation technology,both the pilot test of 3m3 fermentation tank and the process test of 12m3fermentation tank were performed. At the end of fermentation,the iron content of high-iron nutrient yeast was 1061.00mg/kg andprotein content over 51.90%(w/v).The yield of high-iron nutrient yeast was 2.54%(w/v). Scientific process parameters wereobtained.The nutrient value of high-iron nutrient used as food additive was discussed.
