| 摘 要： | 以嗜热链球菌(Streptococus thermophilus)、保加利亚乳杆菌(Lactobacillus bulgaricus)和瑞士乳杆菌(L.helveticus)及2种酿酒酵母菌(Saccharomyces cerevisiae)为菌种,对罗非鱼(Oreochromis niloticus)下脚料蛋白酶解液进行发酵,利用感官评定法,比较不同微生物发酵对酶解液脱腥去苦效果.试验结果表明,乳酸菌脱腥效果优于酵母菌,其中以嗜热链球菌脱腥效果最好,其适宜的发酵条件为接种量10%,发酵温度42℃,发酵时间9 h.微生物发酵去苦效果不明显.

| Abstract: | This work is to compare the effects of removing fish odour and bitter in protein hydrolysates of tilapia Oreochromis niloticus wastes by different microorganisms fermentations,in which lactic acid bacteria such as Streptococus thermophilus,Lactobacillus helveticus,L.bulgaricus and yeasts were used. The removal potency of fish odour and bitter was evaluated by sensory test. The results indicated that the effect of fish odour removal from protein hydrolysates by lactic acid bacteria fermentation was better th... |
