摘要
用水体系对菜籽粕进行脱毒,考察硫酸体积分数、料液比、脱毒时间、脱毒温度、脱毒次数等对菜籽粕脱毒效果的影响,以单宁脱除率为评价指标。结果表明,影响单宁提取效果的因素顺序为脱毒温度>料液比>脱毒时间,最佳工艺条件为:以水为脱毒溶剂,料液比为1∶20 g/m L,脱毒温度90℃,振荡浸提90 min,脱毒2次。在此条件下,菜籽粕中单宁、植酸、硫甙的脱除率分别为68.21%,71.03%,72.46%,符合饲料级要求,能适量取代鱼粉或豆粕用于饲料。
The technique parameters of detoxification from rapeseed meal were performed using the system of water. The effects of sulfuric concentration, solid-liquid ratio, temperature, time and times on the detoxification of tannin from rapeseed meal were studied. Tannin removal rate as evaluation index. The results showed that the influencing order for detoxification of tannin were as follows：temperature 〉 solid-liquid ratio 〉 time. The optimum conditions were ： the ratio of liquid to solid 1 ： 20 g/mL, 90 ℃ extraction for 90 rain, detoxification two times. The removal rate of tannin ,phytic acid and glucosinolate were 68.21%, 71.03% and 72.46%. After detoxifieation, the rapeseed meal could meet the feed requirement and replace soybean meal or fish meal in formula feed. Key words： rapeseed meal; detoxification ; water system ; tannin
