蒸汽爆破参数对菜籽粕中总硫苷脱毒效果的影响
A Study of Steam Explosion Parameters on Detoxification Effect of Total Glucosinalates in Rapeseed Meal
摘要
Abstract
This experiment was conducted to study the steam explosion parameters, such as water material ratio, retention time and or steam pressure, on detoxification effect of total glucosinolates in rapeseed meal, and evaluates the nutrient digestibility in vitro using a computer-controlled simulated digestion system.The singlefactor experiments were designed for choosing the optimal water material ratio, the optimal retention time and the optimal steam pressure.Each experiment was divided into 4 levels, with 3 repetitions in each level.The results showed that steam explosion treatment can affect the total glucosinolates detoxification effect in rapeseed meal, the detoxification percentage of total glucosinalates ranged from 73.71％ to 86.98％.The optimal water material ratio was 25％, the optimal retention time was 60 s, and the steam pressure was 2.0 MPa for the detoxification percentage of total glucosinalates when designed as single-factor experiments.As nutrient digestibility in rapeseed was considered, compared with the untreated group, steam explosion of 1.0 and 1.5 MPa(fixed water material ratio at 25％, and retention time at 60 s) had no significant influences on nutrient digestibility in vitro in rapeseed meal (P>0.05), but 2.0 MPa steam explosion could significantly reduce the digestibility of crude protein, lysine and arginine (P<0.05), steam explosion could significantly increase the content of total glucosinalates and isothiocyanate (P<0.05).In conclusion, comprehensive consideration of total glucosinolates detoxification percentage and nutrient digestibility, the appropriate steam pressure should be not greater than 2.0 MPa as fixed water material ratio at 25％, retention time at 60 s.[Chinese Journal of Animal关键词
