【摘要】：为了探讨电子束辐照对饼粕类饲料中抗营养因子的抑制作用,以1、2、3、5、7、9 k Gy剂量的电子束对豆粕、菜籽粕、棉籽粕等饲料进行辐照处理,研究辐照对大豆抗原、硫葡糖苷及其水解产物、植酸、单宁及游离棉酚的影响。结果表明,电子束辐照可有效降低饼粕类饲料中大豆球蛋白、硫代葡萄糖苷及其水解产物、植酸、单宁、游离棉酚等的含量,其中3 k Gy电子束辐照后,大豆球蛋白降低22.63%;7 k Gy下异硫氰酸酯降低17.17%,9 k Gy下VA唑烷硫酮、硫代葡萄糖苷、单宁、游离棉酚分别下降14.17%、15.83%、18.18%、13.17%,但电子束辐照对β-伴大豆球蛋白和胰蛋白酶抑制因子的抑制效果不显著。本研究结果为饼粕类饲料中抗营养因子的消除提供了理论参考。
[Abstract]:In order to investigate the effect of electron beam irradiation on the inhibition of anti-nutrition factors in meal feed, soybean meal, rapeseed meal and cottonseed meal were irradiated with electron beam at a dose of 1 ~ 2 ~ 2 ~ 3 ~ 3 ~ 3 ~ 5 ~ 5 ~ 5 ~ 7 ~ (9) Gy to study the effects of electron beam irradiation on soybean antigen. Effects of glucoside and its hydrolysates phytic acid tannin and free gossypol. The results showed that electron beam irradiation could effectively reduce the contents of soybean globulin, thioglycoside and its hydrolysates, phytic acid, tannin and free gossypol in the feed of cake meal. Soybean globulin decreased 22.63; The decrease of isothiocyanates at 7 k Gy was 17.17 k / Gy, including the decrease of VA azolidone, thioglycoside, tannin and free gossypol at 17.17 k / Gy, respectively. However, the inhibitory effect of electron beam irradiation on 尾-concomitant soybean globulin and trypsin inhibitor was not significant. The results of this study provide a theoretical reference for the elimination of anti-nutritional factors in meal feed.
