污染黄曲霉毒素B_1(简称AFTB_1)的花生麸,经7～30%生石灰粉作实验室去毒试验,去毒率为60%～90.5%。在大田试验中,用20%石灰粉去毒,抽检6次,平均去毒率为93.7%;用30%生石灰粉去毒,平均去毒率为95.8%。但值得注意的是,凡用石灰去毒的花生麸,其粗旦自有所降低,给去毒的花生麸与麦麸混合(1+2),作日根喂猪(5只猪), 任其自由采食,共喂饲63天,食入花生麸40公斤,后扑杀,未发现肉眼可见的异常病变。而未经去毒的含AFTB_148000ppb的花生麸对照组(4只猪),共喂饲4公斤花生麸,试验猪在12、24、27和37天相继死亡,并出现典型的AFTB_1中毒症状。
Pollution aflatoxin B_1 (AFTB_1) of peanut bran, 7 ~ 30% lime powder for laboratory detoxification test, detoxification rate of 60% to 90.5%. In the field trials, detoxification with 20% lime powder, sampling six times, the average detoxification rate of 93.7%; with 30% lime powder detoxification, the average detoxification rate of 95.8%. It is noteworthy, however, that peanut bran detoxified with lime has its own reduced crude denier, mixed detoxified peanut bran and wheat bran (1 + 2), pigs (5 pigs) Free to feed their own, a total of 63 days feeding, eating peanut bran 40 kg, after the culling, found no abnormal lesions visible. The untreated AFTB_148000ppb peanut bran control group (4 pigs) was fed 4 kg of peanut bran. The pigs died one after the other on days 12, 24, 27 and 37 with the typical symptoms of AFTB_1 poisoning.
