Chloroform-methanol extracts of lyophilized milk, of commercially available dried milk or baby food and of casein digests were tested for opioid activity on the guinea-pig ileum longitudinal muscle-myenteric plexus preparation. Compounds with opioid activity--which proved to be resistant to peptidases--were detected in certain batches of baby food, casein digest, and cow milk in considerably varying amounts.
对冻干牛奶、市售奶粉或婴儿食品以及酪蛋白消化物的氯仿 - 甲醇提取物进行了测试，以检测其对豚鼠回肠纵肌 - 肠肌丛标本的阿片样物质活性。在某些批次的婴儿食品、酪蛋白消化物和牛奶中检测到了具有阿片样物质活性的化合物——这些化合物被证明对肽酶具有抗性，且含量差异很大。
