Character:
類白色至微帶黃色的粉末,微臭,但無霉敗的臭氣;有引濕性,是以胰蛋白酶、胰淀粉酶、胰脂肪酶為主所組成的多種酶的混合物,水溶液煮沸或遇酸即失去酶活力。本品在中性或弱堿性環(huán)境中(酸堿度6.8~8.5)可促進(jìn)蛋白質(zhì)、淀粉及脂肪的消化。有吸濕性。溶于水呈微渾溶液,不溶于乙醇和乙醚。
Quality Standard:
性狀 Appearance 白色或微黃色粉末
鑒別 A、B 符合規(guī)定
脂肪fat ≤4.5%
干燥失重Loss on drying ≤4.5%(真空0.7Kpa 60℃ 4h)
有機(jī)溶劑殘留 <0.5%
酶活力enzyme activity:
胰蛋白酶protease activity 1.0~5.2 Ph.Eur.U/mg
胰淀粉酶amylase activity 20~65 Ph.Eur.U/mg
胰脂肪酶lipase activity 25~110 Ph.Eur.U/mg
來源
胰酶是采用特有的激活提取技術(shù)從豬胰臟中分離提取的.
Storage:
儲存溫度 ?20°C避光保存
用途 酶反應(yīng):能轉(zhuǎn)化不少于25倍量的酪蛋白成為 (在5分鐘內(nèi),相當(dāng)于在30分鐘內(nèi)150倍)。其最大活力在中性或微堿性介質(zhì)中。礦酸或過量氫氧化物或碳酸鹽使之失活。
