产品介绍
脂肪酶采用黑曲霉(Aspergillus niger)优良菌种经发酵、提取精制而成,通过针对性复配,可广泛应用于皮革加工、饲料、造纸、洗涤和生物能源等行业。 原理 脂肪酶是一类能催化脂肪酸甘油酯水解,生成甘油和脂肪酸的丝氨酸水解酶,其水解反应的重要特点是在油-水界面进行。该酶也可以催化酯合成和酯交换反应。 产品特性 1.温度范围:有效温度范围30-70℃,最适温度范围在55-65℃。 2.pH值范围:有效pH范围4.0-10.0,最适pH值范围6.5-7.5。 3.金属离子对酶活性的影响:Ca2+和Mg2+对该酶有明显的促进作用,Mn2+、Fe2+和Zn2+对该酶有抑制作用,Cu2+和EDTA对酶活性影响不明显。 产品标准: 执行中华人民共和国国家标准GB/T 23535-2009。 应用方法 1.脂肪酶在面制品的应用可修补面筋网络结构中联结较弱的部分,改善面团的稳定性,提高面团持气能力,可使面包芯洁白有光泽,馒头外观白亮。推荐用量0.01-0.05kg/t面粉(酶活力以10万单位计)。该酶与食品级木聚糖酶、真菌α-淀粉酶、葡萄糖氧化酶的配合使用可综合改善面制品品质。 2.在制革工业中,该酶专一性作用于皮革中的脂肪,可在温和的条件下均匀地软化原料,在减少化学品用量的基础上增加得革率,减少皮面皱纹,使用效果明确。该酶常在脱脂、软化工序使用,加量0.02-0.06%(以原料质量计,酶活力10万单位),30-40℃下作用30-120min。该酶常与碱性蛋白酶配合使用,以优化使用效果。 3.在饲料中添加该酶可释放出短链脂肪酸,提高原料利用率,改进饲料风味,一般用量为0.01-0.05%(以原料质量计,酶活力10万单位)。 4.在造纸行业,脂肪酶可用于机械制浆和废纸脱墨的加工中。在制浆中该酶可除去纸浆中甘油三脂,在废纸脱墨中可提高脱墨效率。酶制剂添加量0.04-0.10L/t纸浆(酶活力10万单位)。 储存 本品为生物活性物质,高温、强酸、强碱会引起酶失活。因此在运输和储存过程中,液体酶应避免日光曝晒,固体酶需避免暴晒和雨淋。仓库应保持清洁、阴凉和干燥。
生化机理
Lipase which is essential for lysis of subvacuolar cytoplasm to vacuole targeted bodies and intravacuolar autophagic bodies. Involved in the lysis of intravacuolar multivesicular body (MVB) vesicles. The intravacuolar membrane disintegration by atg15 is critical to life span extension (By similarity).
