Abstract
一种牡蛎肽制备方法包括如下制备步骤:(1)将牡蛎洗净,加入牡蛎重量7~10倍水,再加入牡蛎重量0.03~0.08%的无花果蛋白酶,调节pH值至4.7~4.9,升温至51~54℃,酶解10~20min,取牡蛎肉;(2)将牡蛎肉打碎,加入其重量2~4倍水,搅拌均匀,得到牡蛎浆液;(3)再加入牡蛎肉重量0.04~0.09%的复合酶,调节pH至5.3~6.5,升高温度至46~52℃,均质100~140min,灭酶,得到酶解液;(4)将酶解液进行超滤,冷冻干燥,得到牡蛎小分子肽。本发明的牡蛎肽制备工艺简单,生成周期短,所生产的牡蛎肽产品无腥味、口感好,所含的混合肽分子量小,可作为蛋白营养补充剂直接食用。
Description
技术领域
本发明属于生物工程领域,具体的说是一种用复合酶水解牡蛎蛋白制备小分子肽的方法。
背景技术
牡蛎多肽不仅含有丰富的蛋白质,且含有维生素,比例合适的微量元素和牛磺酸,而且还含有海洋生物所特有的多种营养成分,其中天然牛磺酸,在医疗上确认具有降血脂、抑制血小板聚集,改善高血糖症状,提高人体免疫力,促进新陈代谢等功能。因此,在动脉硬化、冠心病、心绞痛、高血脂、心率不齐、糖尿病、慢性肝炎以及免疫力下降等疾病治疗中,都有较好的疗效。同时,牡蛎对抗癌和防止癌细胞扩散也有一定效果。
目前,从牡蛎壳中制取牡蛎肽的方法主要有酸解法和酶解法,酸解法反应剧烈,反应过程及最终产物难于控制,会造成大量氨基酸的破坏,用牡蛎粉直接酶解,难度大、时间长、不易过滤,获肽率低。
发明内容
本发明为了弥补现有技术得不足,提供了一种工艺简单、生产周期短的复合酶水解牡蛎蛋白制备小分子肽的方法。其步骤如下:
一种用复合酶水解牡蛎蛋白制备小分子肽的方法,其特征在于,包括如下制备步骤:
(1)将牡蛎洗净,加入牡蛎重量7~10倍水,再加入牡蛎重量0.03~0.08%的无花果蛋白酶,调节pH值至4.7~4.9,升温至51~54℃,酶解10~20min,取牡蛎肉;
(2)将牡蛎肉打碎,加入其重量2~4倍水,搅拌均匀,得到牡蛎浆液;
(3)再加入牡蛎肉重量0.04~0.09%的复合酶,调节pH至5.3~6.5,升高温度至46~52℃,均质100~140min,灭酶,得到酶解液;
(4)将酶解液进行超滤,冷冻干燥,得到牡蛎小分子肽。
本发明的牡蛎肽制备工艺简单,生成周期短,所生产的牡蛎肽产品无腥味、口感好,所含的混合肽分子量小,可作为蛋白营养补充剂直接食用。也可作为临床营养品、保健品、运动食品以及其他功能配料提高牡蛎产品的高价值。
具体实施方式
根据本发明内容所述的方法,进一步提供本发明的实施例。
本发明实施例提供一种牡蛎肽的制备方法,其步骤如下:
(1)将牡蛎洗净,加入牡蛎重量7~10倍水,再加入牡蛎重量0.03~0.08%的无花果蛋白酶,调节pH值至4.7~4.9,升温至51~54℃,酶解10~20min,取牡蛎肉;
(2)将牡蛎肉打碎,加入其重量2~4倍水,搅拌均匀,得到牡蛎浆液;
(3)再加入牡蛎肉重量0.04~0.09%的复合酶,调节pH至5.3~6.5,升高温度至46~52℃,均质100~140min,灭酶,得到酶解液;
(4)将酶解液进行超滤,冷冻干燥,得到牡蛎小分子肽。
