大豆饼粕提取干酪素技术内容摘要:
最新农副产品和食品加工技术大豆饼粕提取干酪素技术干酪素是一种优质的食品。 同时也是一种用途广泛的化工原料:是塑料皮革和油漆皮革和油漆等工业中的上光剂,是造纸工业的用胶料以及木材工业的粘结剂。 现介绍利用大豆饼粕提取干酪素的方法如下:1 溶解称取一份冷榨大豆饼,配以 度氢氧化钠溶液置于容器中加热,加热至 4850并不断搅拌,大约经 3 小时(加热升温时间除外),使蛋白质充分溶出。 2 过滤溶解后,用离心机分出液相,再用较疏的细布将滤液过滤 23 次。 3 沉淀当溶解液冷却到 3035以下时,除尽表面碱不溶性薄膜,将稀盐酸液徐徐加入蛋白质溶液中,调 置 34 小时使其完全沉淀。 4 漂洗用虹吸法吸去沉淀物上层之清水,再加入清水搅匀沉淀后去除水,如此反复45 次,使 保持在 5燥把漂洗后的沉淀物用离心机离心去水,置于 50的烘房中低温干燥或日光晒干即可。 6 墨粉、包装用磨粉机将干燥后的干酪素粗制品制成细粉,过筛即为成品干酪素。 包装时用纸袋、布袋或木桶均可,但要注意密封防止潮湿。 专利查询。大豆饼粕提取干酪素技术
