产品介绍
无花果蛋白酶(Ficin)被归类为硫醇蛋白酶。由无花果 (Ficus sp.)树的胶乳和不成熟的果实乳汁用pH值4.0的水进行抽提,在乙二胺四乙酸(EDTA)存在下用硫酸铵进行盐析(二次),再用食盐盐析二次而成。得率约11%。一个绿的重10~15g的无花果,可含有100~150mg商业性无花果蛋白酶。经阳光干燥后仅存活力约12%,100℃烘干的果实已无活性。 使用效果: 1.降低麦汁粘度和浊度,提高过滤速度。 2.水解纤维素、半纤维素,破碎大麦细胞壁,充分释放胞内物质,提高麦汁得率。 3.加强蛋白质的分解转化,增加氨基酸含量。 4.阻断部分双乙酰生成途径,减少酒中双乙酰含量,缩短发酵时间,提高酒品质量。 5.用于发酵时,有助清酒过滤,提高酒品的非生物稳定性,延长保质期。 在PH值7.0、温度37±0.2℃条件下,每分钟水解酪蛋白释出的可溶物在275nm波长吸光度与1微克酪氨酸的吸光度相当时,所需的酶量即为一个活力单位,用u表示。 产品应用: 无花果蛋白酶为酶制剂。无花果蛋白酶用于啤酒抗寒(水解啤酒中的蛋白质,避免冷藏后引起的浑浊);肉类软化(水解肌肉蛋白质和胶原蛋白,使肉类嫩化);焙烤时的面团调节剂;干酪制造时的乳液凝固剂(代替凝乳酶)。
