大豆抗原蛋白Glycinin及其对鱼类健康的影响
Glycinin 免疫原性 抗营养作用 鱼类
2015/10/14
大豆抗原蛋白既是大豆的主要营养成分,又是大豆抗营养因子的主要种类之一,是限制大豆蛋白源在食品及饲料行业广泛应用的关键因素。其中,大豆球蛋白(Glycinin)和β-伴大豆球蛋白(β-Conglycinin)是免疫原性最强的大豆蛋白。Glycinin具有较强的热稳定性,普通的热处理对其免疫原性的灭活能力较小。Glycinin在鱼类饲料中含量过高,会引起鱼类肠道损伤,消化酶活力降低,生长缓慢,甚至死亡...
Emulsifying Properties of a Peptide from Peptic Hydrolysates of Soy Glycinin
glycinin pepsin peptide emulsifying activity
2009/6/10
Soy glycinin was hydrolyzed by pepsin under controlled conditions. The emulsifying activity of the hydrolysates was found to be higher than that of glycinin. Fractionation of the peptides was performe...
