摘要:

研究超高压对风味蛋白酶处理大豆分离蛋白(soybean protein isolate,SPI)中致敏原P34免疫活性的影响。并对脱敏后的SPI功能特性进行了研究。结果表明:超高压处理对风味蛋白酶消除SPI中致敏原P34具有促进作用,将消除P34致敏性的酶解时间由120 min缩短到了60 min。超高压联合风味蛋白酶酶解脱敏的SPI溶解性、黏度、保水性、吸油性、乳化性和乳化稳定性、起泡性和泡沫稳定性都比单纯酶酶解的SPI明显提高。

Abstract:

The effect of ultra-high pressure (UHP) combined with enzymatic hydrolysis on the allergenicity of P34 in
soybean protein isolate (SPI) and the functional properties of desensitized SPI was studied. The results showed that ultra-high
pressure could accelerate the hydrolysis process to eliminate the immune activity of soybean protein P34 using flavourzyme
and improve the hydrolysis efficiency by 50%. The solubility, viscosity, emulsification, water-holding capacity, oil-absorbing
capacity, emulsion stability, foaming capacity and foam stability of SPI subjected to the combined treatment of ultra-high
pressure and hydrolysis were improved obviously when compared with the latter alone.

Key words: soybean, allergenic protein, P34, ultra-high pressure, hydrolysis
