    摘要:

    利用葡萄糖對大豆7s球蛋白進(jìn)行濕法糖基化處理,制備出大豆7s球蛋白3種糖基化產(chǎn)物。通過旋轉(zhuǎn)流變儀、質(zhì)構(gòu)儀和掃描電鏡對大豆7s球蛋白及其3種糖基化產(chǎn)物凝膠的流變性、質(zhì)構(gòu)性及微觀結(jié)構(gòu)進(jìn)行分析,研究糖基化反應(yīng)對大豆7s球蛋白熱致凝膠性的影響。結(jié)果顯示:糖基化反應(yīng)提高了大豆7s球蛋白的熱穩(wěn)定性,提前了大豆7s球蛋白的凝膠點(diǎn),增加了大豆7s球蛋白凝膠的粘彈性,說明糖鏈的接入促進(jìn)了大豆7s球蛋白凝膠網(wǎng)絡(luò)的形成。

    Abstract:

    Glucose was used as an agent to modify soybean 7s globulin, in order to prepare for three glycation products of soybean 7s globulin. Rotary rheometer, texture analyzer and scanning electron microscope were used to analyze rheology, texture and microstructure of soybean 7s globulin and its glycosylation product gel, in order to study the effect of glycosylation reaction on 7s globulin gel. Research results showed that glycosylation reaction could improve the thermal stability of soybean 7s globulin and move up the soybean 7s globulin gel point. The viscoelasticity of the soybean 7s globulin gel was increased. The sugar chains could promote the formation of the soybean 7s globulin gel network.
