研究不同燕麦全粉添加量对燕麦—小麦混合粉的面筋和面团特性的影响,进一步通过添加谷氨酰胺转氨酶(TGase)与不同外源蛋白质(花生蛋白或谷朊粉)来改善混合粉的品质,并研究不同添加剂对混合粉蛋白质组成的影响。结果表明:随着燕麦全粉添加量的增加,燕麦—小麦混合粉的湿面筋含量、面筋指数、沉降值和面团稳定时间都呈现显著减少的趋势,而面团吸水率逐渐增大。对于燕麦全粉添加量为30%的燕麦—小麦混合粉,当 TGase 添加量达到或超过0.8%(w/w)时,面团的形成时间和稳定时间均显著增加。向混合粉中同时添加 TGase 和花生蛋白可显著增加 SDS不可溶性谷蛋白的含量,进一步延长面团稳定时间。
研究不同燕麥全粉添加量對燕麥—小麥混閤粉的麵觔和麵糰特性的影響,進一步通過添加穀氨酰胺轉氨酶(TGase)與不同外源蛋白質(花生蛋白或穀朊粉)來改善混閤粉的品質,併研究不同添加劑對混閤粉蛋白質組成的影響。結果錶明:隨著燕麥全粉添加量的增加,燕麥—小麥混閤粉的濕麵觔含量、麵觔指數、沉降值和麵糰穩定時間都呈現顯著減少的趨勢,而麵糰吸水率逐漸增大。對于燕麥全粉添加量為30%的燕麥—小麥混閤粉,噹 TGase 添加量達到或超過0.8%(w/w)時,麵糰的形成時間和穩定時間均顯著增加。嚮混閤粉中同時添加 TGase 和花生蛋白可顯著增加 SDS不可溶性穀蛋白的含量,進一步延長麵糰穩定時間。

The effect of addition amount of oat flour on the gluten and dough properties of oat -wheat mixed flour was investigated.The qualities of oat -wheat mixed flour were improved by addition of trans-glutaminase and exogenous proteins (peanut protein and gluten)and the protein composition of resulted mixed flour was also analyzed.The results showed that with the increase of oat flour content,the wet -gluten,gluten index,sedimentation value and stability time of oat -wheat mixed flour were significantly decreased and the water absorption was enhanced.In case of the mixed flour containing 30% oat powder, as the addition amount of transglutaminase was 0.8% (w/w)or more both dough development time and stability time were significantly increased.When transglutaminase and peanut protein were added into mixed flour at the same time,the relative content of SDS insoluble glutenin and dough stability time were further increased.
