各位好
來講一下蝦仁成分裡面的成分
然後我看推文也有提到脆度的問題
所以來解密一下原理
蝦子蛋白質的等電點(PI值,Isoelectric Point是pH4.9~5.4左右)
所以如果酸鹼值到這個區間
蛋白質會無法抓住水,就會沈澱
就會沒彈性、吃起來粉粉的
而且沒辦法抓住水,調味入味也會有問題
所以可以看到廠商或者廚師,會讓肉的酸鹼值偏離等電點
不論是利用酸,像是加檸檬汁
或者是這篇的廠商利用碳酸鈉讓食品往鹼性那邊
離開等電點的區間
所以看食品的成分標示可以看出很多事情
有些人喜歡吃脆,有些人喜歡吃粉,就看人口味了
另外雞肉、豬肉等肉類,都是蛋白質,都有這種特性
以上謝謝
希望對各位有所幫助
