2025 biology talkshow: Q彈水膠的食品科學奧秘

from 雷比特生物空中講 · host 雷比特老師

介紹日常生活中常見的幾種水膠(Hydrocolloid)及其科學原理,將它們定義為介於固體與液體之間、能束縛大量水分的高分子聚合物結構。文章透過對比吉利丁(動物膠原蛋白水解物)、洋菜(紅藻多醣)、藻膠(褐藻多醣)與愛玉(台灣特有植物果膠)等四種主要成員,解釋它們各自不同的來源、化學本質與凝膠機制。例如,吉利丁是熱致可逆的蛋白質凝膠,洋菜則需要高溫溶解、形成脆性凝膠,而藻膠和愛玉則主要依賴鈣離子進行非溫度依賴性的交聯作用。此外,也簡要提及仙草的凝膠特性,並總結這些分子是如何透過不同路徑達到「鎖水」效果,展現分子生物化學的應用。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/07bd60205c53 Powered by Firstory Hosting
