轉化糖漿

轉化糖漿是一種由葡萄糖果糖合成的黃褐色混合物,而上述兩類糖份是通過蔗糖在水中加熱而取得。[1]轉化糖漿的甜度較蔗糖高[2],且可保持較多水份及不易結晶,由於這些特質,轉化糖漿的產品在烘焙作業中備受推崇。[3]

蔗糖的分子結構是屬由兩個單醣組合而成的雙醣,通過加熱含蔗糖的溶液,使蔗糖產生水解反應,進而分解成屬於單醣的果糖和葡萄糖,這種糖漿的旋光度與普通的糖相反,所以稱爲「轉化糖漿」。上述的水解反應通常可藉著添加催化劑而加快,這些催化劑包括蔗糖酶及轉化糖苷水解酶,另使用含有果酸成份的物質如檸檬汁也可加快轉化過程。

In addition to increased moisture retention ability, converting sucrose to invert syrup has two other interesting results: increased sweetness and better solubility. On a sweetness scale where sucrose is set at 100, invert syrup ranks about 130.
