摘  要:
为研究糖-酶解液模型体系中5-羟甲基糠醛的形成动力学规律,以2种糖(葡萄糖和蔗糖)和3种肉(猪、牛、鸡肉)酶解液为研究对象,通过高效液相色谱分析研究了糖-酶解液模型体系中5-羟甲基糠醛的形成动力学模型。结果显示:加热温度90~110℃、加热时间0~6 h条件下,5-羟甲基糠醛的生成量与加热时间呈线性关系,符合零级动力学模型;5-羟甲基糠醛的生成量与加热时间、加热温度呈正相关,随着加热温度的升高、加热时间的延长,糖-酶解液模型体系中5-羟甲基糠醛含量呈持续增长的趋势,并且在葡萄糖-酶解液体系中5-羟甲基糠醛的含量远远高于蔗糖-酶解液体系。

摘  要:
The formation kinetics of 5-hydroxymethylfurfural(5-HMF) was investigated in model Maillard reaction systems consisting of two sugars(glucose and sucrose) and enzymatic protein hydrolysates from pork, beef and chicken. The 5-HMF content of the Maillard reaction products(MRPs) was determined by high performance liquid chromatography(HPLC). Results indicated that 5-HMF content was linearly correlated with heating time during thermal processing at 90–110 ℃ for 0–6 h. The formation of 5-HMF followed zero-order kinetics. 5-HMF content was positively correlated with heating time and temperature. The concentration of 5-HMF formed in the glucose-protein hydrolysate systems was much higher than that formed in the sucrose-protein hydrolysate systems.
