鲍鱼蒸煮液美拉德反应制备海鲜调味基料工艺优化

为研制新型的海鲜调味品基料，以鲍鱼蒸煮液为原料，加入木糖进行美拉德反应，对样品进行感官评定及pH值测定，同时辅以电子鼻分析美拉德产物的气味变化，研究不同木糖添加量、反应温度及反应时间对美拉德反应程度及产物的影响，确定鲍鱼蒸煮液美拉德反应的制备工艺。结果表明，不同反应条件对反应程度及产物气味组成均有影响，正交试验得出鲍鱼蒸煮液美拉德反应工艺的最优参数为木糖添加量10%、反应温度110 ℃、反应时间40 min，此条件下产物的pH值为4.73±0.08，A280 nm为0.37±0.02，A420 nm为0.27±0.02。

Optimization of Preparation of Seafood Flavor Condiment Base from Cooked Abalone Juice by Maillard Reaction

In this study, cooked abalone juice was used to produce seafood flavor condiment base via Maillard reaction with xylose under heating conditions. Sensory evaluation and pH value of the reaction products were determined and odor changes were analyzed using electronic nose. Using orthogonal array design, the reaction conditions xylose concentration, temperature and time were optimized to be 10%, 110 ℃, and 40 min, respectively. Under the optimized conditions, the pH value of the Maillard reaction products was 4.73 ± 0.08, and absorbance values at 280 and 420 nm (A280 nm and A420 nm) were 0.37 ± 0.02, and 0.27 ± 0.02, respectively.
