摘要
本课题以天然的猪肉酶解液为主要原料,通过酶解与关拉德反应制备一种肉味膏状香精,确定制备膏状肉味香精的最佳工艺,并对其稳定性进行检测。以不同反应物配比、反应温度和反应时间对香精感官评价的影响为指标,通过单因素实验和正交实验得到肉香基的最佳物料配比为葡萄糖2.5%,蛋氨酸1.5%,L-半胱氨酸盐酸盐水合物1.0%;最佳工艺条件为反应时间90min,反应温度103℃。放置一周后没有发现明显分层现象和浮油出现,离心后香气也无明显变化,香精稳定性较好。
This subject mainly studied the preparation of a meat paste flavour through Maillard reaction with quality of natural pork enzymatic hydrolyzate as raw materials,and tested its' stability.With different ratio of reactants,reaction temperature and reaction time on the essence of the influence of sensory evaluation as an index,the orthogonal experiments and single factor experiments indicated the best materials ratios of the meat-base is glucose 2.5%,methionine 1.5%,L-homocysteine hydrochloride hydrate 1.0%,the best reaction time is 90 min and the best reaction temperature is 103℃.A week later,we found no obvious stratification and oil slick.After centrifugation,the fragrance is also no obvious change,these indicate paste flavour has a preferable stability.
