Study on Processing Technology of Actinidia arguta Enzyme Suck Jelly
-
摘要: 以软枣猕猴桃为原料,经发酵、调配制作软枣猕猴桃酵素可吸果冻,在单因素试验基础上,采用正交试验对工艺进行优化,通过感官品质评价确定软枣猕猴桃酵素果冻配方,通过测定总酚、类黄酮和VC指标,对本产品与市售猕猴桃可吸果冻、果汁的营养物质含量进行比较。结果表明,软枣猕猴桃酵素果冻的最佳工艺配方为:软枣猕猴桃酵素添加量35%,白砂糖添加量5%,柠檬酸添加量0.06%,卡拉胶添加量0.8%。由该配方制作的可吸果冻入口细腻、酸甜适口,具有软枣猕猴桃独特果香,且营养物质(总酚、类黄酮、VC)含量均显著高于市售产品。综上所述,该产品是一款风味独特、具有保健功能、有广阔发展前景的新型可吸果冻。Abstract: Actinidia argute enzyme suck jelly was produced after fermentation and blending using Actinidia arguta as the experimental material, and the process technology was optimized by orthogonal test on the basis of single factor experiment, then the recipe of Actinidia argute enzyme suck jelly was determined by sensory qualities evaluation, finally the nutrients contents were compared with market suck jelly and juice via detecting total phenols,flavonoids and VC indicators. Results showed that the optimal process formulation was determined as follows: Actinidia arguta enzyme addition of 35%, white granulated sugar addition of 5%, citric acid addition of 0.06%, and carrageenan addition of 0.8%. The suck jelly prepared by this formula presented delicate, sweet and sour tastes,and unique Actinidia arguta aroma, and higher nutrients(total phenols, flavonoids and VC) contents compared with market products. In conclusion, this product has broad development prospect as a novel suck jelly with unique flavor and health function.
