模糊数学结合响应面法优化无水瓢儿软罐头加工工艺

    Optimization of the Processing Technology of Anhydrous Soft Cans of Wild Strawberries by Fuzzy Mathematics Combined with Response Surface Method

    • 摘要: 为了解决传统瓢儿糖水罐头在加工过程中易产生后味苦涩、果肉软烂及风味物质流失等问题,选取新鲜瓢儿为主要原料,以蜂蜜、冰糖、白砂糖等为辅料,经过原料选择、清洗、护色、烫漂、硬化、装罐、蒸制后制得新型无水瓢儿软罐头。以模糊感官评价为指标,通过单因素及Box-Benhnken中心组合设计试验对无水瓢儿软罐头加工工艺进行了优化。结果表明:影响无水瓢儿软罐头品质的因素由大到小依次为混合糖添加量>蒸煮时间>瓢儿添加量,优化获得无水瓢儿软罐头最佳配方为瓢儿添加量82%、混合糖添加量23%、蒸煮时间11 min。在此条件下,所得产品具有独特的瓢儿果香味,色泽鲜艳,酸甜适口,并符合商业无菌要求。

       

      Abstract: In order to solve the problems of bitter aftertaste, soft and rotten flesh, and loss of flavor substances in the traditional sugar water can of wild strawberries during the processing, the fresh wild strawberries was selected as the main raw material, with honey, rock sugar, and white granulated sugar as the auxiliary materials. After the raw material selection, cleaning, color protection,blanching, hardening, canning, and steaming, a new type of anhydrous soft cans of wild strawberries was produced. By using the fuzzy sensory evaluation as the indicator, the processing technology of anhydrous soft cans of wild strawberries was optimized through the single factor and Box-Benhnken central composite design experiments. The results showed that the factors affecting the quality of anhydrous soft cans of wild strawberries were in the order of mixed sugar content>cooking time>canned food content, from highest to lowest. The optimal formula for optimizing the production of anhydrous soft cans of wild strawberries was as follows: the pot addition of 82%, the mixed sugar addition of 23%, and the cooking time of 11 minutes. Under these conditions, the obtained product had a unique pot fruit aroma, bright color, sweet and sour taste, and met the requirements of commercial sterility.
