摘要
该文旨在制备一款以黔产野生猕猴桃为主要原料的果酱并对果酱在体外的抗氧化功能进行初步的研究。通过单因素试验探讨白砂糖添加量、柠檬酸添加量、增稠剂添加量等工艺参数对黔产野生猕猴桃果酱质量的影响,从而确定黔产野生猕猴桃果酱基本加工工艺。通过设计正交试验,采用加权评分法与感官评价分析确定黔产猕猴桃果酱的最优工艺配比为白砂糖的添加量为50%,黄原胶0.6%+海藻酸钠0.6%,柠檬酸添加量0.5%。采用清除1,1-二苯基苦基苯肼(1,1-diphenyl-2-picryl-hydrazyl,DPPH)法对果酱在体外的抗氧化性进行测定,试验结果表明本试验中黔产野生猕猴桃果酱对DPPH自由基的IC50值为10.898 mg/mL,该果酱在体外具有一定的抗氧化活性。
The purpose of this project was to prepare a jam based on wild kiwifruit as raw material and conduct preliminary research on its antioxidation function in vitro.The effects of certainamounts for sugar,citric acid and thickener on the quality of wild kiwifruit jam were discussed.The basic processing technology for preparation of wild kiwifruit jam was determined.Through the design of orthogonal tests,the best ratio of finished products was obtained.Using the weighted scoring method and sensory evaluation analysis,the optimal process ratio for making kiwifruit jam was 50 % white granulated sugar,0.6 % xanthan gum,0.6 % sodium alginate,and 0.5 % citric acid.The antioxidant activity of jam in vitro was determined using 1,1-diphenyl-2-picryl-hydrazyl(DPPH)method.The experimental results showed that wild kiwi fruit was produced in this experiment.The IC50 value of jam on DPPH free radical was 10.898 mg/mL.The jam had certain antioxidant activity in vitro.
