中文摘要:

      目的 分析贵长猕猴桃果醋风味特征, 研发出一款贵长猕猴桃果醋饮料。方法 采用气相色谱-质谱法(gas chromatography-mass spectrometry, GC-MS)分析贵长猕猴桃果醋的风味性物质组成; 以贵州修文贵长猕猴桃果醋为原料, 以感官评分为指标, 用正交实验法研究贵长猕猴桃果醋饮料最佳配方, 并且应用储存期加速测试法(accelerated shelf life testing, ASLT)预测贵长猕猴桃果醋饮料的保质期。结果 解析出贵长猕猴桃果醋中23种挥发性风味成分, 其中主要风味物质为: 醇类、酸类、酯类、醛酮类等, 其中乙酸-3-甲基丁醇的相对含量最高, 达48.37%, 赋予贵长猕猴桃果醋主体香味。贵长猕猴桃果醋饮料最优配方为: 贵长猕猴桃果醋原液10%、柠檬酸钠0.15%、乳酸钙0.1%、白砂糖4%。应用ALST法预测贵长猕猴桃果醋饮料的保质期在24个月中以上, 可以满足市场销售需求。结论 贵长猕猴桃果醋风味独特, 贵长猕猴桃果醋饮料有天然猕猴桃果香味、色泽均匀、口感酸甜适中, 保质期合格。

英文摘要:

      Objective To analyze the flavor characteristics of Guichang kiwifruit vinegar and develop a kind of Guichang kiwifruit vinegar beverage. Methods The flavor components of kiwifruit vinegar were analyzed by gas chromatography-mass spectrometry (GC-MS). Taking Guizhou Xiuwen Guichang kiwifruit vinegar as raw material and sensory score as index, the optimum formula of Guichang kiwifruit vinegar beverage was studied by orthogonal experiment, and the shelf life of Guichang kiwifruit vinegar beverage was predicted by accelerated shelf life testing method (ASLT). Results A total of 23 kinds of volatile flavor components in Guichang kiwifruit vinegar were analyzed, and the main flavor substances were alcohols, acids, esters, aldehydes and ketones. Among them, the relative content of acetic acid-3-methylbutanol was the highest (48.37%), which gave the main flavor of Guichang kiwifruit vinegar. The optimal formula of Guichang kiwifruit vinegar beverage was: Guichang kiwifruit vinegar 10%, sodium citrate 0.15%, calcium lactate 0.1%, and sugar 4%. The shelf life of precious kiwifruit vinegar beverage was above 24 months which was predicted by the ALST method, which could meet the market demand. Conclusion Guichang kiwifruit vinegar has unique flavor. Guichang kiwifruit vinegar beverage has natural kiwifruit flavor, uniform color, moderate sweet and sour taste, and qualified shelf life.
