模拟超市销售期间圣女果质构特性变化的研究

Study on texture characteristic changes of cherry tomato during the shelf phase

采用TPA(texture profile analysis)测试法和感官评价相结合的方法,测定模拟超市销售期间圣女果货架期质构特性和品质变化指标,并对其相关性进行分析。结果表明,TPA测试圣女果的各项质构参数能够在不同方面反映圣女果在货架期间的品质变化特性,货架期4d是圣女果质构特性及其它品质变化的拐点,货架期6d时所有质构特性及品质会急剧下降。质构参数硬度与感官评分呈极显著正相关(P<0.01),咀嚼性与感官评分呈显著正相关(P<0.05),表明主要质构参数测定可用于预测圣女果在此条件下的品质变化。

Cherry tomato is one of the principal fruits in supermarket,with bright color,delicious taste,pleasant flavor and rich nutrients.The quality profiles of cherry tomato during the simulation of supermarket sales were investigated by TPA（texture profile analysis） and sensory evaluation methods.The results indicated that the quality of cherry tomato was stable after 4d during the storage,however,it decreased rapidly after 6d,and the changes of texture parameters by TPA were in coincidence with the tendency of sensory values.In addition,the correlation analysis of texture parameters by TPA and sensory values showed that hardness parameter and sensory values were extremely significantly different（P0.01）,and chewiness parameter and sensory values were significantly different（P0.05）,which implied TPA was potential for the predication of quality of cherry tomato under this condition.
