钙果穿刺试验的质构特性与分析

目前钙果采摘后的品质评价尚未确立。通过测定5种钙果果实的基本物性参数以及研究不同品种、穿刺方位对果实穿刺质构特性的影响，编辑力-时间穿刺分析方法，建立4个穿刺参数来表征果实质构特性，分析钙果品种、穿刺方位对各质构参数的影响。分析表明，不同品种间的基本物性参数差异显著（P﹤0.05）；品种、穿刺方位对果皮硬度、果皮破裂深度、果皮韧性以及果肉平均硬度均有极显著性影响（P﹤0.01），影响的主要因子依次是穿刺方位，品种。该研究结果表明了钙果品种间存在质构特性差异，丰富了钙果品质评价，也为钙果的机械采收、加工提供了技术参考。 

Analysis of Texture Properties in Cerasus humilis Based on Puncture Test

Quality evaluation after current picking of Cerasus humilis has not been established.Basic physical parameters of five kinds of Cerasus humilis were determined and effects of different varieties and puncture orientation on texture characteristics of fruit puncture were studied.Editing force-time puncture analysis method was established to establish four puncture parameters to characterize fruit texture.The analysis showed that basic physical parameters of different varieties were significantly different （P<0.05）； the variety and puncture orientation had significant effects on peel hardness，peel rupture depth，peel toughness and average hardness of pulp （P<0.01）.Main affecting factors were puncture orientation and variety.Results indicated that there were differences in texture characteristics between Cerasus humilis varieties，which enriched quality evaluation of Cerasus humilis，also provided technical reference for mechanical harvesting and machining of Cerasus humilis.
