摘　　要：为建立量化评价三华李果实质地品质方法提供理论依据,利用质构仪穿刺试验法对三华李果实质地参数进行测定。以‘麒麟’三华李为材料,以贯入距离、贯入速度、接触力以及穿刺部位为单因素参数,通过质构仪P2探头,对三华李果实进行穿刺力学实验,分析果实质地变化,包括果皮强度、果皮脆性、果皮破裂距离、果皮韧性、果肉硬度、果肉黏聚性、果肉胶着力,确定最佳质地特性测定的条件。结果显示,三华李果实质地特性最佳测定条件为触发力15 g,穿刺距离9 mm,贯入速度1 mm/s,果实中部穿刺。果皮韧性与果皮破裂距离呈极显著正相关,与果皮强度呈显著正相关。研究初步建立了利用质构仪穿刺试验法量化评价三华李果实质地品质的方法,丰富了三华李质地评价内容。The purpose of this study was to provide a theoretical basis for establishing a quantitative evaluation method of Sanhua plum fruit texture quality,and determine the texture parameters of Sanhua plum by texture analyzer puncture test.‘Qilin’Sanhua plum fruits were used as the material,the penetration distance,penetration speed,contact force,and puncture site were tested as single factor parameters.Through the probe P2 of texture analyzer,the puncture mechanical experiment of Sanhua plum fruit was carried out,and the changes of fruit texture were analyzed,including peel strength,peel fragility,peel rupture distance,peel toughness,pulp hardness,pulp cohesiveness,and pulp adhesion,so as to determine the best conditions for measuring texture characteristics.The results showed that the optimal parameters of trigger force,puncture distance,and penetration speed for determing Sanhua plum fruit texture quality were 15 g,9 mm,and 1 mm/s,respectively.The best puncture site was in the middle part of the fruit.Peel toughness was significant positively correlated with peel rupture distance and pulp hardness.The quantitative evaluation method of fruit texture quality of Sanhua plum by texture analyzer piercing test was preliminarily established,which enriched the content of texture evaluation of Sanhua plum.
