摘要：

【目的】马铃薯块茎质地综合评价有利于对马铃薯加工品质性状的细分和准确定位用途,辅助马铃薯品种的选择和选育,同时加快马铃薯产品的开发。【方法】以主栽马铃薯品种块茎为材料,采用穿刺、二次压缩（texture profile analysis,TPA）和剪切3种质构检测模式分析块茎质构参数：穿刺距离、穿刺起始力、穿刺速度、压缩形变量、压缩速度、压缩间隔时间、压缩起始力、剪切起始力和剪切速度;根据最佳质构测试参数测定8个不同品种块茎质地参数,分析质地参数间的相关性和块茎品质评价最佳质地参数。【结果】鲜块茎穿刺最优参数：探头型号为圆柱金属探头（TMS 2 mm Steel）,穿刺距离为2 mm,起始力为2.5 N,检测速度为50 mm·min^-1;TPA压缩最优测试因素（鲜/熟）：鲜、熟块茎圆柱体样品直径和高度均为10—15 mm,检测探头的选择对鲜块茎质地无显著差别,熟块茎最优探头型号为圆柱铝制探头（TMS 36.0 mm Aluminum Cylinder）;最优参数（鲜/熟）：形变量50%/60%,检测速度60 mm·min^-1/80 mm·min^-1,间隔时间6 s/10 s,起始力均为0.7 N;剪切最优参数（鲜/熟）：长方体样品（30 mm×15 mm×10 mm）,探头型号为轻型单刀探头（TMS Perspex Knife Edge）,检测速度均为60 mm·min^-1,起始力为1 N/0.5 N。不同品种块茎相关性分析表明,弹性与薯皮脆性存在显著相关性,与穿刺和剪切其他质地参数之间均无显著相关性;鲜块茎穿刺、TPA压缩与剪切质地参数之间均存在显著或极显著正相关性（0.410—0.959）;熟块茎TPA压缩和剪切质地参数之间均存在显著或极显著正相关性（0.441—0.952）。【结论】穿刺、TPA压缩和剪切质构检测模式适合鲜块茎质地品质的客观评价,其中,薯皮硬度、薯皮脆性、TPA硬度、内聚性、咀嚼性和剪切硬度可作为比较鲜块茎质地差异的重要参数;TPA压缩和剪切质构检测模式适合熟块茎质地品质的客观评价,其中,TPA硬度、粘附性、内聚性、弹性、咀嚼性和剪切硬度可以作为比较熟块茎质地差异性的重要参数。

Abstract:

【Objective】 The comprehensive evaluation of texture qualities of potato tubers not only are beneficial to the subdivision of processing quality traits and accurately locate purpose of potato, but also assist breeders screening new varieties, and accelerate the development of potato products.【Method】Potato cultivated varieties were selected as the research samples. Puncture, TPA compression and shear methods were chosen to analyze the texture parameters. These included puncture distance, puncture initial force, puncture speed, compression deformation, compression speed, compression interval time, compression initial force, shear initial force and speed. The texture indexes of eight varieties were measured under the optimal texture analyzer parameters setting, then the correlation among the texture parameters and the evaluation of optimal texture parameters were analyzed. 【Result】 Optimal parameters of fresh tuber puncture: Cylindrical metal probe (TMS 2 mm Steel), 2 mm puncture distance and, 2.5 N initial force, 50 mm·min^-1 detection speed. The optimal test factors of TPA compression (fresh/steamed): The cylinder sample for fresh and steamed tubers both ranged in the diameter and height from 10 mm to 15 mm, no significant difference was examined among three probe selection in the fresh tubers. Cylindrical aluminum probe (TMS 36.0 mm Aluminum Cylinder) was the optimal type for steamed tubers probe. The optimal parameters (fresh/steamed): 50% and 60% deformation, 60 mm·min^-1 and 80 mm·min^-1 detection speed, 6 s and 10 s interval time, both 0.7 N initial force. The optimal shear parameters (fresh/steamed): The length, width and height of the cuboid sample were 30 mm, 15 mm, and 10 mm, respectively. The probe type was light single knife probe (TMS Perspex Knife Edge), with both 60 mm·min^-1 detection speed, and 1 N and 0.5 N initial force. They’re existed significant correlation between springiness and the peel crispness, no significant correlation among the other texture parameters of TPA compression and shear. They’re existed significant positive correlation among puncture, TPA compression and shear texture parameters (0.410-0.959) in fresh tubers. There also existed significant positive correlation between TPA compression and shear texture parameters (0.441-0.952) in steamed tubers. 【Conclusion】 Puncture, TPA compression and shear methods were suitable for the samples evaluation of the quality of fresh tubers. The indexes of peel hardness, peel brittleness, TPA hardness, cohesiveness, chewiness, shear hardness can be chosen as important parameters to compare differences of texture. TPA compression and shear methods were suitable for the sample’s evaluation of the quality of steamed tubers. The indexes of TPA hardness, adhesiveness, cohesiveness, springiness, chewiness, shear hardness can be chosen as important parameters to compare differences of texture.
