基于成熟度的库尔勒香梨后熟特性及对运贮品质影响数值化研究

Korla fragrant pear is one of the main product fruits in Xinjiang. Postharvest transportation and storage is necessary link of Korla fragrant pear postharvest processing, when they are picked their own properties and postharvest processing conditions determine the commodity value of fragrant pear.Harvest maturity, postharvest after-ripening characteristics and the demand of transportation storage well matched is an effective way to improve the quality of transportation storage. On the basis of the preliminary quantitative maturity of fragrant pear, this study selects the describable physical and chemical indicators of physical sensations quality and intrinsic nutritional quality to describe after-ripening characteristics and transportation storage conditions numerically, studying the influence of vibration and mechanical transfer characteristics on fragrant pear quality damage in stacking and transport process. This topic also studys the influence of different storage conditions on fragrant pear storage quality, based on the actual demand of production processing, carrying out the analysis of mathematical statistics, screening the characterization factor which can be characterized by after-ripening characteristics and transportation storage requirements, building after-ripening models, studying the change rule of different maturity quality of fragrant pear combining with two conditions of transportation storage, revealing fragrant pear after-ripening characteristics and its effect on mechanism of transportation storage quality, illuminating adaptation features of after-ripening characteristics combining with transport and storage conditions, providing the basis and reference for harvest and postharvest transportation storage process of Korla fragrant pear.

库尔勒香梨是新疆主产水果之一，采后运输和贮藏是库尔勒香梨采后加工的必经环节，香梨采摘时自身的属性和采后运贮条件共同决定香梨的商品价值，香梨采摘成熟度、采后后熟特性与运贮需求的匹配是提高香梨运贮品质的有效途径。本研究在前期量化评价香梨成熟度的基础上，针对不同运输和贮藏条件下香梨的后熟特性开展研究，选取可描述香梨外在感官品质和内在营养品质的理化指标和电学参数对香梨采后的后熟特性进行数值化描述，研究香梨堆码和运输过程中振动和力学传递特性对香梨品质损伤的影响；研究不同贮藏条件对香梨贮藏品质的影响，以香梨运输和贮藏的实际需求为依据开展数理统计分析，筛选可表征后熟特性和运贮要求的表征因子，建立香梨的后熟模型，结合采后运输和贮藏两种工况研究不同成熟度香梨品质的变化规律，揭示香梨后熟特性及其对香梨运贮品质的影响机理，阐明香梨后熟特性与运贮条件结合的适配特性，为香梨的采收和采后运输和贮藏工艺提供参考依据。
