果品静载流变特性的研究进展

本文通过对国内外各类果品的静载压缩流变特性研究现状的分析，指出了在果品的静载流变学研究领域内存在的主要问题，提出了今后果品流变学研究中需要加强和进一步研究的内容：1)加强对采后各阶段受压时果品的微观组织结构、生理生化过程的变化以及储运环境温度等因素与流变损伤效应的交叉性影响的研究； 2)加强对实际储运中较多出现的多果接触、受压问题的系统性研究；3)重视研究储运受压后流变损伤的发展与果品储藏品质关系的研究；4)根据国内外生产实际，应加强特色果品的流变学研究,像西瓜、甜瓜等，既具有较高的营养价值和经济价值，又在世界范围内广泛种植。同时，提出了以果品本身的粘弹性为依据，在ADAMS软件平台上利用计算机虚拟样机技术建立流变学模型并获得相应参数的新方法。

Review of research advances in rheological properties of fruits under static loading

The research advances in rheological properties of fruits under static loading were reviewed and some problems which existed in present studies were pointed out. The following studies should be further conducted in the future. These include: 1) Studies on the changes of micro-tissue composition, and physiological and biochemical processes of fruits at different stages after being picked, and the interactive effects caused by factors such as storage temperature, transportation conditions and rheological damages should also be paid more attention to; 2) systematic study on touching and pressing during storage and transportation should be intensified; 3) studies on the relationship between the development of rheological damages caused by pressing during storage and transportation and storage properties of fruits should be emphasized; 4) rheological studies on specific fruits should be stressed in fruit production. Fruits like watermelons, muskmelons are distinctively tasty, highly nutritious and have higher market values. Besides, they are capable of being grown in many areas around the world. Finally, a new way to set up rheological models and compute corresponding rheological parameters by use of virtual prototyping technology of ADAMS software was put forward.
