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.
