Abstract: The status quo and history of the studies on rheology of compression of fruits and vegetables is reviewed.Some problems are pointed out.Those are:1)All the studies have been focused on the few varieties of apples,oranges,berries,pears and peach and potatoes;2)The mechanical properties and rheological damage of the fruits and vegetables were studied without combining other properties.3)The studies on theological damages combining with thermal properties are very few;4)Only compressions of single sample were studied,compressions of several samples have never been conducted.Some study directions to be taken in the future are pointed out:1) The study of theology on melons should be reinforced according to the physiological structure and plant characters of melons in north-west regions in China;2)Rheological study on melons will be taken combining with the tissue 'turgor pressure change and biochemical changes during compression;3)Rheological study on fruits should be taken combining with their thermal properties;4)Damage development will be studied after compression in order to predict shelf-life of fruits;5)Pakage system will be designed perfectly on the basis of compressive tests of both single sample and several samples.
