Research Progress on Measurement of Fruit Hardness in Horticulture Crops
Fruit hardness of horticultural crops is one of the important indicators of fruit quality and maturity,which not only affects people to the degree of fruit and vegetable preference,but also closely related to storage and processing of fruits and vegetables after postharvest,fresh fruit shelf life,dehiscent fruit and so on.Therefore,it is particularly important to measure the fruit hardness of horticultural crops accurately,quickly and simply.At present,the methods for measuring fruit hardness of horticultural crops mainly include sensory evaluation method,textural analysis,acoustic feature detection,hyperspectral imaging,and near infrared spectrum technology.This review briefly introduces the principles of these measurement methods,mainly discusses the concrete application of these measurement methods,analyzes the advantages and disadvantages of each method,and discussed the development of fruit hardness measurement methods.Through the review,we hope to provide reference for the scientific research on the fruit hardness of horticultural crops.
