Non-destructive detection method for quality of apple when stored in refrigerator and shelf

Abstract

The related no-damage test method for apple cold preservation and shelf quality comprises: with knocking vibration and chromatic meter, obtaining the no-damage hardness factor S at different stage and fruit surface tone angle value H, combing with sense evaluation, building opposite template, and obtaining the formula as S=at2-bt+S0 and H=at2-bt+H0. This invention is simple and convenient, reduces loss, and benefit to both consumer and super market or enterprise.

Description

technical field [0001] The invention relates to a method for non-destructive testing of apple refrigeration and shelf quality, mainly based on knocking vibration and color templates for non-destructive testing of apple refrigeration and shelf quality. Background technique [0002] Since 1992, my country's apple production has surpassed that of the United States and ranked first in the world. From 1996 to 2000, my country's apple export continued to grow, with an average annual growth rate of 16.5%. However, my country's total apple export accounts for only about 1.5% of the total apple production, which is obviously small compared with developed countries. The degree of industrialization of domestic apple production is low, the standardization is not enough, the commercial processing, storage, processing capacity and technical level are low, and the cold chain circulation is still in its infancy, resulting in uneven quality of apples. The proportion of high-end apples that ...

Problems solved by technology

[0005] At present, the research on apple grading at home and abroad is relatively extensive. There are not only studies on the appearance quality of apples, including fruit color, size, fruit shape, smoothness, damage, diseases and insect pests, maturity, etc., but also internal quality, including sugar and acid conte
