Research on the Analysis of Wax Effect in Cold Storage Based on AHPand Interval-Valued Fuzzy TOPSIS Method

摘要

In looking for different types of large-scale activities of food sanitation supervision and security modes, improvingthe efficiency of food hygiene protection, this paper establishes the evaluation index system for sports food hygiene,and proposed the sports food hygiene evaluation model based on the Analytic Hierarchy Process (AHP) and the intervalfuzzy TOPSIS method. AHP is used to determine the evaluation indexes’ weight, by means of fuzzy theory to buildinterval fuzzy matrix for calculating the positive and negative ideal solution and proximity, and based on proximity comparesports food hygiene. The effects of wax treatment on alleviating chilling injury and quality changes of pineapple fruit(cultivar ‘Paris’) during cold storage were examined. It was effective in maintaining firmness and decreasing treatableacidity of harvested pineapple fruit, suggesting that this wax treatment is a useful technique to alleviate chilling injury andmaintain fruit quality during the cold storage.
