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

ABSTRACT

In looking for different types of large-scale activities of food sanitation supervision and security modes, improving the 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 interval fuzzy TOPSIS method. AHP is used to determine the evaluation indexes’ weight, by means of fuzzy theory to build interval fuzzy matrix for calculating the positive and negative ideal solution and proximity, and based on proximity compare sports 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 treatable acidity of harvested pineapple fruit, suggesting that this wax treatment is a useful technique to alleviate chilling injury and maintain fruit quality during the cold storage.
