THE APPLICATION OF SUPERHEATED STEAM IMPINGEMENT BLANCHING TECHNOLOGY IN AGRICULTURAL PRODUCTS BLANCHING PROCESS

摘要

Blanching is an essential step before processing of agricultural products as it can inactivate enzymes that cause undesirable changes.However,the widely used traditional hot water blanching has many disadvantages such as nutrients lost during blanching and pollution caused by waste blanching water.Therefore,the traditional hot water blanching should be replaced by new blanching methods.Superheated steam impingement blanching (SSIB) technology combines the advantages of superheated steam and impingement technology,results a rapid,no waste water and efficient process.This paper outlines the application of SSIB in agricultural products processing such as yam,sweet potato,grape,and sea cucumber.
