Inhibition of ACCO (1-aminocyclopropane 1-carboxylic Acid oxidase) Activity of Mangoby Modified Atmosphere Storage

Abstract

Inhibition of ACC Oxidase Activity of Mango by Modified Atmosphere Storage is aimed to extend the storage life were carried out at Food Technology Laboratory, University of Mataram from by using Completely Randomized Design and continued with Least Significant Different at five percent significance level. Mangoes were stored at Polyethylene (PE) bags; PE + KMnO4; Polypropylene bags (PP); PP + KMnO4 and unpacked (Control) for three weeks. The physical properties of fruit such as weight loss and decay percentage were determined, while physiological properties such as the rate of respiration, ethylene production including ACCO activity. Inactivation of ACCO occurred to almost half-time of its activity in mango stored at MAS as compared to unpacked mango. Therefore, paralleled the rate of respiration and production of ethylene at MAS leads to extend the storage life of mangoes. Weight loss and decay percentage of mango kept in MAS for 3 weeks were lower than unpacked.
