Gac fruit (Momordica cochinchinensis Spreng) is indigenous to Vietnam and other countries in Southeast
Asia. Its seed pulp contains high concentrations of carotenoids, especially the pro-vitamin A, betacarotene.
Due to regulatory issues and consumer demands, industrialized food products need to clearly
state their shelf-lives, that is the time within their characteristics are kept at acceptable levels, in their
packages. Nowadays consumers demand products with superior appearance, texture, taste and flavor
whilst keeping their nutritional value. Thus, food companies need to carry out kinetic studies whenever a
new or modified product is to be launched onto the market. The purpose of this study was to develop a
method to investigate the changes of total carotenoids content of Gac powder product in accelerated
temperature to find out the appropriate temperature and shelf-life of product storage. The result shows
that total carotenoid content maintains at 70% in comparing with the beginning content in three months at
10 0C or five months at 5 0C in condition of absent oxygen and light.
