Black pepper is one of the most popular spices traded around the globe, either in dried grain form or in bulky powder. However for retailing purpose both are usually packages in plastic film. This research was conducted to predict the shelf life of package black pepper (both dried grain and powder) by applying isotherm sorption and Labuza models. Initial moisture content of dried grain was 12.17% d.b and for the powder was 10.27% d.b. The shelf life of black pepper calculated for the dried grain was longer than the powder. When stored at 90% RH, the dried grain black pepper package in HDPE demonstrated the longest shelf life which was equal to 2187 days and for the powder equal to 2037 days. The volatile oil loss for dried grain black pepper after 30 days of preservation was 1.36% and for the powder was 40.82%.
