Abstract

Black pepper is one of the mosf popular spice traded around the globe, either in dried grain form or in bulky powder. However, for retailing purpose both are usually packaged in plastic film. This research was conducted to predict the shelf life of packaged 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 packaged in HDPE demonstrated the longest shelf life which was equal to 2187 days and for the powder equal to 2037days. The volatile oil loss tor dried gram black pepper alter 30 days of preservation was 1.36% and for the powder was 40.82%.
