Determination Of The Shelf Life Of Black Sesame Body Scrub Powder With The Accelerated Shelf Life Testing Method Model Labuza

Abstract

Shelf life is an important aspect and requirement in the production of a product. Until now, the shelf life of black sesame body scrub powder products is still unknown. This study aims to determine the sorption isotherm characteristics of water and the shelf life of black sesame body scrub powder using the Accelerated Shelf Life Testing Model Labuza method. This research was conducted in two stages, namely analysis of water sorption isotherm characteristics and estimation of shelf life. The results showed that the water sorption isotherm characteristics of black sesame body scrub powder were sigmoid (type II) and the shelf life of the product at 28^oC, 75% humidity, in polyethylene packaging of 0.13 mm thickness, cross-sectional area of 0.064 m², with a sample weight of 1000 g was 19.65 months or 1.6 years while with polyethylene packaging of 0.13 mm thickness, cross-sectional area of 0.0234 m2, with a sample weight of 100 g was 5.37 months or 0.4 years.
