Abstract

Purwaceng coffee is a varian of coffee products that has benefits for human health. The quality of purwaceng coffee has significantly related with their shelf life. However, many purwaceng coffee producer still predicts the shelf life manually without scientific method, which has relatively low accuration. Therefore, many studies have been conducted to overcome that poblem in order to extend their shelf life. Packaging-based prediction used since that method could detemine the shelf life of the poduct adequately. The aim of this study is to analysis quality deterioration of purwaceng coffee and determine their shelf life based packaging variation. The packaging used were PAP 0.11, AF 0.05, PP 0.05, PP 0.03, and PE 0.03. The quality deterioration of purwaceng coffee was measured by 6 parameters, namely water content, water activity (Aw), weight, pH, colour, and antioxidant activity. Water content was determined by thermogravimetry method, colour by chromameter, and determination of antioxidant activity was carried out by DPPH method. Futhermore, the product shelf life test was performed using the critical moisture content method. The longest shelf life of coffee product was reached by AF 0.05 which has shelf life of 322 days and permeability value of 0.27 g H2O/mmHg.m2.day.
