Prediction Shelf Life of Red Fruit Spicy Sauce (Pandanus conoideus Lamk) by Using Accelerated Shelf Life Test Method

Abstract

Red fruit sauce was sauce that made from mixing red fruit paste and mikmak sweet potato flour. This reserach aimed to study the shelf life red fruit sauce with ASLT method using Arrhenius equation. The parameters of shelf life were viscosity, water content, pH, total mold, total bacteria, and organoleptic. From the six parameters, it was known that water content has the lowest activation energy (10,401.08 cal/mol) and appearance paramater of organoleptic has the highest activation energy (28,623.36 cal/mol). The lowest activation energy was used to determine product shelf life. The shelf life reaction was following ordo 1. The linier regretion was y = -703.663 (1/T) + 8.4649. The result of shelf life calculation was based on water content parameter in temperature 27°C is 25 months, in 37°C is 14 months, and in 47°C is 8 months.
