Pengaruh Jenis Kemasan terhadap Umur Simpan Ekstrak Buah Andaliman dengan Metode Accelerated Shelf-Life Test Pendekatan Arrhenius

Abstract

Andaliman is an endemic flora from Lake Toba region and it is commonly used as a spice by the Batak ethnic community. Andaliman fruit in extract form has a lot of potential as an antimicrobial, anti-inflammatory and antioxidant. All the benefits possessed by andaliman extract have the potential to be widely used by the community. Therefore,, it is crucial to know the shelf life of andaliman fruit extract and which type of packaging is most suitable to extend its shelf life. This study aims to estimate the shelf life of andaliman fruit extract and the packaging that can extend the shelf life of the extract. The estimated shelf life was calculated based on ASLT method using Arrhenius approach under the flavonoid content parameter wich has the lowest activation energi, compared to the phenol content and antioxidant activity parameters. This study used two types of packaging, namely glass bottles and plastic bottles stored at 37°C, 45°C, and 55°C for 1 month with weekly testing. The results showed that andaliman fruit extract with plastic bottle packaging can last for 7.8 months at 37°C and 6.8 months at 55°C. While using glass bottle packaging, andaliman fruit extract can last up to 12.4 months at 37°C and 10.5 months at 55°C. Based on these data, it is known that the shelf life of extracts is influenced by storage temperature and packaging. The higher the temperature, the shorter the shelf life and the lower the permeablity of the packaging, the longer the shelf life.
