Accelerated Shelf Life Test (Aslt) Method with Arrhenius Approach for Shelf Life Estimation of Sugar Palm Fruit Jam With Addition of Asian Melastome (Melastoma malabathricum, l.) on Jar Packaging and Pouch

Abstract

Abstract. Base on previous studies showing that sugar palm fruit can be made as jam with the addition of Asian melastome fruit as a natural coloring. This sugar palm fruit jam product is packaged with jar and pouch packaging. shelf Life information for this product is unknown. The purpose of this study is to determine the rate of change in quality, critical parameters, and estimate the shelf life of sugar palm fruit jam with Arrhenius Model which is simulated at three storage temperature conditions (28⁰C, 38⁰C, and 48⁰C). Parameters observed during the storage process are water content, water activity (aw), pH, color (L), anthocyanin, and antioxidant activity (IC50). The results showed that the smallest activation energy value was used to determine product shelf life, it is color parameters (L) (first order reaction) with linear regression y = -4715.x + 9,787 on jar bottle packaging and y = -2021.x + 1,387 on packaging pouch. The age of storing sugar palm fruit jam with jar bottles is 93 days at 28⁰C and on the packaging pouch for 40 days at 28⁰C.

Shelf-life Estimation of Dried Chili in Vacuum Packaging

“…An increase in zero-order water content has a greater R 2 value, so the constant resulting from the zero-order equation was chosen to be used in the Arrhenius equation shown in Figure 3. Anggraini et al (2019) obtained the results of the zero-order equation for the water content quality parameters for estimation of the shelf life of brown sugar jam with the same graphic trend but different constant values. The constant value is greatly influenced by the characteristics of the product.…”

Penurunan mutu dan pendugaan umur simpan sup krim instan labu kuning diperkaya tempe untuk lansia dengan metode accelerated shelf life testing (ASLT)

“…Meskipun mengalami peningkatan, selama masa penyimpanan juga terjadi fluktuasi kadar air. Studi lain oleh Anggraini et al menunjukkan hal yang sama, bahwa kadar air selai buah pada akhir waktu penyimpanan menunjukkan peningkatan sebesar 1-2% 14 . Peningkatan kadar air dapat disebabkan oleh beberapa faktor seperti sifat higroskopis bubuk sup krim, kondisi penyimpanan dan bahan kemasan 15 .…”

Estimating the Shelf Life of Balado “DR” Cassava Chips Based on Free Fatty Acid Parameters with the Accelerated Shelf-Life Test Method Arrhenius Model

“…Food products that become rancid can be identified by the increase in the amount of free fatty acids. By keeping the sample outside of normal conditions so that the product can be degraded faster and its shelf life can be calculated, the Accelerated Storage Life Test (ASLT) method can be used to estimate the shelf life of foodstuffs (Anggraini et al, 2019). The ASLT approach was chosen because it produces excellent accuracy quickly.…”
