Shelf-life Estimation of Instant Pempek Rajungan (Portunus pelagicus) Rancidity with the Arrhenius Acceleration Method (original) (raw)

Rancidity is one of the potential damages to the instant pempek rajungan (Portunus pelagicus) during storage. The purpose of this study was to estimate the shelf life of instant pempek rajungan packed with polypropylene plastic (PP) based on the relationship between storage temperatures and free fatty acids produced. Estimation of shelf life using the acceleration method based on the Arrhenius model. Samples were stored for 30 days at three different temperatures, 25 ± 2 °C, 35 ± 2 °C, and 45 ± 2 °C. The parameter observed during the storage process was an assessment of the rancidity level based on the free fatty acids formed in the sample. Data were analyzed using linear regression and the equation obtained was used to calculate the shelf life of pempek rajungan at room temperature (27 °C). The results showed that the storage time for instant pempek rajungan products at temperatures of 25 ± 2 °C, 35 ± 2 °C, and 45 ± 2 °C could be estimated to be 78, 86, and 70 days respectively wit...
