Estimations of shelf life of catfish skin crackers in polypropylene plastic packaging using the ASLT (Accelerated Shelf Life Testing) method

This research aims to determine the shelf life of catfish skin crackers in polypropylene plastic packaging using the ASLT method. This test was conducted in the Fisheries Product Processing Laboratory of the Faculty of Fisheries and Marine Sciences, Padjadjaran University and testing the content of water content and TBA (Thiobarbituric Acid) of catfish skin crackers at the Food Technology Laboratory, Faculty of Food Science Technology, Padjadjaran University from September to November 2018. This study used an experimental method consisting of 3 storage temperature treatments at 25 ºC, 35 ºC and 45 ºC. Observations carried out include sensory (hedonic) test, water content test, and TBA (Thiobarbituric Acid) test. For the calculation, Arrhenius model was chosen with odor as a critical parameter to determine the shelf life which had the biggest R2 value with equation Arrhenius Ln K = 1079.8 (1/T) – 5.5161, with R2 value equal to 0.9212. The shelf life of catfish skin crackers that was saved at the room temperature (25 ºC) was 39 days or 1.3 month.
