Dekke mas na niura is a typical local food of North Sumatra made from carp which does not undergo cooking processes such as frying, steaming, burning, or boiling but is only paraded. This study aimed to estimate the shelf life of pasta seasonings using the Arrhenius equation model Accelerated Shelf Life Test (ASLT). This research was conducted at the Laboratory of Food Chemistry and Nutrition, Faculty of Animal Science and Agriculture, Diponegoro University, Semarang. The materials used in making seasonings dekke mas na niura are andaliman, pecan, turmeric, kecombrang / rias, onion, garlic, salt, red chili, lime, kaffir lime, galangal, and peanuts. The method used for making pasta spices is by mixing spices and grinding ingredients until smooth. Seasonings are stored at 25°C, 30°C, 35°C and 40°C for 24 hours of storage. The Analysis is carried out every 6 hours. The parameters tested were Aw value, pH value, and total bacteria (TPC). The results of the test data are then made linear regression with the making of orders 0 and order 1, then from the data, the shelf life calculation is done with the Arrhenius equation. The results showed that the highest Aw, pH, and total bacterial values were at 40°C which were stored for 24 hours. The critical point used in estimating shelf life is total bacterial order 1. Estimation of shelf life based on total bacteria is 5.6 days (25°C); 7.1 days (30°C); 5.6 days (35°C); and 5.2 days (40°C). Storage of pasta ingredients dekke mas na niura optimum at 30°C. Overall, the higher the storage temperature and storage time, the shorter the shelf life.
