Aceh noodle seasoning was made from red chili, red onion, garlic, cardamom, turmeric, ginger, cumin, candlenut, coriander and pepper. All ingredients were mashed and then sauteed in a frying pan with the addition of cooking oil. In the food industry it is necessary to determine the shelf life so the consumers know the quality of the product. Shelf life is the periode of a product from the production process until the product has decreased in quality or is not suitable to consumption. This research was conducted using a semi-empirical accelerated shelf-life testing method with the Arrhenius equation. The estimation of shelf life was determined through the quality change of Aceh noodle seasoning which packed with aluminum foil packaging and stored based on temperature factor (room temperature, 40o C, and 50o C). Each sample was analyzed of thiobarbituric acid test, flavour and descriptif test in duplicate. The results show that Aceh noodle seasoning shelf life based on the critical parameters  stored at room temperature (27-30oC) was 71 days, at 40oC was 49 days, and at 50oC was 35 days.

In this paper, we report on the structure, magnetic properties and magnetocaloric effect in NaZn13-type LaFe11.1Co0.8Si1.1Bxalloys close to room temperature. The stable NaZn13cubic structure phase (space group isFm-3c) can easily obtained by annealing at 1080 °C for 225 hours. The maximal values of magnetic entropy change for LaFe11.1Co0.8Si1.1Bx(x=0.2, 0.25) were found to be 5.3 and 5.9 J/kg K at Curie temperature for a magnetic field change in 0-1.5 T, respectively. The calculated refrigerant capacity for a field change in 0–1.5 T is about 147 and 107 J/kg K, for LaFe11.1Co0.8Si1.1B0.2and LaFe11.1Co0.8Si1.1B0.25respectively, which is as larger as those of Gd(99.3%) alloy
