SHELF LIFE DETERMINATION OF FOAMER USING ACCELERATED SHELF LIFE TEST (ASLT)
Daftar Isi:
- PT. Kievit Indonesia is one of the company with international standard which produce encapsulated functional ingredients such as foamer and creamer. The objective of this research are to determine the shelf life of foamer using Accelerated Shelf Life Testing (ASLT), analyze the effect of different storage temperatures to chemical, physical, and sensory properties of foamers, to calculate the degradation rate of foamers during storage (Q10) based on sensory and physicochemical changes. Another objective of this research is to analyze the correlation between sensory and physico-chemical parameters. Foamer were stored in climatic chamber for sixteen weeks at 20°C and 30°C, eight weeks at 40°C with 75% relative humidity. Observation of physico-chemical and sensory were done every two weeks for foamer which stored at 20°C and 30°C. Foamer that stored in 40°C was observed every week. In foamer quality test there were physical and chemical analysis. Parameters that tested are moisture content, water activity, fat content, ash content for chemical analysis and bulk density, foam height, and color for physical analysis. Sensory analysis also performed in this researched using Two Alternative Forced Choice (2-AFC) Test. The correlation analysis showed that the increasing of moisture content as main parameter followed by the increasing of water activity, ash content, and bulk density. Adversely, the correlation between moisture content and fat content was inversely, the increase of moisture content followed by decreasing of fat content. The shelf life calculation of foamer based on moisture content was 6,28 weeks at 20°C, 2,42 weeks at 30°C, and 1,93 weeks at 40°C. The Q10 value was at 20°C and 30°C was 1,84 and Q10 value at 30°C and 40°C was 1,7.
