Abstract

Non-dairy creamer was used as a milk and dairy cream replacer in serving beverages such as coffee and tea. Non-dairy creamer contains several ingredients such as sweetener, protein, vegetable oil/fat and other artificial ingredients like stabilizer and emulsifier. During the storage time, the quality of non-dairy creamer could be changed because of the improper storage condition including storage temperature and humidity level. This research was conducted to know the effect of different storage temperature to the quality of the non-dairy creamer. Another objective of this research was to determine the shelf life of non-dairy creamer using ASLT method. This research was consists of two steps, i.e. non-dairy creamer storage and the final product quality test. During storage, the products were stored in climatic chamber for about four months with three different levels of temperatures. The products were stored at temperature of 20oC, 30oC, and 40oC with the relative humidity at 75%. The analyses conducted were physical (coffee test, flowability, powder color and bulk density), chemical (moisture content, water activity, ash content, fat content), and sensory analysis. The observation was done once every two weeks for 20oC and 30oC and once a week for extreme temperature (40oC). Determination of the shelf life of non-dairy creamer was done based on Arhennius equation approach. The shelf life of non-dairy creamer based on moisture content was 15.574 weeks for non-dairy creamer stored at 20oC, 7.5758 weeks for non-dairy creamer stored at 30oC and 3.8577 weeks for non-dairy creamer stored at 40oC. The Q10 value of the product (between 20oC and 30oC) was 2.056. While, the Q10 value of the product (between 30oC and 40oC) was 1.964.
