Abstract

PT. Kievit Indonesia produces non-dairy creamer intended to substitute dairy cream products as an additive to coffee or other beverages. Flavored non-dairy creamer made by combining the ingredients and additives that contribute to a milk-like taste. The objectives of this research were to determine the shelf life of flavored non-dairy creamer in three level temperatures using accelerated shelf life testing (ASLT) and to calculate the degradation rate of creamer during storage (Q10). Other objectives of this research was to analyze the effect of different storage temperatures on the sensory, physical and chemical properties of creamer, as well as to evaluate the correlation among them. Flavored non-dairy creamers were stored in climatic chamber for 8 weeks at 40oC and 16 weeks at 20oC and 30oC. The Relative Humidity (RH) was set at 75%. The observations were done once a week for the products that were stored at 40oC and every 2 weeks for product that was stored at 20oC and 30oC. The observed parameters were physical (coffee test, color, flowability and bulk density), chemical (moisture content, water activity, ash content, and fat content) and sensory (flavor overall and mouthfeel). The correlation analysis showed that the increasing of moisture content was followed by the increasing of water activity, sinkability, flowability, and bulk density. The shelf life of flavored non-dairy creamer based on moisture content was 69.26 weeks at 20oC, 21.74 weeks at 30oC, and 7.35 weeks at 40oC. The Q10 value was 3.19 (between 20oC and 30oC) and 2.95 (between 30oC and 40oC).
