STABILITY EVALUATION OF CANDLENUT OIL CAPSULE

Abstract

Candlenut oil is a promising source of omega, it contains up to 90% of omega fatty acids. Due to its being rich in unsaturated fatty acids, the susceptibility of oxidation increases. In order to prevent the omega fatty acids degradation in candlenut oil, it is inserted into capsule as a food supplement product. The best capsule material, opacity, and storage condition to preserve candlenut oil quality were studied. Three factors, capsule material, opacity, and storage temperature were varied during this study, the capsules were gelatine based and seaweed based. The capsule opacity was classified into coloured and transparent capsule. The storage condition was differ in temperature, cool temperature (RH 33%, ± 8°C), and room temperature (RH 65%, ± 28°C). The best capsule material and optimum storing temperature of candlenut oil capsule were evaluated based on three parameters, such as disintegration time, iodine value analysis, and omega content analysis. There is no significant difference in disintegration time of both capsules, disintegration time of gelatine based and seaweed based capsule are 5.8 and 5.78 minutes, respectively. Both gelatine and seaweed capsule are capable of preventing omega degradation. It is recommended to store the capsule in cool temperature.
