ABSTRACT A study to determine the stability of the premix for use in manufacturing when kept in storage at ambient conditions for two weeks and the stability of vitamin A in fortified peanut butter at the target shelf-life of six months was conducted, to comply with the Philippine Department of Health’s technical requirements for the application of Sangkap Pinoy Seal. Result of stability test for the premix showed that it is stable at the target holding period of twelve days at ambient conditions without affecting its vitamin A content and its odor and color characteristics. During the twelve days holding period, the premix was evaluated by trained panelists as negative for change in color and presence of rancidity. The vitamin A content and peroxide values, despite slight changes, remained acceptable at the end of the two weeks holding time. Results of shelf-life testing of fortified peanut butter at accelerated temperatures of 35, 40 and 45 o C showed that vitamin A degradation, oil separation and development of rancid odor occurred at a faster rate at accelerated temperatures. The vitamin A added in the fortified product was predicted to have a shelf-life of 194 days or 6.5 months when stored at 30 o C, based on 20% loss of vitamin A from the claimed value of 4.6 μg retinol/g peanut butter. Based however on the combined physical, chemical and sensory characteristics of the product, the fortified peanut butter was predicted to have a shelf-life of 188 days or 6.25 months. Above data indicates that the vitamin A added will remain stable at the target shelflife of 6 months. 262
