Abstract
ABSTRACT The effectiveness of ascorbic acid in improving the quality and shelf life of processed (smoked) mackerel fillets was investigated. The fish were divided into four ascorbic acid (AA) treatment groups and smoked for 18 hours at a temperature between 120°C and 150°C. After 28 days, the fish were tested for proximate, biochemical, microbiological, and sensory status. Based on the tests conducted, fish treated with 15 mg L−1 AA showed better nutrient composition, biochemical, and sensory qualities, while Enterobacteriaceae spp counts declined with higher AA concentrations. The study revealed that AA improved mackerel fish and extended their shelf life.
