Abstract

Cookies are a popular food product but are generally low in dietary fiber. Innovation can be made by partially substituting wheat flour with durian peel flour (albedo), which is rich in fiber and has potential as a functional food ingredient due to its content of crude fiber, starch, flavonoids, and other bioactive compounds. However, the addition of fiber may affect the quality and shelf life of the product. Therefore, shelf life estimation is essential to ensure product quality stability and safety during storage. This study aims to determine the difference in shelf life of cookies substituted with durian inner skin flour at temperatures of 25⸰C, 35⸰C, and 45⸰C. The shelf life was estimated using the Arrhenius model over 28 days of storage, with observations every 7 days, and moisture content as the quality parameter. The research used a laboratory experimental design with a Randomized Block Design (RBD). Results showed that the shelf life of cookies decreased with increasing storage temperatures: 26 days at 25°C, 24 days at 35°C, and 21 days at 45°C. Statistical analysis indicated no significant differences in shelf life across the different temperatures. It can be concluded that at 25°C, the cookies have a shelf life of 26 days, while at 35°C the shelf life decreases to 24 days, and at 45°C it further decreases to 21 days. Statistical analysis showed no significant differences between storage temperatures. It can be concluded that the shelf life of cookies decreases with increasing storage temperature—26 days at 25°C, 24 days at 35°C, and 21 days at 45°C—although the differences were not statistically significant. Further research is recommended by including microbiological tests, sensory evaluations, and special packaging treatments.
