Abstract

Mulberry pomace shows promise as a functional ingredient for dietary applications. This study aimed to assess the physicochemical characteristics, antioxidant activity, sensory acceptability, and shelf-life of the formulated spicy candied mulberry chew. Shelf life was determined using accelerated shelf-life testing (ASLT) at 25℃, 35℃, and 45℃ to predict shelf life of the product when stored at 37℃. The developed spicy candied chew (75% mulberry pomace and 25% fresh mulberries) exhibited aw of 0.5505±0.01, TSS of 67.57±0.69 °Brix, pH of 3.84±0.06, and TTA of 0.83±0.02%. It also contained a total phenolic content of 2.37±0.07 mg GAE.g-1 and antioxidant activities of 3.81±0.18 and 2.05±0.25 mg Trolox eq.g-1, as measured by ABTS and FRAP, respectively. Microbial analysis revealed that Salmonella spp. were not detected in 25 g samples, Staphylococcus aureus was <10 CFU.g-1, and Escherichia coli was <3 MPN.g-1. Sensory evaluation indicates that positive consumer acceptance ranged from 7.07.8 (n = 100). Shelf-life estimation of the product stored at 37℃, based on total plate count using the ASLT method with kinetic reaction models (  and values), was approximately 24 days. The findings indicate that the product provides added value as a functional food and promotes sustainable utilization of fruit-processing by-products.
