| Abstract | The study aimed to optimize the repacking solution formulation of pickled ‘Carabao’ mangoes using response surface methodology. In particular, the study (1) evaluated the effects of predetermined days after harvest on the quality of pickled ‘Carabao’ mangoes; (2) established and validated the optimized repacking solution formulation of pickled ‘Carabao’ mangoes using response surface methodology; and, (3) characterized the physico-chemical, proximate, microbiological, and sensory attributes of the optimized pickled ‘Carabao’ mangoes. The appropriate predetermined day after harvest utilized in the study was 3 days after harvest (120 days after flower induction + 3 days after harvest) based on sensory evaluation (appearance, color, aroma, texture, flavor, and overall acceptability scores). Optimization of the repacking solution formula was based on the effects of salt content (% w/v), sugar content (% w/v), and vinegar content (% v/v) on the pH, titratable acidity (% acetic acid), and total soluble solids (°Brix). The optimum formulation with a desirability index of 0.395, was determined to be 2.73%, 33.33%, and 0% for salt content, sugar content, and vinegar content, respectively. The model was subsequently validated and proven to be valid at an α = 0.05 significance level. Characterization of the optimized repacking solution formulation produced pickled mangoes that were able to meet product standards for physico-chemical and microbiological attributes. Moreover, results of the sensory evaluation indicated that the product was acceptable to consumers, garnering scores between “like slightly” and “like very much” for all attributes. |
