Resource Title Optimization of the Repacking Solution of Pickled 'Carabao' Mangoes (Mangifera indica L. cv. Carabao) Using Response Surface Methodology
Date Issued 11 June 2019
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.
