About the Cover

There is an inevitable decline in quality value of ascorbic acid in storage and distribution of cashew apple juice. The quality value and optimum shelf life of yellow sample of cashew apple juice were determined and the quality value model based on the deteriorative factors was developed. The coefficient of correlation (R2) of the dependent variable (ascorbic acid or vitamin C) and independent variables (temperature, total soluble solid (TSS), pH and duration of storage) in the regression models of the sample was 0.988. Data were drawn from 34 full factorial experiments performed in three replicates with the order of the replicates randomized. A multivariate regression analysis was used for combining the variables. The model developed revealed that temperature, pH and duration of storage with some other interactions were the major factors that influence the shelf -life and also determine the character and qualities of cashew fruit juice. The developed models further revealed that 38.6OC storage temperature, 11.68OBrix value, pH of 4.61, and storage duration of 16 days of yellow sample retained ascorbic acid levels at 218.11 mg/100 ml on maximum shelf life. Equation 34 expresses the regression model for determining the shelf life of yellow sample of cashew fruit juice (Ref: Chikwado UK, Ifeanyi OW. Modeling the influence of deteriorative factors on shelf-life of yellow cashew juice on natural storage. Discovery, 2022, 58(316), 270-284).
