Different lowercase letters in the same row indicate significant differences (p < 0.05) between treatments at same analysis day. Different capital letters in the same column indicate significant differences (p < 0.05) between each treatment at different analysis day. Total soluble solids (TSS) are expressed in °Brix. Polyphenol oxidase (PPO) activity is expressed in increase in absorbance/0.1 mL of extract.
