The following physico-chemical properties can be measured for quality assurance purposes. Properties should be uniform every batch. Adjustments can be computed using Pearson’s Square formula. All artificial preservative can be omitted but will cause decrease in product shelf life.
a. sugar content. Sugar concentration can be increased by adding sugar or can be lowered by adding water or pulp.
b. pH. This can be lowered by adding citric acid or can be increased by adding water or pulp.
c. titrable acidity. Same as in (a), just replace sugar with citric acid. Be cautious because citric acid affects both pH and titrable acidity.
