Alkaline drink can be categorized under non alcoholic, non carbonated beverage having
pH above 7.0. It is maintained in-between 7.5-9.5 pH range. It can be developed as a
natural drink or as an artificial drink which having several health benefits. Watermelon
is one of the fruit having extremely alkaline properties with compared to other fruits.
The development of alkaline drink using watermelon is the main objective of the study.
In this study matured watermelon fruit is selected and the fruit juice is extracted.
According to the parameters of the juice collected sugar syrup is prepared to get the
final brix value of the drink. After adding all the ingredients the final drink is
pasteurized after bottling. The experiment work was carried out to evaluate the
organoleptic and physical properties such as colour, odour, taste, saltiness, sweetness,
acidity and overall acceptability. pH, brix value and microbiological conditions were
determined throughout the shelf life.
Significant differences in pH were recorded after one month from the date of
manufacture but significant differences of the brix values and microbiological safety
were not recorded. The lime flavoured sample (i.e. 7.8 pH, 11.0 brix value) was
selected as most acceptable product by acquiring highest mean rank.
