Influence of storage on chemical, microbial and consumer acceptability of a milk-like product made from melon seeds

Abstract

The storage stability of melon milk at room (30 ± 2 ^°C)and refrigeration (10 ± 2 ^°C) temperatures was determined by analyzing changes in the chemical, microbial andsensory properties of the milk stored for 7 days. Theresults showed that at both storage temperatures, solublesolids and pH of the milk decreased while titratableacidity increased with storage. The standard plate countsincreased appreciably while coliforms were absent in themilk with storage at both storage temperatures. The overallacceptability score of the melon milk dropped duringstorage, the drop being faster at 30 ± 2 ^°C than at 10 ± 2 ^°C. The milk samples stored at 30 ± 2 ^°C and 10 ± 2 ^°C were acceptable only within one and three days, respectively; thereafter, theywere unacceptable.
