ABSTRACT
In the present study, an attempt was made to study on Optimizing processing and preservation techniques of sapota juice from the selected three varieties PKM 1, PKM 4 and Kirtibarthi were chosen for further study and to develop value added products from the selected varieties. Based on the juice yield, sensory quality and fruit seasonal availability the three varieties were chosen. The value added products from these varieties were developed based on clarification and concentration. The sapota pulp of the above sapota varieties were processed into clarified juice and juice concentrate. Sapota juice concentrate pH values were less change are seen in LDPE (P1) compared to other two packaging materials. The acidity of the concentrate showed slow increase through stored at low temperature. No change in TSS was seen in during storage of 3 months, which could be due to storage at low temp. The per cent total sugar and reducing sugar, PKM 1 had comparatively higher values of total sugar and reducing sugar. A small loss in ascorbic acid was observed in the varieties during storage. On storage there was appreciable increase in bacteria, fungi and yeast despite low temperature storage. Taste and flavor was best in PKM 1 LDPE packaging was found to perform better than other two packaging in retaining the goodness of the juice.
Key words: Variety, Packaging, Processing, Temperature, Juice.
