Standardization of recipes for preparation of sweet potato jam

Abstract

A comparative study was done to determine the most suitable combination of two cultivars of sweet potato for jam preparation. Two best cultivars of sweet potato selected for preparation of jam with varing sugar concentration, one is purple flesh V1 Cultivar (TSP-12-14) and another is orange flesh V2 Cultivar (ST-14), and study the storage life and biochemical constitute of jam during storage period 0 days to 30 days. T1 V1 = 1KG PULP (cv. TSP-12-14) + 1KG SUGAR, T2 V1=1KG PULP (cv. TSP-12-14) + 900 GM SUGAR, T3 V1=1KG PULP (cv. TSP-12-14) + 800 GM SUGAR, T4 V1=1KG PULP (cv. TSP-12-14) + 700 GM SUGAR, T5 V2 = 1KG PULP (cv. ST-14) + 1KG SUGAR, T6 V2=1KG PULP (cv. ST-14) + 900 GM SUGAR, T7 V2 =1KG PULP (cv. ST-14) + 800 GM SUGAR, T8 V2=1KG PULP (cv. ST-14) + 700 GM SUGAR.During observation best results found in T1 V1 = 1 KG PULP (cv. TSP-12-14) + 1 KG SUGAR T2 V1=1 KG PULP (cv. TSP-12-14) + 900 GM SUGAR, T5 V2 = 1 KG PULP (cv. ST-14) + 1 KG SUGAR, T6 V2=1 KG PULP (cv. ST-14) + 900 GM SUGARThis 4-sugar concentration performs good.
