Abstract


The present study was conducted to develop and investigate pineapple (Ananas comosus) preserve and candy to assess its prospect in marketability and study their storage life. Pineapple slices were treated with 2% solution of common salt to prevent browning, then cut into cube shape and treated with 1% calcium chloride and 0.25% potassium metabisulphide solution and finally processed. The preserves were processed with 60° Brix, 65° Brix and 70° Brix sugar syrup. The candies were processed with 65° Brix, 70° Brix and 75° Brix sugar syrup. Initially the composition of pineapple preserves processed with different level of sugar ware found in the range as moisture content 33.09-35.65%, ash 1.36-1.42%, protein 1.01-1.07%, fat 0.61-0.66%, total sugar 61.37-63.73% and reducing sugar 30.52-31.46% and pineapple candies were found in the range as moisture content 19.05-20.88%, ash 1.52-1.58%, protein 1.15-1.21%, fat 0.72-0.77%, total sugar 75.70-77.35% and reducing sugar 45.16-46.39%. The sensory results showed that color, flavor, texture, taste and overall acceptability scores differed significantly (p<0.05). The preserve (P2) processed from 65° Brix sugar syrup and the candy (C2) processed from 70° Brix sugar syrup was the favorite sample of the sensory evaluation with the highest overall acceptability among others of the similar product. The shelf-life of candy (6 month) packed in high-density polyethylene bag is higher than preserve (4 month) packed in glass bottle when stored at ambient temperature (27° C to 30°C).

Author Keywords: Pineapple, preserve, candy, nutritional evaluation, organoleptic properties and storage life.
