“Influence of Chemical Preservatives and Pasteurization Temperature on Preservation of Custard Apple Pulp in Deep Freezer”

Abstract

An attempt was made to study the combination treatment of chemical preservative and pasteurization treatment, to preserve the custard apple pulp in deep freezer for a period of three months. The results revealed that chemical constituents of the pulp viz., total soluble solids, reducing sugar, total sugars and non enzymatic browning were found to increased marginally from 26.54 to 27.33 per cent, 15.73 to 15.99 per cent, 19.06 to 19.40 and 1.18 to 1.63 and 0.087 to 0.129 respectively, whereas ascorbic acid, titratable acidity, non-reducing sugar, decreased from 9.38 to 7.95 mg per 100g, 0.69 to 0.50 per cent, 3.11 to 3.02 per cent, 41.17 to 36.32 and 5.35 to 5.04 respectively, during the storage period of 90 days. However, non significant differences were noticed in total sugar throughout the storage period, for acidity at 30, 60 and 90 days and for non reducing sugar at 30 and 90 days after storage. During storage period of 90 days, the mean organoleptic scores decreased from an 8.14 to 5.91 for overall acceptability. There was marginal increase in microbial load (TBC) in custard apple pulp during storage, but it did not affect the wholesomeness of the product up to 90 days of storage.
