Proximate Composition and Preservation by Combined Methods of Chupandia (Cyrtocarpa procera) Pulp

Marco Vinicio Ramirez-Mares, Claudia Villanueva-Canongo and Carlos Guillermo Hernandez

Abstract:
The Cyrtocarpa procera pulp was analysed for proximate composition and the effects of combining techniques such as addition of Potassium Sorbate (KS), modification of water activity (aw) and Heat treatment (H) on the microbiological shelf life of C. procera pulp were evaluated during 100 days of storage at 25oC. The experiment was laid out in a randomized 23 factorial with three replications. The pulps were periodically analyzed for UFC/g of yeast and moulds, pH, aw and total soluble solids (oBrix)). The values (%) of proximate analyses were: moisture 83.62, protein 1.61, fat 0.30, ash 0.68, crude fiber 0.38 and carbohydrate 13.41. Metabolizable energy 62.78 kcal/100 g. The addition of 400 ppm KS (p<0.0001) and H (60-65oC for 3 min, p<0.05) can extend the stability of the pulp up to 100 days at ambient temperature (25oC) without deterioration in quality. The reliability of a model developed to predict the aw 25oC as a function of pH and oBrix, was assessed through validation with the C. procera pulp results, the predictive performance of the model can be considered acceptable. Results indicate that combining heat treatment with addition of KS can be used to extend the shelf life of C. procera pulp kept at ambient temperature and that the low carbohydrate and gross energy values may qualify C. procera pulp as a good component in food formulation for the obese and diabetics.
