Abstract
The objective of this work was the elaboration and physicochemical characterization of traditional mixed prebiotic jellies of jabuticaba and acerola. In the case of F2 (50% acerola/50% jabuticaba), F3 (25% acerola/75% jabuticaba), F4 (100% jabuticaba) and F5 (100% acerola) with 1.0% pectin, 0.1% potassium benzoate, 3% inulin and 40% sucrose. The ingredients were mixed and the mixtures were concentrated to total soluble solids (TSS) between 65 and 68 °Brix. The jellies from pulps and blends of acerola and jabuticaba presented acidity levels varying from 0.77% to 0.80%. The jellies F1 and F5, which have the highest concentration of acerola pulp in the formulation, presented TSS of 65 °Brix. It has been found that as the percentage of jaboticaba pulp increased in the jellies, the total polyphenol content decreased from 405.43 to 135.75 GAEg/100 g. It is observed that, as the proportion of acerola pulp in the blends increased, the vitamin C content also increased, especially in pure acerola pulp with 3,704.50 mg/100 g. Total carotenoids ranged from 1.63 to 4.62 mg/100 g. F4 jelly, obtained from jabuticaba pulp and peel, presented the highest values for texture parameters, except for cohesiveness. It was observed that the contents of antioxidant compounds favored a nutritional profile to the jellies. Regarding the functional profile, the product complies with the current Brazilian legislation because it contains inulin, in addition to the presence of antioxidants.
