Abstract

MATSUURA, FERNANDO CÉSAR AKIRA URBANO  and  ROLIM, RENATA BERBERT. Evaluation of acerola juice additions to pineapple juice for a high vitamin C blend. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.138-141. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452002000100030.

The objective of this study was to enrich in vitamin C the integral pasteurized pineapple juice (PJ), by addition of different amounts of integral pasteurized acerola juice ¾ AJ (5,10,15 and 20 %), to get a blend of these juices and a final product with the same sensorial characteristics as the PJ. The sources used were commercial pulps. Sensorial evaluation was carried out for colour, odour, consistence and flavour attributes, by using the multiple comparison test. Physical-chemical analyses of vitamin C (ascorbic acid), total soluble solids, pH and total titrable acidity were also done. The results of the sensorial analyses showed no significant difference (p>0,05) between the PJ (pattern) and its blends with AJ at 5 and 10%, for all attributes tested. The addition of AJ at 10% resulted in final product with about five times the vitamin C content of PJ.

Keywords : fruit; product; ascorbic acid.
