Among the fruits of the Cerrado stands 'Pequi'(Caryocar brasiliense Camb.), which consists of approximately 80% of peel, but is ignored, however has potential for use in various applications. The objective of this study was to evaluate the influence of variables citric acid concentration, temperature and extraction time on yield and esterification degree of pectin extracted from the pequi peel, and compares it with commercial citrus pectin applied in the light formulation jam. It was obtained yields of pectin from 14.89 and 55.86 g.100g(-1). Pectin derived from peel pequi was characterized by having a low esterification degree (11.79 to 48.07%). The light jam made from the pectin extracted from the pequi peel at the temperature of 84 degrees C for 92 minutes in the presence of 2% citric acid, obtained good acceptance by the tasters, reaching mean scores above7.0, differing from jam produced with commercial citrus pectin in appearance only. It follows that it is possible to use the pectin from pequi peel as an ingredient for formulation of mango light jam.
