Abstract
This work aimed to study the effect of citric acid and passion fruit albedo concentrations and pulp/sugar ratio in optimizing of jam production process of Pouteria cf. gardneriana Radlk (guapeva fruit) and evaluating the nutritional characteristics and functional properties of the developed jams. A factorial design 23 with 11 assays was used, considering citric acid concentration, pulp/sugar ratio, and albedo concentration as independent variables. Formulations containing a 50/50 pulp/sugar ratio proved to be excellent for quality parameters, the potential of phenolic compounds, antioxidants, and sensory properties. The formulation indicated as most desirable was the one containing a 40/60 sugar/pulp ratio. Guapeva proved to be a good alternative for jam production because even after thermal processing, it was possible to obtain jams rich in Vitamin C, phenolic compounds, and antioxidant potential.
