The present research work aimed to develop juice based on Vangueria infausta pulp powder and to determine the preliminary chemical and nutritional composition. The juice production was carried out by the thermal processing method followed by blanching at a temperature of 90 °C, after pulping and lyophilization of the fresh fruit of Vangueria infausta. The chemical and nutritional composition in mineral content was determined by gravimetric methods and spectrophotometry of ame, moisture, fats, ash, total ber by gravimetric methods and prospection of the phytochemical composition, including antioxidant activity, by colorimetric methods, using molecular absorption spectrophotometer and chemical reagents. From the chemical and nutritional composition, it was possible to quantify the crude ber present in 7.95%, ash in 7.77%, fats 0.5% w/p, the minerals Fe 10.59 (mg/100g), Ca 0.16 (mg/100g), Na 139.06 (mg/100g), K 1424.47 (mg/100g) the most expressive and P with 0.060% (m/m) was the least expressive of the sample, alkaloids, compounds phenolics and avonoids the antioxidant activity is present in 15%, and the presence of phenolic compounds in this fruit are responsible for this activity. This study aims to evaluate the chemical-nutritional composition of the pulp of the maphilwa fruit (Vangueira infausta) used in the production of juice, in order to value and encourage the consumption of unconventional foods (based on native plants) in communities.
