The appropriate parameters to produce nectar of tree tomato (Solanum betaceaum Cav.), with a greater retention on the content of ascorbic acid, phenolic compounds, total carotenoids a Ingeniero en Industrias Alimentarias. Facultad de Industrias Alimentarias, Universidad Nacional Agraria La Molina, Avenida La Molina, Lima 15024, Perú, drojas@lamolina.edu.pe b Profesor Principal del Departamento de Ingeniería de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional Agraria La Molina, Lima Perú. c Profesor Asociado del Departamento de Tecnología de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional Agraria La Molina, Lima Perú. Determinación de la máxima retención de compuestos bioactivos y capacidad antioxidante en el néctar... 175 Rev Soc Quím Perú. 83(2) 2017 and antioxidant capacity that are present in the raw material, were established. The content of bioactive compounds in the tree tomato pulp was determined: total carotenoids with 4,27 mg β-carotene/100g, vitamin C with 28,83 mg ascorbic acid/ 100g, phenolic compounds with 100,55 mg AGE/100g and the antioxidant capacity with 3,3172 μmol trolox/g measured by the DPPH method and 4,6551 μmol trolox/g measured by the ABTS method. A greater retention on the bioactive compounds and antioxidant capacity on the tree tomato nectar was obtained at a pH of 3,33, °Brix of 13, dilution water:pulp of 1:2,5 and a pasteurization temperature of 99,5°C for 1 minute, finding on it a content of 1,68 mg β-carotene/100g, vitamin C of 11,45 mg de ascorbic acid/100g, phenolic compounds of de 32,96 mg AGE/100g y the antioxidant capacity of de 1,3803 μmol trolox/g measured by the DPPH method and 2,0006 μmol trolox/g measured by the ABTS method.
