ABSTRACT

En este trabajo se evaluó el efecto del consumo del jugo de tomate de árbol (Cyphomandra betacea) sobre parámetros nutricionales y bioquímicos en 54 voluntarios (44 mujeres y 10 hombres) con edades 45±8 años de Ecuador. Al inicio se les realizó una evaluación nutricional y bioquímica, luego se les invitó a consumir el jugo (100g de fruto en 150 ml de agua) diariamente durante 6 semanas. Finalizado este tiempo, se procedió a realizar la evaluación nutricional y bioquímica nuevamente. La evaluación nutricional determinó 67% de obesidad abdominal. Disminuyendo a 53% después del consumo del jugo de tomate de árbol. El 87% de los voluntarios antes del tratamiento, mostraron hipercolesterolemia; 40,7% y 46,3% tenían los triglicéridos y el LDL elevados y 18,5% valores de glucosa entre 98-130mg/dL. Valores que disminuyeron significativamente en este grupo después de la toma del jugo En general, tanto en voluntarios con y sin sobrepeso se observó disminución significativa de colesterol total, LDL y glucosa; sin cambios significativos en los valores de HDL. El consumo del jugo no afectó la actividad de las enzimas alanina-aminotransferasa ni aspartato-aminotransferasa, tampoco las concentraciones de creatinina, urea y ácido úrico; ni la presión arterial, demostrando que no afecta la función hepática ni renal. Estos resultados indican que el consumo del jugo de tomate de árbol, durante seis semanas, parece ejercer un efecto hipolipemiante y moduladora en el metabolismo de la glucosa y colocan a C betacea como uno de los frutos andinos con alto potencial nutraceutico. Sin embargo, estos aspectos deben ser investigados con más detalles(AU)


In this work the effect of consumption of tree tomato juice (Cyphomandra betacea) was evaluated on nutritional and biochemical parameters in 54 volunteers (44 women and 10 men) aged 45 ± 8 years-Ecuador. A nutritional and biochemical evaluation was performed in volunteers; then they were invited to drink tree tomato juice (100g of fruit in 150 ml of water) daily for 6 weeks. Finished these 6 weeks, volunteers were nutritional and biochemical evaluated again. 67% abdominal obesity was found, decreasing at 53% after drinking the established dosage of juice. 87% of the volunteers before treatment, showed hypercholesterolemia, 40.7% and 46.3% had hypertriglyceridemia and elevated LDL, respectively and 18.5% glucose concentrations between 98-130 mg/dL. These values decrease significantly in this group after drinking tomato juice. In general, Total Cholesterol, LDL and glucose concentrations decrease significantly after drinking tree tomato juice in all the voluntaries with or without overweight. There is no change in HDL concentrations. The consumption of tree tomato juice did not affect the activity of alanine aminotransferase or aspartate aminotransferase enzymes either creatinine, urea and uric acid concentrations, neither blood pressure suggesting that does not affect renal or liver function. These results indicate that consumption of tree tomato juice for six weeks appears to have a lipid-lowering and modulating effect on glucose metabolism, suggesting C betacea as one of the high Andean fruits nutraceutical potential. However, this issue should be investigated in more detail(AU)

ABSTRACT

El tomate de árbol (Cyphomandra betacea) es apreciado por sus cualidades nutritivas y ser fuente de compuestos antioxidantes, calcio, fósforo, potasio y hierro, azúcares, ácidos orgánicos, pectinas y flavonoides. En este estudio se determinaron parámetros físicos (peso, tamaño, fuerza compresión, humedad) y químicos (°Brix, acidez titulable, pH, proteína, fibra dietaria, cenizas, minerales y bioaccesibilidad de minerales, pectina, compuestos antioxidantes) del fruto procedente del Estado Aragua, Venezuela, como una contribución para incentivar y diversificar su consumo. La caracterización reflejó que los frutos estaban en estado de madurez para su consumo (°Brix 10,51, pH 3,5, acidez 0,02 g/100 ml y fuerza de compresión 4,32 Kgf/cm2), con rendimiento de pulpa del 74%. Los resultados del análisis de la pulpa madura reflejan un aporte de 30 Kcal/100g, fibra dietaria (4,10g/100g) y valores de fósforo, calcio, magnesio potasio y hierro de 331,32; 21,25; 21,18; 17,03; 7,44 mg/100g respectivamente. Se obtuvo 6,71 y 1,86 % de bioaccesibilidad para calcio y hierro. La pectina extraída (1,00 g/100g) resultó ser de alto metoxilo y alto grado de esterificación. La capacidad antioxidante de la pulpa madura (EC50 de 165 g /g DPPH y poder reductor de 0,07 mmol Fe +2/100g) pudiera atribuirse a la presencia de ácido ascórbico (23,32 mg/100g), licopeno (1,22 mg/100g), compuestos fenólicos (1,39 mg EAG/ g), antocianinas (0,29 mg cianidina/g) y taninos (0,40 mg catequina/ 100g). Los resultados obtenidos pueden ser utilizados para promover los beneficios sobre la salud y sugerir su uso como ingrediente funcional en el desarrollo de productos.


Physical, chemical and bioactive compounds of tree tomato (Cyphomandra betacea). Tree tomato (Cyphomandra betacea) is appreciated for its excellent nutritional qualities, being considered a good source of antioxidants compounds, calcium, phosphorus, potassium and iron, sugars, organic acids, pectins and flavonoids. In this study, were evaluated physical parameters (weight, size, compression strength and humidity) and chemical (°Brix, titratable acidity, pH, protein, dietary fiber, ash, minerals and their bioaccesibility, pectin, antioxidants compounds) of the fruit from the Aragua State, Venezuela, as a contribution to stimulate and diversify the consumption of the tree tomato. The characterization showed that the fruits were at the ripening stage for consumption (°Brix 10.51, pH 3.5, acidity 0.02 g/100ml and 4.32 Kgf/cm2 compression strength) gave a yield of 74% pulp. The analytical results of the ripped pulp showed a content of 30 Kcal/100g, dietary fiber (4.10g/100g), and minerals such as phosphorous, calcium, magnesium, potassium and iron (331.32, 21.25, 21.18, 17.03 and 7.44 mg/100g, respectively). Bioaccesibility values of 6.71 and 1.86% were reported for calcium and iron. The extracted pectin (1.00 g/100g) was classified as high methoxyl with high degree of esterification. The antioxidant capacity of the ripped pulp (EC50 of 165.00 g /g DPPH and reducing power of 0.07 mmol Fe +2/100g), could be attributed to the presence of ascorbic acid (23.32 mg/100g), lycopene (1.22 mg/100 g), and phenolic compounds (1.39 mg GAE/g), anthocyanins (0.29 mg cyanidin/ g) and tannins (0.40 mg catechin/100g).The results obtained encourage the nutritional benefits and suggest applications as a functional ingredient in food product development.
