Estudio Comparativo del Potencial Nutritivo de Dos Variedades de Tomate de Arbol (Solanum betaceum Cav.) Deshidratado por Microondas a Tres Potencias

Abstract

"This rescarch work carried out a comparative study of nutritional potential of two varieties of trec tomato (Solamun betaceum Cax.), taking as an indicator of efficiency of the process of dehydration, the concentration of anthocyanins, carotenoids an vitamin C whith the varicty to minimize the loss of nutrients. In the nutritional parameters obtained is a marked diference in the dehydrated there is less water content in the range 14.58% orange giants and the giant purple varicty 14.28% thus ensuring optimal preservation, the ash content increases in the Orange giant purple giant of 5.93% being so fresh to 8.00% in the dehydrated and fresco 5.82% to 6.93% in drid as appropriate in this is that the mineral elements are found in greater concentration within the fiber case the concentration of solutes in dehydrated, this is 8.79% higher in the giant orange and 8.29% in the purple giant, cqually true of the protein with a valuc of 11.18% for the dehydrated orange giant and 8.93% in the dwelling giant, the sugar percentage was 34.92% and 33.46% in the dehydrated as appropriate due to thcir concentration. To determine the optimal drying method was applied. 1o 3 power microwave 70, 140 and 210 W tree tomatoes in giant orange variety was dried at 70 minutes and the giant purple range S0 minutes presenting a concentration of 107.23mg/ 1003 of carotenes and 78.34 mg/100g of vitamin C in tomato giant Orange and a concentration of 250.43 mg / 1003, 99.50 mg/100g anthocyanins and vitamin C in the giant purple variety, it follows that the power 210 W loss of anthocyanins, carotenoids and vitamin C is higher. We also carried out microbiological analysis for tree tomato fresh and dricd optimum observed in the fresh absence of fungi and yeasts in the giant orange variety and the giant purple variety there is no presence of fungi and yeasts for 10 UPC/gram dehydrated in the absence existed two varictics of fungi and yeast. Thus, consumption of tomato tree has medicinal properties, so it is recommended that studies on this research."
