Assessment of nutrient content of tomato hybrids for processing

Abstract

We have tested the refraction of 6 cultivars of open-field tomatoes. In our work, we have tested the nutritional values of tomato cultivars harvested at different times. Our aim was to answer the question as to which cultivar fulfils the requirements for processing under given circumstances. During harvest time, we also measured the ratio of yellow and red pigments. The trial was conducted in Kecskemét, Hungary, on the trial field of NAIK ZÖKO, in open-field conditions. The refraction measurement was done on weighted tomato, which was then ground to juice and then measured on a tabletop refractometer. The 6 tested cultivars Brix% were measured at 5 different harvest dates, and then the average refraction of the harvest was analysed. The most suitable cultivar for processing was found to be Solerosso.
