Abstract
The Plant Genetic Resource Bank Buzau, Romania, holds a germplasm collection of over 2300 tomato genotypes that have been systematized according to specific directions of use: fresh consumption (56%), processing (26%) and mixed (18%). The genotypes suitable for industrialization have been classified according to the purpose of use, both for fresh juice, tomato paste and ketchup.
Of these, 3% are suitable for fresh tomato juice of superior nutritional and organoleptic quality.
The present work aims to study the nutritional profile and chemical composition of tomato juice obtained from the identified group of tomato genotypes with specific use direction.
Four genotypes cultivated in two cropping systems, both in open field and in protected areas, were evaluated, comparing the quality of fresh tomato juice from the two growing environments.
In order to determine the quality of the tomato juice, bio-chemical analyses were carried out to determine the dry matter content, citric acid content, soluble matter content, ascorbic acid and lycopene content.
The tomato juice obtained from genotype L1996F44 had a balanced sugar-acidity ratio and homogeneity in terms of consistency, unlike the other lines, thus meeting the necessary qualities specific to this direction of use.
The genotype has been proposed for approval and patenting.
