Abstract EN
The objective of this study was to evaluate the quality of some newlybred Sudanese tomato genotypes at the National Institute for Promotion of Horticultural Exports- Gezira University, to identify their suitability for paste production, these genotypes included: Juvenile, Top -1, Line -4, and Line -2.
Line 4 scored the highest paste yield (17.5 ton/ha) followed by Juvenile (14.35 ton/ha), Top -1 (11.3 ton/ha) and Peto 86 (7.92 ton/ha).
The proximate chemical analysis revealed that the moisture content of the different fresh tomato samples ranged between 92% and 94%, and notable differences were found in protein and ash contents.
The paste samples differed significantly in pH, acidity, total soluble solids and vitamin C contents.
Moreover, all paste samples contained appreciable amounts of calcium, phosphorous, potassium and sodium.
The microbiological analyses revealed absence of yeast and moulds in all paste samples, while the paste prepared from Juvenile tomato genotype contained high total viable microbial cells.
The sensory evaluation of various paste samples showed significant differences in their texture and overall quality.
