Abstract


The purpose of this research was to establish physico-chemical characterization of Dovyalis hybrid fruits (MIA 25359). Samples of 30 fruits were characterized by evaluation of fruit and seed weight, length and width, percentage and number of seeds per fruit, peel and pulp percentage, total soluble solids (TSS), titratable acidity (TA), TSS/TA, fresh/ dry weight ratio, and maturity index. Dovyalis fruit showed good physical quality for commercial purposes with an average of 90.5% pulp, 9.0 % skin, and 1% seed. Sugar content (TSS) ranged from 14.34 to 16.28, pH 2.44 to 3.63, and TA of 3.85% to 4.76%. Fruit color values for the luminosity (L) of Dovyalis accession (MIA 25359) ranged from 33.06 to 43.59. The values for a* and b* ranged from 15.50 to 22.16 and 10.0 to 27.28, respectively. Fresh/dry weight ratio ranged from 0.17 to 0.20 and maturity index from 3.22 to 4.03.
