Quality Evaluation of Some Jackfruit Genotypes of Eastern and North Eastern India

Abstract

Jackfruit is one of the indigenous and underutilized fruit of Rain Forests of India. Naturally Eastern and North Eastern India have the rich genetic base of jackfruit with wide genetic variability of plant growth, fruiting behaviour, fruit physical and quality attributes of fruit. Present research was aimed to study the quality attributes of some jackfruit genotypes of Eastern and North Eastern India. The properly mature fruits of sixteen selected jackfruit genotypes (soft type) of different locations of Eastern and North Eastern states were collected. Quality parameters like total soluble solids (TSS), titratable acidity, total sugar, reducing sugar, ascorbic acid, carotene, dry matter content etc. were evaluated. Sensory evaluation was also carried out to judge the acceptance of the selected jackfruit genotypes. TSS of the bulbs of different jackfruit genotypes ranged from 17.35 to 28.12 °Brix while titratable acidity from 0.42 to 0.93 %. Maximum total sugar and reducing sugar were 17.71 and 8.03 % respectively. A range of ascorbic acid content of fruit pulp of different jackfruit genotypes from 5.24 to 10.12 mg/100g was recorded while it was from 311.2 to 496.7 pg/100g in p-carotene content. The jackfruit selections collected from North Bengal, lower Assam and Tripura were superior with respect to different quality parameters and sensory analysis.
