Abstract

Techno-economical feasibility up gradation of fruit processing is underlined on the basis of yield and quality of finished food products by involvement of biotechnology. It has been postulated that the most effective enzymatic liquefaction of fruit mash is result of synergistic action governed by combination of pectinase quotients. The desired yield of fruit juice coupled with clarity of juice, reduced waste index and easiness in separation of seeds from pulp of unconventional fruits such as custard apple (Annona squamosa), and ramphal (Annona reticulata L.) against conventional method. Enzymatic liquefaction exhibited higher per cent yield (74% transmittance T.) of sparkling clear juice i.e. up to and overall improvement in quality. Increase in per cent yield of juice by 25 per cent over that of conventional method is an outstanding achievement of enzyme processing technology.

Abstract

The machine main frame had dimensions 2000 mm × 1250 mm × 1000 mm, with a approximate cost of Rs. 45,000. The performance parameters such as actual capacity, grading efficiency of each grade, overall grading efficiency, damage loss and peel loss were studied in this work. The operating speed of the grader was maintained at constant speed 16 revolutions. The maximum grading efficiency of 96 and 62.3 per cent was found in onion and potato grading, respectively. The cost of the mechanical grading obtained was Rs. 30 per tonne. The ratio of cost for manual to mechanical grading worked out to be 12.45:1. During the performance test only peel loss was observed in onion grading while in case of potato grading more damage occurred. Therefore, this grading is only suitable for onion grading.
