A NEW PROCESS TECHNOLOGY FOR THE PRODUCTION OF VAVNASPATI LIKE NUTRITIOUS MODIFIED FAT OF DESIRED PUFA(POLY UNSATURATED FATTY ACID)LEVEL AND VARIED.GLYCERIDE COMPOSITION,DIRECTLY FROM COMMERCIALLY REFINED OILS AND FATS INTERESTERIFICATION UNDER THE CATALYTIC INFLUENCE OF SODIUM METHYLATE POWDER

摘要

A process of interesterification of glyceride oils starting directly from commercially refined oils and fats to produce modified fat having randomly rearranged glyceride composition, rich in PUFA (poly unsaturated Fatty Acid) content, free from trans isomer, having desired plasticity and presence of EFA (Essential Fatty Acid) as required for better nutrition which comprises pre treating the oil with dill solutions of NaOH till the FFA (Free Fatty Acid) content of the oil becomes neutralized, drying the oil by heating under vacuum and adding 0.05-0.1% NaOCH3 on the dried oil at required temperature under vacuum with continuous stirring till the completion of rearrangement reaction and subsequently destroying the catalyst by means of dill phosphoric acid and washing several times with hot water till it is free from catalyst or soap and the randomized mass is heated under vacuum till it is dry.
