One of the major by-products of the rice bran oil refining industry is rice bran gums (RBG). It is considered a waste product because it hardly fetches any revenue. However, the major component of RBG is phospholipids and the demand for phospholipids has seen steep rise, especially for its use in COVID-19 vaccines. Though soyabean and egg lecithin are the major sources of phospholipids, industries are striving for newer sources. RBG can be an alternative source. Presence of bran fines, darker colour, and relatively low quantity of phosphatidylcholine (PC) in crude RBG, are the major hindrances for its widespread applications. The primary question was whether the crude RBG can be valorized to be a source of phospholipids for use in food, cosmetics and pharmaceutical industries. Present work focuses on bleaching of crude RBG and preparation of powdered rice bran lecithin. Appreciable colour reduction was observed with sodium chlorite as bleaching agent. Furthermore, PC-enrichment of RBG was attempted for enhanced applicability in nutraceutical and pharmaceutical products. HPLC analysis showed PC enrichment of more than 50% under specific conditions of solvent used, solid-to-solvent ratio, time, and temperature. These observations are the first of its kind with regard to RBG. [ABSTRACT FROM AUTHOR] |
