Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type:	Student Project Report
Additional Information:	<p align="justify">GLV could be helpful to suggest using leafy vegetables as a part of daily meal. To achieve this goal, nutritional awareness on the importance of these GLV is warranted among various communities in the country. The present study clearly demonstrates that PC in mixed micelles suppresses the intestinal uptake, accumulation and conversion of newly absorbed β-carotene in to retinol, while lysoPC enhances β-carotene level and conversion efficiency of retinol by activating the dioxygenase. Thus, the present results suggest that the hydrolysis of PC to lysoPC is an important step for the intestinal uptake of β-carotene solubilized in mixed micelles and that dietary lysoPC modify the bioavailability of β-carotene. The mechanism of these effects of phospholipids in mixed micelles on the intestinal uptake of β-carotene and, in particular, its relationship to intestinal lipid metabolism deserves further study.</p>
