Sneh D. Bhandari, Ph.D., is the Director of Chemistry Research at Silliker Inc. (now part of Merieux NutriSciences) and has been part of the Silliker for over twenty five years. He did his doctorate in Nutritional Biochemistry. He has been an UNESCO postdoctoral research associate at University of Arizona HSC. His earlier research was on different aspects of nutritional biochemistry. He performed research in folate metabolism at LSUMC and University of Florida before moving to the Silliker. He has developed and validated and verified various methods in food and dietary supplements analyses including protein quality evaluation.
He is actively involved with AOAC and AOCS for a long time and is currently a member of various technical committees, expert Review Panels and Working Groups. He has also served on AOAC Methods Board. He is the Fellow of AOAC International. Dr. Bhandari is the author of numerous refereed articles and book chapters and presentations at the professional meetings.
The need of accurate estimations of protein quantity and quality has gained further importance because of a new trend of development of protein enhanced products. Kjeldahl and combustion (Dumas) methods are widely accepted for total protein estimation but they lack selectivity and can’t rule out adulteration. Protein digestibility-corrected amino acid score (PDCAAS) is one of recognized option to evaluate protein’s quality. The method requires amino acid analysis to determine amino acid score and true digestibility value. Other options of protein quality evaluation will be reviewed.
