Abstract
A common conversion factor of 6.25 has been used worldwide to estimate
crude protein content. However, many researchers especially Jones (1931)
has extensively researched and did not agree with using the same factor
for every food ingredient as it resulted in misleading estimation of
crude protein content. ICMR/NIN and FAO/WHO/UNU recommendations over
decades for protein and amino acid requirements using various techniques
are used to state Estimated Average Requirement (EAR) and Recommended
Daily Allowance (RDA) as accurate as possible. In the present
manuscript, nitrogen: protein conversion factor has been reworked using
NDpCal%.
