4. Conclusions
In conclusion, RBP showed superior nutritional quality in comparison
to vegetable proteins, but the biological availability of RBP
is still lower than that of animal protein sources; however, there is
a growing need to replace animal protein with vegetable protein,
because of the increased cost and limited supply of animal proteins.
Since rice bran is an economical nutritional protein source
and is available in large quantities, its protein isolates could be
used as new protein sources of nutritional and economic value
