Trivia on Soya Bean Protein

Monday 17 September 2012

Protein Digestibility Corrected Amino Acid Score (PDCAAS) is a method of evaluating the protein quality based on
  • the amino acid requirements of humans; and 
  • our ability to digest it. 

The closer the amino acid profile of a food protein in resembling the structural profile of the human protein, the higher will be the nutritional value.

Since 1993, this method has been recognized by World Health Organization (WHO) as being the best way to evaluate the quality of a food protein. The ratings for PDCAAS range from "1" = highest score to "0" = lowest score. The table below shows the ratings of selected food:

0.91 Soya Bean
0.73 Vegetables
0.54 Wheat
0.52 Peanuts

Soya bean is the richest in nutrients among all plant proteins. Its nutritional value can be as high as that of animal protein. In fact, the genetic structure of soya bean is the closest to that of human amino acids. In other words, it provides a full spectrum of the "essential amino acids" needed by the human body, making it an ideal source of "premium grade protein".
