What Is a Chemical Score

chemical score A measure of protein quality based on chemical analysis of its amino acid composition.

What is a good chemical score?

It is defined by comparing the essential amino acids ratio of the studied protein with the reference protein of the FAO1, which is considered as “ideal”: it contains all essential amino acids in the minimum necessary proportion for the body. Consequently its chemical score has been fixed at 1002.

How do you find a chemical score?

One method for assessing dietary protein quality is by determining a diet’s chemical score, ie, the ratio of a gram of the limiting amino acid in a test diet to the same amount of the corresponding amino acid in a reference diet (eg, whole-egg protein) multiplied by 100.
