Original sentence: Egg protein scored the highest number of 100 to serve as a measuring stick.Further testing validated, the biological value of protein for whole eggs is 100 and 104 for whey.The now accepted method tested in humans for protein utilization is biological value of protein
Edited sentence: Further methods of refining whey protein through the use of isolates, microfiltration, and ion exchange supposedly have raised the biological value of whey protein up to 159 on the 100 egg scale.However this was incorrect and most likely due to a confusion between chemical score and biological value.Later the score was changed to express the percent of utilized protein and egg protein's score was recalculated to 93.7.Originally when the method was first devised and tested in humans egg protein scored the highest so it was given the arbitrary number of 100 to serve as a measuring stick.Some confusion has arisen due to the fact that many websites and publications still use the 100 egg scale and not the since adjusted scale which places the Eggs' biological value at 93.7.This confusion has also been furthered by the continuing use of the older scales in some scientific publications
