Common carp protein is characterized by a high content of essential aminoacids, compared to the standard protein established by the FAO, exceeding values in the case of Met + Cys and Val (Table 2) in fresh carp, having Leu as the limiting aminoacid and presenting a "limiting aminoacid" index (or chemical index) of 82.27; this index is a basic parameter used for the evaluation of the nutritional value of a food, which refers to the minor content of an essential aminoacid with regard to a given standard protein, called the "limiting aminoacid." In this study, the essential aminoacids in the sample in freezing without EC decreased, only maintaining Val as the excess aminoacid and having Lys as the limiting aminoacid.

Milk proteins especially caseins and lactoserum (whey) proteins are nutritionally very important because these proteins contain all essential aminoacids in optimal amounts and are the most vital source of bioactive peptides(Cozma et al., 2011).Whey, a by-product from the curd and cheese manufacturing, was once considered a waste product(Pelmus et al., 2012).
