Amino acid content and amino acid scores (AAS) in fermented
milk products prepared with 2% dibs in fresh stage
As shown in Table 6, most amino acids occur in fermented milk
products but not in different relative percentages. It could be
gathered that the total amino acids content in fermented milk
products with 2% dibs are higher than those in the rest of products.
Also, it will be seen that sulfur amino acid content attained
the least concentration as compared with the rest
amino acids. Moreover, it is clear that lysine and leucine+isoleucine
are the predominant amino acids followed by alanine.
In this connection, it was of interest to notice that all amino
acids except cysteine and cystine were detected in biogarde.
Undoubtedly, the absence of some amino acids may be due
to the decomposition of these acids by microorganisms, (Abd
El-Tawab, 2009). In this connection, Noeman and Shalaby
(1992) reported that aspartic acid, cystine and ornithine were
not detected in acidophilus milk, while in zabady only cystine
was absent. Additionally, it was evident from the tabulated
data that zabady with 2% dibs and biogarde with dibs possessed
the highest content of essential amino acids, being
22.58 and 21.93 g/100 g, respectively as compared with the controls.
However, Table 6 represents the amino acid scores (AAS)of different cultured milk products, it could be considered that
zabady with 2% dibs and biogarde with 2% dibs are
good sources of lysine, histidine, threonine and leucine +
Isoleucine.
