Conclusions
Endogenous proteases in squid byproducts can produce hydrolysates
with useful properties. The yield was higher at
pH 7.0 than pH 5.0. The effects of pH on the DH, amino acid
profile, and hydrophobicity of jumbo squid byproduct hydrolysates
were determined. Spectrophotometric and morphological
analyses are useful for characterizing jumbo squid
byproduct protein hydrolysates. This biophysical characterization
enhances the understanding of the molecular, and,
consequently, physiochemical properties of these hydrolysates
to establish their proper use. We are currently investigating
uses for these hydrolysates in both human and shrimp culture
applications.
