Abstract

Modification of pH and NaCl concentration changed the physicochemical properties of sarcoplasmic proteins SP from jumbo squid mantle and consequently their functional properties. Better results of emulsifying activity index EAI and foam capacity FC were exhibited at pH 11 in NaCl absence due to higher solubility. But better emulsifying stability index ESI was obtained at pH 11 in 0.5 M NaCl, while, foaming stability FS was better at pH near to isoelectric point pI. These results suggest that SP from jumbo squid may be a promising ingredient, whose functional properties can be manipulated by changing pH and NaCl concentration.
