FPH (2.5%, 5%, 10%, and 15% degree of hydrolysis [DH]) were made from isolated proteins from headed and gutted BW with Alcalase 2.4 L. The properties of dried BW mince and protein isolate compared to 4 reference proteins (soy and milk protein) were studied: color, solubility, water-holding capacity (WHC), oil-binding capacity (OBC), emulsion capacity (EC), and emulsion stability (ES). The angiotensin I-converting enzyme (ACE) inhibitory activities of the soluble fraction of BW powders were also investigated. Furthermore, the products were characterized by analyzing their chemical composition. Chemical composition, solubility, OBC, and EC of the BW powders was significantly (<em>P<\/em>\u00a0&lt; 0.05) different with different DH, while color, ES, and WHC were not significantly (<em>P<\/em>\u00a0> 0.05) different. Salt content of the FPH was high (4% to 19%) and increased with increased DH. Protein solubility varied from 10% to 70% and increased with increased DH. WHC of the FPH was around 97% and was higher than that of all the reference proteins tested. OBC decreased with increased DH (from 3.5 to 2.1 g oil\/g protein) and was higher than OBC of the soy and milk proteins (1.6 to 1.9 g oil\/g protein). EC of FPH was similar or lower than the reference proteins. ES of FPH (60% to 90%) was similar to or lower than soy and whey proteins (60% to 98%) but higher than casein (20%). ACE inhibition activity increased as DH was increased.<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1111\/j.1750-3841.2010.01877.x\">Hlekkur a\u00f0 grein<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Functional and biochemical properties of fish protein hydrolysates (FPH) from blue whiting (BW) were studied.
