General description

Ovalbumin is the major constituent of egg white protein produced in the hen′s oviduct, particularly in the magnum tissue.[1] This glycoprotein represents about 54% of the total proteins of egg albumin.[2] Ovalbumin is a member of the serine protease inhibitor (SERPIN) family.[1]

Application

Albumin hydrolysate has been used:
  • to study its effects on the content and profile of volatile aroma compounds of various food products[3]
  • to determine the degree of interaction of free or included form of hydroxycinnamic and chlorogenic acids (CHAs) with egg ovalbumin and to analyze the stability of interactions during proteolysis[4]
  • as a supplement in various food types to evaluate their bioaccessibility after food processing as well as after in vitro enzymatic hydrolysis[5]

In a rather unusual application, albumin hydrolysate enhanced ethanol production during fermentation by Saccharomyces sake (sake yeast). In media supplemented with albumin hydrolysate, final alcohol concentration was 60% higher than without supplementation. The effect is believed to be due to enhanced alcohol tolerance of cells grown in supplemented medium.[6]

Biochem/physiol Actions

Ovalbumin contributes to the formation of egg white.[1] It elicits various biological activities, such as antihypertensive, anticancer, antimicrobial, antioxidant, and immune-modulation.[7]
