EFFECT OF HOMOGENIZATION PRESSURE ON SURFACE FAT CONTENT IN SPRAY-DRIED EMULSIONS STABILIZED WITH MILK PROTEINS
Journal Title: Żywność. Nauka. Technologia. Jakość - Year 2010, Vol 17, Issue 6
Abstract
The objective of this study was to analyze the effect of homogenization pressure on the content of surface fat in spray-dried o/w emulsions stabilized with milk proteins. There were analyzed emulsions containing a protein component (whey protein isolate (min. 95 % protein) or sodium caseinate), a carbohydrate component (maltodextrin DE 28 or trehalose), and fat (rapeseed oil); the ratio of those three components was 30:40:30. The content of free fat on the surface of powder particles decreased with the increasing pressure homogenization of emulsions. Additionally, contingent on the type of carbohydrate and protein component, this content ranged from 4.31 to 7.46 g / 100 g of powder at a homogenization pressure of 25 MPa; 2.67 - 3.88 g / 100 g of powder at a homogenization pressure of 45 MPa; and 1.61 - 2.33 g / 100 g of powder at a homogenization pressure of 65 MPa. The powdered emulsions were fine powders showing poor flowability, but can be easily dispersed in water.
