Structures And Properties Of Stabilized Vitamin And Carotenoid Dry Powders, Victor E. Colombo, Francoise Gerber Jan 1991

Structures And Properties Of Stabilized Vitamin And Carotenoid Dry Powders, Victor E. Colombo, Francoise Gerber

Food Structure

The development of special formulated forms of vitamin and carotenoid dry powders solved most of the technical problems encountered in handling the original pure crystalline or oily compounds. Various procedures to obtain stabilized products have been introduced on an industrial scale for feed , food and pharmaceutical purposes. Proven modes of manufacture of formulated dry powders includes the numerous spraying processes for emulsions, dispersions or solutions, and the production of adsorbates of fat-based products.

The objective of this paper is to provide an overview of stabilized vitamin and carotenoid dry powders. This contribution is intended to demonstrate the usefulness of …


Influence Of Emulsifier On The Competitive Adsorption Of Whey Proteins In Emulsions, Jean-Luc Courthaudon, Eric Dickinson, Yasuki Matsumura, Andrea Williams Jan 1991

Influence Of Emulsifier On The Competitive Adsorption Of Whey Proteins In Emulsions, Jean-Luc Courthaudon, Eric Dickinson, Yasuki Matsumura, Andrea Williams

Food Structure

The influence of Tween 20 (polyoxyethylene sorbitan monolaurate) on the composition of adsorbed protein films in hydrocarbon oil-in-water emulsions containing B-lactoglobulin and a-lactalbumin has been investigated at neutral pH. The kinetics of pol ymerization of adsorbed 13-lactoglobulin via sulphydryl-disulphide interchange is little affected by Tween 20. Add ing emulsifier after homogenization leads to slightly greater competitive d i splacement of protein from the interface for emul sions made with pure 8-lactoglobulin than for equivalent emulsions made with 0.-lactalbumin . For emulsions made with the two proteins in a 1 : 1 molar ratio, adding emulsifier after homogeniza t ion leads …
