Analysis of Caseinate emulsion by Diffusing wave spectroscopy (DWS) (CAT#: STEM-MB-0848-WXH)

Introduction

Casein is the main protein in cow's milk. It forms the basic ingredient of cheese and is used in the form of caseinate in the food industry. Casein is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and Cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.

Principle

Diffusing-wave spectroscopy (DWS) is an optical technique derived from dynamic light scattering (DLS) that studies the dynamics of scattered light in the limit of strong multiple scattering. DWS is able to give information about the local dynamics of particle dispersion in a highly turbid medium. It has been widely used in the past to study colloidal suspensions, emulsions, foams, gels, biological media, and other forms of soft matter. If carefully calibrated, DWS allows the quantitative measurement of microscopic motion in a soft material, from which the rheological properties of the complex medium can be extracted via the microrheology approach.
The technique of DWS depends on the scattering of light from highly turbid suspensions. A sample of the suspension is illuminated by light from a laser and the incoming photons are multiply scattered. This scattered light is detected and subjected to autocorrelation analysis.

Applications

• Diffusing Wave Spectroscopy (DWS) is an advanced light scattering technique, which is primarily applied for microrheology and particle sizing.
• DWS has been applied in biomedical and clinical areas, especially in monitoring cerebral blood flow (CBF).
