Milk lipid globules: control of their size distribution.

Milk lipid globules: control of their size distribution.

Micro lipid droplets fuse with each other in vivo to form larger precursors of milk lipid globules. The extent of fusion dictates the size range of lipid globules in milk. A cell-free system in which micro lipid droplet fusion can be induced has been developed. Fusion was promoted by calcium and a protein complex from cytosol. Exogenously supplied gangliosides were potent fusion-promoting agent...

Size-dependent lipid content in human milk fat globules.

Human milk fat globules (HMFGs) are considered to constitute a triglyceride-rich source of fat and energy. However, milk contains lipid particles at different sizes ranging from tens of micrometers to less than 1 microm. In particular, the physical, chemical, and biological properties of submicron sized particles are poorly described. Individual HMFGs were analyzed using laser trapping confocal...

The Creaming Properties and Size Distribution of Fat Globules in Camel Milk

The natural creaming of raw and heated camel milk was studied. Compared with cow (Bos taurus) milk, camel (Camelus dromedarius) milk showed very slow creaming rate in both raw and heated milk at refrigerator and room temperatures. Fat globule size distribution was similar in cow and camel milks. The creaming ability was also studied in various combinations of skim milks and creams of raw camel ...

Reducing Fat Globules Particle-Size in Goat Milk: Ultrasound and High Hydrostatic Pressures Approach

In milk processing, special emphasis is directed to fostering the taste and healthy values of goat milk. Therapeutic properties of goat milk are very well known. Comparison of cow and goat milk at the level of chemical composition suggests significant differences in their physical and chemical characteristics. Smaller diameter of fat globules (natural homogeneity), high portion of essential ami...
