Milk fat globule membrane isolated from buttermilk or whey cream and their lipid components inhibit infectivity of rotavirus in vitro.
Milk fat is encapsulated in a milk fat globule membrane (MFGM) that contains bioactive glycoproteins and glycolipids. The MFGM inhibits infectivity of rotavirus (RV), activity that has been attributed to its glycoprotein and carbohydrate components. However, previous studies of proteins and oligosaccharides in the MGFM have not accounted for all the bioactivity associated with the complete MFGM...
متن کاملEffect of processing on the composition and microstructure of buttermilk and its milk fat globule membranes
The effect of cream pasteurization on the composition and microstructure of buttermilk after pasteurization, evaporation and spray drying was studied. The composition of milk fat globule membrane (MFGM) isolated from buttermilk samples was also characterized. Pasteurization of cream resulted in higher lipid recovery in the buttermilk. Spray-drying of buttermilk had a significant effect on phos...
متن کاملCompositional and functional properties of buttermilk: a comparison between sweet, sour, and whey buttermilk.
Buttermilk is a dairy ingredient widely used in the food industry because of its emulsifying capacity and its positive impact on flavor. Commercial buttermilk is sweet buttermilk, a by-product from churning sweet cream into butter. However, other sources of buttermilk exist, including cultured and whey buttermilk obtained from churning of cultured cream and whey cream, respectively. The composi...
متن کاملEffect of temperature and pore size on the fractionation of fresh and reconstituted buttermilk by microfiltration.
The objective of this research was to evaluate the effect of temperature (7, 25, and 50 degrees C) and pore size (0.1, 0.8, and 1.4 micro m) on the separation of proteins and lipids (neutral lipids and phospholipids) during microfiltration (MF) of fresh or reconstituted buttermilk. Buttermilk was subjected to MF using a pilot-scale unit mounted with ceramic membranes. The MF runs were carried o...
متن کاملBovine milk fat globule membrane proteome.
Milk fat globule membranes (MFGM) were isolated from the milk of mid-lactation Holstein cows. The purified MFGM were fractionated using 1-dimensional SDS gels. Tryptic peptides from gel slices were further fractionated on a micro-capillary high performance liquid chromatograph connected to a nanospray-tandem mass spectrometer. Analysis of the data resulted in 120 proteins being identified by tw...
