Fat globules selected from whole milk according to their size: Different compositions and structure of the biomembrane, revealing sphingomyelin-rich domains

ChaMilk Biodiversity: Future Perspectives of Milk and Dairy Products from Autochthonous Dairy Cows Reared in Northern Italy

“…Michalsky et al in 2007 showed that cheese with small-fat globules exhibited greater stretching and elasticity and improved sensory characteristics. The content in cis-MUFA found in the present research is quite similar to data reported in recent literature (Michalsky et al, 2007;Lopez et al, 2011). Enhancement of cis-MUFA in milk is desirable for human consumption, as reported by Givens (2008): higher intakes of cis-MUFA and a reduction in short fatty acids decrease plasma insulin levels, total plasma cholesterol and LDL-cholesterol concentrations, therefore reducing risks for coronary heart diseases (CHD).…”

“…In fact, fat globules are very different in the three breeds we considered; in particular, Cabannina breed has the smallest ones. As described by Lopez et al, 2011 both size and surface area of fat globules are important parameters that can influence the mechanisms of hydrolysis of lipids by digestive enzymes. Smaller globules are better as they present a bigger surface area to enzymes, which increases digestive processes.…”

Influence of glucogenic dietary supplementation and reproductive state of dairy cows on the composition of lipids in milk

“…Accordingly, the altered composition of milk polar lipids found here was associated with a triglyceride-to-phospholipid ratio in the milk that indicated altered MFG diameter (Mesilati-Stahy and Argov-Argaman, 2014). Such structural modifications of the MFG might have nutritional implications for human health (reviewed by Michalski, 2007), as well as industrial implications due to their effect on dairy products' textural and physical properties (Michalski et al, 2003;Lopez et al, 2011). A change in MFG mean diameter is expected to alter polar lipid yield, as was found in the present study under the combined effect of treatment and progesterone concentration.…”

The Effect of Megasonic Separation on the Nutritional and Physical Properties of Food - An Overview

“…It is an alternative technique to membrane filtration [17]. Studies in the dairy science field have recently shown that milk fat globules of different sizes have different nutritional properties [18][19][20] sized fat globules [20]. Notably, smaller globules contained more medium chain length fatty acids and less stearic acid compared with larger sized globules.…”

“…Notably, smaller globules contained more medium chain length fatty acids and less stearic acid compared with larger sized globules. Furthermore, the composition of phospholipids and protein compounds located on the surface of the milk fat globule membrane [18,19] differs between small and large sized globules. Examples of nutraceutical benefits from such compounds include anti-breast cancer and anti-Alzheimer proteins.…”
