Fat Separation in Evaporated Milk. III. Gravity Separation and Heat Stability

Fat Separation in Evaporated Milk II. Age-Thinning Of Concentrated, Sterilized Milk

Phase stability of concentrated dairy products.

The interactions between the two most important colloids in milk, fat globules and casein micelles, were investigated. Mixtures of oil droplets (as a model for fat globules) and casein micelles were prepared, and their phase behavior was studied. It was found that the oil droplets and the casein micelles phase separate as a result of depletion interaction. The experimentally determined phase bo...

Fat-Feeding Practices for Lactating Dairy Cows

Supplementing cows with fat can have several beneficial effects. It usually increases the energy density of the diet as starch or fiber is replaced with fatty acids. If milk production is increased, then feed efficiency may be improved. Less heat may be produced in the rumen during digestion of fat-supplemented diets as fatty acids are not digested in the rumen. Less heat produced during digest...

Milk Fat Depression in Dairy Cows – Influence of Supplemental Fats

Supplementing cows with fat can have several beneficial effects. It usually increases the energy density of the diet when starch or fiber is replaced with fatty acids. If milk production is increased, then feed efficiency may be improved which usually translates into more profit. Less heat may be produced in the rumen during digestion of fat-supplemented diets as fatty acids are not digested in...

Implementation of flotation and gravity separation, to process Changarzeh sulfide-oxide lead ore

This study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% Pb, 1.91% Zn taken from Changarzeh mine, South Natanz, Iran. The effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, pH and solid content were investigated in relation t...
