[High conjugated linoleic acid (CLA) content in milk and dairy products using a dietary supplementation of sunflower seed in cows. Thrombogenic/atherogenic risk issues].

This study was undertaken to determine the effect of dietary supplementation of sunflower seed in cows on the chemical composition of milk and dairy products. Cream, butter and butter oil were prepared from milk produced by cows fed a control diet (control products) or diet supplemented with 11.2% sunflour seed (CLA-rich products).

[Review: functional foods and ingredients derived from milk].

The objective of this paper is to review the main research works related to functional foods and ingredients derived from milk. Research in functional foods has increased during last twelve years with the intention of increasing life expectancy and improving human health conditions. Probiotics, prebiotics, bioactive peptides or proteins, dietetic fibers and fatty acids, as well as the addition of fitochemical compounds in dairy products and a record of some allergic compounds are also discussed.

Purification of kappa-casien glycomacropeptide from sweet whey with undetectable level of phenylalanine.

Glycomacropeptide (GMP) found in sweet whey is a biologically active compound released from kappa-casein by the action of chymosin during cheese making. This study was undertaken to purify GMP from sweet whey as a research chemical on a laboratory scale. Glycomacropeptide was isolated from proteins and other non-GMP compounds by deproteinization with trichloroacetic acid and gel chromatography on Sephacryl S-200.

Isolation and analysis of kappa-casein glycomacropeptide from goat sweet whey.

Glycomacropeptide (GMP) was purified from goat sweet whey by anion-exchange and hydrophobic interaction chromatography. Approximately 0.06% (w/v) of sweet whey was recovered as GMP.
