Amino Acid Composition, Antioxidant and Antihypertensive Activity in Extracts from Mexican Añejo Cheese.

Research Background: Authentic Mexican cheeses have potential health benefits, although there are few studies on their bioactive components. In this study, we analysed soluble extracts from añejo cheese from Zacazonapan (Mexico), obtained from two dairies (A and B) that used milk from cows of different breeds and differed in processing.

Experimental Approach: The soluble extracts of Zacazonapan añejo cheese during ripening (0, 30, 95 and 180 days) were used to determine proximate composition, amino acid composition, peptide profile, molecular mass profile, antioxidant and antihypertensive activities.

Mechanisms for the interaction of the milk fat globule membrane with the plasma membrane of gut epithelial cells.

The milk fat globule membrane (MFGM) provides infants and adults with several health benefits. These are not derived solely from its unique composition, but also from arrangement of lipids in the MFGM that, in the case of newborns, could reach the intestine partially intact. Fluorochromes associated with lipid derivatives were used to prove a fusion process between the MFGM and the cellular membrane of differentiated Caco-2 cells.

Purification, Characterization, and Antiproliferative Activity of a Single-Chain Lectin from Vicia palaestina (Fabaceae) Seeds.

Vicia palaestina Boiss. is an annual herb that grows in dry areas of eastern Mediterranean countries. It belongs to section Cracca subgenus Vicilla, which is characterized by having a high content in the non-protein amino acid canavanine.

Physicochemical characteristics and antiproliferative and antioxidant activities of Moroccan Zantaz honey rich in methyl syringate.

Zantaz honey is a monofloral variety produced from the melliferous plant Bupleurum spinosum (Apiaceae), a shrub that grows mainly in the Atlas Moroccan Mountains. Determination of the polyphenol composition revealed that methyl syringate accounts for more than 50% of total polyphenols, which represents a very useful parameter for the characterization of this monofloral honey. Epicatechin, syringic acid and catechin are also abundant.

Characterization of Vicia ervilia (bitter vetch) seed proteins, free amino acids, and polyphenols.

Vicia ervilia is an ancient crop from the Mediterranean Region. It may represent a useful source of proteins for food and animal feed, as well as bioactive components. Seed samples from 39 populations of V.
