Abstract : Lactate is the product of fermentation of lactose in the digestive tract of milk consumers. The lactate has benef icial effect on health for the regulation of the milk protein digestion and calcium absorption. However, lactate has two stereoisomere named D and L form (for Dextrogyre and Levogyre). In dietetic, D form is not recommended because it could have negative effect on health, especially on young baby. The present study gives some preliminary results regarding the content of the D- and L-lactate in cow and camel milk. Twenty dromedary camel milk samples and 3 cow milk samples from Kazakhstan were analyzed to determine main composition, especially the lactates forms in order to compare these two species. The content of total lactate in camel milk was comparable to cow milk (1.82 – 2.49 g/l), but the quantity of L-Lactate was 100 times more in camel milk compared to cow milk - 2.21% of the total lactate vs 0.02% in camel and cow milk respectively. Further analyses are necessary to understand the role of the microflora present in each specific milk. (Résumé d'auteur)
