The chemical composition of buttermilk determines the nutritional and flavour properties of the product. So, raw milk samples of buffaloes and cows were analyzed for chemical composition and pesticide residues. The Milk Composition section describes the chemical and physical properties and effects of pasteurization on the compounds in milk. chemical composition of yoghurt made from mixture of camel and sheep milk during storage through the fortification of camel milk with sheep milk. All components, except proteose-peptone nitrogen, nonprotein nitrogen, … Compositional analysis of buttermilk produced from naturally fermented milk or cream in northern Ethiopia has not been presented previously, and little or nothing is known about its nutritional and flavour attributes. The volume of milk consumed by calves during the daytime was not considered. It is the 2nd largest buffalo and goat milk producer in the world with 22.3 and 0.7 billion liters production after India and Bangladesh, respectively. In this study, the results of analysis of variance showed that there is a significant difference in total solid content among these study sites. Its opaque white color because of the fats are finely homogenized throughout the milk where as, the changes in taste are caused by the type of fodder and availability of drinking water (Yadav et al., 2015). TABLE 1. Chemical Composition of Camel Milk Camel‟s milk is generally an opaque white color and has a faint sweetish odor and sharp taste; some times it can be salty (Abbas, 2013). Some properties of caseins that are important to cheese making. Water Results showed that maximum water content was recorded in sample S 5 (84.8%) followed by sample S3 (84.6%), while minimum was recorded in sample S1 (82.8%) followed by S 2 (83.1%). thus, influences the sensory quality of milk products (Forss, 1993; Keen and Wilson, 1993). INTRODUCTION Pakistan is among top ten milk producer of the world with 35.5 billion liters annual milk production (FAOSTAT, 2010). Abstract — The chemical composition and clotting properties of milk from 45 Modicana (Mo) and Holstein (Ho) cows were assessed over the winter (December and January) and spring periods (March–April). Milk proteases come from several sources: the native milk, airborne bacterial contamination, bacteria . Introduction An increased interest in donkey milk has occurred over the last decade mainly due to its nutritional composition and functional properties. The proximate chemical compositions of milk samples such as moisture, protein, fat, solids-not-fat (SNF), lactose, total solid and ash contents also were determined. In addition, the composition of its grains and cultures and the production process The significance of seasonal and area differences in these components was measured. milk composition will be approximately the same. Chemical composition of milk and amino acid composition of protein were studied by ion exchange column chromatography. Diet modifies the chemical composition of milk and *Corresponding author. Effect of forage conservation (hay or silage) on chemical composition of milk. Annales de zootechnie, INRA/EDP Sciences, 1997, 46 (1), pp.21-26. The key constituents of milk (fat, protein, salts, lactose, enzymes, vitamins) and their composition as well as factors affecting the chemical composition of milk are described. The type and volume of milk affect its sensory, chemical and textural properties (Altay, Karbancıoglu-Güler, Daskaya-Dikmen, & Heperkan, 2013). Casein is the protein, which we utilize when making cheese. It contains protein, lipid, carbohydrate, vitamin, and mineral. Indeed, donkey milk has been reported to contain less total protein and fat and more lactose than bovine milk … The objective of the study was to determine the chemical composition and biological protein value of milk from Srednostaroplaninska sheep breed. The compositions of milk fat globule membrane are also covered. Goat milk has a similar composition with other types of milk. Buffalo's milk showed higher levels of fat, total protein (T.P), total solids (T.S) and ash than those detected in cow's milk. The levels of Na, K, Zn, Fe, Cu, Mn, niacin and vitamin C were higher and thiamin, riboflavin, folacin, vitamin Bt While the chemical composition of cow’s milk has been studied for decades, much of this information is fragmentary and very dated. 12 Cow Sheep Buffalo Goat Fat 3.9 7.2 7.4 4.0 Total protein 3.3 4.6 3.8 3.2 Casein 2.6 3.9 3.2 2.6 Whey protein 0.7 0.7 0.6 0.6 Lactose 4.6 4.8 4.8 4.3 Ash 0.7 0.9 0.8 0.8. In the three 7-day periods, the yaks were hand milked once daily at 09:00 h, and milk yield was recorded. Bovine milk is a nutritionally rich, chemically complex biofluid consisting of hundreds of different components. Milk composition affects the cheese yield and quality. Camel milk can be three times as rich in vitamin C as cow milk and represents a vital source of this vitamin for people living in arid and semi-arid areas, who often cannot obtain vitamin C from fruits and vegetables. While typical average milk compositions are readily available, information on seasonal variation in chemical composition of buffalo milk is limited -especially in the Northeastern region of the United States.
