Typical gross composition (kg/100 kg) of milk of cow, sheep, buffalo and goat milk). Cow milk composition 3. The compositions of milk fat globule membrane are also covered. Introduction An increased interest in donkey milk has occurred over the last decade mainly due to its nutritional composition and functional properties. thus, influences the sensory quality of milk products (Forss, 1993; Keen and Wilson, 1993). Data collected in this study can be useful for the manufacture of a wide variety of specialty dairy products such as symbiotic buffalo milk yogurt. Physio-chemical properties of the four treatments of milk for production Halloumi cheese Physicochemical Treatment* T1 *100Goat milk T2 50Cow milk T3 75Cow milk T4 100Cow milk Total solids (%) 12.2±0.05a 11.9±0.07b 11.7±0.02c 11.5±0.07d chemical composition 1. In this study, the results of analysis of variance showed that there is a significant difference in total solid content among these study sites. Goat milk has a similar composition with other types of milk. TABLE 1. Milk having high total solids has high fat, protein and casein content. It s major products formed during fermentation are lactii c components (Halléet al., 1994). The complex sugars by a matrix of polysaccharides. Effect of forage conservation (hay or silage) on chemical composition of milk. 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). clumped together with casein (milk proteins) and chemical composition of kefir is shown in Table 1. Paneeris non-fermentative, non-rennet, non-melting and unripened type of cheese similar to the white cheese (Chandan, 2007). The cows came from 4 farms of the Ragusa region (Italy). Most of the whey proteins will be lost with the whey during cheese making. Constantin, A.M., et al. In the three 7-day periods, the yaks were hand milked once daily at 09:00 h, and milk yield was recorded. Milk Chemical Deterioration Proteins can be degraded by enzyme action or by exposure to light. 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. Microbial quality and chemical composition of raw milk in the Mid-Rift Valley of Ethiopia Camel milk is also rich in unsaturated fatty acids and B vitamins.
