Technological characterization of phosphocaseinate powder of buffalo milk

Globally,milk is extensively used for the production of value added dairy products owing to its rich nutritional profile. similarly,innovative dairy products can be formulated by changing the functional characteristics of milk caseins. current research was planned to assess the compositional,functional and physicochemical characteristics of phosphocaseinate powder prepared from buffalo milk. the size of casein was determined through master si zer. chemical profiling of the tested powder revealed that it contains total protein,non casein nitrogen,non protein nitrogen,moisture,ash and total solids as 87.82±0.28,0.79±0.02,0.48±0.01,4.22±0.10,8.57±0.11 and 95.76±5.10%,respectively. further more,phosphocaseinate powder contained sodium (6.79±0.39 mg/ 100g),potassium (2.98±0.75 mg/ 100g),calcium (9.68±0.08 mg/100g),magnesium (10.44±0.03 mg/100g) and phosphorus (12.25±0.05 mg/100g). different suspensions of phosphocaseinate powder i.e. 1,2,3,4 and 5% were us ed to opt imize t he funct ional propert ies . the results revealed t hat 5%suspension had the highest foaming stability (89.17±3.79%),foaming capacity (49.15±2.82%),emulsion capacity (39.57±1.97%),emulsion stability (74.49±0.98%) and protein solubility (37.09±1.48%). however,the particle size of phosphocaseinate suspensions was increased by lowering the ph. conclusively,phosphocaseinate of buffalo milk has exceptional protein features which can be exploited in numerous food products to expand their functional properties. © 2015,university of agriculture. all right reserved.
