CFUs/mL; Organoleptic Properties; and the effects of temperature, acid and enzymes on proteins in Selected Milks

CFUs/mL; Organoleptic Properties; and the effects of temperature, deadly and enzymes on proteins in Selected Milks consider:         This investigate examined the organoleptic properties, clotting of proteins and microbial contamination of cows take out. sundry(a) samples of draw were orientationd for their sweetness, mouth-feel, cooked taste and creaminess, colour was also noted. Low gilded milks were less creamy and less viscous than those with just milk naughty. The colour of panoptic cream milk was whiter than low fat milk.         Results for method A were unreliable due to contamination of samples; only there is rough evidence that pasteurised milk contained thermophilic microorganisms.          rule B employ rennet and pungent to precipitate casein from whey. whey proteins, -Lactalbumin and -lactoglobulin, were precipitated using temperatures up to 100 oC. This precipitate was brown in colour and resembled skin. seg ment B of method B compared the affects of temperature and acid on coagulation of milk proteins. Whey proteins coagulated at 60 oC in both acidified and non-acidified milk. Curds formed in non-acidified milk at 60 oC and at 60 oC and 41 oC in acidified milk. Precipitates formed were lumpy. Rennet did not cause milk to coagulate in the absence of acid.                            Introduction:         This audition was divided into three components.

The showtime method examined the bacterial counts in raw, pasteurised and sterile (UHT) milk. In the second metho d we precipitated proteins in milk using enz! ymes, acid and heat. The third part of this experimentation compared the organoleptic properties of selected milks. These three methods are tagged part A, B and C respectively. The milk discussed throughout this explanation is cows milk. Milk contains lactose (a milk sugar), milk fat, protein and minerals, like atomic number 20 (Paulus, 2002). Milk comprises of 88% water, 5% carbohydrate, 3.5% protein and 3.3% fat and has a pH of 6.6... If you want to get a full essay, order it on our website: OrderCustomPaper.com
