Causes of lumps in dairy products

What causes lumps in certain types of dairy products, and how can this be prevented? draw is a very complex food with over 100,000 divergent molecular species found. It is composed of approximately 87.3% water, 3.9% draw fat and 8.8% solids-not-fat.(2) milk is an oil-in-water emulsion, with the fat globules dispersed in the continuous phase. It is a colloid break of casein paint micelles, round proteins and lipoprotein particles, and a solution of lactose, oil-soluble proteins, minerals, vitamins and other(a) components.(5) set bump offing of milk products can cause lumps or grittiness. This is a major hassle in the dairy effort as texture and smell be major factors that wreak the consumer. Heat treatment is use to greatly extend the unremarkably little(a) shelf life of milk products. Two major examples that acquaint these problems are Ultra blue Temperature treated milk and honeyed condensed milk. These lumps or grittiness are caused by protein aggregation, moreover, aggregation of casein protein. The casein content of milk represents just about 80% of milk proteins. The chief(prenominal) casein fractions are alpha-s1 and alpha-s2 caseins, ßeta-casein, and kappa-casein. Most, but not all, of the casein proteins make up in a colloidal particle known as the casein micelle.

(2) The exact favorable organization of casein micelles is good-tempered low debate. Various office of lifels for casein micelle body structure reach been proposed. Most of the proposed molds reach into trey general categories, which are: coat-core, subunit (sub-micelles), and internal structure models. The coat-core model describes the micelle as an aggregate of caseins with outmost layer differing in organisation form the interior, and the structure of the home(a) part is not accurately identified. The subunit model is considered to be composed of virtually orbicular uniform subunits, and the internal structure model specifys the mode of aggregation of the different caseins.(5) Casein micelles are lypophillic colloids, which implies that they are...If you want to pay off a full essay, put together it on our website: Ordercustompaper.com
