Basic Info of Casein protein
What is Bretazenil?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Casein protein which has developed particularly rapidly in recent years. Do you know about Casein protein?
The official answer: Casein is the main protein found in the milk of mammals including ewes, sheep, and humans. Casein is the predominant protein in cow’s milk and albumin is the predominant protein in human milk. Casein is a large, hard, dense curd that is extremely difficult to digest and break down. Casein is the most abundant protein in milk and is mainly used as a food ingredient or microbial medium. Casein phosphopeptide, which is made by protein enzymatic hydrolysis, has the function of preventing mineral loss, especially its function of promoting the efficient absorption of macronutrients (Ca, Mg) and trace elements (Fe, Zn, Cu, Cr, Ni, Co, Mn, Se), making it a “mineral carrier”. “It can combine with metal ions, especially calcium ions, to form soluble complexes.
What’s the application of Casein protein?
Acid casein is mainly used as a base material for paints, a binder for wood, paper, and cloth, an additive for food, etc. As a base material for paints, it accounts for about half of the total consumption, has excellent water resistance, disperses well in pigments, and improves the uniformity of paints. In addition, crude rennet protein is mainly used in the manufacture of plastic buttons because of its good fluidity and ease of coating construction. Compared with other resin buttons, casein buttons have good dyeability, processability, and brightness of color, and the quality is in the middle and upper level in buttons. Casein is evenly mixed with slaked lime, sodium fluoride, copper sulfate, and then with kerosene to get casein glue, which is a glue used in the aviation industry and wood processing sector. Casein is also used in medicine and biochemical reagents. Casein is the main protein in the milk of mammals including ewes, sheep, and humans.
(1) Fresh milk is skimmed and acid (lactic acid, acetic acid, hydrochloric acid, or sulfuric acid) is added to adjust the pH to 4.6 so that the microgel of casein loses its charge and coagulates and precipitates. The casein obtained by this method is called acid casein, but the acid casein obtained by adding different types of acid is almost indistinguishable. Casein is a white to yellowish powder or granule with a slightly milky and sour odor. It only swells in water but can be dispersed and dissolved in water if ammonia, alkali, and salt are added. It is soluble in strong acid, diethanolamine, morpholine, urea, formamide, hot phenol, and Turkish red oil.
(2) Milk and crude rennet act to form a coagulated precipitate called crude rennet casein, which is white in granular form, almost tasteless and odorless, and produces a characteristic odor when heated and burned. The rennet casein has a higher ash content than acid casein.
