What is Acid Hydrolyzed Casein?

Acid Hydrolyzed Casein is a white or light yellow powder made from premium casein, which is deeply hydrolyzed with solid acid, decolorized, desalted, concentrated, as well as spray-dried. It is very easy to absorb dampness, soluble in water, as well as also has a sauce taste. It is an acidic decay item of casein, which can be degenerated for amino acids. Acid hydrolyzed casein is an item prepared from casein and its relevant products with solid acid hydrolysis, decolorization, neutralization, desalination, drying and various other processes, the primary components of which are amino acids and also short peptides. According to item pureness (chloride content), acid hydrolyzed casein is mostly separated into 2 types: industrial quality (chloride content more than 3%) and also pharmaceutical quality (chloride content less than 3%).

Application of Acid Hydrolyzed Casein

In the pharmaceutical market, acid hydrolyzed casein is mainly used as a basic material for pharmaceutical items, such as nuclear casein dental liquid, amino acid metal chelation preparations; such as a nutritional make-up consisting of whey healthy protein and also protein source of hydrolyzed casein protein, such as formula for early infants. The proportion of whey healthy protein to hydrolyzed casein might be from concerning 90:10 to about 50:50 by weight. The degree of hydrolysis of the hydrolyzed casein can vary from about 20% to about 80%. In addition, approaches for enhancing stomach draining as well as enhancing digestibility in a target subject (eg, a premature infant) are offered. When carried out, the dietary structure can advertise digestive propulsion as well as absorbent capacity. Hence, much better growth and also advancement, especially neurodevelopment, of the target subject can be achieved.

In the food market, acid hydrolyzed casein is generally made use of as an additive for premium dietary products to supplement amino acids; as an example, to prepare a low-sensitivity newborn formula milk powder, the raw materials consist of raw milk, lactose, α-whey healthy protein, and also hydrolyzed whey protein, hydrolyzed casein, naturally active compounds, as well as also divulges an approach for preparing the milk powder, consisting of (1) mixing the raw materials with water and also entirely liquifying them to get feed liquid A, as well as the raw materials include raw milk, lactose, and α-whey protein, hydrolyzed whey protein, and also hydrolyzed casein; (2) homogenize, disinfect, focus, as well as spray-dry the product fluid An obtained symphonious (1) to get material B; (3) integrate the naturally active substances in the raw materials with the product B is blended evenly in the dry blending workshop to obtain low-sensitivity newborn formula milk powder. The invention has the advantages of thinking about hyposensitivity and enhancing immunity, addressing the trouble of infant allergic reaction by decreasing irritants and improving resistance; the preparation procedure is easy, the milk powder has excellent solubility, secure service life, as well as is difficult to oxidize.

In the daily chemical industry, acid hydrolyzed casein can be used as a raw material for amino acid skin care items and also amino acid everyday chemical items;

In the fermentation sector, acid hydrolyzed casein is mainly made use of in microbial culture media;
In the feed market, acid hydrolyzed casein can be utilized as a feed additive to strengthen the nutrition of pet feed; in the plant fertilizer sector, acid hydrolyzed casein is a vital raw material for amino acid steel chelated plant foods. It can be seen that acid hydrolyzed casein has a very vast array of uses.

Preparation of Acid Hydrolyzed Casein

A pharmaceutical grade hydrolyzed casein and its preparation method:

(1) Mix casein and concentrated hydrochloric acid in an autoclave at a mass/volume ratio (g/mL) of 1:0.6~1:1;

(2) Adjust the pressure of the kettle to 200-300kPa, the temperature to 100-120°C, heat and hydrolyze for 2-6 hours, and steam condenses and refluxes during the hydrolysis process;

(3) Release the pressure after hydrolysis, change the reflux device to a distillation device, raise the temperature to 180~220°C, and heat

(4) After cooling the reactor, open it, add activated carbon at a ratio of 1-2:1 mass ratio of activated carbon to casein, add water at a ratio of 8-16:1 mass ratio of water to casein, and adjust the kettle pressure to 150~250kPa, temperature 100~120℃, heat decolorization for 2~4h, steam condenses and refluxes during the decolorization process;

(5) After cooling down to room temperature after depressurization, perform suction filtration operation on the mixture in the kettle, and collect the filtrate;

(6) Weigh the anion exchange resin according to the mass ratio of casein to resin in the ratio of 1:10 to 1:20, fill it in the ion exchange column, wash with distilled water to remove impurities; add 0.5mol/ Soak in LHCl solution for 2 hours, wash with distilled water until neutral; then add 0.5mol/L NaOH solution 4 times the mass of the resin to soak for 2 hours, wash with distilled water until neutral, and set aside;

(7) Use a peristaltic pump to transport the filtrate to the upper end of the ion exchange column at a flow rate of 2.0-6.0 mL/min, and collect the effluent at the lower end of the column;

(8) Place the effluent in a steel tray for freeze-drying at a temperature of -50°C, a pressure of 500-600Pa, and a time of 24 hours. The obtained powdery product is pharmaceutical grade hydrolyzed casein.

Study on Biological Activity of Acid Hydrolyzed Casein

Bai Guijie et al. explored the effects of different acid-hydrolyzed casein on the capsular polysaccharide production of W135 and Y Neisseria meningitidis (meningococcus). Methods The acid hydrolyzed casein with NaCl mass fraction of 37% and 14% was used as organic nitrogen source to prepare improved semi-comprehensive high-salt medium and low-salt medium. Group Y and group Y meningococci, and compared the growth time of these two strains in the two media, the bacterial density of the harvest liquid (A600 nm value), and the capsules in the supernatant of the harvest liquid after removal of bacterial cells and after removal of complex polysaccharides Polysaccharide content, and refined sugar yield after purification; compare the effects of cetyltrimethylammonium bromide (CTAB) solutions with different final contents in the high-salt medium harvest solution and its 2-fold dilution on the precipitation effect of polysaccharides influences.

Results There was no significant difference in the culture time of W135 group and Y group meningococcus in the two media (P>0.05), but the bacterial density of the harvest liquid of the high-salt medium and the supernatant of the harvest liquid after removing bacteria The content of polysaccharides in the harvest liquid of high-salt medium was higher than that of low-salt medium, and the difference was statistically significant (P<0.05). <0.05).

After 2-fold dilution of the high-salt culture solution, when the final volume fraction of CTAB was 0.04%, the polysaccharides of group W135 and group Y meningococcus were all precipitated, while the undiluted high-salt culture solution even if the final volume fraction of CTAB was increased to 0.14%, still remained unchanged. The W135 and Y meningococcal polysaccharides could not be completely precipitated. Conclusion Different acid-hydrolyzed casein can affect the growth density and capsular polysaccharide production of W135 and Y meningococci, and it is necessary to control the salt content of the harvest liquid when using CTAB solution to precipitate capsular polysaccharide.
