Uses
Different sources of media describe the Uses of 9000-71-9 differently. You can refer to the following data:
1. α-Casein from bovine milk is an Immunoglobulin E (IgE)-binding epitope belonging to the Casein phosphoprotein family. It has been used in studies of children with insulin-dependent diabetes mellitus (IDDM), due to the strong cross-reactivity of α-casein antibodies with insulin. Studies of children displaying (IDDM) show higher levels of α-casein antibodies than control siblings, which may serve as a risk marker for IDDM.
2. β-Casein from bovine milk is an Immunoglobulin E (IgE)-binding epitope belonging to the Casein phosphoprotein family. It has been studied as a generator of peptides responsible for biological activities such as opiate, immunostimulating, antibacterial, and peptidase inhibitors.
3. Casein is the principal milk protein which is prepared commercially
from skim milk by the precipitation with lactic, hydrochloric, or
sulfuric acid. it can also be produced by the use of lactic acid-pro-
ducing bacteria. caseins are usually identified according to the acid
used, such as lactic acid casein, hydrochloric acid casein, and sulfuric
acid casein. the principal form in which casein is used is casein
salts, of which sodium and calcium caseinate are the most common.
rennet casein is obtained from skim milk by the precipitation with
a rennet-type enzyme. casein is used in the protein fortification of
cereals and bread, and in fabricated cheeses.
Definition
Different sources of media describe the Definition of 9000-71-9 differently. You can refer to the following data:
1. A phosphoruscontaining
protein that occurs in milk and
cheese. It is easily digested by young mammals
and is their major source of protein
and phosphorus. It has been used in the
manufacture of paper and buttons.
2. casein: One of a group of phosphate-containing proteins (phosphoproteins)found in milk. Caseins areeasily digested by the enzymes ofyoung mammals and represent amajor source of phosphorus.
Production Methods
casein is a form of concentrated casein protein (one of the two major proteins found in milk) and is derived from skim milk. Depending on the method of manufacture. casein is classified as rennet casein or acid casein. In the production of rennet casein. skim milk is treated with an enzyme that causes the casein to coagulate and separate from other milk components. Acid casein is produced when skim milk is exposed to an acid treatment which causes the protein to precipitate out from other milk components. Both rennet and acid casein are high- protein products with protein concentrations from 85 to 90 percent. Both rennet and acid casein also contain very little whey protein and therefore cannot be classified as MPC.
All forms of casein arc classified tinder HTS subheading 3501.10.50. Imports of casein enter the United States free of duty. The US. market for casein is served almost exclusively by imports. casein production recently began in the United States. although is not yet commercially significant. Unlike imported casein. which is produced from fresh. liquid skim milk, U.S. production of casein uses reconstituted SMP as the starting ingredient.
General Description
Casein from bovine milk is a phosphoprotein and forms three-dimensional colloidal supramolecular micelles. There are four main types of casein which make up approximately 80% of the total protein in bovine milk: α-s1 casein, α-s2 casein, β-casein, and κ-casein. Casein is proposed to be the main protective constituent in milk. Casein is an amphiphilic protein.
Biochem/physiol Actions
Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.
Check Digit Verification of cas no
The CAS Registry Mumber 9000-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9000-71:
(6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*1)=69
69 % 10 = 9
So 9000-71-9 is a valid CAS Registry Number.

Microencapsulated pendimethalin and method of making and using same
-
, (2008/06/13)
Pendimethalin microencapsulated in a microcapsule comprised of a water-soluble film forming polymer. The present invention also includes a method of microencapsulating low-melting agriculturally active materials, such as pendimethalin. The microencapsulation process comprises the steps of heating pendimethalin to a molten state. The molten pendimethalin is then combined with an aqueous solution of a water-soluble, film-forming polymer at a temperature sufficient to maintain the pendimethalin in its molten state. The pendimethalin is then emulsified in the aqueous solution so that the pendimethalin has a primary particle size of between approximately 0.1 and 10 microns. The resulting dispersion or emulsion is then spray dried at a temperature between approximately 50° C. and 220° C. so as to microencapsulate the pendimethalin in the polymer. Compounds for promoting the rapid solidification of the pendimethalin am also disclosed.
