Who invented casein

We have an activity here that allows you to make your own plastic. This is a wonderful exhibit area that changes every day and has lots more activities. We also, for your reading pleasure, have gone on to extend the activity to discuss how plastic gets made and add a little more science behind, Plastic Milk.

Heat, stirring frequently until the milk boils. The milk will form tiny lumps curds in a clear liquid whey. The yellowish glob is made of fat, minerals and the protein casein. The combination of heat and vinegar acetic acid helps to pull out or precipitate the protein casein from the milk.

Plastic is now synthesized from petroleum products but before this way of making plastic, it was common to make natural plastics from plants and animal fat. In fact, this plastic is environmentally friendly because it will eventually decompose, unlike plastics made from petroleum products.

Stop snickering! You might be thinking to yourself right now… there is fat and protein in my milk? What is in my milk? Milk is made up of fat, protein, minerals, water and carbohydrates. The exact composition of milk according to Cornell University is Visit the site and learn all about the different components of milk. The important components of milk for making plastic are the fats, minerals and protein.

There are two main proteins found in milk, casein and whey. The casein protein contains phosphorus and coagulates because the acetic acid vinegar causes the pH of the milk to drop below 4. In Britain, a wet process starting with milk curds was patented in by a Russian student, Victor Schutze, from Riga. This material was called Syrolit and a factory of the same name was set up in a disused cloth mill at Stroud in Gloucestershire. However, it was not successful and by the company was bankrupt.

A new company, was established at the same premises to manufacture casein using the dry process. The new product was called Erinoid and this was also adopted as the name of the company.

Production commenced in and as supplies of Galalith were cut off at the commencement of World War I, the material found a ready market and button manufacturers from Birmingham were waiting on the doorstep for the first consignments. Young and Wolf pioneered the slicing of casein button blanks from rod in the UK.

Charles Horner Ltd. Their brand name was Dorcasine. At the commencement of World War II supplies of raw casein granules were no longer obtainable from Europe, the traditional source, and the CPA were encouraged by the British Government to seek alternative supplies in order to make buttons for military use.

Argentina provided this need. Perhaps the greatest contribution of the CPA was in the s to improve the process for manufacturing casein granules. With the co-operation of the New Zealand and Norwegian dairies, this resulted in a casein of improved quality with a better base colour thus increasing the colour range, especially of very pale colours. Erinoid remained the major producer of casein plastics in the UK until they stopped manufacture in about
