Plastic cream is a highly viscous, paste-like cream with a fat content of 60-85%. It is a key ingredient in the production of butter oil, also known as anhydrous milk fat (AMF). The high fat content of plastic cream makes it ideal for this purpose. It is used to adjust the fat content of milk to create standardized milk products. By blending plastic cream with lower-fat milk, dairy producers can achieve the desired fat content for various milk products. It is produced by re-separating normal cream containing 30-40% fat or by using a specially designed plastic cream separator to yield high-fat cream.

Plastic cream is a highly viscous, paste-like cream with a fat content of 60-85%
The high fat content of plastic cream, ranging from 60-85%, gives it its characteristic viscosity and texture. This high-fat content also makes it ideal for use in butter oil production. Butter oil, or anhydrous milk fat (AMF), is a highly concentrated form of milk fat with a fat content of at least 99.8%. It is used in a wide range of food products, including baked goods, confectionery, and dairy-based sauces. The process of making butter oil from plastic cream involves removing the water and non-fat solids to produce a pure fat product.
Plastic cream is also used in the preparation of standardised milk. By blending plastic cream with skim milk or low-fat milk, dairy producers can increase the fat content to create standardised milk products. This process of blending plastic cream with lower-fat milk is known as recombination and allows for the creation of products such as whole milk, reduced-fat milk, and low-fat milk.
Plastic cream can be made by re-separating normal cream containing 30-40% fat or by using a specially designed plastic cream separator to yield high-fat cream. The initial product, whether cream or milk, must be pasteurised before separation. Pasteurisation involves heating the cream or milk to about 74°C for 30 minutes, followed by cooling to 60-66°C before re-separation. The resulting products of this separation will be plastic cream and skim milk.

It is used in butter oil production and the preparation of standardised milk
Plastic cream is a unique dairy product with a high fat content and a thick, paste-like consistency. It is a key ingredient in the production of butter oil, also known as anhydrous milk fat (AMF), due to its high fat content. The process of making butter oil from plastic cream involves removing water and non-fat solids from the plastic cream to produce a pure fat product with a fat content of at least 99.8%. This pure fat product is then used in a wide range of food products, including baked goods, confectionery, and dairy-based sauces.
Plastic cream is also used in the preparation of standardised milk. Standardised milk is milk that has been adjusted to a specific fat content to meet regulatory standards or consumer preferences. By blending plastic cream with skim milk or low-fat milk, dairy producers can achieve the desired fat content for various milk products, such as whole milk, reduced-fat milk, and low-fat milk. This process of blending plastic cream with lower-fat milk allows for the creation of standardised milk products with consistent fat content.
The production of plastic cream involves two primary methods. One method is the re-separation of normal cream, which typically contains 30-40% fat, to increase its fat content. This process utilises a cream separator to further concentrate the fat in the cream. The other method involves using a specially designed plastic cream separator, which can produce high-fat cream directly from milk in a single step, making it more efficient and requiring minimal processing.
The quality of plastic cream is crucial for its various applications, and several factors must be monitored and controlled during production, including fat content and temperature. Maintaining the consistency and stability of plastic cream can be challenging due to its high fat content, and temperature fluctuations and improper handling can cause the fat to separate, resulting in an inconsistent product. Therefore, strict temperature control and proper handling procedures are essential to ensure the stability and quality of plastic cream.
Plastic cream plays a vital role in the dairy industry, not only in butter oil production and standardised milk preparation but also in the development of other dairy products. Its high fat content and unique properties make it a versatile and valuable ingredient. With advancements in dairy technology, plastic cream is expected to remain a key player in dairy production.

It is made by re-separating normal cream containing 30-40% fat or using a plastic cream separator
Plastic cream is a high-fat dairy product with a fat content ranging from 60% to 85%. It is distinct from butter, which is a water-in-fat emulsion, whereas plastic cream is a fat-in-water dispersion. This high fat content gives plastic cream its characteristic viscosity and texture.
There are two primary methods for producing plastic cream. One method involves re-separating normal cream, which typically contains 30-40% fat, to increase its fat content. This process involves separating the cream from milk, which can be done by skimming the higher-fat layer from the top of unhomogenized milk, as the fat is less dense and rises to the top. This process can be accelerated by using a centrifuge, or "separator". The cream is then further concentrated to increase its fat content.
Another method for producing plastic cream involves using a specially designed plastic cream separator. These machines are specifically engineered to produce high-fat cream directly from milk, achieving a higher fat concentration in a single step. This method is more efficient and can produce plastic cream with minimal processing.
The production of plastic cream requires careful monitoring and control of various factors, including fat content, temperature, and hygiene. Temperature control is essential to maintain the stability of the emulsion and prevent the fat from separating out. Plastic cream must be kept at the appropriate temperature during separation and storage, and strict hygiene standards must be maintained to prevent contamination.
Plastic cream serves several important functions in the dairy industry. It is a key ingredient in butter oil production and is used to adjust the fat content of milk to create standardized milk products. The high fat content of plastic cream makes it ideal for these purposes.

Plastic cream can be stored for several years without spoilage
Plastic cream is a highly viscous, paste-like cream with a fat content of 60-85%. It is a unique dairy product with a thick, paste-like consistency, distinct from the smooth, pourable consistency of regular cream. This high fat content sets it apart from other creams and makes it ideal for butter oil production.
The process of making plastic cream involves removing the water and non-fat solids to produce a pure fat product. It is made by re-separating normal cream containing 30-40% fat or by using a specially designed plastic cream separator to yield high-fat cream. This involves pasteurizing the initial product, i.e., heating the cream to about 74°C for 30 minutes, followed by cooling to 60-66°C before re-separation. The resulting products are plastic cream and skim milk, which is then packaged and stored for further use.
Plastic cream is essential in the dairy industry for butter oil production and the preparation of standardized milk. It is used to adjust the fat content of milk to create standardized milk products. By blending plastic cream with skim milk or low-fat milk, manufacturers can achieve the desired fat content for products such as whole milk, reduced-fat milk, and low-fat milk. This process of concentrating cream causes the rupturing of the fat globule membrane, facilitating easier access to the fat nucleus.
Due to its high fat content, plastic cream has a very high keeping quality and can be stored for several years without spoilage. This is especially true when it is frozen, as the freezing temperatures further inhibit the growth of spoilage microorganisms.
In summary, plastic cream is a highly viscous cream with a fat content ranging from 60-85%. It is primarily used in the dairy industry for butter oil production and the preparation of standardized milk products. The process of making plastic cream involves pasteurization and separation techniques to achieve its high fat content. This high fat content not only makes it ideal for various dairy applications but also gives it a long shelf life, allowing it to be stored for several years without spoilage.
