Milk protein concentrate, known as MPC, is an ingredient derived from milk, containing a combination of casein and whey proteins. It is widely used in cosmetic and personal care products, as well as in the food industry, for its moisturizing, nourishing, and regenerative properties. Due to its rich composition of essential amino acids, milk protein concentrate helps improve the health of skin and hair by providing nourishment and promoting repair.

Chemical Composition and Structure

Milk protein concentrate is primarily composed of casein and whey proteins, with varying proportions of lactose and fat, depending on the extraction process. These proteins are rich in essential amino acids, which play a crucial role in cell regeneration and maintaining the skin's protective barrier. Milk proteins also contain vitamins and minerals, such as calcium, which contribute to the health of skin and hair.

Physical Properties

Milk protein concentrate typically appears as a white or creamy powder that is water-soluble. It can easily be incorporated into cosmetic formulations such as creams, lotions, shampoos, and conditioners due to its versatility and ability to bind water, improving hydration and the texture of products.

Production Process

It is produced through the filtration of milk, separating and concentrating the proteins. Ultrafiltration or microfiltration processes remove some lactose and fat, resulting in a high-protein concentration. The final product is dried to obtain a powder that can be used in cosmetic and food formulations.

Description of raw materials used in production.

• The primary raw material for the production of MPC is skimmed milk.

Step-by-step summary of the industrial production process.

• Skimmed milk is subjected to an ultrafiltration process, which uses membranes to concentrate the proteins and remove water and other soluble components.
• During ultrafiltration, the milk proteins are concentrated while lactose, minerals, and water are partially removed.
• The resulting concentrate can then be spray-dried or freeze-dried to achieve a dry powder.
• The MPC powder is then packaged for sale and use.

Milk protein concentrate typically appears as a white or cream-colored powder.

Commercial applications:

Enriched Dairy Products. MPC is used to boost the protein content in various dairy products such as yogurts, ice creams, and cheeses.

Dietary Supplements. Due to its high protein content, MPC is often used in protein powder supplements and protein bars.

Functional Foods. MPC can be used to enhance texture and structure in products such as bread, cookies, and snacks.

Nutritional Drinks. MPC-based drinks are often targeted at specific populations, such as the elderly or athletes, to provide a concentrated protein intake.

Infant Food. It's used in infant formulas and complementary foods to provide a balanced protein source.

Milk Replacers. MPC can be used in blends for making dairy products like cream, butter, and cheese to improve yield and product characteristics.

Cosmetic

• Skin Care: Milk protein concentrate is used in creams, lotions, and facial masks for its moisturizing and regenerative properties. It helps keep the skin soft and smooth, promoting cell renewal and improving skin elasticity.

• Hair Care: In shampoos, conditioners, and hair masks, milk protein concentrate strengthens and nourishes the hair, enhancing shine and preventing damage caused by dryness and chemical treatments.

• Anti-Aging Products: Due to its high protein and amino acid content, milk protein concentrate is often used in anti-aging products to promote skin regeneration and reduce the signs of aging.

Health and Safety Considerations

Safety in Use
Milk protein concentrate is generally considered safe for use in both cosmetic and food products. It is well tolerated by the skin and is not known to cause irritation or sensitization, making it suitable for sensitive skin.

Allergic Reactions
People with allergies to milk proteins should avoid products containing milk protein concentrate, as it may trigger allergic reactions. Always check product labels carefully.

Toxicity and Carcinogenicity
There is no evidence that milk protein concentrate is toxic or carcinogenic. It is a natural, safe ingredient approved for use in cosmetic and food products at recommended concentrations.

Environmental and Safety Considerations
Milk protein concentrate is a byproduct of milk processing, and when produced sustainably, it has a relatively low environmental impact. However, the sustainability of the production process depends on responsible animal resource management and production efficiency.

Regulatory Status
Milk protein concentrate is approved for use in cosmetics and food products in many regions, including the European Union and the United States. It is considered a safe ingredient and is widely used across multiple industries.

Safety

It contains lactose so it cannot be taken by people with lactose intolerance.
