Demineralized Whey Powder (เวย์โปรตีนผง)

Definition and Description

Demineralized Whey Powder (DWP) is a dairy-based ingredient derived from liquid whey, which is a byproduct of cheese production. As the name suggests, DWP undergoes a demineralization process to reduce its mineral content, usually by 40%, 70%, or 90%, depending on the intended use. It is a white to light cream-colored, free-flowing powder with a mildly sweet dairy taste.

Symbol: DWP
E Number: E888

Sources and Processing

The source of Demineralized Whey Powder is liquid whey, which comes from cow’s milk during cheese-making. The whey undergoes several processes:

1. Clarification and pasteurization to remove fat and pathogens.
2. Demineralization using ion-exchange or nanofiltration techniques to reduce minerals such as calcium, sodium, potassium, and magnesium.
3. Concentration and spray-drying to turn it into a fine powder.

Uses in Food Products

Demineralized Whey Powder is primarily used in food products requiring low mineral content and a sweet, clean dairy flavor. It is highly digestible and blends well in formulations.

Common Food Applications:

1. Infant formula and baby food
2. Confectionery (e.g., chocolates, toffees)
3. Bakery products (e.g., cakes, cookies)
4. Ice cream and dairy desserts
