Goat milk secretion

Milk is made up of protein, fat, carbohydrate, water, minerals and vitamins. These components are packaged inside cells within the mammary gland and are released from the cells by two different pathways of secretion.1

  • Merocrine secretion
    proteins, lactose, minerals and water are released without disruption of the cell.
  • Apocrine secretion
    milk fat is enveloped by the cell membrane before being pinched off from the cell. In this process some of the cell components are also released into milk.

Milk proteins consist of whey and casein proteins. There are 4 casein proteins – αs1-, αs2-, β- and κ-casein. Low levels of αs1-casein cause the proteins, lactose, minerals and water in milk to be secreted by the apocrine pathway.2In New Zealand goat milk αs1-casein makes up only 5-10% of the total protein. Similarly, around 5% of the total protein of human is αs1-casein.3

As a result much of the proteins, lactose and water in both goat and human milk are secreted by the apocrine pathway. In cow milk, however, around 25% of the total protein is αs1-casein.4 Therefore, proteins, lactose and water in cow milk are only secreted by the merocrine pathway.

Purpose built manufacturing

The DGC plant is purpose-built solely to be a world class facility for manufacturing goat milk formula. Combined with our cooperative farm model, we are able to control the entire process from milking to distribution. So milk that comes into the plant leaves as a completed product.

The result is a safer, cleaner manufacturing process with no third parties in the production process.

Spray Drying

DGC’s spray drying plant has been designed specifically to process goat infant formula.

Spray drying is the process of removing water from the milk, producing the beginning of the fine powder that is eventually found in the finished product.

Our spray dryers are kept meticulously clean and the most recent, second spray dryer was built in 2015.

Co-operation

We are a co-operative, owned by the farmers who supply goat milk. We believe in the enduring value of the co-operative model and our objective is to grow the wealth and security of our farmer shareholders, while at the same time providing consumers with a world-leading premium quality product.

Co-operative is also a word we use to describe our business style, which is built around sustainable and long-term relationships with our partners.

We believe that goat milk is the best base from which to make infant formula. It is not the cheapest, or the most commonly available, but we do believe it is the best.

We take our responsibility seriously to deliver safe and effective nutrition to infants and young children all around the world, and to deliver brands and products that parents trust.

An infant goat milk formula made without palm oil

The fat content of formula must be modified to include several essential fatty acids. Many formulas are based on skim milk where the milk fat is replaced by vegetable oils, including palm oil.1

DGC has adopted an alternative approach, using whole goat milk to retain milk fat. Vegetable oils are still added to top up the essential unsaturated fatty acids in goat milk, but it is not necessary to use palm oil if milk fat is included in the formula.

Our research has also shown that there is also no need to use highly modified ingredients such as OPO.2
