Cocoa Powder

Alkalized Cocoa Powder is nutritious, contains high-calorie fat and rich protein and carbohydrates. Cocoa powder also contains a certain amount of alkaloids, theobromine and caffeine, which have the function of expanding blood vessels and promoting blood circulation in the human body. The consumption of cocoa products is very beneficial to human health.

Cocoa powder uses natural cocoa beans as raw materials. Alkalized Cocoa Powder is a brownish-red powdery solid made by screening, roasting, refining, alkalization, sterilization, squeezing, powdering and other processes using an imported hydraulic press production line. Alkalized Cocoa Powder has a natural cocoa fragrance.
