Natural cocoa powder is cocoa beans in the process of processing into cocoa powder does not add any additives produced by the light brown cocoa powder; and alkalized cocoa powder is in the cocoa beans processing process by adding the edible alkali, so as to adjust the ph value Purpose, while the color of cocoa powder also deepened, the aroma than the natural cocoa powder and more. This is different from the processing process, the general people can not distinguish between the following from the use and appearance and other aspects of comparison. Natural cocoa powder color than the alkalinity cocoa powder lighter, the aroma is not as good as alkalization cocoa powder thick. In use, the alkalization of cocoa powder to use a wide range. In general, natural cocoa powder is not used for the production of liquid products, because the solubility of about 30%; alkalized cocoa powder can be used for any food production, but also direct blunt. Because the alkalization of cocoa powder is higher than the cost of natural cocoa powder, therefore, the general food manufacturers if the production of solid products are basically natural cocoa powder; and the production of liquid milk, beverages and other liquid products with alkalized cocoa powder. Chocolate on the market are basically produced with natural cocoa powder, and chocolate cream tea is produced with alkaline powder. Natural cocoa powder and alkalized cocoa powder there is an important difference, that is, PH value is different. Natural cocoa powder PH value is generally between 5.0 to 5.8; alkalizing cocoa powder PH value is generally between 6.2 to 7.5.
