Chocolate whether emulsifying agents are added. Different manufacturers develop their own "signature" blends based on the above formulas, but varying proportions of the different constituents are used. The finest, plain dark chocolate couvertures contain at least 70% cocoa (both solids and butter), whereas milk chocolate usually contains up to 50%. High-quality white chocolate couvertures contain only about 35% cocoa butter. Producers of high-quality, small-batch chocolate argue that mass production produces bad-quality chocolate. Some mass-produced chocolate contains much less cocoa (as low as 7% in many cases), and fats other than cocoa butter. Vegetable oils and artificial vanilla flavor are often used
Milk basic protein Milk basic protein Milk basic protein (MBP) is a fraction of whey protein found in milk. Separated from milk through the process of fractionation, it is a functional compound and consists of several milk proteins which are biologically active. The composition is approximately 54% lactoferrin and 41% lactoperoxidase, with other active proteins, such as Cyastin C and high mobility group-like proteins, making up the remainder of the fraction. MBP has been evaluated for safety and is intended for use as a dietary ingredient. It is approved in Japan as a functional food ingredient in tofu and nattō. Active substances in
