Disclosed are processes for preparing dry or powder dairy compositions having low lactose contents and containing polyphenol compounds. The resultant dry or powder dairy compositions can be used to form reconstituted fluid dairy products, which can have improved organoleptic properties, such as less cooked flavor, sulfur odor, and brown color.

Natural blue colorant compositions and methods of use thereof are provided. The colorant compositions include at least one acylated anthocyanin, such as a diacylated anthocyanin. The colorant composition can further include a buffer solution having a pH from about 6.0 to about 8.0 and a metal ion or salt form thereof. The colorant compositions can be derived from a natural product and provide a stable, blue colorant that can be used in food products.
