Food coloring, a versatile ingredient that transforms dishes into vibrant masterpieces, has been a staple in kitchens worldwide for centuries. One of the most popular brands in this realm is R.F. Kuenzli & Co., often abbreviated as RFK. This article delves into the world of RFK food coloring, exploring its history, products, uses, and safety aspects.
History of RFK Food Coloring
RFK's journey began in 1888 when Robert F. Kuenzli established his company in New York City. Initially, RFK was a manufacturer of pharmaceuticals and cosmetics. However, it was their foray into food coloring in the early 1900s that cemented their legacy. Today, RFK is a leading supplier of food coloring, serving both the foodservice and consumer markets.
RFK Food Coloring Products
RFK offers a wide array of food coloring products, catering to diverse culinary needs. Their portfolio includes:

- Liquid Food Colors: These are concentrated, water-based colors that provide intense hues. They are perfect for icings, frostings, and beverages.
