COLORINGS
23. COLORINGS are used in the making of confections, candy in
particular, for two purposes: to make them attractive and to indicate
certain flavors. For instance, candies flavored with wintergreen are
usually colored pink, while those containing peppermint are colored pale
green or are left white. Strawberry and rose flavors are also colored
pink; orange and lemon, their respective shades of yellow; violet,
lavender; and pistachio and almond, green.
24. The substances used for coloring confections are of two general
classes: _vegetable_ and _mineral_, or _chemical_. The vegetable
colorings, like the natural flavorings, are considered to be the most
healthful ones. Some of the chemical colorings are derivatives of coal
tar, just as are the coal-tar flavorings. Cochineal, a red color
extracted from the bodies of cochineal insects, is a coloring matter
much used in the preparation of confections. These coloring materials
may be purchased in several forms. The ones most commonly used come in
the form of liquid or paste, but frequently colorings are to be had in
powder or tablet form.
