LUTEIN is a xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is extracted from the petals of African marigold (Tagetes erecta). It is approved for use in the EU and Australia and New Zealand. In the United States lutein may not be used as a food coloring for foods intended for human consumption, but can be added to animal feed.

Gum arabic, also known as acacia gum, arabic gum, gum acacia, acacia, Senegal gum and Indian gum, and by other names, is a natural gum consisting of the hardened sap of various species of the acacia tree. Originally, gum arabic was collected from Acacia nilotica which was called the "gum arabic tree"; in the present day, gum arabic is collected from acacia species, predominantly Acacia senegal and Vachellia (Acacia) seyal; the term "gum arabic" does not indicate a particular botanical source. In a few cases so‐called "gum arabic" may not even have been collected from Acacia species, but may originate from Combretum, Albizia or some other genus. Producers harvest the gum commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia—though it is historically cultivated in Arabia and West Asia. Gum arabic is a complex mixture of glycoproteins and polysaccharides. It is the original source of the sugars arabinose and ribose, both of which were first discovered and isolated from it, and are named after it. Gum arabic is soluble in water. It is edible, and used primarily in the food industry as a stabilizer, with EU E number E414. Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries, though less expensive materials compete with it for many of these roles. While gum arabic is now produced throughout the African Sahel, it is still harvested and used in the Middle East.

Glycerol ester of wood rosin, also known as glyceryl abietate or ester gum, is an oil-soluble food additive (E number E445). The food-grade material is used in foods, beverages, and cosmetics to keep oils in suspension in water, and its name may be shortened in the ingredient list as glycerol ester of rosin. It is also used as an ingredient in the production of chewing-gum and ice cream. Similar, less pure materials (glycerol ester of gum rosin) are used as a component of certain low-cost adhesives.To make the glycerol ester of wood rosin, refined wood rosin is reacted with glycerin to produce the glycerol ester. Glycerol ester of wood rosin is an alternative to brominated vegetable oil in citrus oil-flavored soft drinks. In some cases, both ingredients are used together.
