Cochineal extract or carmine (E120) is a natural red colorant derived from the dried bodies of the female cochineal insect.

It is widely used to impart a pink, red, or purple hue to various food and beverage products, including yogurts, ice creams, confectionery, and fruit juices.

Although it is a natural additive, E120 is known to cause severe allergic reactions, including anaphylaxis, in some individuals. It is also not suitable for vegetarians or vegans due to its insect origin.

Indigo carmine, or 5,5′-indigodisulfonic acid sodium salt, is an organic salt derived from indigo by sulfonation, which renders the compound soluble in water. It is approved for use as a food colorant in the U.S and E.U., It has the E number E132. It is also a pH indicator.

β-Carotene is an organic, strongly colored red-orange pigment abundant in plants and fruits. It is a member of the carotenes, which are terpenoids (isoprenoids), synthesized biochemically from eight isoprene units and thus having 40 carbons. Among the carotenes, β-carotene is distinguished by having beta-rings at both ends of the molecule. β-Carotene is biosynthesized from geranylgeranyl pyrophosphate.β-Carotene is the most common form of carotene in plants. When used as a food coloring, it has the E number E160a. The structure was deduced by Karrer et al. in 1930. In nature, β-carotene is a precursor (inactive form) to vitamin A via the action of beta-carotene 15,15'-monooxygenase.Isolation of β-carotene from fruits abundant in carotenoids is commonly done using column chromatography. It can also be extracted from the beta-carotene rich algae, Dunaliella salina. The separation of β-carotene from the mixture of other carotenoids is based on the polarity of a compound. β-Carotene is a non-polar compound, so it is separated with a non-polar solvent such as hexane. Being highly conjugated, it is deeply colored, and as a hydrocarbon lacking functional groups, it is very lipophilic.

Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally, it is sourced from ilmenite, rutile and anatase. It has a wide range of applications, including paint, sunscreen and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million metric tons. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and the oxide has been valued at $13.2 billion.

Lecithins are natural compounds commonly used in the food industry as emulsifiers and stabilizers.

Extracted from sources like soybeans and eggs, lecithins consist of phospholipids that enhance the mixing of oil and water, ensuring smooth textures in various products like chocolates, dressings, and baked goods.

They do not present any known health risks.

Citric acid is a natural organic acid found in citrus fruits such as lemons, oranges, and limes.

It is widely used in the food industry as a flavor enhancer, acidulant, and preservative due to its tart and refreshing taste.

Citric acid is safe for consumption when used in moderation and is considered a generally recognized as safe (GRAS) food additive by regulatory agencies worldwide.

Tragacanth is a natural gum obtained from the dried sap of several species of Middle Eastern legumes of the genus Astragalus, including A. adscendens, A. gummifer, A. brachycalyx, and A. tragacantha. Some of these species are known collectively under the common names "goat's thorn" and "locoweed". The gum is sometimes called Shiraz gum, shiraz, gum elect or gum dragon. The name derives from the Greek words tragos (meaning "goat") and akantha ("thorn"). Iran is the biggest producer of this gum. Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap that is drained from the root of the plant and dried. The gum seeps from the plant in twisted ribbons or flakes that can be powdered. It absorbs water to become a gel, which can be stirred into a paste. The major fractions are known as tragacanthin, highly water soluble as a mucilaginous colloid, and the chemically related bassorin, which is far less soluble but swells in water to form a gel. The gum is used in vegetable-tanned leatherworking as an edge slicking and burnishing compound, and is occasionally used as a stiffener in textiles. The gum has been used historically as a herbal remedy for such conditions as cough and diarrhea. As a mucilage or paste, it has been used as a topical treatment for burns. It is used in pharmaceuticals and foods as an emulsifier, thickener, stabilizer, and texturant additive (E number E413). It is the traditional binder used in the making of artists' pastels, as it does not adhere to itself the same way other gums (such as gum arabic) do when dry. Gum tragacanth is also used to make a paste used in floral sugarcraft to create lifelike flowers on wires used as decorations for cakes, which air-dries brittle and can take colorings. It enables users to get a very fine, delicate finish to their work. It has traditionally been used as an adhesive in the cigar-rolling process used to secure the cap or "flag" leaf to the finished cigar body.Gum tragacanth is less common in products than other, usually cheaper, gums, such as gum arabic or guar gum. Different gums tend to be interchangeable across many uses, and production of tragacanth is far outpaced by these for reasons of economy, trade, agriculture and history, while tragacanth is mostly produced in traditional locations. However, gums are used in varied circumstances and there are many situations where tragacanth is considered superior. Common substitutions are methyl cellulose, sometimes marketed as "substitute gum tragacanth" in the food industry, and gum karaya. Gum karaya, also called "Indian tragacanth" or simply "tragacanth", might be fully or partially substituted for what appears to be genuine tragacanth. Gum tragacanth is also used in incense-making as a binder to hold all the powdered herbs together. Its water solubility is ideal for ease of working and an even spread, and it is one of the stronger gums for holding particles in suspension. Only half as much is needed, compared to gum arabic or something similar.In Saudi Arabia, a mixture of hydrated Tragacanth and ground dried Ziziphus spina-christi is used as a natural hair shampoo that is believed to promote hair growth.

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 (; also called glycerine or glycerin; see spelling differences) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant and in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
