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.

DISODIUM CITRATE, more properly, disodium hydrogen citrate, is an acid salt of citric acid with the chemical formula Na2C6H6O7. It is used as an antioxidant in food and to improve the effects of other antioxidants. It is also used as an acidity regulator and sequestrant. Typical products include gelatin, jam, sweets, ice cream, carbonated beverages, milk powder, wine, and processed cheeses.

Guar gum (E412) is a natural food additive derived from guar beans.

This white, odorless powder is valued for its remarkable thickening and stabilizing properties, making it a common ingredient in various food products, including sauces, dressings, and ice creams.

When used in moderation, guar gum is considered safe for consumption, with no known adverse health effects.

Pectins (E440) are natural carbohydrates, predominantly found in fruits, that act as gelling agents in the food industry, creating the desirable jelly-like texture in jams, jellies, and marmalades.

Pectins stabilize and thicken various food products, such as desserts, confectioneries, and beverages, ensuring a uniform consistency and quality.

Recognized as safe by various health authorities, pectins have been widely used without notable adverse effects when consumed in typical dietary amounts.
