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.

SORBIC ACID, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative. It has the chemical formula CH3(CH)4CO2H.

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.

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.

Xanthan gum (E415) is a natural polysaccharide derived from fermented sugars, often used in the food industry as a thickening and stabilizing agent.

This versatile food additive enhances texture and prevents ingredient separation in a wide range of products, including salad dressings, sauces, and gluten-free baked goods.

It is considered safe for consumption even at high intake amounts.

Sorbitol (), less commonly known as glucitol (), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the aldehyde group to a hydroxyl group. Most sorbitol is made from corn syrup, but it is also found in nature, for example in apples, pears, peaches, and prunes. It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses.

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.

Diphosphates (E450) are food additives often utilized to modify the texture of products, acting as leavening agents in baking and preventing the coagulation of canned food.

These salts can stabilize whipped cream and are also found in powdered products to maintain their flow properties. They are commonly present in baked goods, processed meats, and soft drinks.

Derived from phosphoric acid, they're part of our daily phosphate intake, which often surpasses recommended levels due to the prevalence of phosphates in processed foods and drinks.

Excessive phosphate consumption is linked to health issues, such as impaired kidney function and weakened bone health. Though diphosphates are generally regarded as safe when consumed within established acceptable daily intakes, it's imperative to monitor overall phosphate consumption to maintain optimal health.

Sodium carbonates (E500) are compounds commonly used in food preparation as leavening agents, helping baked goods rise by releasing carbon dioxide when they interact with acids.

Often found in baking soda, they regulate the pH of food, preventing it from becoming too acidic or too alkaline. In the culinary world, sodium carbonates can also enhance the texture and structure of foods, such as noodles, by modifying the gluten network.

Generally recognized as safe, sodium carbonates are non-toxic when consumed in typical amounts found in food.

Sodium hydrogen carbonate, also known as E500ii, is a food additive commonly used as a leavening agent.

When added to recipes, it releases carbon dioxide gas upon exposure to heat or acids, causing dough to rise and resulting in a light, fluffy texture in baked goods.

It is generally recognized as safe (GRAS) by regulatory authorities when used in appropriate quantities and poses no significant health risks when consumed in typical food applications.
