Agar (pronounced , sometimes ) or agar-agar is a jelly-like substance, obtained from red algae.Agar is a mixture of two components: the linear polysaccharide agarose, and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae, and is released on boiling. These algae are known as agarophytes, and belong to the Rhodophyta (red algae) phylum.Agar has been used as an ingredient in desserts throughout Asia, and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative, an appetite suppressant, a vegetarian substitute for gelatin, a thickener for soups, in fruit preserves, ice cream, and other desserts, as a clarifying agent in brewing, and for sizing paper and fabrics.The gelling agent in agar is an unbranched polysaccharide obtained from the cell walls of some species of red algae, primarily from tengusa (Gelidiaceae) and ogonori (Gracilaria). For commercial purposes, it is derived primarily from ogonori. In chemical terms, agar is a polymer made up of subunits of the sugar galactose.

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.

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.
