- Starch: A polysaccharide present in vegetation, used as a thickener and gelling agent.
- Cellulose: A structural polysaccharide present in plant mobile partitions, used as a stabilizer and emulsifier.
- Pectin: A polysaccharide present in culmination, used as a gelling agent and thickener.
Proteins
Proteins are massive molecules composed of amino acids. They may be able to shape gels, foams, and emulsions. Examples of proteins used as meals hydrocolloids come with:
- Gelatin: A protein derived from collagen, used as a gelling agent.
- Egg white proteins: Used as foaming brokers and emulsifiers.
- Soy proteins: Used as gelling brokers and emulsifiers.
Gums
Gums are herbal or changed polysaccharides which are soluble in water. They may be able to shape viscous answers and are used as thickeners, stabilizers, and emulsifiers. Examples of gums come with:
- Xanthan gum: A polysaccharide produced through micro organism, used as a thickener and stabilizer.
- Guar gum: A polysaccharide derived from guar beans, used as a thickener and stabilizer.
- Gum arabic: A polysaccharide derived from the acacia tree, used as an emulsifier and stabilizer.
