Chia mucilage (CM) is an emerging resource in food applications. However, the mechanism of this biopolymer as a stabilizer/emulsifier ingredient has not yet been well defined. A non‐uniform viscoelastic tridimensional network was observed on emulsions with CM, while the surface activity of the CM ingredient has been associated with its protein content. To understand its functionality in food, this review focused on discussing and summarizing the rheological properties of dispersions and emulsions composed of CM under different conditions, such as pH, temperature, salt content, and mucilage content. For example, emulsions and dispersions with CM showed pseudoplastic behavior. An increase in the CM concentration increased the viscosity and the consistency index and decreased the behavior index. The consistency index of dispersions with CM increased with pH. The future evaluation of emulsions and dispersions properties, such as viscoelastic properties and microstructure, is particularly important for the successful use of CM in the food industry. The principal studies have evaluated the use of CM in dairy and meat systems as an emulsifier, stabilizer, or lipid replacer. The nutritional quality of the products with CM was maintained or improved, but sometimes an undesirable darkening was observed. Future evaluation of the cold extraction method of CM might improve the color and overall sensory acceptability of food products with CM. Integrated chia seed processing, including mucilage, oil, and protein extraction could be carried out to make chia seed industrial processing viable. © 2022 Society of Chemical Industry.
