Biopolymers are widely distributed in nature and have a wide variety of biological properties and applications. Chia (Salvia hispanica L.) is an herbaceous plant that belongs to the Lamiaceae family, which when in contact with water exude the fraction of soluble fiber in the form of mucilage. In view of the above, this study aims to provide an overview of the characteristics and applications of chia mucilage that make it a biopolymer of industrial interest. The data collection was carried out in the databases: SciELO (Scientific Electronic Library Online), Science Direct, MDPI, Wiley Online Library, Springer and Periodical capes using the following descriptors: “Chia Seed Mucilage”, “Technological Properties”, “Biological Activities”, and “Applications” in alone and in association. After the critical analysis of the selected articles, it was possible to conclude that the chia mucilage has numerous and unique physical-chemical, chemical and technological properties. Applications in the food field are among the most used in view of the industrial perspective. However, the infinite potential that this biomaterial has for the pharmaceutical and agricultural industries is undeniable.
