Chia seed mucilage: Extraction methods and potential application in food matrix
Resumo
Chia (Salvia hispanica L.) is a herbaceous plant native to southern Mexico and northern Guatemala, with a high nutrient content and technological properties. Currently, its seed has stood out, since it has 5 to 6% soluble fibers, which are exuded when the seeds are placed in water, forming a transparent capsule around the seeds. The extraction of chia mucilage involves three processes: hydration, extraction, and drying. The amount of mucilage extracted can be affected by several factors related to extraction conditions, such as chia ratio: water, extraction temperature, hydration time, agitation, and separation. In addition, its incorporation into food contributes to sensory and physical characteristics, with regard to texture, stabilization, formation of gels and emulsions, volume, inhibition of syneresis among other factors. Thus, the present study aimed to analyze studies that differ with regard to the extraction methodology, in addition to the application of this gel in food products. The review was carried out in July 2023, on the Periódicos CAPES electronic platform of scientific articles, which used chia mucilage as a substitute for commercial additives in foods. The selected articles were published between 2018 and 2023 and the following terms were used for the search: "mucilage", "chia", "applications". In the studies analyzed, it was possible to observe a variation in yield of 3.4 to 8.5% depending on the methodology used by the authors, which shows the relationship in the change of the variables: seed/water, time, temperature, and use of ultrasound. Regarding the application of mucilage in food formulation, the analyzed studies provided good results in the physicochemical and sensory characteristics of food products.
