Assessment of the Phytochemical and Nutrimental Composition of Dark Chia Seed (Salvia hispanica L.)

Chia seeds are rich sources of different macro and micronutrients associated with health benefits; thus, they may be considered as a functional food. However, the composition depends on the variety, origin, climate and soil. Here, we show a comprehensive characterization of extractable and non-extractable phenolic compounds of dark chia seed Salvia hispanica L. using high-performance liquid chromatography-electrospray ionization-quadrupole time-of-flight (HPLC-ESI-QTOF) and discuss potential health benefits associated with the presence of a number of nutritional and bioactive compounds. We report that dark chia from Jalisco is a high-fiber food, containing omega-3 polyunsaturated fatty acids, essential amino acids (phenylalanine and tryptophan), and nucleosides (adenosine, guanidine and uridine), and rich in antioxidant phenolic compounds, mainly caffeic acid metabolites. Our data suggest that chia seeds may be used as ingredients for the development of functional foods and dietary supplements.

Automated summary

Chia seeds are rich sources of various macro and micronutrients associated with health benefits, making them potential functional foods. The composition of chia seeds varies depending on factors such as variety, origin, climate, and soil. Studies have shown that dark chia seeds from Mexico contain high levels of fiber, omega-3 polyunsaturated fatty acids, essential amino acids, and antioxidant phenolic compounds, suggesting their potential use in the development of functional foods and dietary supplements.
