Seeds of Salvia hispanica L., "chia" as a source of macronutrients, dietary fiber and minerals

Abstract

The purpose of this research was to determine the content of macronutrients, dietary fiber, moisture and minerals in Salvia hispanica L.’s seeds. Moisture determination was carried out in a conventional oven until constant weight, proteins by the kjeldahl method, lipids by soxhlet, dietary fiber by the enzymatic gravimetric method and minerals by atomic absorption equipment, the anthrone colorimetric method was used for carbohydrates and the caloric value was determined by calculations. From the results, it can be informed that chia`s seeds have a significant content of dietary fiber 41.4 ± 1.20 g/100 g, lipids 22.3 + 0.283 g/100 g, protein 17.2 + 0.436 g/100 g and carbohydrates 8.46 ± 0.085 g/100 g. The minerals founded in greater concentration were potassium 617 ± 26.6 mg/100 g, calcium 532 ± 15.1 mg/100 g, magnesium 81.5 ± 2.25 mg/100 g, iron 10.8 ± 0.636 mg/100 g, in lower concentration sodium 8.97 ± 0.82 mg/100 g and zinc 4.03 ± 0.09 mg/100 g. Chia`s seeds stand out as a source of dietary fiber, potassium, calcium, magnesium and iron. Its low level of sodium makes it suitable for diets with low sodium intake. The consuming of chia seeds could contribute to a varied and healthy diet.
