Abstract
Nowadays, people consume foods that not only cover the nutritional requirements, but that also show biological activity and are healthy, natural, and convenient.
Stems have been proven to possess components with valuable biological activities: anti-inflamatory, antioxidant, antiulcerogenic, hypoglycemic, and so forth.
This study evaluated the bio-functional effects of consuming tortillas or bars (filled with prickly pear fruit jam) supplemented or not supplemented with nopal dietary fiber.
The addition of nopal increased the fiber and polyphenols content in both tortillas (16.67%, 2.33 mg QE/L) and bars (13.79%, 1.99 mg QE/L). Furthermore, the trolox equivalent antioxidant capacity (TEAC, 1.47 mmol/L), polyphenols (7.67 mg QE/L), and vitamin C (77.91 μmol/L) showed increased levels in the plasma of volunteers after intake.
Also, lower levels of glucose (4.43 mmol/L), total cholesterol (mmol/L), LDL (1.96 mmol/L), and triglycerides (1.54 mmol/L) were observed in plasma after the supplementation scheme with nopal-based tortilla, while GSH:GSSG ratio in erythrocytes was higher.
The results suggested that the intake of nopal-based tortillas with high fiber and antioxidant compound content can help to improve the overall oxidative status in healthy humans, which can reduce the risk of some chronic diseases.
In addition, these products showed suitable physicochemical characteristics to be marketed.
