Abstract
- Elicitation is a biotechnological approach to improve phenolic compounds content and antioxidant properties of ready-to-eat functional foods. This study aimed to evaluate the chemical elicitation effects using salicylic acid (SA) and hydrogen peroxide (H <subscript>2</subscript> O <subscript>2</subscript> ) in optimized-germination conditions on seedling vigor, phenolic content, and their antioxidant capacities in vitro and serum and urine of Wistar obese rats. Optimized-germination conditions of 26.5 °C and 178 h produced a 64% of germination and a sprout length of 56 mm. Only, the elicitation with H <subscript>2</subscript> O <subscript>2</subscript> (20 mM) enhanced the germination (75%) and H <subscript>2</subscript> O <subscript>2</subscript> (10 and 20 mM) the sprout length (69 and 59 mm, respectively). In contrast, both elicitors enhanced phenolic contents, being more significant total phenolic compounds content for SA (1 and 2 mM), up to 65.5-73.5%. SA and H <subscript>2</subscript> O <subscript>2</subscript> improved total flavonoids content (36.5-64.1%), ABTS (19.3-61.1%), and DPPH capacities (51-86%), depending on SA and H <subscript>2</subscript> O <subscript>2</subscript> concentration, compared with non-elicited chia sprouts. The QUENCHER antioxidant capacities of elicited chia sprouts increased up to three times more than extracts capacities, principally Q-ABTS, which could be attributed to phenolic bounds to dietary fiber. Rats fed with a high-fat and fructose diet (HFFD) and supplemented with chia sprouts, especially 1-mM SA, improve the obesity-related oxidative stress through an increase of antioxidant capacities, using DPPH and ABTS test, on serum (70-118%) and urine samples (80-116%). These results suggest that chia sprouts elicited with 1-mM SA are a source of antioxidant compounds that can be used to decrease obesity related oxidative stress.<br /> (© 2021.
