“…It has reported the reducing capability of iron in seeds (55.3 ± 1.6 mg ET/100 g of dry sample) and germinated seeds (122 ± 11.1 mg ET/100 g of dry sample respectively) of Amaranthus caudatus L., without specifying the range; in which differences were observed in the reductive capacity of iron between seeds and germinated seeds, increasing to 2.2 times. 23 In our report, we can see that in general, the germinated increased iron reducing capacity 1.7 times for variety Oscar Blanco and 2.5 times for variety Taray.…”

Introduction: The objective of this study was to determine the antioxidant activity of four varieties of germinated seeds of Centenario, Cristalino, Oscar Blanco and Taray of Amaranthus caudatus L. compared to non-germinated seeds. Material and Methods: The determination of total phenols was carried out by using Folin-Ciocalteu, total flavonoids by the method of aluminum chloride and the antioxidant activity by the methods of DPPH, ABTS and FRAP. Results: Cristalino variety had the highest germination (3.0 cm of height) and all varieties had a 50% germination rate. Cristalino and Taray varieties had the highest content of total phenolics (GAE 32.92 and 35.00 mg/g sample), Cristalino variety had higher content of flavonoids (580.95 mg QE/g) (P < 0.05); Cristalino and Taray varieties showed greater scavenging activity of DPPH radical (151.85 and 151.38 mg TE/g sample), ABTS (178.09 and 180.18 mg TE/g sample); and reducing capacity of the ferric ion (FRAP) (132.75 and 136.42 mg TE/g of sample). Conclusion: Sprouts of Cristalino and Taray varieties had higher antioxidant activity than non-germinated seeds and they are directly related to higher content of total phenols and flavonoids.

Sprouts and Microgreens: Trends, Opportunities, and Horizons for Novel Research

Sprouts and microgreens have attracted tremendous interest across multiple disciplines in recent years. Here, we critically review the most recent advances to underscore research prospects and niches, and related challenges, not yet addressed or fully pursued. In particular, we report a number of themes that merit special attention as a result of their relevance to plant science, nutrition, health, and zootechnics: (1) species not yet or inadequately investigated, such as wild plants, and fruit tree strains; (2) abiotic and biotic factors, and biostimulants, for elicitation strategies and metabolic engineering; (3) sanitization and processing technologies to obtain high-quality products; (4) digestive fate and impact of bioactive elements, antinutrients, and allergens on human nutrition; (5) experimental challenges to researching health benefits; (6) the opportunity to generate natural product libraries for drug discovery; and (7) sprouts in animal feeding to improve both animal health and the nutritional value of animal products for the human diet. The convergence of different themes involving interdisciplinary competencies advocate fascinating research pursuits, for example, the elicitation of metabolic variants to generate natural product collections for identification and selection of bioactive chemicals with a role as nutraceuticals, key constituents of functional foods, or interactive partners of specific drugs.

“…Only one study has demonstrated the ACE inhibitory capacity of a partially purified 7S-glob subjected to a simulated DGI, with this activity being similar to that of the 11S-glob digests (EC 50 0.17 ± 0.03 mg/ml and 0.17 ± 0.01mg/ml, respectively) (Quiroga et al, 2012). Aphalo et al (2015) reported the ACE inhibitory activity of amaranth sprouts and demonstrated that this activity increases after a simulated DGI (IC 50 0.26 ± 0.07 mg/ml). Vilcacundo et al (2019) have recently subjected a protein concentrate of A. caudatus to a gastrointestinal digestion process using the protocol published by Minekus et al (2014) and analyzed the potential multi-functionality of the released peptides in each digestion stage.…”

Amaranth is an ancestral crop used by pre-Columbian cultures for 6000 to 8000 years. Its grains have a relevant chemical composition not only from a nutritional point of view but also due to the contribution of components with good techno-functional properties and important potential as bioactive compounds. Numerous studies have shown that amaranth storage proteins possess encrypted sequences that, once released, exhibit different physiological activities. One of the most studied is antihypertensive activity. This review summarizes the progress made over the last years (2008-2020) related to this topic. Studies related to inhibition of different enzymes of the Renin-Angiotensin-Aldosterone system, in particular Angiotensin Converting Enzyme (ACE) and Renin, as well as those referring to potential modulation mechanisms of tissue or local Renin-Angiotensin-Aldosterone system, are analyzed, including in silico, in vitro, in vivo, and ex vivo assays. Furthermore, the potential use of these bioactive peptides or products containing them, in the elaboration of functional food matrices is discussed. Finally, the most relevant conclusions and future requirements in research and development of food products are presented.
