This study showed the eliciting effect of aqueous extracts from Ascophyllum nodosum on development Eruca sativa microgreens in a quartz-based substrate. There is no information literature impact its use quality, bioactive compound content, and nutritional value arugula microgreens. Assays that have been made include following: total phenolic content (TPC), flavonoid (TFV), enzymes such as phenylalanine ammonia (PAL) polyphenol oxidase (PPO), involved scavenging reactive oxygen species catalase (CAT) superoxide dismutase (SOD). The antioxidant activity against DPPH (2,2-diphenyl-1-picrylhydrazyl) was also evaluated. increased significantly after an application A. to greatest increase (89%) (82%) observed at concentration 2.5%. highest CAT (68.2%), SOD (25%), PAL (13-fold), PPO (84.2%) with 5% extract. In conclusion, algae affects TPC TFV, activity, PAL, PPO, SOD, studied. By prioritising organic environmentally friendly extracts, growers can contribute more sustainable healthier food system, especially case production

The Phytonutrient Content and Yield of Brassica Microgreens Grown in Soilless Media with Different Seed Densities

Horticulturae, Год журнала: 2023, Номер 9(11), С. 1218 - 1218

Microgreens are increasingly valued by consumers for their phytonutritional benefits. There is limited information to growers on the influence of growth media and seed density antioxidant properties Brassica microgreens. Therefore, study was conducted determine effect seedling (Hygromix, Promix, TS1) (4, 8, 12 seeds per cavity) morphological parameters, yield, color, components, activities in radish (Raphanus sativus), cabbage (Brassica oleracea), rocket (Eruca sativa) Fourteen days after seeding, Promix at a cavity improved yield radish, cabbage, Irrespective density, all three microgreens grown TS1 had higher leaf nitrogen, phosphorus, calcium content. Interaction effects Hygromix x densities were more pronounced (DPPH FRAP). These differences could be due physical medium. Vitamin C total glucosinolate 4 cavity. Twelve medium whereas phytochemicals most likely growing media, followed mineral content low

Evaluation of Bioactive Compounds and Antioxidant Activity of Green and Red Kale (Brassica oleracea L. var. acephala) Microgreens Grown Under White, Red, and Blue LED Combinations

Agronomy, Год журнала: 2024, Номер 14(11), С. 2454 - 2454

Microgreens have great potential for improving the nutritional value of human diets, as well constituting a promising dietary option preventing chronic disease. Light-emitting diodes (LEDs) are commercially used light source to improve growth microgreens, nutrient and bioactive compound accumulation. Here, we provide first report phenolic compound, chlorophyll carotenoid pigment, fiber contents red green kale microgreens grown in chamber under white LEDs combined with or blue light. Significant differences response phytocompounds between its combination were determined. These studies showed that positively influenced accumulation compounds, which consequently determined high antioxidant activity. On contrary, LED lights most suitable carotenoids chlorophylls, including b, Klason lignin. results suggest use can increase concentration compounds thus may enhance their health-promoting potential.

Glucoraphanin in Keimsaaten

Zeitschrift für Phytotherapie, Год журнала: 2023, Номер 44(06), С. 257 - 267

Опубликована: Дек. 1, 2023

Zusammenfassung Als eine vielversprechende Quelle für bioaktive pflanzliche Sekundärstoffe gelten Keimsprossen von Kreuzblütlerpflanzen (Familie: Brassicaceae). Vor allem das in Brokkolisprossen höheren Konzentrationen vorkommende Glucoraphanin ist als bioaktiver Naturstoff besonderer Bedeutung. gehört zur Stoffklasse der Glucosinolate (Senfölglucoside) und stellt Prodrug Sulforaphan (1-Isothiocyanato-4-methylsulfinylbutan) dar, zahlreichen Studien antikarzinogene bzw. chemopräventive Effekte gezeigt werden konnten. Zur Optimierung täglichen Aufnahme Glucosinolaten wird die eigene Anzucht Sprossen immer beliebter Vielzahl diesbezüglicher Brokkoli-Keimsaaten hierfür heute am Markt verfügbar. In diesem Zusammenhang wurden vorliegenden Studie Glucosinolatmuster 48 handelsüblichen Kreuzblütlersamen untersucht, davon Hälfte (24 Proben) mit Deklaration „Brokkoli“. 15 untersuchten Samenproben konnte deutlichen Mengen nachgewiesen werden. Lediglich 9 dieser Samenmuster stammen laut Brokkoli, alle übrigen leiten sich anderen Varietäten Stamm-Art Brassica oleracea ab. Dies analytisch eindeutig über jeweiligen Glucosinolat-Fingerprints mittels U(H)PLC CE belegt Die Ergebnisse belegen, dass vielen Fällen (15 24 trotz „Brokkoli“ untersuchte Saatgut kein Brokkoli typisches Glucosinolatprofil nachweisbar nur wenig oder bestimmbar war. Verbraucher Patienten unbefriedigende Situation bewertet.
