Sprouts, mainly from cereals, legumes, and some pseudo-cereals, are rich in nutrients and contain biocompounds, making them attractive for consumption. This research study aimed to develop treatments with UV-C light in soybean and amaranth sprouts and evaluate their effect on biocompounds content, compared with chlorine treatments. UV-C treatments were applied at distances of 3 and 5 cm and times of 2.5, 5, 10, 15, 20, and 30 min, whereas chlorine treatments were applied as immersion in solutions at 100 and 200 ppm for 15 min. Phenolics and flavonoid content were higher in UV-C-treated sprouts than in those treated with chlorine solutions. Ten biocompounds were identified in soybean sprouts, with increasing in apigenin C-glucoside-rhamnoside (105%), apigenin 7-O-glucosylglucoside (237%), and apigenin C-glucoside malonylated (70%) due to UV-C application (3 cm, 15 min); for amaranth sprouts, five biocompounds were identified, with higher contents of p-coumaroylquinic acid (17.7%) after UV-C treatment (3 cm, 15 min). The best treatment to achieve the highest bioactive compounds concentration was UV-C at a distance of 3 cm for 15 min, without significant modification on the color parameters, Hue and chroma. PRACTICAL APPLICATION: UV-C can be used to increase the biocompound content in amaranth and soybean sprouts. Nowadays, there is UV-C equipment available for industrial applications. In this way, sprouts may be maintained as fresh through this physical technology, and they will retain or increase the concentration of health-related compounds.

Edible legume sprouts have been proposed as a promising plant-based source of the enzyme diamine oxidase (DAO), which plays a key role in degrading histamine at an intestinal level and preventing the development of histamine intolerance symptoms. However, the temperature and humidity conditions required for seed germination can also favor the rapid growth of yeast and mold, potentially compromising sprout yield and quality. The aim of this study was to evaluate the influence of different seed disinfection treatments on both the germination rate and DAO enzymatic activity in sprouts of four species.

High copper levels pose a risk to environmental and human health due to their toxicity and widespread industrial application, in which abnormal copper levels are associated with various diseases both in neurodegenerative diseases and plant growth. Thus, a turn-on fluorescent probe BBYD-Cu, based on donor-acceptor type structure, was designed and synthesized with easy preparations. BBYD-Cu can specifically recognized Cu by 2-picolinic ester group, then released the fluorophore to enhance the fluorescent signals.

Modern production-oriented farming has led to a decline in agricultural biodiversity. In Europe, one example of concern is the common hamster , a hibernating rodent once largely distributed in farmlands and now listed as Critically Endangered. The decline of this species is tied to a significant decrease in hamsters' body mass at emergence from hibernation and in reproduction rate.

Selenium-enriched peptides (SePPs) were isolated from Se-enriched soybean sprouts as the selenium (Se) supplement. The preparation of SePPs was optimised, and their Se content, stability during drying, and absorption properties, were examined. The maximum in vitro antioxidant activity of SePPs was achieved after 5 h of alcalase, at 50 °C, pH 9, 3 % substrate concentration, and 5 % enzyme concentration.
