Special Issue Information

Dear Colleagues,

Phytonutrients are natural bioactive compounds obtained from plants. Foods and by-products are composed of some phytonutrients, in addition to vitamins, polyphenols, phytosterols, proteins, complex carbohydrates, minerals, and dietary fibres. Almost all of the phytonutrients from foods and its by-products have anti-inflammatory, antibacterial, and antioxidant properties, along with other specific health benefits, such as antiviral, hormone regulation, nerve conduction, and immunomodulatory effects. The bioavailability of phytonutrients is affected by the processing method and the determination method. Moreover, bioactive compounds extracted from plant or food by-products are combined with food preservation technologies, such as active packaging films and non-thermal sterilization technologies (pulsed electric fields, high-pressure processing, ultrasonic treatment and so on), can prolong the food shelf-life and storage period of food quality.

The aim of this Special Issue is to investigate the characterization and quantification of phytonutrients in foods and its by-products, such as tea, coffee, mushroom, and peel and seed of fruits. The characters include vitamin, polyphenol, phytosterol, protein, complex carbohydrate, and dietary fibre, etc. Influence factors such as resources of plant, processing methods, and determination methods of phytonutrients will also be explored. Additionally, phytonutrients extracted from other vegetables and fruits are welcome.

Abstract

The present work is focused on the development of an analytical platform to elucidate the metabolic pathway of PTSO from onion, an organosulfur compound well-known for its functional and technological properties and its potential application in animal and human nutrition. This analytical platform consisted of the use of gas chromatography–mass spectrometry (GC-MS) and ultra-high performance liquid chromatography quadrupole with time-of-flight MS (UHPLC-Q-TOF-MS) in order to monitor volatile and non-volatile compounds derived from the PTSO. For the extraction of the compounds of interest, two different sample treatments were developed: liquid–liquid extraction (LLE) and salting-out assisted liquid–liquid extraction (SALLE) for GC–MS and UHPLC-Q-TOF-MS analysis, respectively. Once the analytical platform was optimised and validated, an in vivo study was planned to elucidate PTSO metabolisation, revealing the presence of dipropyl disulfide (DPDS) in liver samples with concentrations between 0.11 and 0.61 µg g⁻¹. The DPDS maximum concentration in the liver was observed at 0.5 h after the intake. DPDS was also present in all plasma samples with concentrations between 2.1 and 2.4 µg mL⁻¹. In regard to PTSO, it was only found in plasma at times above 5 h (0.18 µg mL⁻¹). Both PTSO and DPDS were excreted via urine 24 h after ingestion. Full article

Abstract

Herbal tea has numerous biological activities and exhibits broad benefits for human health. In China, the flower buds of Lyonia ovalifolia are traditionally processed as herbal tea, namely White Que Zui tea (WQT). This study was aimed to evaluate the effect of ultra-high hydrostatic pressure (UHHP) pretreatment on the chemical constituents and biological activities of free, esterified, and insoluble-bound phenolic fractions from WQT. A total of 327 chemical constituents were identified by a quasi-targeted metabolomics analysis. UHHP pretreatment extremely inhibited reactive oxygen species (ROS) production and cell apoptosis in H₂O₂-induced HepG2 cells, and it increased the activities of intracellular antioxidant enzymes (SOD and CAT) and GSH content in different phenolic fractions from WQT. In addition, after UHHP pretreatment, the anti-inflammatory effects of different phenolic fractions from WQT were improved by inhibiting the production of nitric oxide (NO) and pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β) in LPS-induced RAW264.7 cells. Thus, the UHHP method might be a potential pretreatment strategy for improving the bioavailability of phytochemicals from natural plants. Full article

Abstract

Vinegar residue (VR) is a typical organic solid waste in Chinese cereal vinegar production. It is characterized by high yield, high moisture and low pH and is rich in lignocellulose and other organic matter. To avoid the environmental pollution caused by VR, it should be properly treated. The industry’s existing treatment processes, landfills and incineration, cause secondary pollution and waste of resources. Therefore, there is an urgent demand for environmentally friendly and cost-effective resource recovery technologies for VR. To date, a considerable amount of research has been performed in the area of resource recovery technologies for VR. This review summarizes the reported resource recovery technologies, mainly anaerobic digestion, feed production, fertilizer production, high-value product production and soil/water remediation. The principles, advantages and challenges of these technologies are highlighted. Finally, as a future perspective, a cascade and full utilization model for VR is proposed by considering the inherent drawbacks and economic-environmental feasibility of these technologies.
