Special Issue Information

Dear Colleagues,

Plants will publish a Special Issue, called “Valorization of Food Industry By-Products for Applications as Food Additives”. There are significant quantities of by-products generated by food industrial processing that could be a valuable source of different bioactive compounds. These by-products of the primary industry could be reutilized because they represent a rich source of natural compounds to produce high-value-added products for food. All these matrices are now underexploited and so they can be revalued as a natural source of ingredients to be applied in food. Many studies have focused on the reutilization of agroindustrial wastes that are sources of pigments, antimicrobials, fibre, sugars, proteins, oils, antioxidants, vitamins, and organic acids, available at no additional cost. For this Special Issue, the Guest Editor has brought together contributions from a group of outstanding international researchers to produce a valuable resource for researchers, faculty, students, food nutrition and health practitioners, and all those working in the food and nutraceutical industries, especially in the development of functional foods. This Special Issue in Plants will contribute to knowledge of by-products from several aspects, such as valorization, preservative properties, and health effects, including studies of in vivo biological activity of bioactive compounds and nutrients.

Effects of Nigella sativa Oil Fractions on Reactive Oxygen Species and Chemokine Expression in Airway Smooth Muscle Cells

Abstract

Background: many previous studies have demonstrated the therapeutic potential of N. sativa total oil fractions, neutral lipids (NLs), glycolipids (GLs), phospholipids (PLs), and unsaponifiable (IS) in asthma patients. We therefore tested its effect on airway smooth muscle (ASM) cells by observing its ability to regulate the production of glucocorticoid (GC)-insensitive chemokines in cells treated with TNF-α/IFN-γ, and its antioxidative and reactive oxygen species (ROS) scavenging properties. Materials and methods: the cytotoxicity of N. sativa oil fractions was assessed using an MTT assay. ASM cells were treated with TNF-α/IFN-γ for 24 h in the presence of different concentrations of N. sativa oil fractions. An ELISA assay was used to determine the effect of N. sativa oil fractions on chemokine production (CCL5, CXCL-10, and CXCL-8). The scavenging effect of N. sativa oil fractions was evaluated on three reactive oxygen species (ROS), O₂•⁻, OH•, and H₂O₂. Results: our results show that different N. sativa oil fractions used at 25 and 50 µg/mL did not affect cell viability. All fractions of N. sativa oil inhibited chemokines in a concentration-dependent manner. Interestingly, the total oil fraction showed the most significant effect of chemokine inhibition, and had the highest percentage of ROS scavenging effect. Conclusion: these results suggest that N. sativa oil modulates the proinflammatory actions of human ASM cells by inhibiting the production of GC-insensitive chemokines. Full article

Abstract

This study was designed to evaluate the tyrosinase inhibitory effect, in vitro, in vivo, and in silico toxicity of fractions isolated from A. numidica de Lannoy needles. The cytotoxicity of extracts was examined against Artemia salina larvae, while the toxicity of these extracts was tested by acute oral toxicity in mice; by administration of a dose of 2000 mg/kg b.w A. numidica leaves extracts. The blood samples were collected from the eye orbital sinus for further analysis of biochemical parameters. The absorption, distribution, metabolism, elimination, and toxicity (ADMET) properties were identified by the pkCSM web server. The data stated that ethyl acetate (EA) presented strong anti-tyrosinase apt. The results reported that ethyl acetate extract exhibited a strong inhibitory capacity against A. salina larvae with LD₅₀ of 75.004 µg/mL. The data also showed that no mortality occurred, and no toxicity symptoms were observed in mice. The biochemical parameters revealed that both extracts significantly affected the hepatic profile by increasing ALT, AST, and alkaline phosphatase. Histopathological tests also confirmed that both fractions were toxic at this concentration on hepatic and renal tissues, with necrosis observed. The toxicity of molecules in silico revealed no effect on all examined biomolecules.It can be concluded that this plant was toxic on the liver and renal profiles and tissues at the dose studied.

Abstract

Propolis is a natural hive product collected by honeybees from different plants and trees. The collected resins are then mixed with bee wax and secretions. Propolis has a long history of use in traditional and alternative medicine. Propolis possesses recognized antimicrobial and antioxidant properties. Both properties are characteristics of food preservatives. Moreover, most propolis components, in particular flavonoids and phenolic acids, are natural constituents of food. Several studies suggest that propolis could find use as a natural food preservative. This review is focused on the potential application of propolis in the antimicrobial and antioxidant preservation of food and its possible application as new, safe, natural, and multifunctional material in food packaging. In addition, the possible influence of propolis and its used extracts on the sensory properties of food is also discussed. Full article
