Special Issue Information

Dear Colleagues,

Agrifood waste and byproducts are pervasive, with various environmental, economic, and societal issues. However, they are an abundant source of natural and low-cost biomolecules, including carbohydrates, lipids, proteins, and phenolics, with great potential for new added-value applications in different industries. Therefore, the efficient utilization of agrifood waste/byproducts will contribute to reduce their environment concerns while allowing for the generation of value‑added biomolecules for food and/or packaging industries following sustainability and circular economy concepts.

This Special Issue aims to provide a research status regarding the development of value‑added products from food waste/byproducts filling the gap between research and industrial applications. The Guest Editors of this Special Issue welcome submissions related to the recovery and characterization of valuable biomolecules from agrifood waste/byproducts and their exploitation in food and non-food applications. This includes the development of food formulations with improved nutritional, technological, and/or sensory properties and the application of agrifood waste/byproducts as feedstocks for biobased/biodegradable packaging applications. Research and review articles, as well as short communications, are welcome.

Abstract
The volatile composition of Paulownia Shan tong (Fortunei × Tomentosa) essential oil isolated by steam distillation (yielding 0.013% v/w) from flowers (forestry wastes) was investigated by gas chromatography–mass spectrometry. Thirty-one components were identified, with 3-acetoxy-7, 8-epoxylanostan-11-ol (38.16%), β-monoolein (14.4%), lycopene, [...] Read more.
The volatile composition of Paulownia Shan tong (Fortunei × Tomentosa) essential oil isolated by steam distillation (yielding 0.013% v/w) from flowers (forestry wastes) was investigated by gas chromatography–mass spectrometry. Thirty-one components were identified, with 3-acetoxy-7, 8-epoxylanostan-11-ol (38.16%), β-monoolein (14.4%), lycopene, 1,2-dihydro-1-hydroxy- (10.21%), and 9,12-octadecadienoic acid, 2-phenyl-1,3-dioxan-5-yl ester (9.21%) as main compounds. In addition, molecular docking was employed to identify potential protein targets for the 31 quantified essential oil components. Inhibition of these targets is typically associated with antibacterial or antioxidant properties. Molecular docking revealed that six of these components, namely, 13-heptadecyn-1-ol, ascabiol, geranylgeraniol, anethole, and quinol dimethyl ether, outperformed the native ligand (hypoxanthine) of xanthine oxidase in terms of theoretical binding affinity, therefore implying a significant in silico inhibitory potential against xanthine oxidase. These findings suggest that the essential oil extracted from Paulownia Shan tong flowers could be valuable for developing protein-targeted antioxidant compounds with applications in the food, pharmaceutical, and cosmetic industries.
