Abstract

Several agri-food byproducts represent valuable sources of compounds to be reutilized for nutritional, nutraceutical, and cosmetic purposes. Examples especially comprise byproducts from the processing of fruits such as pomace, because of their richness in nutrients (e.g., fibers) and bioactive compounds (e.g., polyphenols) that can be destined for animal and human use. However, in agreement with the principles of circular economy that are being promoted during the most recent years, other understudied agri-food byproducts of both plant and animal origin are being evaluated to assess their possible reutilization and valorization. In this review, we aim at summarizing the most recent research dealing with the extraction of nutrients and bioactive compounds from agri-food byproducts using innovative and sustainable approaches. Specifically, the review is focused on byproducts generated in large amounts (tons/year) by the food industry of Northeast Italy, namely, honey, red fruits (grapes and berries), and chicory, which are especially of interest for their content in phenolic acids, flavonoids, anthocyanins, and dietary fiber. The potential applications of these byproducts and extracts in cosmetic, nutraceutical, and nutritional fields are also discussed, referring to the published literature, as well as their potential utilization as sources of novel bioactive compounds with pharmacological applications.

Abstract

Tannins are polyphenolic compounds extracted from various tree species and used in variousmapplications such as adhesives, composites, pharmaceuticals, medicines, and food and beverage production (Mubarak et al. 2023). However, tannins, especially condensed tannins, have limited reactivity with wood. Consequently, to effectively modify wood, cross-linkers and other reactive chemicals or additives must be used. In this work, we have introduced a bio-based cross-linker in a 20% tannin (Quebracho) aqueous solution. Five levels of cross-linker (0, 2, 10, 20 and 40% of total tannin solid) were used to modify Scotspine (Pinus sylvestris L.) sapwood with dimensions of 25 × 25 × 10 mm3 (radial × tangential × longitudinal). Full-cell impregnation was applied with a 60 min vacuum and pressure for 60 min. Samples were kept at room condition for 24 h, stepwise dried to avoid drying defects and cured at 140 °C for 10 h. Modified wood samples are shown in Figure 1. Weight percentage gain (WPG) and bulking coefficient (BC) after water leaching for 5 days were measured according to Donath et al. (2004).

Abstract

Key message This article presents the leaching, fire and weathering resistance improvements of samples treated with tannin-based wood preservatives added of caprolactam. PEG-added formulations show limited applicability. The FT-IR and 13 C-NMR analyses of the caprolactam-added formulations show some evidences of copolymerization. Context Tannin-boron wood preservatives are known for their high resistance against leaching, biological attacks, fire as well as for the good mechanical properties that they impart to wood. These properties promoted these formulations for being a candidate for the protection of green buildings. However, the low elasticity of these polymers and their dark colour implied limited weathering resistances. Aims The aim of the study is to find suitable additives for tannin-based formulations to overcome their limited weathering resistances, without compromising the other properties. Methods Treatment, leaching and fire tests, dimensional stability as well as artificial and natural weathering of the timber treated with caprolactam-added and PEG-added formulations were performed. FT-IR and 13C-NMR of the formulations were presented. Results The presence of caprolactam improved the properties of the formulation with particularly significant results in terms of resistance against leaching and dimensional stability. These enhancements were imparted also to the weathering resistance of the tannin-caprolactam formulations. Indeed, the colour changes during the artificial and natural exposures were stable for longer periods. FT-IR and 13C-NMR investigations of the advanced formulations were led, and covalent copolymerization of the caprolactam with the tannin-hexamine polymer was observed. Conclusion The tannin formulations with caprolactam improved the durability of the wood specimens, while the PEG-tannin presented strong application drawbacks.
