Tobacco cultivation is characterized by high amounts of waste biomasses whose disposal frequently represents a complex and expensive problem. A study was conducted to evaluate thepotential of pre-harvest light air-cured (Burley) and dark fire-cured (Kentucky) tobacco waste biomasses as a source of bioactive compounds (nutraceutical ingredients) such as polyphenols. Pre-harvest waste materials (topping fresh materials and residual stalks at final harvest) were collected to determine dry matter, total polyphenols content (TPC; Folin assay), and DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,20-azino-bis(3-ethylbenzothiazoline-60-sulfonic acid) diammonium salt) antioxidant capacity. Polyphenols quali-quantitative profiles obtained by Orbitrap Q Exactive of both tobacco types were also determined. Total pre-harvest waste biomass amounted to 3956.9 and 1304.4 kg d.w. ha−1 in light air-cured (Burley) and dark fire-cured (Kentucky) tobacco types, respectively. Polyphenols content, expressed as g kg−1 dry weight (d.w.), ranged between 4.6 and 15.7 g kg−1 d.w. and was generally greater in leaves than in stalks. Considering both leaves and stalks, the light air-cured (Burley) tobacco crop yielded 22.1 kg ha−1 of polyphenols, while the dark fire-cured (Kentucky) tobacco yielded 12.0 kg ha−1. DPPH and ABTS were significantly greater in leaves than in stalks waste biomass in both types of tobacco. The most abundant components were quinic and chlorogenic acids, rutin, and luteolin rutinoside.

“…The circular economy has two primary goals: improving waste management (or reutilizing), reducing energy consumption (or boosting green energy) (Kapsalis et al, 2019). It is believed that by transforming the agri-sector into circular, apart from the technological sector, circular economy goals could be more achievable; since the agri-sector is one of the most sectors in which a high percentage of biomass has been produced (Jimenez-Lopez et al, 2020). On top of that, renewable biological resources (biomass) and circularity are the critical aspects of the bioeconomy (D'Adamo et al, 2020a); thus, materials recycling, fossil fuel use reduction, and waste management lead the bioeconomy to obtain biofuel, bioenergy, etc., which are vital for achieving sustainable development goals (SDGs) (Duque-Acevedo et al, 2020, Morone & D'Amato, 2019.…”

Measuring efficiency in the presence of undesirable outputs could be difficult depending on how to treat these outputs; thus, undesirable outputs modelling has been an exciting subject of several studies in the Data envelopment analysis (DEA) literature in the last two decades. The present study aims to illustrate a thorough overlook of studies in which DEA has applied for measuring efficiency with undesirable outputs. Fifty-eight articles were published from 2000 to 2020 have been systematically reviewed through PRISMA protocol. The results indicated that "Journal of Cleaner Production" ranked first with six published articles, and Chinese scholars have the most contributions to this field, with twenty-third articles. Also, almost a quarter of the published articles' scope was related to agricultural pollution, and thirteen articles were published in 2016, the highest number of published articles annually. Taken together, the theoretical and empirical implications of research in the field of Green Productivity are discussed, and some policies were recommended.

“…Other similar biologics such as curcumin 37-39 , resveratrol 40 , sulphoraphane 41 and Epigallocatechin-3-Gallate (EGCG) 42 , have also well-established biological associations with the prevention or reduction of the secretion or activation of proinflammatory cytokine cascades 43 . The functional recovery of phenolics from agricultural by-product can obtain products such as SA that can be reinserted into the economy as new raw material 44 . In this regard, biologics, such as SA Extracts I and II could potentially be incorporated into food matrices, for example snacks or drinks, which are easily consumed and more patientfriendly.…”

An In Vitro Study Determining the anti-inflammatory activities of sinapinic acid-containing extracts generated from Irish rapeseed meal

Sinapinic acid (SA) has been shown to possess various bioactive properties including anti-diabetic, anti-inflammatory and histone deacetylase inhibitory activities. However, the amount obtained from our diet is insufficient to produce beneficial effects on health. Therefore, isolating this bioactive phenolic from a natural source, such as rapeseed meal, could generate extracts containing concentrated amounts of SA which could be consumed as a functional food ingredient to prevent health-related disease, particularly inflammation. Inflammation is a multi-faceted pathology, which plays a role in numerous diseases including cardiovascular disease, diabetes, arthritis and cancer. Current therapies such as non-steroidal anti-inflammatories (NSAIDs) are associated with various adverse side effects, with the result being an increase in research aiming to identify natural compounds which possess anti-inflammatory activity. In this work, an in vitro study assessed the anti-inflammatory activities of two sinapinic acid-containing extracts on human-derived peripheral blood mononuclear cells (PBMCs). Both extracts were found to significantly reduce the levels of key pro-inflammatory cytokines including TNF-alpha, IL-12 and IL-6. Importantly, these extracts were found to be more potent than commercial SA in terms of their anti-inflammatory activities. Results demonstrate the potential of these extracts as anti-inflammatory agents.

Agriculture waste valorisation as a source of antioxidant phenolic compounds within a circular and sustainable bioeconomy

Abstract: Agro-food industrial waste is currently being accumulated, pushing scientists to find recovery strategies to obtain bioactive compounds within a circular bioeconomy. Target phenolic compounds have shown market potential by means of optimization extraction techniques.
