Biomass is the only renewable hydrocarbon resource on Earth and therefore plays an essential role in a future sustainable society. Nevertheless, biomass underutilized for production of chemicals, instead burned energy or left compost. Derived from biogenic carbohydrates, gamma-valerolactone (GVL) holds pivotal potential as green fuel, solvent, platform compound. Converting carbohydrate-rich waste directly to GVL highly attractive but also very challenging owing inert nature high complexity biomass, necessitating versatile selective catalytic system. Developing benign complexity-preserving valorization processes would not allow methods synthesize valuable commodity provide access carbon-negative procedures. Therefore, producing GVL, that preserves five out six C–C bonds hexoses all pentoses, has potential. We describe first direct conversion raw lignocellulose, starch, chitin GVL. Using 1.8 wt% homogeneous catalyst Ru-MACHO-BH 10.9 M H3PO4(aq) with 30 bar H2 at 140 °C 24-120 hours provides excellent yields (10-26 wt%) twelve different industrially processed biowaste sources, either individual substrates combined pool. This corresponds 26-48mol% yields, average approximately 80-90 mol% yield each reaction step.

This study provides a comprehensive analysis of the composition onion peels, tomato and pistachio green hulls, with focus on their structural bioactive compounds. Onion regardless cultivar, were found to be rich in quercetin its derivatives, along other flavonoids pectin. Tomato peels emerged as notable source naringenin (0.52 mg/g ethanol extract) rutin (0.24 water showed an unexpectedly high lignin content, comprising nearly 50% components. Pistachio hulls demonstrated extractive content (63.4 g/100 g), 73% which water-soluble. Protocatechuic acid, rutin, derivatives dominant phenolic compounds extract, while luteolin was most abundant extract. Regarding composition, shared similarities, exhibiting (53.4% 33.8%, respectively) uronic acids (10–15%). In contrast, characterized by levels glucans (around 38%) galacturonic acid (33%). The insights from this pave way for design sustainable efficient extraction processes, enabling sequential recovery valuable promoting valorization these agro-industrial by-products. Additionally, evaluated sources pectin using two methods: conventional subcritical extraction. results revealed significant differences (53–68% acid) degree esterification (79–92%) compared commercial (72.8% 68% esterification), highlighting influence raw material method final properties

Abstract Food waste poses significant environmental, economic, and social challenges worldwide. Pistachio is recognized for its health benefits, particularly anticancer properties. This study assessed the phytochemical characteristics of pistachio hull (PH) shell (PS) using various solvents (ethyl acetate, hexane, methanol). Methanolic extracts showed substantially higher phenolic flavonoid contents along with enhanced antioxidant activity across all tested methods, PH consistently outperforming PS in Cell viability tests on MCF-7 cancer cells indicated that PH-Hexane had a slightly greater effect than PH-ethyl acetate PH-methanol. cycle analysis revealed notable arrest G0/G1 phase compared to control group. Additionally, treatment resulted 21.24% apoptosis, primarily early apoptosis at 19.41%. The pathway involving 46 genes induces by modulating several metabolic pathways, those associated immune system, developmental biology, signal transduction, cellular responses stimuli. induction was characterized substantial upregulation CEBPB, HIF1A, MYC downregulation ATF2, CEBPA, NR3C1 genes. findings this indicate hexane extract derived from high-oil-content wastes has potential as an agent. Future research oil-rich plant-based should consider utilizing solvent further exploration

Pistacia vera L. shells (PS) are a sustainable source of health-promoting ingredients. The metabolic fate PS extract with antioxidant/antiradical and hypoglycemic properties prepared by microwave-assisted extraction (MAE) was investigated through in vitro gastrointestinal digestion to consider its potential value as nutraceutical ingredient. results revealed significant changes the phytochemical profile, bioactivity, bioaccessibility during digestion. According LC-ESI-LTQ-Orbitrap-MS analysis, compounds were mainly preserved oral (40.48 μg/mg DW) gastric (73.67 phases, less intestinal phase (13.24 DW). α-Amylase inhibitory remained consistent digestion, whereas α-glucosidase inhibition effects gradually decreased. Multivariate data analysis confirmed interdependency between composition bioactivity undigested digests. This study represents step forward for developing PS-based functional foods, providing unique insights into metabolism bioactive constituents under simulated conditions.

In Argentina and globally, pistachio (Pistacia vera) production has significantly grown, driven by its high nutritional value food industry demand. Its harvesting processing generate about 40% of waste (PW), including leaves, twigs, seed coats, green, empty kernels. Underutilized PW led to environmental problems, soil water contamination landfill accumulation. However, it could be a potential source undiscovered bioactive compounds. This study aimed characterize the chemical profile evaluate properties PW. The dried (dPW) was used prepare decoction (PWD) (10% w/v). total phenolic content (TPC) flavonoid (FC) were quantified, analyzed using UPLC-DAD-ESI-MS/MS. Nematicidal activity against Meloidogyne incognita (J2), acetylcholinesterase (AChE) butyrylcholinesterase (BuChE) inhibition, antioxidant capacity (ABTS, DPPH, FRAP), phytotoxicity on Allium cepa, Lactuca sativa, Raphanus sativus evaluated. UPLC-DAD-ESI-MS/MS analysis identified 26 compounds, phenolics, flavonoids, unsaturated fatty acids. main compounds gallic acid, anacardic quercetin derivatives. TPC FC 212.65 mg GAE/g dPW 0.022 QE/g dPW, respectively, displaying strong across assays ABTS, FRAP. PWD exhibited nematicidal M. (J2) (LC50 = 0.12% at 24 h). Alterations in cuticle observed, structural disorganization detachment from internal tissues. Additionally, remarkable cholinesterase inhibitory effect detected 2.0% (42.65% for AChE 58.90% BuChE). showed low phytotoxic effects tested species, germination percentage (GP) mean time (MGT) not affected (GP > 79%). These findings highlight as sustainable alternative control, nematicidal, anticholinesterase, properties, phytotoxicity, supporting use agricultural practices.
