The antioxidant activity of the natural phenolic extracts is limited in particular food systems due to existence compounds glycoside form. Acid hydrolysis post-treatment could be a tool convert glycosidic polyphenols aglycones. Therefore, this research investigated effects an acid on composition and parsley obtained by ultrasound-assisted extraction method delay lipid oxidation real system (i.e., soybean oil-in-water emulsion). conditions were varied maximize total content (TPC) 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. When exposed 0.6 M HCl for 2 h at 80 ℃, TPC was 716.92 ± 24.43 µmol gallic equivalent (GAE)/L, DPPH 66.89 1.63 %. Not only did increase concentrations individual polyphenols, but it also resulted release new phenolics such as myricetin acid. extract's metal chelating ferric-reducing increased significantly after hydrolysis. In emulsion containing 400 GAE/L, acid-hydrolyzed extract had 11-day lag phase headspace hexanal compared 6-day unhydrolyzed extract. findings indicated that conversion aglycones can help extend shelf-life emulsion-based foods.

Cocoa pod husks (CPH) and cocoa bean shells (CBS) are the main by-products of industry a source bioactive compounds. These residues not completely used thrown in fields without any treatment, causing environmental problems. Looking for holistic valorization, aim this work was first to deeply characterize CPH CBS their chemical composition, amino acid, fatty acid profiles, as well application antioxidants. had high level protein (17.98% DM) lipids (16.24% compared with (4.79 0.35% DM respectively). Glutamic aspartic were predominant acids. The total phenolic compounds (TPC) detected ethanolic extracts similar pyrogallol polyphenol (72.57 mg/L). extract showed higher antioxidant activity than CPH. Both increased oxidation stability soybean oil by 48% 32% (CBS). In addition, alkaline pretreatment found suitable release 15.52 ± 0.78 g glucose/L after subsequent saccharification commercial enzyme Cellic®. CTec2.

Thermal Characteristics and Kinetics of the Thermal Degradation of Sugar Beet Waste Leaves and Pulp in Relation to Chemical Composition

Foods, Journal Year: 2025, Volume and Issue: 14(2), P. 307 - 307

Published: Jan. 17, 2025

Thermal characteristics of dried sugar beet pulp, leaves and leaf fractions obtained after extraction: fibrous pulp fibre rich fraction, were investigated by differential scanning calorimetry thermogravimetry. The samples showed a similar thermal behaviour associated with composition. Two endotherms are found on the curves. First one in temperature range 31-153 °C second from 150-160 °C. degradation kinetics was studied thermogravimetric analysis. Four stages observed within 25-700 kinetic parameters degradation, Ortega Friedman non-isothermal isoconversional methods did not significantly differ between models: Ea-activation energy at conversion degree 0.1-0.9 ranged 50-200 kJ/mol; lnA- natural logarithm pre-exponential factor 8-48; kp1-thermal rate constant extent 0.5 0.19-2.55 min-1.

This study investigates the melatonin profile in leaves of Liberica ( Coffea liberica ) and Robusta canephora coffee plants, assessing its potential as a growth indicator during vegetative phase. Our research posits that concentrations vary with leaf age can be effectively detected through Thin Layer Chromatography (TLC) Liquid Chromatography-Mass Spectrometry (LC-MS) analysis. Results showed all samples—young, middle-aged, old—from both species exhibited melatonin, confirming role various physiological processes. LC-MS analysis revealed 0.72% 0.58% young middle-aged leaves, respectively. In contrast, slightly higher levels (0.73%) lower (0.51%). These findings suggest is crucial promoting stress tolerance, particularly leaves. Furthermore, variations between two indicate species-specific adaptations related to photosynthesis environmental resilience. The results underscore pivotal developmental stages plants propose indicator. finding paves way for future refine optimize analytical methods detection sparking further interest exploration this area.
