The yield and functional properties of durian seed gum (DSG) are highly dependent on the extraction process. Aqueous-extracted DSG from dry seed at high temperature and alkaline condition (dry seed method) showed the highest yield (31.06 %) and the most desired shear-thinning behaviours, gelling and sorption properties for eutectogel formulation in food coating application. Choline chloride-fructose (1:2) natural deep eutectic solvent (NADES) was used to extract the phenolic compounds from oil palm leaves (OPL) due to its higher efficiency and stability in eutectogel formulation. The optimal extraction temperature, time and solid-to-liquid ratio were found at 40 °C, 20 min and 0.02 g/mL, respectively, to achieve maximum total phenolic content (TPC) yield of 28.22 mg/g OPL. The high viscosity eutectogel protected nutrients from oxidation and demonstrated excellent stabilization ability over 40 days of storage. The degradation rate of gallic acid in NADES and DSG were almost 2-fold and 10-fold higher than eutectogel, respectively. This study shed light on the potential of fortified eutectogel containing oil palm leaf extract (OPLE) as a novel coating material in food preservation. The extraction processes of DSG and OPLE, as well as the formulation of NADES and eutectogel are tunable for desired properties and application.

Membrane-based separation technologies like ultrafiltration (UF) and microfiltration (MF) are widely used for concentrating and separating proteins and other milk components. Despite significant advancements, fouling remains a major challenge, increasing operational costs, processing time, and energy consumption. This review thoroughly examines fouling characterisation in milk UF and MF processes, focusing on the interplay between membrane properties, operating conditions and solution properties. The review highlights the critical need for effective fouling mitigation strategies. It provides an in-depth analysis of fouling properties, factors influencing filtration, and advanced techniques for characterisation. The discussion also addresses the optimisation of cleaning procedures, emphasising the importance of understanding the chemical and morphological characteristics of fouling to develop tailored cleaning protocols. Such customised approaches can result in reduced standard cleaning sequences, leading to the conservation of water and chemicals. The review suggests future research directions, emphasising the importance of collaboration between dairy processors and cleaning agent suppliers to enhance cleaning strategies. It highlights the necessity of employing multiple analytical techniques to comprehensively understand fouling, linking it with filtration performance data from real processes.

The carbon footprint (CF) analysis of meat production and processing at a large industrial plant in Poland was carried out. In the face of growing environmental awareness and sustainability reporting requirements, the meat industry's impact on greenhouse gas (GHG) emissions was examined. The analysis focused on the slaughtering and processing processes of animal raw materials, taking into account direct and indirect emissions (electricity, fuel, transportation and refrigerant consumption). The collected data made it possible to develop a uniform methodology for calculating CF, covering the full life cycle of meat products in a plant. A measurement system and database were created to collect key information on emissions. The total CF of pork production was 0.497 kg CO_2eq/kg. The results showed where the highest emissions are generated, allowing the identification of areas with the highest CF and opportunities for reduction. Average production-related GHG emissions came mainly from indirect emissions (electricity consumption) and accounted 68 % and 70 % respectively for slaughterhouses and processing plants The study highlights the importance of uniform standards for analyzing the meat industry's CF and their impact on the movement toward sustainable production, which is crucial in the fight against climate change. The developed results allow for conscious management of the company's sustainable development.

Although deeply studied, the list of 3D Food Printing (3DFP) compatible materials is still short compared to traditional food manufacturing methods. This study focused on the printability of chickpea flour enriched with omega-3-rich oil and the effect of extrusion processing on printability. The functional and nutritional advantages of extrusion processing generated novel materials for 3D food printing. Four flours were used: NE (non-extruded), NEO (oil enriched), E (extruded), and EO (oil enriched). The water content varied across 14 formulations (34–36–40 % for NE and NEO and 66–68–70–72 % for E and EO), all printed at two temperatures (T1–25 ºC and T2–35 ºC). The prints’ dimensional accuracy was assessed to find the best formulation for each flour type. Following the least percentage error in each material´s top-view printability, the four best formulations were rheologically characterized (amplitude sweep, shear-viscosity, time-viscosity, temperature-viscosity, and recovery). Based on printability, the best formulations were NE-36-T1 (non-extruded sample with 36 % water content printed at 25 ºC) and E-72-T1 (extruded sample with 72 % water content printed at 25 ºC), yielding the lowest printing deviations (29.03 and 30.07). Omega-3 enrichment significantly decreased the yield stress (3262 Pa for NE-36 to 2831 Pa for NEO-36, and 3304 Pa for E-72 to 1766 Pa for EO-72). All formulations remained viscoelastic, with EO-72 having the lowest recovery percentage. These results showed the compatibility of extruded and non-extruded chickpea flour with 3DFP, granting their further integration as ingredients in more complex formulations.

New data on the solubility (buffers pH 2.0, pH 5.0, pH 7.4, EtOH (ethanol), OctOH (1-octanol) and IPM (isopropyl myristate)), distribution (OctOH/buffer and IPM/buffer systems), and permeability through the polydimethylsiloxane-polycarbonate membrane (PDS) and PermeaPad barrier (PP) of three structurally similar nitrofuran class drugs: nifurtimox (NFM), nifuratel (NFT) and nifuroxazide (NFX) have been obtained. All the compounds appeared to be very sparingly soluble in the range of physiological pH. In addition, low solubility in organic solvents: EtOH > OctOH > IPM was also determined. The solubility of the studied substances in the organic solvents was shown to be higher than in the aqueous media. The values of the distribution coefficients appeared to be in agreement with the solubility in the respective solvents. According to the distribution in the OctOH/buffer system, only NFX matched the range of optimal lipophilicity (logD=1÷3) for successful absorption. Permeability of all the studied nitrofuran derivatives was shown to be essentially greater through the PP barrier as compared to the PDS membrane. The trends between the distribution coefficients and permeability were disclosed.

French fries are widely consumed globally; however, their high oil content and the presence of lipophilic pollutants, such as polycyclic aromatic hydrocarbons (PAHs), which are linked to carcinogenic and mutagenic effects, pose significant health concerns. This study investigated the effects of three pre-drying methods- hot air drying (HAD), vacuum drying (VD), and microwave drying (MD) on PAH4 migration and key quality parameters of French fries, including oil content, hardness, and microstructural changes. The stable isotope-labeled PAH4 (PAH4-d12) were employed to simulate the migration of PAH4 from frying oil to French fries. SEM and CLSM 3D imaging revealed that HAD and VD had a denser microstructure in the fries, reducing oil absorption and PAH4 migration, while MD caused structural damage, increasing porosity and PAH4 migration. The results demonstrated that HAD and VD significantly minimized PAH4 migration, resulting in a firmer French fry with reduced oil absorption and improved oil retention. Specifically, these methods significantly reduced the oil content in French fries by 16.00–37.54 % and increased their hardness by 37.10–91.05 %. In contrast, MD increased PAH4 migration due to structural degradation, including the formation of larger pores, which facilitated significantly higher oil absorption. This study demonstrates that pre-drying methods such as HAD and VD can effectively reduce PAH4 exposure, enhance food safety, and improve the textural properties of French fries, offering a practical approach for producing healthier fried products.

Lactiplantibacillus plantarum (L. plantarum) has promising applications in the development of probiotics, largely based on its recently recognized role in the gut–heart–brain axis. However, its survival rate after freeze-drying and its storage stability are key factors limiting the development and application of L. plantarum. In this study, we mixed skimmed milk, trehalose, and inulin (SMTI) in a 1:8 mass ratio with L. plantarum W1, followed by freeze-drying. The results showed that using SMTI as a protectant could increase the freeze-dried survival rate to 86.87%+0.9%. After 1 month, the viability of the freeze-dried bacterial cells was 2.87+0.44×10⁹ CFU/g. By measuring relevant enzyme activities, we found that the addition of this protectant enhanced the activity of Na⁺-K⁺-ATPase, Ca²⁺-Mg²⁺-ATPase, and total ATPase during freeze-drying. These enzyme activities maintained the integrity of the L. plantarum W1 cell membrane and reduced the leakage of lactate dehydrogenase and β-galactosidase. Therefore, SMTI improved the freeze-dried survival rate of L. plantarum W1 and increased its resistance to adverse conditions. Our study provides a new formula for a probiotic protectant, offering a new method by which to preserve probiotic strains during freeze-drying.

The standardized plant extract rich in anthocyanins (approximately 15,000 ppm) extracted from E. edulis fruits (AnthocyanOx®) has demonstrated potential uses and applications for the development of new products in food, cosmetic, and pharmaceutical industries. Anthocyanins provide several health benefits, showing potential to prevent damage and diseases caused by oxidative stress, protein glycation, and premature aging. New formulations enhancing benefits of standardized extract have been developed and green synthesis of metallic nanoparticles have attracted great interest. Techniques such as UV-Visible spectroscopy, Dynamic Light Scattering (DLS), and Scanning Electron Microscopy (SEM) were conducted to characterize silver nanoparticles (AgNPs) synthesized using AnthocyanOx® aqueous extract (EeAE). Antioxidant activity was assessed through DPPH radical scavenging, Ferric Reducing Antioxidant Power (FRAP), ABTS radical scavenging, and Oxygen Radical Absorbance Capacity (ORAC). Molecular docking analyses were conducted to evaluate molecular interactions. The characterization demonstrated AgNPs formation. Antioxidant evaluations showed high antioxidant activity for both EeAE and AgNPs. In silico assays demonstrated that anthocyanins interacted with all enzymes evaluated. These results represent an important indicator for the development and discovery of new nanostructured formulations using standardized extracts rich in anthocyanins extracted from E. edulis for food, cosmetic, and pharmaceutical industries.

Chinese-liquor distillers grains (CDG) is an industrial organic waste due to its abundant unfermented polymeric sugars. In this study, CDG was used as the sole carbon and nitrogen source for polymalic acid (PMA) fermentation by Aureobasidium pullulans. The saccharification of CDG was conducted using 5 % (v/v) H₂SO₄ with a high solid-liquid ratio of 0.3, followed by resin-detoxification and cellulase hydrolysis. Glucose and xylose were obtained in CDG hydrolysate with a sugar recovery of 39.3 % and 51.3 %, respectively. A. pullulans utilized glucose and xylose simultaneously, but carbon catabolite repression was still observed. The co-fermentation of glucose and xylose yielded enhanced cell growth and sugar consumption, whereas sole-glucose fermentation resulted in higher PMA titer. After optimization, 38.6 ± 1.7 g/L of PMA was produced from CDG hydrolysate with a yield of 0.35 g/g sugar. This study provided an important biorefinery strategy for PMA production from CDG feedstock.

Assessing the costs, benefits, and externalities of circular economy measures from a life cycle perspective is increasingly important for developing sustainable agro-food strategies. This study evaluates the carbon and water implications of revalorising glucosinolates from broccoli by-products through two distinct life-cycle scenarios in a case study conducted in Navarra, Spain. In the first scenario, glucosinolates are obtained from conventional broccoli production, where they are naturally present in the edible inflorescences. The second scenario introduces an innovative step: extracting glucosinolates from otherwise discarded broccoli by-products, such as stalks and inflorescence detachments. Carbon and water footprints were analysed for both scenarios based on the production of 1000 grams of glucosinolates. The results reveal that while the second scenario enhances resource efficiency by utilizing agricultural waste, the environmental costs of the extraction process outweigh the benefits, leading to a 37.6 % increase in greenhouse gas emissions and a 4.6 % rise in water usage compared to the first scenario. To address this, an improvement scenario is proposed, featuring a more efficient use of solvents during extraction, which significantly reduces both emissions and water use. This study underscores that circular economy strategies in agro-food systems do not always translate into environmental benefits accross all resources. A detailed analysis of various carbon and water indicators has provided valuable insights to enhance the environmental performance of such strategies, reinforcing the importance of life-cycle assessments in shaping more effective agro-food policies.
