Pomegranate peel waste is a byproduct of juice processing and 1.6 million tons are produced globally each year. Pomegranate peels have a high dietary fiber content and unique polyphenol profile suggesting it may have health benefits. This study aimed to investigate the hypocholesterolemic and anti-obesity effects of pomegranate peel powder (PPP) and water extract (PPE) in Golden Syrian hamsters fed with high-fat (39 % fat calorie, HF) diets. Hamsters were fed either the HF, or the HF diet supplemented with 2.5 % or 5 % PPE (LE and HE, respectively), or 5 % or 10 % PPP (low-peel (LP) and high-peel (HP), respectively. After 4 weeks of feeding, hamsters gained 16.10- 33.82 g of weight and the feeding efficacy ranged from 0.10 to 0.18. The HP group had the lowest weight gain and feed efficacy while others were not significantly different. The HP group had significantly lower liver-to-body weight ratio (3.10 ± 0.08 % vs 3.65 ± 0.09 %), fasting blood glucose (68.11 ± 5.27 vs 82.94 ± 6.49 mg/dL), and hepatic lipid content (6.31 ± 0.26 vs 7.49 ± 0.22 g/100 g liver) compared to the HF group. PPP ingestion significantly increased LDL but decreased triglycerides. PPP and PPE feeding resulted in microbiota phyla Firmicutes-to-Bacteroidetes ratio characteristic of leaner phenotypes. HMG-CoAR and LDLR expression were reduced, suggesting that decreased uptake of LDL was not sufficient to lower plasma LDL, even with reduced cholesterol synthesis.

This study evaluates the effects of pH levels and Zein/Gum Arabic (Z/GA) ratios on key encapsulation parameters of an anthocyanin-rich extract (ARE) derived from purple corn cob, using the antisolvent precipitation method. Parameters analyzed include encapsulation efficiencies for anthocyanins (%AEE) and polyphenols (%PEE), nanoparticle size, polydispersity index, ζ-potential, and thermal stability at 80 and 180 °C. Particles without GA showed poor stability and low %AEE, particularly at lower pH. Conversely, the addition of GA significantly enhanced encapsulation efficiency, especially under acidic conditions (pH 2–4), and improved the particle size uniformity. At Z/GA ratio of 1:1, GA played a crucial role in stabilizing nanoparticles, effectively preventing aggregation even when the net particle charge was near to zero. Characterization by SEM, FTIR and TGA confirmed the morphological, structural, and thermal properties of the encapsulated particles. Thermal stability tests demonstrated that encapsulated anthocyanins exhibited significantly improved resistance to thermal degradation, with half-life extended up to threefold compared to unencapsulated counterparts. These results highlight the potential of encapsulating ARE from purple corn cob in Z/GA matrices as a method to preserve anthocyanins functionality, improve their thermal stability during food processing, and enhance application in food systems. Additionally, this approach offers a sustainable alternative, adding value to agricultural by-products and promoting waste valorization in the food industry. However, further research on scalability, cost-effectiveness, and application in food processing systems are needed.

This study aimed to develop a novel, degradable antimicrobial bioactive coating by combining Ferula haussknechtii gum and polyethylene oxide with lemongrass essential oil (LGEO) using the emulsion electrospinning technique. The LGEO emulsion in the F. haussknechtii gum/polyethylene oxide solution was prepared via ultrasonic method, and its physicochemical properties, including pH, electrical conductivity, density, and apparent viscosity, were systematically evaluated. The microstructural morphology of the electrospun coating was analyzed using scanning electron microscopy (SEM). The antimicrobial properties and antioxidant potential of the active electrospun coating were also assessed. The resulting electrospun fibers had an average diameter of 0.56 μm and contained over 36 bioactive compounds, exhibiting radical scavenging activity of approximately 74.51 %. The LGEO was incorporated into the bioactive coating at concentrations of 3, 6, and 9 % (v/v). The antimicrobial efficacy of the electrospun coating was tested against Gram-positive Gram-negative, and Aspergillus niger. The highest antimicrobial activity was observed with the electrospun coating containing 9 % LGEO. The results revealed that increasing the LGEO concentration in the emulsion resulted in decreased pH, apparent viscosity, and density, while electrical conductivity increased. SEM analysis confirmed the formation of uniform, bead-free electrospun fibers across all LGEO concentrations. FTIR analysis validated the successful incorporation of emulsified LGEO into the electrospun fibers. These findings demonstrate that the inclusion of LGEO in bioactive edible coatings can significantly enhance antimicrobial protection, particularly for minimally processed foods, while potentially extending shelf life by reducing microbial contamination.

Thickened fluids, or dysphagic drinks, are commonly prescribed for individuals with swallowing difficulties. They help slow down food bolus in the swallowing process, reducing the risk of choking and aspiration. The main goal of this study was to create a set of high-protein supplement drinks varying in caloric density level. Besides, the study aimed to examine both shear and extensional rheological properties along with visual cohesiveness. Soy protein-based formulations A to F were developed with caloric densities: 1, 1.2, 1.5, 2, 2.5, and 3 kcal/mL, respectively. Each formulation was assessed through the International Dysphagia Diet Standardisation Initiative (IDDSI) flow test, shear and extensional rheological behavior, and visual cohesiveness. All samples exhibited shear-thinning behavior with viscosity increased with higher caloric density. Formulations A and B were classified as low-viscosity liquids, while formulations C, D, E, and F were suitable for extensional flow measurements with extensional properties improving as density increased. Visual cohesiveness, assessed through elongation shape and flow behavior, enhances with formulation concentration. Formulations A and B may require the addition of thickening agents to serve as thickened nutritional supplements for dysphagia management. Formulations C, D, and E were mildly to moderately thick, whereas formulation F, characterized by extremely thick with very high yield stress, may cause multiple swallows. These findings highlight the potential for developing higher-calorie supplements without thickeners as a practical strategy to enhance energy and protein intake in individuals with dysphagia. To ensure safe swallowing, future research should validate these results using in-vitro throat models and clinical studies.

In this study, we analyzed the absorption of linear and cyclic dipeptides containing Gly, Pro, Ala, and Val by human blood following the ingestion of elastin hydrolysate. As in previous studies, Pro-Gly was transferred into blood at the highest concentration (Cmax; 14.63 nmol/mL). Moreover, this is the first study to show that Gly-Pro, Pro-Ala, Gly-Ala, cyclo(Gly-Pro), cyclo(Pro-Ala), cyclo(Pro-Val) and cyclo(Gly-Ala) also increase in blood after the ingestion of elastin hydrolysate. The contents of these cyclic dipeptides, which amounts in elastin hydrolysate is verry small, suggested that elastin digestives may be cyclized during digestion and absorption by human blood following the ingestion of elastin hydrolysate. This study suggested that these blood-transferrable linear and cyclic dipeptides could be candidates for elastin-derived bioactive peptides, and this finding consequently led to the further experiments that has been required for clarifying the bioactivities and mechanisms of beneficial effects of elastin hydrolysate.

Phyllantus amarus and P. muellerianus are herbs reported to possess anti-inflammatory activity. Antinociceptive and anti-inflammatory activities of alginate-based microsphere loaded with extracts of P. amarus and P. muellerianus was here reported. The extract-loaded microspheres were prepared using the ionotropic gelation method. The particle size, swelling index, entrapment efficiency, and FTIR spectroscopy were determined. Antinociceptive and anti-inflammatory activities of extract-loaded microspheres were evaluated in hotplate-induced nociception in mice and carrageenan-induced rat paw oedema, respectively. The physicohemical results showed rigid, free-flowing and spherical microspheres, with particle sizes ranging from 985.977±13.65 to 1232±12.99 µm and entrapment efficiencies of 20.9 ± 0.341 to 45.0 ± 0.002 %. Polymer-drug interaction revealed bands indicating aromatics, alcohols and alkenes. The extract-loaded microspheres showed improved antinociceptive and anti-inflammatory activities when compared to the extracts alone. The sodium alginate-based microspheres loaded with Phyllanthus amarus and Phyllanthus muellerianus extracts showed acceptable physicochemical properties and had improved antinociceptive and anti-inflammatory activity compared to the extracts alone.

Quinoa (Chenopodium quinoa Willd) has gained popularity as a plant-based protein source due to its high protein content and complete amino acid profile. However, protein extraction methods such as alkaline solubilization coupled to isoelectric precipitation (ASIP), can affect protein structure, digestibility, nutritional quality, and the composition of antinutritional factors. This study aimed to assess the effects of ASIP on the secondary structure, protein quality and antinutritional factors (ANFs) composition from three quinoa varieties. The results showed that quinoa protein isolates exhibited a decrease in random coil structures, while β-turns and β-sheets increased, as indicated by FTIR analysis. In vitro protein digestibility improved after protein extraction, ranging from 82.12% to 84.50%. The amino acid score ranged from 0.67 – 0.88, with Yellow quinoa protein concentrate exhibiting the highest value. Black quinoa protein isolate showed the lowest total oxalate content (105.00 mg/100g), while Red quinoa protein concentrate presented higher levels of phytic acid (2.0 g/100 g), saponins (150.0 mg/g), and total phenolic compounds (161.5 mg GAE/100g). Notably, gluten content decreased in all samples following protein extraction. Despite the presence of certain ANFs in quinoa protein isolates/concentrates, the protein quality of quinoa isolates and concentrates was not adversely affected. In conclusion, the extraction process reduced several ANFs, including lectins, oxalates, and gluten, while enhancing the overall protein quality.

Vortioxetine (VTX) is a new atypical antidepressant used to treat major depression and other mental disorders. Due to its low water solubility, oral absorption, and fast metabolism, VTX has been commercially manufactured and sold as a hydrobromide. Long-term VTX hydrobromide therapy is frequently associated with respiratory irritation and digestive dysfunction. Two techniques were developed for dissolution, swelling, adherence, and penetration enhancements. The techniques were the VTX and casein (CAS) complexation using the maximum loading capacity, and VTX-polymeric nano micelle using the “Sandwich Technique”. This study includes the maximum VTX-CAS binding capacity determination, VTX-CAS complex preparation, polymeric nano micelle encapsulating VTX-CAS complex optimizations, physiochemical characterisations, solubility assessment, VTX release analysis, swelling analysis and mucus-penetrating study of the VTX-CAS complex and VTX polymeric nano micelle in comparison to the VTX raw material. The optimum VTX-polymeric nano micelle dissolution, swelling, adherence, and penetration enhancements were supported by the results of 91.10±16.34 nm, +19 mV zeta-potential, structural arrangements, and enhanced amorphic character with the morphology and size distribution (50–100 nm). The VTX-polymeric nano micelle could serve as an oral alternative to the VTX hydrobromide therapy based on the results of the biocompatibility and in vivo absorption studies for the VTX-polymeric nano micellar system.

This study includes the maximum VTX-CAS binding capacity determination, VTX-CAS complex preparation, polymeric nano micelle encapsulating VTX-CAS complex optimizations, physiochemical characterisations, solubility assessment, VTX release analysis, swelling analysis and mucus-penetrating study of the VTX-CAS complex and VTX polymeric nano micelle in comparison to the VTX raw material. The optimum VTX-polymeric nano micelle dissolution, swelling, adherence, and penetration enhancements were supported by the results of 91.10±16.34 nm, +19 mV zeta-potential, structural arrangements, and enhanced amorphic character with the morphology and size distribution (50–100 nm). The VTX-polymeric nano micelle could serve as an oral alternative to the VTX hydrobromide therapy based on the results of the biocompatibility and <em>in vivo</em> absorption studies for the VTX-polymeric nano micellar system.</div></div>","PeriodicalId":12385,"journal":{"name":"Food Hydrocolloids for Health","volume":"6 ","pages":"Article 100189"},"PeriodicalIF":4.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the nutraceutical properties of ethanolic extract of Hyeronima macrocarpa fruits, immobilized on nanocellulose-based aerogels (NCAG) synthesized from the seeds were studied. Specifically, bioactives with antioxidant properties of the pulp were determined, NCAG and homologs of acetate (NCAG-A) and sulfate (NCAG-S) were obtained, and characterized from the seed, the aerogels loaded with antioxidants were studied to determine the anti-radical activity, digestion patterns, protein oxidation inhibition, and toxicological properties. The berries presented a high anthocyanin content of 1317.4 mg C3G/100 g FW and ORAC value of 12,732 µmol Trolox/100 g FW, which make an important source of antioxidants. The seeds presented cellulose content of 61.4 % with a NC yield of 38.4 %. NCAG and their surface homologs were successfully synthesized and characterized by FTIR, DLS, and TEM finding the characteristic bands of the main functional groups, NC presented particle sizes ranging from 64 to 141 nm, BET analysis showed surface areas of 71.1, 102.3, and 183.5 m2/g for NCAG-A, NCAG, and NCAG-S, respectively, and pore sizes of 36–38 nm called mesopores. NCAG presented the highest capacity to trap reactive oxygen species (106.8 mg catechin Eq./g., 86.5 % OH• trapped, respectively). All samples showed the capacity to delay the oxidation of a protein system in a dose-dependent manner, with IC50 values of 70 mg/L (NCAG), 176.3 mg/L (NCAG-A), and 255.6 mg/L (NCAG-S). In vitro digestion showed that NCAG-S was more efficient in delivering anthocyanins under gastric conditions (bioaccessibility of 59.3 %), and NCAG under duodenal conditions (bioaccessibility of 88.2 %). The differences found in samples for the different functional assays can be explained by the various types of interactions generated between the antioxidant molecules and aerogels, in the various media where the analyses are carried out. The results indicate nanocellulose-based aerogels, synthesized from lignocellulosic residues of H. macrocarpa seeds, proved to be porous matrices capable of carrying bioactive substances, and presented interesting properties for the delivery and conservation of antioxidant molecules such as anthocyanins and other polyphenols, achieving an in vitro protective effect against the oxidation of biomolecules.

This study aimed to assess the behaviour of phenolic compounds from yarrow extract encapsulated in nanoemulsions during in vitro gastrointestinal digestion. Oil-in-water nanoemulsions were developed using grape seed oil and lupin protein (LPI) as oil phase and emulsifier, respectively. The use of 6 % LPI including 1 mg/mL of yarrow extract resulted in nanoemulsions with a homogeneous particle size distribution (200 nm) and an encapsulation efficiency of 85.6 %. During in vitro gastrointestinal digestion, most of the phenolics remained encapsulated, being protected from degradation. The in vitro bioavailability of the encapsulated phenolics was measured using a cell co-culture model (Caco-2/HT-29MTX). In this regard, nanoemulsions did not increase the bioavailability of yarrow phenolics, instead, they promoted their access to the colon. Finally, the antiproliferative activity was determined in Caco-2 cells, observing that the apical fraction inhibited cancer cells, indicating the bioefficacy of the non-absorbed phenolics. Thus, this study underscores the potential of LPI-stabilized nanoemulsions as a vehicle for protecting and delivering yarrow phenolics to the colon.
