Pectin is a group of structurally diverse dietary fibers, very abundant in agri-food waste and by-products such as those generated during apple cider manufacturing. In recent years, pectin pectinoligosaccharides have demonstrated good fermentation properties prominent health promoting traits, particularly ameliorating certain inflammatory conditions. previous investigations pomace derived from production monovarietal Asturian ciders was to represent source with varied structural characteristics. this work we investigated vitro the modulatory effect fractions selected on human microbiota healthy subjects bowel disease (IBD) patients through fecal batch fermentations 16S rRNA gene sequencing. Overall, these promoted growth Akkermansia, Lachnospiraceae UCG-010, Prevotella, Sucinivibrio Turicibacter samples donors, while Blautia, CAG-56, Dialister, Eubacterium eligens Intestinimonas were stimulated IBD patients. The E. group, Succinivibrio only occurred tested by-products, not other non-pectic prebiotics/substrates. Galactose content (Arabinose + Galactose)/Rhamnose ratio pomace, galactose rhamnose pectin, positively associated promotion most genera. This comprehensively characterize gut modulation demonstrating capacity distinct fractions. diversifies opportunities achieve valorization formulation novel prebiotics for particular population groups.

Apples and Apple by-Products: Antioxidant Properties and Food Applications

Antioxidants, Год журнала: 2023, Номер 12(7), С. 1456 - 1456

Опубликована: Июль 19, 2023

In recent years, there has been a growing interest in utilizing natural antioxidants as alternatives to synthetic additives food products. Apples and apple by-products have gained attention potential source of due their rich phenolic content. However, the extraction techniques applied for recovery compounds need be chosen carefully. Studies show that ultrasound-assisted is most promising technique. High yields with antioxidant properties obtained by applying ultrasound on both apples by-products. Promising results also reported green technologies such supercritical fluid extraction, especially when co-solvent used. Once extracted, studies indicate feasibility using these products packaging materials. The present review aims provide comprehensive overview by-products, techniques, applications because or nutritional properties. findings here highlight proper utilization reduce detrimental effect environment positive impact economy.

Exploring a Sustainable Process for Polyphenol Extraction from Olive Leaves

Foods, Год журнала: 2024, Номер 13(2), С. 265 - 265

Опубликована: Янв. 15, 2024

Olive leaves are residues from pruning and harvesting considered an environmental management problems. Interestingly, these contain high polyphenol concentrations, which can be used to treat chronic diseases. However, compounds a technological challenge due their thermolability reactivity during extraction. Thus, this study assessed the use of pressurized liquid extraction (PLE) with green solvents like water-ethanol water-glycerol mixtures (0–15%) at 50 °C 70 yield polyphenol-rich antioxidant extracts reduced glucose fructose content. The 30% ethanol 70°C presented highest content (15.29 mg gallic acid equivalent/g dry weight) capacity, was expressed as IC50 (half maximal inhibitory concentration): 5.49 mg/mL oxygen radical absorbance capacity (ORAC): 1259 μmol Trolox weight, well lower sugar (glucose: 3.75 mg/g fructose: 5.68 compared water–glycerol mixtures. exhibits higher degree effectiveness in recovering flavanols, stilbenes secoiridoids, while glycerol improves phenolic acids flavonols. Therefore, enhance efficiency recovery PLE process, it is necessary consider its solvent composition chemical structure.
