Pectin is one of high-value functional food ingredients. Better knowledge of properties of chayote pectin would help to promote the application of the chayote as a pectin source. In this study, ultrasound-assisted extraction (UAE) was used to extract chayote pectin. The extraction parameters were optimized by a Box-Behnken response surface design. The highest yield (6.19%) was obtained at a liquid/solid ratio of 50 mL/g, ultrasonic temperature of 70°C and ultrasonic time of 40 min as optimized extraction conditions. The chem. properties, spectral information and rheol. properties of pectin extracted with UAE under the optimum conditions (PEUO) were measured and the results indicated that the PEUO exhibited a low degree of esterification, high molar mass (2.47 × 106 g/mol) and suitable foaming capacity. The PEUO featured a stronger antioxidant capacity compared to com. apple pectin and the PEUO solutions (1%, 2%, 3% and 5%) showed a non-Newtonian behavior. Hence, PEUO may provide beneficial characteristics to find use in food industry.

Camellia Oleifera Shell (COS) is a kind of renewable lignocellulose resource and contains abundant hemicelluloses. In this work, the hemicelluloses in COS were extracted by alkali treatment and precipitated by ethanol with different concentration Thermal pyrolysis kinetics of COS hemicelluloses were investigated using a thermogravimetric analyzer at the heating rates of 5, 10, and 20 °C/min based on Coats-Redfern, Flynn-Wall-Ozawa (FWO), and Kissinger-Akahira-Sunose (KAS) model. The results showed that the best fitting thermal pyrolysis mechanism of COS hemicelluloses was one-dimensional diffusion reaction analyzed by Coats-Redfern model. The activation energies of COS hemicelluloses ranged from 175.07 to 247.87 kJ·mol-1 and from 174.74 to 252.50 kJ·mol-1 calculated by FWO and KAS, resp. The thermal stabilities of COS hemicelluloses were enhanced with the precipitated ethanol concentration increasing, and reflected by thermodn. parameters ΔH, ΔG and ΔS. This study may provide basic theor. supports for the thermochem. conversion of COS hemicelluloses.

Polysaccharides were extracted from Schizophyllum commune (a common mushroom) and their structural and immune-enhancing properties were investigated. Crude and fractions (F1 and F2) were composed of sugars (50.3-82.8%), proteins (1.46-20.1%), and sulfates (1.33-7.01%). Monosaccharide compositions of Cr and F1 were mainly composed of glucose (75.5% and 88.2%) with small amounts of mannose, galactose and xylose whereas the F2 was mainly composed of manose (55.2%) with minor amounts of galactose, glucose, and xylose. Their immune-enhancing activities were tested using RAW264.7 cells. Proliferation activity of RAW264.7 cells was over 100% after treatment with these polysaccharides. In addition, RAW264.7 cells produced large amounts of nitric oxide and various cytokines by up-regulating mRNA expression levels and the activation of nuclear factor-kappa (NF-κB) and mitogen-activated protein kinase (MAPK) after treatment with these polysaccharides. In addition, RAW264.7 cells were activated mainly through CR-3 and TLR-4 receptors. The backbone of F2 with excellent immune-enhancing activity was mainly linked by (1→3)-linked-mannopyranosyl and (1→2,3)-linked-mannopyranosyl residues.

Meng, Xin published the artcileStructural characterization and immunomodulating activities of polysaccharides from a newly collected wild Morchella sextelata, Name: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is polysaccharide Morchella sextelata immunomodulator macrophage; Immunomodulatory; Morchella sextelata; Polysaccharides; Purification.

A purified polysaccharide was acquired from a newly collected wild Morchella. The strain identification initially showed that the strain was Morchella sextelata. This study aimed to investigate the structural features and immunomodulating activities of the polysaccharide. Polysaccharide extracted from mycelia was purified by DEAE-cellulose chromatog. and Sephadex G-25 size-exclusion chromatog. in sequence. The main fraction of polysaccharide (MSP-II) was obtained during purification process. High Performance Liquid Chromatog. (HPLC) anal. revealed that MSP-II was composed of Glc, Ara, Gal, Man, Rha, Fuc, GalUA and GluUA in ratio of 34.95:8.7:9.55:4.55:5.0:1.45:12.7:7.65. The structure of MSP-II was furtherly analyzed by FT-IR spectrum and 1 H and 13 C NMR spectroscopy, the results showed that MSP contained β glycosidic bonds as well as Α glycosidic linkages. In vitro tests proved that MSP-II could not only promote the proliferation and phagocytosis of RAW264.7 cells, but also induce the section of nitric oxide (NO) of macrophages. Consequently, the polysaccharide has a potent immunomodulatory activity by stimulating macrophages and can be considered as a novel potential immunopotentiator in medical and food industries.

Yan, Jing-Kun published the artcileEffect of different drying methods on the product quality and bioactive polysaccharides of bitter gourd (Momordica charantia L.) slices, Category: alcohols-buliding-blocks, the main research area is drying polysaccharide bitter gourd antioxidant antidiabetic; Bioactivity; Bitter gourd (Momordica charantia L.); Drying method; Physicochemical property; Polysaccharide.

In this study, three drying methods, namely, hot-air drying, freeze drying (FD), and IR radiation drying (ID), were applied to dry bitter gourd (Momordica charantia L.) slices. Results showed that the drying methods had significant influences on appearance, color, rehydration ratio, and microstructure of dried bitter gourd. FD provided high-quality dried bitter gourd products due to the uniform honeycomb network and less collapsed structure. Three water-soluble bitter gourd polysaccharides (BPS-H, BPS-F, and BPS-I) were obtained from the bitter gourd dried using the three drying methods. The three polysaccharides exhibited similar preliminary structural characteristics with different monosaccharide compositions and mol. weights BPS-I obtained from ID-dried bitter gourd had higher sugar and uronic acid contents than BPS-H and BPS-F. BPS-I exhibited stronger antioxidant activities and bile acid-binding capacity in vitro than BPS-H and BPS-F. Moreover, BPS-F and BPS-I showed significant α-amylase inhibitory activities in vitro.

Hajji, Mohamed published the artcileA water-soluble polysaccharide from Anethum graveolens seeds: Structural characterization, antioxidant activity and potential use as meat preservative, Formula: C6H12O6, the main research area is Anethum graveolens seed water soluble polysaccharide antioxidant meat preservative; Anethum graveolens; Antioxidant ability; Structural characterization; Turkey sausages preservation; Water-soluble polysaccharide.

A novel water-soluble polysaccharide named AGP1 was successfully isolated from seeds of Anethum graveolens by hot water extraction and further purified by DEAE-Sepharose chromatog. AGP1 has a relative mol. weight of 2.1 104 Da determined by Ultra-high-performance liquid chromatog. (UHPLC). The AGP1 characterization was investigated by chem. and instrumental anal. including gas chromatog. mass spectrometry (GC-MS), Fourier transform IR (FT-IR) spectroscopy and X-ray diffraction. Results showed that AGP1 was mainly composed of glucose, galactose, mannose and arabinose in a molar percent of 54.3, 23.8, 14.7 and 7.2, resp. The thermogravimetry anal. (TGA) and the differential scanning calorimetry (DSC) were used and showed that AGP1 has good thermal stability until 275°C. Moreover, the purified polysaccharide demonstrated an appreciable in vitro antioxidant potential. The addition of the AGP1, particularly at 0.3% (weight/weight), in turkey sausages instead of ascorbic acid, as preservative, reduced the lipid peroxidation, preserved the pH and color and improved the bacterial stability during cold storage at 4°C for 12 days. Overall, the results showed that the AGP1 deserves to be developed as functional and bioactive components for the food and nutraceutical industries.

The present study focused on production, optimization and characterization of exopolysaccharide (EPS) from Weissella confusa MD1. The purified EPS MD1 was also evaluated for in vitro biol. activities. The maximum yield of EPS (10.07 ± 0.32 g/L) was obtained with optimized culture conditions of 35°C at pH 6.5 for 36 h with 4% (w/v) galactose and 1% (w/v) ammonium nitrate supplemented in MRS broth. The crude EPS was purified with diethylamino ethanol-Sepharose Fast Flow column and Sephadex-G 75 column. The physicochem. and functional characterization of the EPS was done by high-performance thin-layer chromatog. (HPTLC), high-performance gel permeation chromatog. (HPGPC), Fourier transform IR (FTIR) spectroscopy, NMR (NMR), thermo gravimetric and differential scanning calorimetric (TG-DSC) anal., x-ray diffraction (XRD) and SEM (SEM). HPGPC anal. showed mol. weight of purified EPS MD1 as 2.909 KDa. Monosaccharide anal. showed that EPS was a novel mannan with mannose as the only monomeric unit present, suggesting EPS to be a homopolysaccharide containing → 6) α-Man p (1 → linkages. Microstructure studies by SEM showed MD1 EPS has globular and porous structure. The purified EPS MD1 exhibited higher thermal stability having degradation temperature around 267.74°C with melting enthalpy value (Δ H) of 337.7 J/g. The EPS showed promising antioxidant activities with excellent antibiofilm activity against Staphylococcus aureus, Listeria monocytogenes, Salmonella enterica and Salmonella typhi. These striking physicochem. characteristics features and bioactivities of EPS would serve as potential candidate in food processing industry to be used as food adjunct in foods with health benefits. This is the first study reporting a mannan homopolysaccharide from Weissella sp. to be structurally characterized.

Di Carluccio, Cristina published the artcileCharacterisation of the Dynamic Interactions between Complex N-Glycans and Human CD22, Related Products of alcohols-buliding-blocks, the main research area is autoimmune disease B cell malignancy CD22 N glycan; N-glycans; NMR spectroscopy; Siglecs; molecular recognition; sialic acids.

CD22 (Siglec-2) is a B-cell surface inhibitory protein capable of selectively recognising sialylated glycans, thus dampening autoimmune responses against self-antigens. Here we have characterised the dynamic recognition of complex-type N-glycans by human CD22 by means of orthogonal approaches including NMR spectroscopy, computational methods and biophys. assays. We provide new mol. insights into the binding mode of sialoglycans in complex with h-CD22, highlighting the role of the sialic acid galactose moieties in the recognition process, elucidating the conformational behavior of complex-type N-glycans bound to Siglec-2 and dissecting the formation of CD22 homo-oligomers on the B-cell surface. Our results could enable the development of addnl. therapeutics capable of modulating the activity of h-CD22 in autoimmune diseases and malignancies derived from B-cells.
