摘要:
Biomimetic dynamic membrane (BDM) has been" employed as a promising membrane separation technology regarding water/wastewater treatment (Model pollutant is methylene blue). Given its catalytic function on micro-pollutant removal and fouling control, detailed mechanism for impacts of fabrication method, carriers (CNT and GO) and laccase on the construction of biomimetic layer and enzyme immobilization have not been clear so far. In this work, the BDM performance with various fabrication methods, carriers and laccase were investigated and verified. The BDM fabrication tests demonstrated that BDM with mixed filtration method had better filtration performance (up to 120 L m(-2) h(-1) flux and 80% removal rate) than BDM with stepwise filtration method. Moreover, the laccases immobilized on GO exhibited a stronger laccase activity than those on CNT. Increasing CNT or GO dosage strengthened removal rate, but lowered flux, meanwhile flux and removal rate exhibited a significant fluctuation with certain laccase dosage. At 25 g m(-2) CNT or GO dosage and 50 g m(-2) laccase dosage, the optimized flux and removal rate values were obtained. Further study investigated the surface morphology and property of BDM, showing that BDM with mixed filtration method turned out to be the optimized enzyme immobilization mechanism and fabrication method. In addition, during multiple filtration cycles, with the optimized conditions, the removal rate, flux and laccase activity of BDM could maintain at high levels. On account of the finding of the present study, selecting a suitable fabrication method, appropriate CNT or GO dosage and laccase dosage can indeed optimize the structure of biomimetic layer and enzyme immobilization, expanding its possibility on sustainable operation.

摘要:
Saponins are a class of glycosides whose aglycones can be either triterpenes or helical spirostanes. It is commonly recognized that these active ingredients are widely found in various kinds of advanced plants. Rare saponins, a special type of the saponins class, are able to enhance bidirectional immune regulation and memory, and have anti-lipid oxidation, anticancer, and antifatigue capabilities, but they are infrequent in nature. Moreover, the in vivo absorption rate of saponins is exceedingly low, which restricts their functions. Under such circumstances, the biotransformation of these ingredients from normal saponins-which are not be easily adsorbed by human bodies-is preferred nowadays. This process has multiple advantages, including strong specificity, mild conditions, and fewer byproducts. In this paper, the biotransformation of natural saponins-such as ginsenoside, gypenoside, glycyrrhizin, saikosaponin, dioscin, timosaponin, astragaloside and ardipusilloside-through microorganisms (Aspergillus sp., lactic acid bacteria, bacilli, and intestinal microbes) will be reviewed and prospected. © 2019 by the authors.

摘要:
The physicochemical properties, biological functions and microbial degradation of inulins differ according to their degree of polymerization. However, the relationship between inulin activities and its effect on gut microbiota remains unknown. In this study, high fat diet with inulin (1 or 5 g/kg·bw), either with short or long chains groups were administered to different groups of mice (n = 10) for 10 weeks in order to investigate the effect of inulin on the microbial diversity of the animals. Litchi pericarp procyanidins (LPPC) were used for comparison purposes. Furthermore, the lipid metabolism and key regulator genes in mice were determined. The results indicated that natural inulin (1 g/kg·bw) ingestion reduced the body weight of fat mice between week 6–9. Glutathione peroxidase (GSH-Px) activity in liver was remarkably higher after adding long chain inulin (5 g/kg·bw) compared to high-fat-diet mice. Moreover, high dose of natural inulin regulated malondialdehyde and advanced glycation end-products levels in mice liver. Likewise, the high dose of short-chain inulin increased sterol response element binding protein 1 (SREBP-1), β-Hydroxy β-methylglutaryl-CoA (HMG-CoA) and ATP-binding cassette transporter A1 (ABCA1) genetic expression. A significant change on the abundance of six genera in gut microbial profile suggested that inulin has the ability to modulate the lipid metabolism regardless of chain length, mainly due to its impact on colon microbiota variety. © 2019

摘要:
It has been proven that A-type procyanidins, containing an additional ether bond, compared to B-type procyanidins are also bioavailable in vitro and in vivo. However, their bioavailability and absorption in the gastrointestinal tract remain uncertain. In this study, a model of the human adenocarcinoma stomach cell line (MKN-28) was established to explore the cellular transport of flavanolic monomers and procyanidin dimer A2, which were isolated from the litchi pericarp extract. After the integrity and permeability of the cell monolayer were ensured by measurement of the transepithelial electrical resistance and the apparent permeability coefficient for Lucifer yellow, the transportation of procyanidins A2 and B2, (-)-epicatechin (EC), and (+)-catechin (CC) was studied at pH 3.0, 5.0, or 7.0 in the apical side, with compound concentrations of 0.05 and 0.1 mg/mL based on the cytotoxicity test. High-performance liquid chromatography and liquid chromatography-mass spectrometry analyses indicated that EC, CC, and A2 were transported in the MKN-28 cell line from 30 to 180 min, while B2 showed no transport. The maximal transport efficiencies of EC, CC, and A2 were 23 ± 0.81, 13.16 ± 1.53, and 16.41 ± 1.36%, respectively, existing at 120, 180, and 120 min of transportation. Laser scanning confocal microscopy analysis presented the dynamic transmission of EC, in accordance with the result of concentration determination, suggesting that the A-type procyanidins are possibly absorbed through the stomach barrier, which is pH- and time-dependent. © 2019 American Chemical Society.

摘要:
Selenium is an essential trace element in human body, and kappa-selenocarrageenan (Se-car) is an organic source of selenium supplement. To further utilize Se-car in food packaging, biotherapy or biosensor, the molecular information of Se-car was characterized here and multi-functional Ag NPs synthesized by Se-car were fabricated. Results of GPC-MALLS, FTIR, potentiometric titration, and intrinsic viscosity showed that Se-car was polymerized by nearly 22 basic units of disaccharide. Sixty-four percentage of sulfated groups (SO42-) in carrageenan was replaced by selenium acid (SeO32-), which belonged to weak acid resulting from a gradually decrease of zeta-potential with acidity process to pH 1.0. Besides, the capacity of biosynthesis silver nanoparticles (Ag NPs) by Se-car was studied and it made a comparison with kappa-carrageenan. Results exhibited that Se-car could serve as an efficient reducing and capping agent for Ag NPs fabrication (remarked as Se-car@Ag). The k(app) of Se-car@Ag NPs for catalyzing 4-NP degradation was 2.14 x 10(-2) s(-1). Antibacterial test revealed Se-car@Ag had an ability to inhibit the growth of Escherichia coli and Staphylococcus aureus. To combine the selenium health benefit and functional metal nanoparticles, Se-car@Ag might have potential applications in multiple areas like medicine, disease diagnostic, and drug delivery.

摘要:
Purple sweet potato anthocyanins are common natural pigments widely used in food industry, while they are often thermally processed in application. Degradation of anthocyanins, formation of polymers and color changes of purple sweet potato extract (PSPE) were investigated at 90 degrees C in the range of pH 3.0-pH 7.0. Data analysis indicated a first-order reaction for anthocyanins degradation in solutions with pH 3.0, 5.0 and 7.0 have half-lives of 10.27, 12.42 and 4.66h, respectively. The polymeric color formation followed zero-order kinetics, progressively increasing with pH values. The color of PSPE were changed with heating time and pH value through visual observation and colorimetric characterization. Analysis by UV-Vis spectrophotometry and HPLC indicated that anthocyanins in solution with pH 3.0 changed from monomeric anthocyanin into new polymers during heat treatment. Degradation of anthocyanins was accompanied by an increase in polymeric color index, due to the formation of melanoidin pigments and condensation reactions.

Adsorption;Complex enzymatic hydrolysis;Porous purple sweet potato starch
摘要:
This study aimed to develop a facile synthesis process of porous starch wall materials from purple sweet potato (PSP) for microencapsulation via enzymatic treatment. The optimum extraction conditions of purple sweet potato starch (PSP-S) were first attained by an orthogonal experiment. Response surface methodology was performed through the enzymatic hydrolysis of PSP-S using an α-amylase and glucoamylase complex to optimize the process parameters for the production of porous starch. Optimal reaction conditions were: the mass ratio (w/w) of glucoamylase to α-amylase of 6.39, amount of substrate of 19.5 g, and amount of enzymes of 0.53%. The surface morphology, microstructure, and thermal stability of the obtained samples were characterized with scanning electron microscopy, Fourier-transform infrared, and thermogravimetric analyses, respectively. The purple sweet potato porous starch (PSP-PS) had a stable oil adsorption capacity, and the molecular structure and thermal stability of porous starch were not substantially different from those of native starch. This study offers a simple yet efficient approach to produce fully biodegradable food-based porous materials for potential applications in oil microencapsulation. © 2019 North Carolina State University.

摘要:
Background: The genus Chaenomeles Lindley (Chaenomeles), known as Mugua (in Chinese), is a medicinal and edible plant that is considered a functional source for human health promoting. Numerous bio-, chemical- and physical technologies have been applied to explore the relationship between the phytochemistry of Chaenomeles and their bioactivities, opening the door to their potential application in the field of function food and traditional Chinese medicine. Scope and approach: This paper aimed to systematically summarize available information on Chaenomeles and provide reference for further investigations. The extracted and isolated chemical constituents (e.g., triterpenoids, sesquiterpenoids, flavonoids, organic acids, phenolic compounds, volatile oil and fatty acids) from five species of Chaenomeles were mainly summarized. This review highlights the theoretical aspects and recent developments of nonconventional extraction (microwave, ultrasound and enzyme-assisted extraction, super- and subcritical fluid extraction and solid phase extraction) technologies for bioactive compounds recovery from Chaenomeles. Additionally, scientific reports on crude extracts or pure compounds from this plant revealed broad bioactivities, including antioxidant, antimicrobial, antiinflammatory activities, as well as immunoregulatory and hepatoprotective effects. Key findings and conclusions: Approximately 150 chemicals have been characterized from different parts of Chaenomeles. Triterpenoids, flavonoids and phenolic compounds are the major bioactive ingredients of this plant. Additionally, the crude extracts and monomer compounds have been demonstrated with various in vitro and in vivo pharmacological functions. Nonconventional extraction technologies have been proposed to provide efficient, systematic, and practical protocols for the sustainable valorization of Chaenomeles. © 2019 Elsevier Ltd

摘要:
油体是天然存在于油料作物种子中的储油器官,了解其稳定性和表面膜蛋白结构对油体的应用至关重要。选取白芝麻油体为研究对象,考察不同加工与贮藏条件(如p H、离子强度、温度)对芝麻油体稳定性的影响,并对芝麻油体膜蛋白进行结构表征。结果表明:酸性环境(pH≤5.0)和高盐离子浓度(≥0.2 mol/L)会加速油体的聚集和失稳,而碱性条件、高热处理和低盐离子浓度则有助于维持其稳定性。通过聚丙烯酰胺凝胶电泳(SDS-PAGE)、红外光谱(FTIR)及差示扫描量热法(DSC)分析,发现白芝麻的油体膜蛋白主要由12~14 ku的油体蛋白(Oleosin)和27 ku的油体钙蛋白(Caleosin)组成,油体膜蛋白的热变性温度约为55℃,α-螺旋为其主要二级结构。这些参数为开发基于芝麻油体和油体膜蛋白的产品提供了理论参考。

摘要:
Purple sweet potato anthocyanins are kinds of natural anthocyanin red pigments extracted from the root or stem of purple sweet potato. They are stable and have the functions of anti-oxidation, anti-mutation, anti-tumor, liver protection, hypoglycemia, and anti-inflammation, which confer them a good application prospect. Nevertheless, there is not a comprehensive review of purple sweet potato anthocyanins so far. The extraction, structural characterization, stability, functional activity, application in the food, cosmetics, medicine, and other industries of anthocyanins from purple sweet potato, together with their biotransformation in vitro or by gut microorganism are reviewed in this paper, which provides a reference for further development and utilization of anthocyanins. © 2019 by the authors.

摘要:
High throughput genome sequencing has revealed a multitude of potential secondary metabolites biosynthetic pathways that remain cryptic. Pathway reconstruction coupled with genetic engineering via heterologous expression enables discovery of novel compounds, elucidation of biosynthetic pathways, and optimization of product yields. Apart from Escherichia coli and yeast, fungi, especially Aspergillus spp., are well known and efficient heterologous hosts. This review summarizes recent advances in heterologous expression of microbial secondary metabolite biosynthesis in Aspergillus spp. We also discuss the technological challenges and successes in regard to heterologous host selection and DNA assembly behind the reconstruction of microbial secondary metabolite biosynthesis.

摘要:
BACKGROUND: A pilot scale process consisting of ultrasound-assisted extraction, ammonium sulfate precipitation, cross-flow ultrafiltration and AB-8 macroporous resins purification aiming to recover anthocyanins and zein from purple corn (PC) was optimized and scaled-up. The effects of five independent variables (ethanol concentration, liquid to solid ratio, ultrasound temperature, time and power) were discussed and the most influential factors were optimized. RESULTS: The highest total anthocyanin (0.45 ± 0.01 g kg−1) and zein (17.14 ± 1.73 g kg−1) contents from purple corn were obtained using an ultrasound power of 105 W, an extraction time of 90 min, an ethanol concentration of 74% and a liquid to solid ratio of 26:1, at 70 °C, and this was consistent with the predicted values (0.46 and 17.36 g kg−1, for anthocyanin and zein, respectively). Subsequently, ammonium sulfate precipitation was used to isolate anthocyanins and zein. After cross-flow ultrafiltration, zein (6.30 g) was obtained with 80% purity. Anthocyanins were purified by AB-8 macroporous resins, resulting in 1.60 g of anthocyanins. High-performance liquid chromatography-electrospray ionization-mass spectrometry analysis revealed eight different anthocyanins in purple corn extracts. CONCLUSION: From the results obtained in the present study, it can be concluded that the proposed extraction–separation–filtration–purification method applied under the optimal conditions could be scaled-up to recover anthocyanins and zein simultaneously. Moreover, under the selected conditions, no significant degradation of anthocyanins was observed. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry

摘要:
Catalysts play a key role in the production of cellulose acetate (CA). In this study, CA derived from bamboo cellulose (BC) was synthesized in a solution mixture of acetic acid and acetic anhydride that contains catalysts. The catalytic activities of three catalysts (i.e., sulfuric, methyl benzene sulfonic, and dodecyl benzene sulfonic acids) were investigated in terms of kinetics of acetylation, which was established according to the first-order reaction mechanism. Based on this, cellulose-based nanofibers were further prepared from the acetylated BC solution using an electrospinning technique. Results in this study may be useful for the preparation and application of nanomaterials derived from natural polymeric materials. © 2017, Springer Science+Business Media B.V., part of Springer Nature.

摘要:
Rhizome knot is always wasted as useless and inedible part of lotus root, despite its abundance of polyphenols. In this work, enzyme-assisted extraction followed by ultra-filtration was investigated to recover polyphenols from rhizome knot. Cellulase and pectinase treatment enhanced the polyphenols extraction. The 100 kDa membrane resulted in better filtration yield than 50 kDa membrane, 3.84% and 3.37%, respectively. With 100 kDa membrane, the highest filtration yield (4.08%) was achieved with a rotational speed of 600 rpm, TMP of 0.3 MPa and pH of 5. Satisfied permeate turbidity (<3 NTU) and polyphenol transmission (>90%) were obtained under these conditions. The main polyphenols identified in both rhizome knot extract and permeate were: chlorogenic acid, B-type procyanidin dimer·H<inf>2</inf>O, (+)-Catechin, B-type procyanidin dimer, (−)-Epicatechin, propyl gallate·H<inf>2</inf>O, caffeic acid, (−)-Epicatechin-3-gallate, and rutin. Membrane fouling led to the most important resistance (58% of total resistance). Scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) evidenced that protein accumulation was the main fouling cause.<br/> ©2018
