World Journal of Gastroenterology 2009年第16期15卷 1977-1984页

作者： Carmen Frontela Maria Laura Scarino Simonetta Ferruzza Gaspar Ros Carmen Martínez Department of food science and Nutrition Faculty of Veterinary Science and Food Science and TechnologyMurcia University INRAN National Research Institute for Food and Nutrition

AIM： To test the effect of the dephytinization of three different commercial infant cereals on iron, calcium, and zinc bioavailability by estimating the uptake, retention, and transport by Caco-2 cells. METHODS： Both dephytinized （by adding an exogenous phytase） and non-dephytinized infant cereals were digested using an in vitro digestion protocol adapted to the gastrointestinal conditions of infants younger than 6 too. Mineral cell retention, transport, and uptake from infant cereals were measured using the soluble fraction of the simulated digestion and the Caco-2 cells. RESULTS： Dephytinization of infant cereals significantly increased （P 〈 0.05） the cell uptake efficiency （from 0.66%-6.05% to 3.93%-13%）, retention （from 6.04%-16.68% to 14.75%-20.14%） and transport efficiency （from 0.14%-2.21% to 1.47%-6.02%）, of iron, and the uptake efficiency （from 5.0%-35.4% to 7.3%-41.6%） and retention （from 4.05%-20.53% to 14.45%-61.3%） of zinc, whereas calcium only cell uptake showed a significant increase （P 〈 0.05） after removing phytate from most of the samples analyzed. A positive relationship （P 〈 0.05） between mineral solubility and the cell uptake and transport efficiencies was observed. CONCLUSION： Removing phytate from infant cereals had a beneficial effect on iron and zinc bioavailability when infant cereals were reconstituted with water. Since in developing countries cereal-based complementary foods for infants are usually consumed mixed with water, exogenous phytase additions could improve the nutritional value of this weaning food.

Journal of Materials science & Technology 2003年第6期19卷 599-603页

Rice husk was used to prepare the silica of amorphous nature being several times more reactive than that obtained from the mineral kingdom. Number of rice husk batches were pyroprocessed under varying time-temperature parameters for this purpose. The ash resulting from a batch pyroprocessed at 500℃ for 8 h contained 92.01% silica. It was upgraded to 98.50% by applying physicochemical purification procedures. The mineral, wollastonite (CaSiO3), was synthesized from thus prepared silica and limestone containing 55.91% CaO. Solid state reaction, between CaO and SiO2 was attempted at different temperatures in the presence of a mineralizer. The sintering temperature, for affecting the said synthesis, was ranged between 900℃ to 1300℃ with the steps of 100℃. Specific chemical analysis techniques were applied to determine the effectiveness of carried out reaction and promising batches were subsequently subjected to XRD investigations. The produced mineral was also characterized regarding its physical properties like: colour, hardness, melting point and specific gravity. Percent yield of the produced wollastonite was also estimated and compared with that of obtained by other researchers who synthesized it by using silica from mineral kingdom. Batches sintered at 1200℃ and 1300℃ for 1 h showed the overall best results.

Surface Activities of Calix [4]resorcinarenes Bearing Four Hydrophobic Chains and Its Solubilization for Organic Compounds

引用

Chemical research in Chinese Universities 2002年第2期18卷 206-210页

作者： LI Bo Yoshifumi KOIDE Kunio ESUMI Toyota Central R&D labs. Inc.411YokomichiNagakuteAichi 4801192Japan Departemnt of Applied Chemistry and Institute of Colloid and Interface science Science University of Tokyo

Calix resorcinarenes bearing four hydrophobic side chains ( Ar-Rn, Ar-Ph, and Ar-N) orient stably on water oil interface and show high solubilization capacities for organic compounds, such as long chain alcohols, benzene, toluene and dyes. The capacities are high even near the cmc of polyalkylated calix resorcinarenes, but the solubilities of organic compounds(solubilizates) decrease with the increase of the size of the solubilizates. Ar-R 6, with a chain length of six carbons, is the most effective among Ar-R n , Ar-Ph, and Ar-N; 11 fold mol of hexanol is dissolved in 2×10 -3 mol/L Ar-R 6. Moreover, Ar-R n bearing four alkyl side chains solubilizes the chain alcohols of the same chain length mostly. The solubilization capacities are presumably brought by inclusion in a large cavity of the polyalkylated calix resorcinarenes and by an efficient orientation of the solubilizates.

Study on the Epigallocatechin Gallate and Konjac Glucomannan Mosaic Topological Structure

Chinese Journal of Structural Chemistry 2017年第9期36卷 1447-1455页

作者：洪馨倪永升林婉媚穆若郡王林庞杰吴春华温成荣 College of food science Fujian Agriculture and Forestry University School of food science and Technology National Engineering Research Center of SeafoodDalian Polytechnic University

In order to effectively protect the activity of Epigallocatechin gallate（EGCG）, we explored the protection mechanism of Konjac glucomannan（KGM） for EGCG by experiments and theory analyses. We synthesized KGM/EGCG nanofibers by using electrostatic spinning method. The microstructure of nanofibers was characterized by SEM, FTIR, TGA, XRD and Raman spectroscopic. The formation mechanism and the protection effects of KGM/EGCG nanofibers were also discussed. The results showed that the EGCG activity was protected due to the hydrogen bonds between-OH of EGCG and KGM, and EGCG was embedded in KGM nanofiber with bead style. The reducing force and DPPH scavenging ability data indicated that KGM/EGCG nanofibers have stronger antioxidant activity than the EGCG solution under the same condition. Hence, the mosaic topological structure of KGM can effectively extend the EGCG activity.

Journal of Integrative Agriculture 2013年第11期12卷 1937-1945页

作者： Luca Rotolo Francesco Gai Silvana Nicola Ivo Zoccarato Alberto Brugiapaglia Laura Gasco Department of Agricultural Forest and Food Sciences(DiSAFA)University of Turin Institute of science of food Production National Research Council

The aim of this research was to evaluate the dietary supplementation 1% （w/w） of oregano and sage dried leaves on performances and meat quality of broiler rabbits. A feeding trial, which lasted 48 d, was carried out on 105 male Bianca Italiana rabbits randomly divided in seven groups and fed ad libitum. At the end of the trial ten animals per group were slaughtered and samples of dorsal muscle were taken in order to perform laboratory analysis. Mortality rate did not statistically differ between groups. Growth performances of animals fed diets supplemented with aromatic plants were higher （P〈0.05） than those of animals of control group, whereas carcass parameters were not affected by treatments excepting for the slaughter weight that showed the same trend as growth performances. Meat quality traits, oxidative lipid stability and fatty acid proifle were not inlfuenced by aromatic plant supplementation. In conclusion, oregano and sage in form of dried leaves can be used in rabbit without adverse effects on performance, carcass characteristics and meat quality traits.

BIOPOLYMER BASED NANO-DELIVERY SYSTEMS FOR ENHANCING BIOAVAILABILITY OF NUTRACEUTICALS

引用

Chinese Journal of Polymer science 2013年第9期31卷 1190-1203页

作者： Bing Hu Qing-rong Huang College of food science and Technology Nanjing Agricultural University Department of food science Rutgers University

Recently, there has been an increasing interest in the development of efficient food-grade oral nano-delivery systems for encapsulation, protection and target delivery of nutraceuticals to enhance their bioavailability, fiarther to prevent disease and promote human health and well-being. food proteins represent promising candidates for efficient nutraceutical nanocarriers due to their exceptional characteristics, namely biodegradability, nonantigenicity, high nutritional value, abundant renewable sources and extraordinary binding capacity to various nutraceuticals. In addition, their biocompatibility, biodegradability, low toxicity, low cost, and non-starch polysaccharides possess many favourable characteristics such as stability in the harsh gastric environment, resistance to digestive enzymes, and mucoadhesiveness to intestinal mucosal surface. This review describes the design and formation of nanoscaled delivery systems for nutraceuticals using food-grade proteins （including peptides）, polysaccharides and their associative complexes. The toxicity and cellular uptake fate of the nanostructures, as well as their effects on the intestinal absorption of the encapsulated nutraceuticals were also discussed.
