Effect of HHP in Physicochemical Properties of Starch by NMR



Effect of high hydrostatic pressure (HHP) in physicochemical and textural properties of starch
Okur, İlhami; Alpas, Hami; Department of Food Engineering (2018)
Starch is the major polysaccharide consumed by human being. It is not classified as a dietary fiber as it is digestible by the enzymes present in the saliva and small intestines. However, it could become possible to modify the starch with thermal and non-thermal techniques. High Hydrostatic Pressure (HHP) is a cold pasteurization technique that has increased application in the food industry with minimum effect on the nutritional quality of the products. It is hypothesized that the use of HHP could be a modi...
Effect of TiO2 addition on the crystallization and tribological properties of MgO-CaO-SiO2-F2O5-F glasses
Park, Jongee; Öztürk, Abdullah (2008-04-10)
The kinetic parameters including the activation energy for crystallization (E), the Avrami parameter (n) and frequency factor (v) of a glass in the MgO-CaO-SiO2-P2O5-F system were studied using non-isothermal differential thermal analysis (DTA) with regard to small amount of TiO2 additions. It has been shown that the role of TiO2 changes from a glass network former to a glass network modifier with increasing TiO2 content in this system. The kinetic parameters of the crystallizing phases, apatite and wollast...
Effect of LiClO4 Salt on Dielectric Properties of Acrylonitrile-Methyl Methacrylate and Acrylonitrile-Isobutyl Methacrylate Copolymers
Poly(acrylonitrile-co-isobutyl methacrylate), PAN-co-PIBMA, and poly(acrylonitrile-co-methyl methacrylate), PAN-co-MMA copolymers are synthesized by emulsion polymerization. The structural characterization is done by FTIR and H-1-NMR spectroscopy and thermal analyses are performed by thermogravimetric analysis (TGA). After various amounts of LiClO4 salt loading into copolymer films, the dielectric properties of these films at different temperatures and frequencies are determined. The effects of different me...
Effect of Cr and Mo doping on the electrochemical properties of freeze-dried LiCoO2
Buyukburc, Atil; Aydınol, Mehmet Kadri (2014-10-01)
In this study, LiCoO2 is doped with 2 mol.% Cr and Mo in order to determine the effect of these elements on the electrochemical performance. Precursors are synthesized by means of freeze drying. Calcination is applied at 750 degrees C for 24 h. Doping content and calcination temperature as well as duration are very important for producing impurity-free layered LiCoO2. If the doping content is larger than 2 mol.% or when the calcination temperature is decreased to 550 degrees C, impurity phases are seen. As ...
