Abstract:

The samples were prepared to study the influence of pH on the formation and stability of thaumasite using Fourier transform infrared and X-ray diffraction to analyze the composition of the samples. The erosion solutions with the pH arranged from 9.5 to 13.5 prepared by sodium bicarbonate, sodium hydroxide and 5% sodium sulfate. The experimental data for three years has been given in the paper. The result of the research indicates that the value of pH at 10.5 is the optimum pH for the forming of thaumasite and when the pH comes up to 11.5, thaumastie can form but it will decompose in the soluti

Abstract:

Aqueous extracts of the aril of the seed of Thaumatococcus daniellii contain, in addition to the intensely sweet protein thaumatin, a cysteine protease that we have termed thaumatopain. Thaumatopain has been purified by ion-exchange chromatography from arils, and is a monomeric protein of Mr 30,000. The protease strongly resembles papain in proteolytic activity, pH optima, susceptibility to inhibitors of cysteine proteases and in N-terminal sequence. The protease has also been identified in crude aril extracts by affinity labelling with iodo[14C]acetate. Thaumatopain is responsible for the cys

Abstract:

Thaumatin, commercially available under the trade name Talin, is known as a sweetest compound (100,000 times sweeter than sucrose on molar basis) which can be used not only as a sweetener but also as a flavor enhancer. This sweetener is a protein found in plant Thaumatococcus daniellii. Biotechnology has also seen as alternative method of production of thaumatin. The plant source of this protein is limited and very expensive. Although the sweetener is the sweetest one, its application is not so common because of its liquorice taste and delayed sweetness.

Abstract:

The exposure of cement to high concentration of sulphate anions for a prolonged time period can lead to the formation of secondary ettringite and thaumasite. The preparation of synthetic ettringite is described in this paper.

Abstract:

The thaumasite form of sulfate attack of cementitous material (TSA) is a new kind of sulfate attack and it is more harmful than traditional sulfate attack. By means of Fourier transform infrared (FT-IR) and X-ray diffraction (XRD), the effect of dosage and fineness of fly ash on TSA of cementitous material were investigated in this paper. The specimens had been immersed in magnesium sulfate solution of 5% mass concentration at 5±2° C for three years. The results showed that fly ash could not restrain the formation of thaumasite but it delayed the occurrence of TSA in cementitous material when

Abstract:

AbstractVitis vinifera L. is adapted to a very variable range of climates but it mostly grows in the temperate regions of continental Europe. In the Slovak Republic, the Tokaj wine region is one of the territories, where wine production is concentrated. Grape is a popular fruit and when processed, it is used as musts, juices or wine. Some people may suffer from allergic reactions to grapes. Up to now, endochitinases, lipid-transfer protein, and thaumatin were identified as grape allergens. In this study, expression of chitinase and thaumatin allergen was analysed in the grapes of Tokaj region
