Molasses, a byproduct of the sugar industry, presents multicomponent system of complex chemical composition and a suitable raw material for a range of food technology. The composition of molasses is conditioned by the sugar beet quality, applied beet processing technology and used aids. The main parts of molasses consists carbohydrates, primari...

The recent I-U measurements on the individual micro needle-shaped crystals, of the ternary mixed valence compound In5Se5Cl, crystallizing in the monoclinic crystal system (P21/m), showed significant light sensitivities. Micro needles of In5Se5Cl “glued” on Si- and Cu- substrates were measured under five different wavelengths with variou...

Meat is very important ingredients in the human diet, so it is a source of easily digestible, biological and energy valuable components. Therefore, this paper investigate the influence of temperature in the temperature range from 51°C to 100°C and different methods of thermal processing, thermal treatment by cooking and roasting, to change ...

In this paper the content of metal in drinking water was determined in two samples, one from 2008 and other from 2010, by the indirect method based on the analysis of scale, which had originally been suggested by Rajkovic and associates. Received results confirmed that drinking water according to the metal content was of constant level (metals are ...

For the prediction of formation of non-ferrous processing and accumulating waste both model of balancing and model of correlation and regression analysis can be employed, while the dynamic model can be applied only for the accumulating waste. Estimates of the formation of certain type of metallic secondary raw materials in model of balancing are ba...

Efflorescence is a crystalline deposit of water soluble salts on the surface of ceramic masonry. In most cases, efflorescence can be removed by various cleaning methods depending on the chemistry of the crystalline deposit. But this, sometimes, may even worse the problem. Therefore, it would be most desirable to minimize or to prevent the effloresc...

Marigold (Calendula officinalis L.) defined the particle size was extracted using 40, 50 and 60% ethanol as a solvent by classical procedure of maceration. The kinetics of extraction by given ethanol concentrations in relation to drug:solvent = 1:10 was studied. The quantity of total substances (q0, g/100g drugs), and the quantity of the residue su...

High concentrations of sulfide in (cumulative) tannery wastewater are the direct cause of very high toxicity of this effluent. Therefore it is necessary to remove this pollutant by the oxidation process. Hydrogen-peroxide is the oxidizing agent, which increasingly acts as an "environment friendly" due to multiple uses for purification, detoxificati...
