Study of lipase-catalyzed synthesis of ascorbyl oleate using response surface methodology
(6th Central European Congress on Food, CEFood 2012, 2012)
L-ascorbic acid has good antioxidative properties but its efficiency in stabilizing fats and oils in products with high lipid content is negligible due to its hydrophilic characteristics. On the other hand, fatty acid ...
Synthesis of ethyl cinnamate catalyzed by lipase B from Candida antarctica
(6th Central European Congress on Food, CEFood 2012, 2012)
Cinnamic acid and its esters are widespread throughout plant kingdom and therefore, they are common components of our daily diet. Ethyl cinnamate has been approved by FDA for direct addition to food for human consumption. ...

Investigation of probiotic potential of Leuconostoc sp. and Lactobacillus sp. natural isolates from non-commercial milk and water kefir
(6th Central European Congress on Food, CEFood 2012, 2012)
Non-commercial milk and water kefir grains (from a household in Belgrade, Serbia) were used for isolation of lactic acid bacteria on TSA, MRS and M17 agar. Preliminary identification has been performed according to ...
Application of nonlinear frequency response method for investigation of periodically operated chemical reactors
(Beograd : Mathematical Institute SANU, 2012)
Process intensification aims to increase the efficiency of processes in the chemical industry by development of new concepts of processing methods and equipments. One way to achieve better performance is to operate the ...
Microindentation hardness testing of different composite systems with thin electrodeposited nickel and copper films
(Belgrade : Military Technical Institute, 2012)
Thin Ni and Cu films with fine-grained structures have been electrodeposited from self-made sulphamate-based and sulphate-based electrolytes, respectively. DC electrodeposition of Ni films was performed on single crystal ...
Mechanochemically synthesized CaO·ZnO catalyst for biodiesel production
(20th International Congress of Chemical and Process Engineering, CHISA 2012 and 15th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction, PRES 2012, 2012)
The transesterification of triglycerides (vegetable oil) with methanol using CaO·ZnO mixed oxides catalyst were conducted to produce Fatty Acid Methyl Esters (FAME), i.e. biodiesel. The catalysts were used in the methanolysis ...
Effect of fermentation by Streptomyces sp. on antioxidant properties of spent coffee extracts
(6th Central European Congress on Food, CEFood 2012, 2012)
During espresso coffee preparation large amounts of spent coffee residues are produced and discarded daily as a part of the communal waste. However, there is a great potential in recycling this type of waste for extraction ...
