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 ...
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 ...
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 ...
Structure and optical properties of noble metal and oxide nanoparticles dispersed in various polysaccharide biopolymers
(Spie-Int Soc Optical Engineering, Bellingham, 2011)
We present the results on the structure and the optical properties of noble metal (Ag, Au) and oxide (ZnO) nanoparticles synthesized by various methods in different polysaccharide matrices such as chitosan, glycogen, ...
