(University of Novi Sad, Institute of Food Technology, 2018)
The objective of this research was to study the production of sunflower meal protein hydrolysate
(SMPH) from sunflower meal protein isolate (SMPI) prepared by sedimentation/flotation and isoelectric precipitation of ...
Adsorptive, catalytic and antimicrobial applications of Serbian natural clinoptilolite
(Lublin University of Technology, Nadbystrzycka 40 20-618 Lublin, 2018)
Clinoptilolite is the most abundant natural zeolite in Serbia, and the Zlatokop deposit (near Vranjska Banja) is the largest deposit. The zeolitic tuff (CT) from Zlatokop contains >70 wt. % clinoptilolite with quartz and ...
Whey valorization using transgalactosylation activity of β-galactosidase
(University of Novi Sad, Institute of Food Technology, 2018)
Whey is the most significant by-product from the dairy industry that can cause serious environmental pollution problems. Namely, one of the main whey constituents is lactose, which is responsible for high biological oxygen ...
Optimization of solid-phase extraction for analysis of artificial sweeteners in water
(Beograd : Srpsko hemijsko društvo, 2018)
After decades of using artificial sweeteners in the food and pharmaceutical industry, their ubiquitous presence in the environment has been determined 1,2. These substances are recognized as emerging pollutants due to ...
Influence of the alkali treatment conditions on the chemical composition and capillarity of the jute woven fabrics
(Beograd : Serbian Chemical Society, 2018)
Jute fibers have been subjected to various types of chemical modifications to improve their suitability as textile materials. Among them, the alkali treatments have been widely used as the most direct and ecological chemical ...
Nanocomposite Hydrogels Based on Poly(vinyl alcohol) and Chitosan with Silver Nanoparticles and Graphene Aimed for Wound Dressing Applications
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
In this work, we prepared hydrogels based on PVA, CHI and Gr, and used them
as a porous matrix to synthesize silver nanoparticles by an in situ electrochemical
method [3,4]. The hydrogels were prepared from PVA/CHI/Gr ...
