Aromatic emulsion beverage catering and industrial production
(2015) Lugovska, Oksana; Sidor, Vasyl
This article describes the use of emulsions for the production of beverages for for the restaurant business and industry. This paper describes the physico-chemical principles underlying the functional role of hydrocolloids in oil-in-water emulsions.The procedure of emulsion preparation with hydrocolloids which are stabilizer-emulsifiers, namely gum-arabic and starch, was updated by introducing new technological parameters. The food emulsion samples were investigated by their stability in beverages during their term storage. The optimum ratio between aqueous stabilizer and oil phase is characterized by maximum number of emulsion particles with the size under 1 micron.

(Lugovska, O. Effect of starch ashydrocolloids, the formation of a stable emulsion system in food / O. Lugovska, V. Sydor // Ukrainian food journal : internatinal scientific journal. – 2014. – Vol. 3. Issue 2. – P. 202–210., 2014) Lugovska, Oksana; Sidor, Vasyl; Kostova, Iliana
The investigated properties of native starch in the emulsion show that their use in manufacturing processes may result in the blocking of heat exchangers (due to high peak viscosity), and the viscosity at the output of the production process with varying and unpredictable depends on the combination of temperature and mechanical stress. This makes the use in the production of modified starches, which pobut combines two types of modifications: stabilization and the stitching. Important is the number of active links per molecule of starch. Such starches are characterized by high resistance to the process conditions (temperature, homogenization, effects of acidic). In each case, selecting the optimal starch, should take into account the specific conditions of the process.

Functional role of hydrocolloids in oil-in-water emulsions during storage of food
(2015) Lugovska, Oksana; Sidor, Vasyl
This paper describes the physic-chemical principles underlying the functional role of hydrocolloids in oil-in-water emulsions. Basic terms such as emulsifier and stabilizer are defined, and the origins of electrostatic and steric interaction potentials arc explained. The paper discusses the main factors controlling flocculation, creaming, coalescence and Ostwald ripening, distinguishing between the differing effects of adsorbing and no adsorbing hydrocolloids. The attention is specifically directed towards new understanding concerning the rheological and microstructural control of emulsion stability by non-adsorbing hydrocolloids, and the great potential of electrostatic protein-polysaccharide interactions at the oil-water interface for enhancing emulsion properties.
Hydrocolloids effect on the quality of oil-water emulsion for foodstuffs and beverages
(2016) Lugovska, Oksana; Sidor, Vasyl
The procedure of emulsion preparation with hydrocolloids which are stabilizer-emulsifiers, namely gum-arabic and starch, was updated by introducing new technological parameters, such as oil : aqueous phase ratio, sequence and parameters of ingredients introduction, parameters of pre-emulsion preparation and homogenization. The food emulsion samples were investigated using different amounts of gum-arabic and starch at constant amount of oil phase and samples with variable amount of oil phase and constant amount of a stabilizer. The optimum ratio between aqueous stabilizer and oil phase is characterized by maximum number of emulsion particles with the size under 1 micron.

Influence of gum arabic and starch as hydrocolloids on the quality of emulsion type oil-water in food
(2014) Lugovska, Oksana; Sidor, Vasyl
The paper systematically describes the basic theoretical information about the improvements in the production of emulsions. We consider the theory of a stable emulsion system, namely the particular use of raw materials and their properties analyzed the conditions necessary for the process of homogenization. And based on this, a large number of existing theories determined the most effective, which is used for the production of emulsions. Much attention is paid to the use of different stabilizers receipt of test data required for the calculation formulas finished products, and technological design process of emulsions. To assign these methods are used two stabilizers: gum arabic and modified starch, which when used for stability during storage of emulsions yield different results. Of great importance for the stability of these products is the size of the particles. The diameter of the emulsion depends on a process of manufacturing technology. More detail the process of homogenization of emulsions. For the features of this process are a few examples that will visually see the results emulsion stability during storage. Based on the processed foreign sources give modern technology and types of equipment for the homogenization process, with reference to the drawings, which will assimilate the information produced. We consider the design features of these devices, their advantages and disadvantages.

Beverage emulsions containing particles with a size of 1-1000 nm, and treated as objects of classical colloid chemistry. Of great importance to the stability of food products has a particle size. The use of emulsions in the manufacture of beverages is associated with the possibility of reducing the length of the production process while reducing power consumption compared to traditional production methods. This difference is particularly useful in food industry, because of the emulsions are the necessary ingredients that provide flavor, color and aroma of food that greatly simplifies their production technology.
