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.
