Technology of flour confectionery products using emulsion obtained in conditions of cavitation processing

The idea of using the cavitation energy in food industry appeared in the middle of the last century, but due to absence of efficient machineries and developed process theory this method was not used. The attractiveness of using the effects of cavitation in the food industry lies in the possibility of a significant intensification of such most labour and energy-consuming processes as grinding, homogenization, dispersion, emulsification of food disperse systems. Nowadays, lots of works all around the world are dedicated to this phenomenon. This scientific direction has gained it's actuality with the world rate technic development allowing to create the more powerful machineries, capable to processing large volume of liquid. The development of new researching method has made the problem of using the cavitation energy – which has both hydrodynamic and acoustic nature – more attractive. The advantages of using the effects of cavitation on food media have been presented. The expediency of using cavitation in various sectors of the food industry: baking industry, meat industry and dairy industry has been proved. Specific examples have been given and the prospects of using this type of influence have been shown to ensure the stability of food emulsions. This study has shown how the change in the type, intensity and duration of the cavitation processing makes it possible to control the quality of the emulsion, test and finished bakery confectionery products. The optimal parameters of intensity and duration of ultrasound exposure have been determined: Imax = 1.24•106 cm2•s–3, t = 7 minutes, during which the maximum dispersion of all three phases (S-L-G) has been provided and the stability of the emulsion structure has been improved, which is confirmed by a decrease in the amount of undissolved sugar and formed foam. It has been established that the physicochemical effect of high energies leads not only to a decrease in the entropy of the leading processes and technological systems in general, but also to an increase in production efficiency and quality stabilization of the finished product.

Methods of optimizing technologies and recipe of oatmeal cookies

Oat has a special position among grain crops due to its amino acid and fatty acid composition which confirms the value of its use in nutritional aims. The healthy properties of oat are caused by presence in its composition of a number of biologically active compounds, vitamins, minerals, dietary fibers (in particular β-glucans) which play an important role in the prevention of many chronic diseases – diabetes, coronary heart disease, cancer, etc. In this study the effect of oatmeal flour and palm oil on the rheological and physicochemical parameters of the dough and the quality characteristics of oatmeal cookies has been examined. The advantages and disadvantages of using palm oil in the production of flour confectionery products and its impact on the safety of oatmeal cookies during storage, in particular the risk of oxidative damage, have been analyzed. Some methods for optimizing the technology of oatmeal cookies, providing finished products of stable quality have been proposed and implemented. The results of the product research indicate that the quality of the biscuit prototypes remains virtually unchanged in terms of organoleptic, physicochemical and microbiological indicators and, by the end of the storage period, complies with the regulated requirements. The implementation of the proposed techniques will improve the competitiveness of the enterprise by reducing the output of non-conforming products and, as a result, increasing consumer confidence. The obtained results are aimed at product differentiation based on technological superiority and high quality of finished products. The work has been performed in the laboratory of flour confectionery products of Scientific Research Institute of the Confectionery Industry, industrial designs have been obtained at the enterprises of the industry.
