    The polycomponent acidifiers “Optimal 1” and “Optimal 2” were elaborated at the National University of food technologies (Kyiv city, Ukraine) for intensifying the technology of rye-wheat bread and prolongation of its freshness.The composition of acidifiers includes the enzymatic preparations (EP) Glusim 10000 Mono (glucose oxidase) that favors the improvement of structural-mechanical properties of dough, EP Pentopan 500 BG (mixture of pentosanase and hemilcellulase) that favors the modification of non-starched polysaccharides and provides elastic crumb. For providing the proper dough acidity and intensification of the process of dough fermentation, the acidifier composition is added with citeric acid and dry milk serum (DMS), and for improving organoleptic parameters – with rye fermented malt (RFM). For increasing dough water-absorbing ability and keeping products\u27 freshness in the process of storage, guar gum is added.The optimal dosage of PCA “Optimal 1” and “Optimal 2” in the recipe of rye-wheat bread is 2 % to the flour mass.There are considered technological aspects of acidifiers use. There are considered processes, connected with stalling, loss of organoleptic and physical-chemical parameters of the bread quality at storage. The positive effect of acidifiers on the parameters of crumbling and swelling of bread crumb at the accelerated technology of its preparation. It was established, that the use of acidifiers favors the deceleration of rye-wheat bread staling. There was obtained the positive influence of acidifiers on preserving smell and taste of ready products. The obtained results prove the expedience of using the elaborated polycomponent acidifiers “Optimal 1” and “Optimal 2” in the technology of rye-wheat bread at its accelerated preparation. The use of the elaborated acidifiers favors the shortening of the technological process of rye-wheat bread production in 2,5-3 times and provide freshness, taste and smell preservation in ready products

    The materials of the article are studies that are conducted with the aim of expanding the use of non-traditional raw materials for functional purposes in the technology of bakery products. Research is conducted to determine the effect of spiciness cinnamon on the quality of semi-finished products and finished bakery products from wheat flour enriched with flax seeds oil meal.To improve the quality of wheat bread, enriched with flax seeds oil meal, and expand the assortment of bakery products with health properties, the authors propose to use spice cinnamon in the formula of wheat bread in an amount of up to 2 % of the weight of flour. The taste and aroma of these products is characteristic of wheat bread with a pleasant cinnamon flavor. Dosage of cinnamon to 4 % of the flour mass also provides good consumer characteristics of products, however, more pronounced flavor and flavor of cinnamon can limit the circle of consumers of such products. The use of 6 % of cinnamon in the recipe of products leads to a significant deterioration in the volume of products and provides them with too intense flavor. Determination of the content of bisulphite-binding substances in the crumb and crust of products is confirmed by improvements in the fragrance of products with the addition of cinnamon.It has been established that the cinnamon in dough leads to an increase in the elastic properties of gluten, and the more, the more it is added. Along with this, it is noted that cinnamon leads to a decrease in the fermentation intensity of the dough. This is probably due to the active antibacterial properties of cinnamon, which suppress the yeast fermentation activity. These factors and cause the deterioration of the volume of finished products in the case of dosing cinnamon in an amount of 4 % or more.It has been proved that on the indicators of crumbling and deformation of the crumb, products with added cinnamon retain their freshness similarly to the control one. However, it is noted that the introduction of cinnamon reduces the amount of mold of microflora in products

    The paper reports a study into the influence of electrospark dispersion of current-conductive granules of magnesium and manganese in the environment of milk whey on the process of its fermentation in the technology of making soft thermo-acid cheeses the type of "Adyheyskyy".The object of this study was milk whey, obtained from the thermo-acid settling of cheeses. To prepare the coagulant, it was treated in an electric discharge chamber with a current-conductive layer of magnesium or/and manganese granules manganese over 30...120 s.It has been established that the result of such a treatment of milk whey is the increased magnesium content, by 1.8 to 4 times on average, and the increased manganese content, by 1.5 to 3.8 times on average, depending on the treatment duration.It has been proven that it was characteristic, of all the examined samples, to demonstrate a natural growth of titrated acidity during fermentation. However, the samples enriched with mineral elements following the electrospark treatment over 30...60 s have shown a more intensive growth in titrated acidity. Similar results were obtained when using milk whey from cottage cheese. Although at the initial stages of fermentation (0...6 hours) the increase in acidity was somewhat slower, which has an objective explanation related to the effect of enhanced acidity of the starting whey (50...60 °T) on lactobacilli.It was established that the production cycle is significantly reduced in case of using the proposed technology of acidic whey-coagulant for making thermo-acid cheeses.There is also an increase in the utilization coefficient of technological equipment and its resources. A given technology does not require significant areas for the introduction of an innovative electro-physical technique, and, instead, given the reduced fermentation time, it contributes to reducing the number of containers involved in the preparation of coagulant.It has been established that the use of acidic whey, produced from raw materials enriched with magnesium and manganese, in the technology of thermo-acid cheese contributes to its enrichment with valuable mineral elements. It also provides for a more complete use of the protein potential of milk and, consequently, increases the thermo-acid cheese yield by 1.8...6.5

    The object of research in this work is a baked product enriched with a mixture of sprouted grains, ground cinnamon, apple pectin, dry wheat gluten, ascorbic acid. Pastries occupy an important place in the production and sale of food products and have a high calorie content. To reduce the energy value of pastry products, it is proposed to replace wheat flour in the recipe with a mixture of germinated grains of wheat, oats, barley and corn. In this work, the properties of such mixtures were studied using the example of a mixture of the «CHOICE» company (Ukraine). The mixture of germinated grains of cereals of wheat, oats, barley and corn of this company is rich in dietary fiber, nonessential and irreplaceable amino acids, microelements and macroelements, vitamins. It has been established that a rational substitution of premium wheat flour for a mixture of germinated grains in the recipe for pastry products is 50 %. Due to the germination process, a large amount of amylolytic and proteolytic enzymes accumulates in cereals, which impair the structural and mechanical properties of the crumb of pastry products, as a result of which the crumb of the product becomes sticky and wrinkled. The work was aimed at developing a multicomponent mixture to improve the quality of pastry products, the formulation of which includes a mixture of germinated grains. A «Solodok» multicomponent mixture has been developed, which has a positive effect on the organoleptic and structural-mechanical properties of the product crumb. The mixture contains safe food additives and ingredients: ground cinnamon, dry wheat gluten, apple pectin, ascorbic acid. It has been established that the introduction of the «Solodok» multicomponent mixture into the dough leads to the replacement of the fermentation process with the stage of sedimentation. The use of a multicomponent mixture leads to an improvement in the organoleptic characteristics of rich products, an increase in the specific volume of products, and an improvement in the development of the porosity of products. Adding a mixture of sprouted grains and a «Solodok» multicomponent mixture leads to a change in the traditional taste, the products acquire a pleasant aftertaste of sprouted cereals and cinnamon. The use of a mixture of germinated grains and a «Solodok» multicomponent mixture in the recipe for pastry products leads to a decrease in the energy value of pastry products in comparison with the control
