There was grounded the expedience of using "Amaranth" cryoadditive in the technology of processed cheeses. "Amaranth" cryoadditive contains necessary vitamins and microelements of the natural origin. The use of "Amaranth" cryopowder in the processed cheeses technology allows to enrich them with vitamins, mineral substances and food fibers. The main factors of introducing "Amaranth" cryoadditive were: the normative organoleptic estimation of a product and its daily need. Introduction of "Amaranth" cryopowder in cheese masses results in the energetic value growth along with the treating-prophylactic effect. The complicated complex of chemical and biochemical compounds, included in the composition of "Amaranth" cryopowder, allows to relate it to products with the wide spectrum of treating-prophylactic and radio-protective properties. Organoleptic characteristics of processed cheeses with cryopowder "Amaranth" testified that experimental samples of cheese keep the tender, elastic and resilient consistence. They have the specific original taste and smell (of cream butter). They had the homogenous picture on the cut, paste of the light-yellow or yellow color with separate dots of amaranth (black-red color). The surface of experimental samples was clean, shiny, correspondent to standards. Experimental samples had the pleasant commodity look. Processed cheese, produced using "Amaranth" cryopowder, combines in itself traditional consumption properties with technological possibilities of functional-technological ingredients of the vegetable origin. The offered products widen the assortment of milk products of the treating-prophylactic direction.
An important task for food processing enterprises is the search, development and implementation of cost-effective, technically advanced and environmentally friendly technologies for the food industry. Recently, a promising direction in the production of food products – treatment and prevention products containing a variety of supplements, including and vegetable. Medicinal properties of food herbs are due to the presence of biologically active substances, including various vitamins, micro-, macronutrients and various enzymes. The purpose of the experiments was to study the optimal ratios of prescription components for the production of processed cheese “Ukrainian” with the use of vegetable spices, study the possibility and methods of using them in the production process of a new type of processed cheese in the enterprise, development of optimal doses of “Ukrainska kuchnia”. According to the research plan, the experiments were conducted in the central laboratory and production shops of Ivano-Frankivsk Dairy Plant, Department of Milk and Dairy Products Technology, Stepan Gzhytskyi National University of Veterinary Medicine and Biotechnologies Lviv. National species “Ukrainska kuchnia” was used for research. As evidenced by the results of the tasting evaluation of these prototypes, the best organoleptic evaluation was received by the recipe № 2 the composition of which provides (per 1000 kg of finished product): 373 kg of rennet Dutch cheese; 63.2 low-fat cheese; 30.6 cow's milk powder; 39.7 kg of peasant oil, salt solution of the ruler 102 kg; 107.2 kg of drinking water and 14.0 kg of spices “Ukrainska kuchnia” per 1000 kg of finished product. Additions to the recipe of the phytospection “Ukrainska kuchnia” led to a certain change in the organoleptics of the prototypes of the proposed salted processed cheese, of course with the acquisition of certain characteristics of the filler – spices “Ukrainska kuchnia”. All experimental samples of cheese were characterized by the same values of mass fraction of moisture – 51.7 % vs. 52 % in the prototype, salt content 2.8 % vs. 3.0 %, and the pH of experimental samples of processed cheese “Ukrainian” was respectively 5.6, which corresponds regulatory requirements. From the results of the tasting evaluation of the samples, all of them met the regulatory requirements and received quite high characteristics (28 and 29 points, respectively). In parallel, a microbiological evaluation of processed cheeses was performed. In evaluating the obtained data, both traditional products and prototypes had regulatory safety indicators. At the same time, no harmful and dangerous microflora was detected. Summarizing the above experimental data, it can be noted that the use as a recipe component for the production of processed cheese spice “Ukrainska kuchnia” based on processed cheese “Hostryi z pertsem” is appropriate, and the resulting product is biologically valuable, has proper product characteristics, safety indicators and expands the range of domestic dairy products for treatment and prevention.
The aim of the work was the study of keeping probiotic properties of sour-milk butter with inclusion of Lactobacillus acidophilus La-5 (La-5) monoculture. Flora Danica mesophile culture independently (FD); in combination with La-5 and La-5 independently were used for fermenting cream. The output consistence of culture in cream was 1×106 CFU/cm3. In autumn-winter and spring-summer period of the year four butter groups were prepared, they differed by temperature of cream fermentation: I group – (30±1) ºС; II – (37±1) ºС; III – stage regimes of combination of fermentation and physical maturing; IV group – introduction of cultures into oil kernel; the output concentration – 1·108 CFU/cm3. As to the features of summer and winter periods, in summer one cream fermentation is more active that is indicated by more number of cells of both microbial cultures. The best parameters of viable cells keeping were typical to the samples at FD+La-5 use and temperature of cream fermentation (30±1) ºС. Storage life of sour-cream butter with probiotic properties is 35 days at temperature 0…-5 ºС.
