The subject of research is standardization as one of the forms of technical regulation in the food industry of Ukraine, in particular in the production of milk and milk products, meat and meat products, determination of safety and quality parameters of the specified food raw materials and finished products made from those, as well as installations and equipment for the food industry. The purpose of the study is to analyze the state of standardization in the production of dairy and meat products, highlight the existing problems and possible ways to solve them, as well as outline the role that the Technical Committee for Standardization 140 “Milk, meat and products of their processing” should play in these processes. Methods. During the research, a systematic approach was used to research factual materials, in particular scientific and scientific-practical literature, regulatory legal acts, regulatory documents and the like, abstract-logical approach to the synthesis of research results and the formulation of conclusions. The results of the study. National standards of Ukraine DSTU is the base of the technical regulation in relation to food products and methods of their control. The above also applies to standardization in the field of milk and meat products, which is within the competence scope of the Technical Committee for Standardization 140 “Milk, meat and products of their processing”. Technical Committee 140 carries out significant work to develop new and update existing national standards in accordance with its area of competence, in particular, it has significant success in harmonizing international and European standards. As of January 15, 2021, according to the classification code 67.100 (Milk and milk products) out of 203 standards of the nationwide force, 103 standards (50.7%) were developed by harmonizing the relevant international standards EN, ISO, etc. According to the classification code 67.120 (Meat, meat products and other animal products) – 202 units, 26 units and 14.1 %, respectively, according to the classification code 67.260 (Installations and equipment for the food industry) – 99 units, 86 units and 86.9%, respectively. The issue of attracting extra-budgetary funds for the harmonization of international standards and the implementation of the entire range of works on standardization is urgent. The issue of proper regulatory support for the production and operation of specialized technological equipment for food and processing industry enterprises is relevant, for which it is advisable to combine the domestic traditions of standardization with the priorities of safety and hygiene of machines, as well as ecology, which are in force in international practice. Scope of research results. The results of the studies performed will be used in the field of technical regulation, in particular, national standardization, of milk and milk products, meat and meat products, determination of safety and quality indicators of the specified food raw materials and finished products made from it, as well as installations and equipment for the food industry.
The composition and properties of cream with fat levels from 30% to 70% were investigated. It has been established that the decrease of fat level and, accordingly, the increase of plasma level in the cream leads to significant changes in the physicochemical parameters of the fat emulsion. Accordingly, the production of low-fat dairy products requires adjustment of the cream properties. It has been shown that using different doses of structure stabilizers: QNA colloid as a consistency stabilizer in the amount of from 1 to 2% and the Dimodan emulsifier U/G – from 0 to 1 % (Danisco, Denmark) changes the physicochemical properties (effective viscosity, sedimentation stability) and organoleptic properties (consistency, taste) of cream with fat level 40%. It has been conducted mathematical modeling, aimed to calculate dosing for improving the properties of milk-fat emulsions, structure formation and further ensuring of the necessary consistency of cream pastes. Optimal doses of colloid QNA as a consistency stabilizer and a U/G Dimodan emulsifier have been determined. It has been established that their content should be 1,0% and 0,5%, relatively, for pastes with a fat level of 40%. The effectiveness of the joint action of consistency stabilizers and emulsifiers in obtaining milk-fat emulsions were defined by the level of effective viscosity. Moreover, the use of the emulsifier had less effect on the effective viscosity of the milk-fat emulsions. It has been found that using the structure stabilizers could improve the formation of low-fat products and the formation of the desired paste-like consistency of high-fat cream with a fat level of 70%. Thus, it is possible to adjust the composition and properties of raw material as a basis for milk-fat emulsions by optimizing the ratio of structure stabilizers. Comparative evaluation of the physicochemical properties of milk-fat emulsions and high-fat cream makes it possible to predict their potential for conversion into a creamy paste with a given consistency.
