Factors Of Influence

We have researched the scientists' opinions on the classification of product quality control and, based on the research conducted, organized a classification using a scientifically based approach. In general, the attention of scientists is paid to factors affecting the quality of products, while issues of the quality control system and factors of influence on it are insufficiently investigated. We have identified and grouped the factors influencing the quality control system of domestic meat processing enterprises by organizational, technical and subjective features. We conducted a survey of leading specialists of the most successful representatives of the meat processing industry today in order to identify the rating of negative factors. The most important factors of influence are the serviceability of equipment, devices, working tools and measuring instruments, through which the level of its quality is measured. We investigated the typical scheme of the production process, indicating the quality control points of domestic meat processing enterprises. We have found a lack of control of the value of meat raw materials at the entrance, which does not allow calculating with suppliers of raw materials, depending on the categories to which the pork actually belongs. We recommend that quality control be performed at the slaughter section between the 4th and 5th stages of the technological stage, namely after the sting of a pig with the use of special devices that are currently absent in domestic meat processing plants. The proposed measures to improve the quality control system will provide an opportunity for a comprehensive assessment of its quality and contribute to a reduction in the cost of production, resulting in increased profitability of enterprises, which suggests the feasibility of their use for meat processing enterprises in Ukraine. The three-dimensional matrix model of quality control of products of meat processing enterprises has been developed. The advantage of this model lies in the coherence of all parameters, as well as in establishing interrelationships and interdependencies between them. It is proved that the application of the proposed multivariate matrix model of product quality control in the indicated parameters enables to evaluate the quality of the meat-processing enterprise's products, taking into account all parameters of control, namely levels of control, types of control, stages of the control process and can be used for any subject of economic activity taking into account industry specifics and specific management objectives.

Control Criteria

Усовершенствована система контроля качества коньячной продукции путем расширения перечня показателей контроля. Объектом исследований были коньяки и коньячные дистилляты, молодые и выдержанные от 1 года до 40 лет, выработанные в условиях разных географических зон стран СНГ и ЕС; опытные образцы дистиллятов на основе виноградного, яблочного и зернового сырья, образцы коньячных дистиллятов, выдержанных на дубовой клепке из древесины дуба кавказского и французского. С учетом результатов многолетних исследований обоснован выбор дополнительных показателей контроля качества коньячных дистиллятов и коньяков. Сформированы три группы критериев контроля качества: единичные летучие примесные компоненты состава, единичные экстрагируемые компоненты состава и блок расчетных критериев на основе соотношений концентраций компонентов состава. Статистическую обработку результатов исследований проводили с использованием компьютерной программы Statistica 6.0. Установлены 22 критериальных компонента состава, которые могут быть использованы в качестве единичных показателей контроля, и 8 расчетных показателей контроля качества, позволяющих подтверждать подлинность коньячной продукции и выявлять признаки фальсификации, оценивать соответствие использованного сырья заявленному наименованию и требуемым нормативам качества, обнаруживать использование запрещенных приемов на стадии переработки винограда и при проведении выдержки коньячных дистиллятов в контакте с древесиной дуба, а также нарушения в процессе дистилляции и факты внесения запрещенных добавок. The quality control system of cognac products by expanding the list of control indicators has been improved. The research materials were brandy and distillates young and mature, aged from 1 year to 40 years, developed under different geographical zones of the CIS countries and the EU; the test samples of the distillate on the basis of grape, Apple and grain raw materials, samples of cognac distillates aged on oak rivets from oak wood Caucasian and French. Taking into account the results of many years of research, the choice of additional indicators of quality control of brandy and distillates is justified. Three groups of quality control criteria: single volatile impurity components of the composition, single extractable components of the composition and a block of design criteria based on the ratio of the concentrations of the components of the composition – are formed. Statistical processing of the research results was performed using a computer program Statistica 6.0. 22 criteria components of the composition, which can be used as single indicators of control, and 8 calculated indicators of quality control, allowing to confirm the authenticity of brandy products and to identify signs of falsification, to assess the compliance of the used raw materials to the declared name and the required quality standards, to detect the use of prohibited methods at the stage of processing grapes and during the aging of distillates in contact with oak wood, as well as violations in the distillation process and the facts of introduction of prohibited additives, have been established.
