description: This work is devoted to the assessment of the consumer properties of dry building mixtures and the development of proposals for improving their quality in a retail trade enterprise. The tasks that were solved during the study: 1. Consider the factors affecting the consumer properties of the product, and determine the requirements for its quality. 2. To assess the quality of sand as a basis for dry building mixtures of different grades and samples of one enterprise, justifying the choice of samples and research methods. 3. Draw conclusions on the quality of the investigated products and the work of the enterprise on the basis of the analysis of the results of the studies of the samples. 4. Analyze the actual range of dry building mixtures of the retail trade enterprise and, based on the data on the study of consumer preferences, develop proposals for its improvement. The research was carried out on the basis of the laboratory of Sibelko Nebolchi LLC. The work uses standard and generally recognized research methods in commodity science: determination of the chemical composition, determination of particle size distribution, determination of the mass fraction of moisture. As a result, it was found that all the samples under study, despite minor deviations, meet the requirements and are suitable for use in production. Based on the analysis of the products of the retail trade enterprise, recommendations were formulated aimed at improving the quality: improving product labeling and adding new indicators, improving storage conditions taking into account the specificity of the product, improving the quality of product delivery taking into account the specificity of the product.
