Abstract

The article is devoted to the assessment of the quality of canned dairy products demanded by consumers and occupying a certain place in the consumer basket. The assortment of canned dairy is wide and varied, and therefore, the products must be attractive not only in terms of the price category, but also meet the quality requirements and consumer appraisal. Canned milk condensed with sugar from various manufacturers, presented on the consumer market in Kemerovo, were selected as samples. When performing the research, organoleptic and qualimetric methods of analysis were used. Determination of the state of packaging and labeling was carried out in accordance with the requirements of the current regulatory documents TR CU 022/2011, TR CU 005/2011. The quality indicators of the samples were determined in accordance with GOST 31688-2012 and TR CU 033/2013. Sensory assessment of the samples was carried out according to the developed 25-point scale. The paper presents the results of evaluating the consumer properties of the selected objects, notes the advantages and disadvantages of packaging and labeling of objects, presents the results of ranking canned milk by the method of descriptor-profile analysis, when the objects of examination are presented in order of decreasing sensory characteristics. The final determination of the degree of preference by the tasters based on the results of the sensory evaluation of the samples was considered. We revealed the similarities and differences between the samples in accordance with the assigned points. Consumer properties were characterized by ergonomic and aesthetic indicators of packaging and labeling of samples. The obtained results may be interesting for dairy processing enterprises when they are establishing a quality category and for trade organizations when they are forming an assortment of canned dairy.
