Physical, chemical and organoleptic characteristics of plant milk, which is used in hotel and restaurant complexes

Abstract

The article highlights the current state of the production of dairy and vegetable food products. The results of studies of organoleptic and physical, chemical indicators of the quality of various herbal drinks: coconut, almond and oat, are presented, as well as an analysis and comparison with cow's milk, which is used in hotel and restaurant complexes in Bela Tserkva. For assessing the quality according to the organoleptic characteristics of the beverages, the following were examined: appearance, color, smell, taste and consistency. It was found that according to these indicators, herbal drinks comply with the regulatory documentation for these products. When assessing the quality by physical and chemical indicators, the mass fraction of fat, dry matter, titratable and active acidity, and density were established. The titratable acidity of milk-like drinks was within the normal range and did not exceed 10 ⁰T. The mass fraction of fat in coconut milk was 1.2 %, almond-rice milk – 1.3 % and oat milk – 2.4 %. Mass fraction of coconut milk solids was 7.6%, almond-rice 10.5% and oat milk 11.4%. The density of all types of herbal drinks was in the range of 1005–1015 kg/m3. The indicators of the quality of cow's milk, which is used in hotel and restaurant complexes, have been investigated in a comparative form. In terms of organoleptic indicators, the quality of cow's milk corresponds to the normative documentation. The fat mass fraction of cow's milk was 2.5 %, the mass fraction of solids was 12.5%, the titratable acidity was at the level of 18 ⁰T, the active acidity pH was 6.6, and the density was 1028 kg/m3. Analysis of various types of vegetable and cow's milk, which are used in hotel and restaurant complexes in the city of Bela Tserkva, in terms of physicochemical and organoleptic quality indicators, allows us to consider herbal drinks as substitutes for traditional products capable of providing the human body with essential nutritional factors.
