A methodology for assessing the organoleptic value of plant objects subject to cold storage has been developed. Preliminary studies revealed the degree of cryoscopic denaturation of free and bound water in frozen meat, fish raw materials, and grapes. No such work has been carried out in other fruits, vegetables and berries. This study shows the possibility of ensuring high consumer quality of vegetable raw materials during its cold storage through the use of acoustic freezing (AEF). The effect of acoustic freezing and shock freezing on the consumer quality of plant raw materials is compared. A method of organoleptic assessment of the quality of plant products stored in cryoscopic conditions has been developed. An examination of the consumer quality of plant objects (raspberries, blackberry raspberries, garden strawberries (strawberries), blueberries, zucchini, carrots and figs) was carried out on the basis of the developed methodology of organoleptic assessment. It is established that when storing plant raw materials under acoustic freezing conditions, its consumer quality remains high and can be classified as �Premium� and �Basic�. It is revealed that the storage of plant raw materials under the conditions of an innovative method of acoustic freezing, which prevents the crystallization of free and bound intracellular water, in contrast to shock freezing, allows to significantly preserve its consumer quality. The developed method of refrigerating plant objects under acoustic freezing conditions allows plant raw materials to be classified into various quality categories after defrosting.
