Champignons stability comparative evaluation by the "texture" indicator after processing with UV radiation in the range A and C

The purpose of the presented studies was: to carry out a comparative assessment of the storage capacity in terms of the "texture" of Agaricus bisporus champignons after treatment with ultraviolet radiation in the A and C ranges during refrigerated storage. To achieve this goal, it was envisaged to solve the following tasks: packing mushrooms and processing them with UV radiation at the VNIITEK experimental setup in the A and C ranges (with a power flux density of 2.7‧103 and 6.90‧103 J/s • m², respectively) with doses 160, 320, 480, 640, 800 J/m2 with subsequent refrigerated storage at a temperature of 4 ± 2 °C and a relative humidity of 90–95 %; development of mathematical dependences of the response in terms of the "texture" indicator for the processing; determination of optimal modes of ultraviolet irradiation, contributing to a significant increase in storage capacity in terms of "texture"; comparative assessment of the influence of the type of UV radiation on the dynamics of the target indicator. The optimal modes of treatment of champignons with ultraviolet radiation, which make it possible to increase the storage capacity in terms of texture by more than 30 %, in the C range are doses from 477 to 684 J/m2, in the A range from 556 to 800 J/m2. At the same time, the extremum is reached for the C range with treatment with a dose of 684 J/m2, for the A range – 800 J/m2. Thus, the studies have shown that the most effective treatment of champignons with UV radiation in the C range, which led to an increase in storage capacity in 2.21 times, while UV treatment in the A range is 1.4 times relative to the control.
