Description
The article presents the results of the research of the influence of preliminary treatment of garden beet roots with electromagnetic fields of extremely low frequency on the loss of dry and biologically active substances, such as vitamin C and P-active substances, in the process of long term storage. Garden beet roots of Bordo 237 variety were the objects of research. The objects of research were stored for 7 months at a temperature of 0…+1° С and relative humidity of 90 %. Sampling was carried out every month during the entire storage period. The treatment with electromagnetic fields of extremely low frequency was carried out using an experimental setup of our own assembly. As a result of the conducted research it is established, that the treatment of garden beet roots of Bordo 237 variety with electromagnetic fields of extremely low frequency before dispatching into storage allows to decrease the losses of dry substances by 4,1 % by the end of the 7 months storage period, and also to decrease the losses of vitamin C by 14,8 % and P-active substances by 15,1 %. The data obtained can be used to develop new or improve existing technologies of garden beet roots storing

Description
Technologies of fruits storing known at the present time, solving actual problems – slowing down biochemical processes, inhibiting ethylene synthesis, do not provide fully the preservation of quality of fruits due to not taking into consideration the peculiarities of microflora of fruits and microbiological processes, taking place during storage. Purpose of the research: investigation of influence of complex treatment of fruits with electromagnetic fields of extremely low frequency (ELF EMF) and the biopreparation “Vitaplan” on changing of losses of biologically active substances in the process of longterm storage. Objects of the research: apples of the Idared variety and pears of the Conference variety, regionalized in the Krasnodar region. Mass shares of the vitamin C and P-active substances were measured in the process of storing. ELF EMF treatment was conducted on an experimental installation. Fruits were exposed to the action of electromagnetic fields with specified parameters. Complex treatment of fruits (apples and pears) with ELF EMF and the biopreparation “Vitaplan” before dispatching for storage allows preserving the biologically active substances – the vitamin C and P-active substances – to the maximum degree. Synergetic effect, appearing due to the complex action of electromagnetic field and the bio-preparation, allows decreasing the processing time in the electromagnetic field
