Long-term storage of fruits can be achieved by means
of decreasing microbial contamination of their surface
as a result of fruits pre-treatment by biopreparations
before dispatching for storage. In the current study
patterns of influence of fruits pre-treatment with the
“Ekstrasol” biopreparation in a number of
concentrations of bioagent on the microbial
contamination of their surface during storage are
revealed. The “Ekstrasol” preparation is a biofungicide,
containing the Ch-13 strain of Bacillus subtilis bacteria
and their metabolites. As research objects there were
chosen apples of a zoned in the Krasnodar region
variety called Idared and pears of a zoned in the
Krasnodar region variety called Conference, harvested
in 2016. The apples and the pears were stored over a
period of 6 months in the low temperature conditions.
Samples were withdrawn every month over the period
of storing. The species composition and quantity of the
most prevalent microorganisms, potentially causing the
spoilage of apples and pears during storing, were
identified. The optimal concentration of the bioagent,
which provides the maximal decreasing of microbial
contamination of fruits’ (apples and pears) surface, is
established – 106
CFU/g, dosage of solution – 1 ml per 100 g of fruit
Fruits are an important part of the diet of humans and
many animals. In case of an improperly organized
process of storing of fruits, the loss of mass and
decrease of quality can be substantial. This makes
relevant the research, aimed at enhancing existing and
developing new technologies of fruits storing. In this
article, the results of the investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (EMF ELF) and а biopreparation
on the change of microbial contamination
of their surface and on the loss of mass in the process
of long-term storage are revealed. Apples of the Idared
variety and pears of the Conference variety were the
objects of research. The change of microbial
contamination of the surface of fruits, undergone a few
types of pre-treatment (EMP ELF, bio-preparation
“Vitaplan”, complex treatment “EMP ELF + the biopreparation”
and no special treatment), after storing during 7 months in case of pears and 8 months in case
of apples is shown in the article. It was found, that the
greatest decrease of content of microorganisms on the
fruits’ surface is achieved as a result of the complex
treatment, combining the treatment with EMP ELF and
an aqueous solution of the “Vitaplan” bio-preparation.
The effective parameters of such a treatment for apples
and pears are represented
