Long-term storage of fruits can be achieved by means
of their special preparation by pre-treatment before
storage by electromagnetic fields of extremely low
frequency (ELF EMF). In the current study patterns of
influence of ELF EMF pre-treatment of fruits on the
effectiveness of reducing microbial contamination
during storage for the development of effective
technological modes of preparation of fruits before
storage are revealed. Qualitative and quantitative
characteristics of microbial contamination of the fruits’
surface were studied. Effective modes of fruits (apples
and pears) treatment by ELF EMF were established -
for apples: frequency - 22 Hz, current - 10 A for 40
minutes, and for pears: frequency - 26 Hz, current - 5 A
for 50 minutes, allowing to reduce to the maximum
extent the microbial contamination of their surface, and
also to reduce the loss of their weight from microbial
spoilage during storage. The terms of storage of
processed by ELF EMF fruits under refrigeration were
established - for apple varieties Idared and Golden
Delicious - within 8 months, for pear variety
Conference - for 7 months
An analysis of patented in Russia and abroad methods for
providing preservation of plant products, particularly apples
and pears, was carried out in the article. The patent search
was made for the period from 1995 to 2015 in the databases
of patent offices of the United States of America, Japan and
European patent organization. The patented methods,
realization of which allows increasing of storage life of
agricultural products by means of using different kinds of
electromagnetic radiation, regulating the content of gaseous
medium in the storage, treating with chemical substances,
inhibiting the microbiological processes, creating hermetic
storing conditions, were systematized.
The realized research allowed drawing a conclusion on the
relevance of work in the field of search for new methods for
providing stable quality of fruits in the process of storing,
particularly with the use of electromagnetic fields of very
low frequency
The article presents data characterizing the
composition of macro and micronutrients from
secondary resources of pumpkin processing – pumpkin
pomace. We have found that extracts of pumpkin are
valuable raw materials for the production of food
additives, as they contain proteins, dietary fiber,
including pectin and protopectin, minerals, as well as
such biologically active substances as vitamin C, β-
carotene and P-active substances using nuclear
magnetic relaxation, it is shown that pretreatment of
pomace pumpkin in the microwave electromagnetic
field of certain parameters before IR drying allows to
transfer part of the bound moisture free moisture, that
allows to intensify the subsequent process IR drying.
We have developed an innovative technology of
production of food supplements from pumpkin
extracts, which is protected by Russian patent for the
invention and having the “know-how” status. The
article presents data describing the organoleptic and
physical and chemical indicators of quality nutritional
supplements, formulated according to the developed
technological regimes
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
The article provides experimental data, which help to
substantiate the effectiveness and feasibility of
application of plant resources, produced by the rubbing
of the pears in the production process of puree as raw
material for the production of secondary food additive.
For the first time, with the use of pulsed NMR it is
established that processing of secondary resources of
pears processing in UHF EMF influence on the
redistribution of bound and free moisture, i.e., the
maximum transition was for linked moisture to free
moisture, noted in the processing of secondary
resources in UHF EMF with the rate of heating
(increase in temperature) 0,4 °С/s to a temperature of
60 °С. It is established that such processing of
secondary resources of processing of pears allows to
increase the average speed of the subsequent IR-drying
and reduce the time IR drying in 2 times in comparison
with IR-drying of control sample (without
pretreatment in UHF EMF). Pre-treatment of
secondary resources of processing of pears to UHF
EMF for the identified modes allows for their
subsequent IR-drying to reduce the loss of vitamin C,
23.9% and P-active substances – by 20.6% compared
with the control sample. We have developed technological modes of production of food additives
from secondary resources of processing of pears,
providing maximum preservation in its composition of
thermolabile biologically active substances – vitamin
C and P-active substances. On the basis of these
studies, there was developed a set of technical
documentation, including TU 10.39.25-423-
040801346-2016 "Food additive. Pear Powder" and a
technological instruction for the production of food
additives
The article lists the characteristic and scrutinizes features
of modern topinambur varieties. Data, characterizing

Based on the complex of studies carried out, the
formulation of wafers (wafer sheets) enriched with
food additives "Powder from the tubers of Jerusalem
artichoke" and skimmed sunflower lecithin was
developed, as well as the formulation of fat filling
enriched with a complex of food additives "Powder
from tubers of Jerusalem artichoke", "Powder from
hips" And low-fat sunflower lecithin. A recipe was
developed and an assessment of the organoleptic and
physicochemical parameters of enriched waffles with a
filling was made. The storage period, ensuring safety
and maximum preservation of consumer properties,
was established. The study of the nutritional value of
the developed waffles with filling allowed to establish
that in comparison with the control sample they
contain inulin and vitamin C, while the degree of
satisfaction of the daily demand for these nutrients
with consumption of 100 g of the developed product is
16.46 and 24.65% respectively. In addition, the
developed products, in comparison with the control
sample, are characterized by an increased content of
dietary fiber, potassium, magnesium, phosphorus, iron,
vitamins B1, B2 and B6
The article presents results of research of quality,
safety and content of biologically active substances of
food red beet roots of Bordo 237 variety, grown in the
Krasnodar region in 2014. On the basis of the research
carried out it was established, that there are
carbohydrates, proteins, organic acids and mineral
substances in the food red beet roots of Bordo 237
variety. Food red beet roots are a source of dietary
fibers (pectin, protopectin, hemicelluloses and
cellulose), possessing antitoxic, antioxidant, radiation
protective, cholesterol-lowering and lipid correcting
qualities, and also a source of vitamins C, B9 (folic
acid) and P-active substances, possessing antioxidant
properties. Due to high content in food red beet of a
complex of microelements – iron, zinc, manganese and
copper, and a complex of macro elements – potassium
and magnesium, it can be recommended for
prophylaxis and treatment of hypertension,
atherosclerosis and other diseases of heart and vascular
system, and for prophylaxis of iron-deficiency anemia.
Thus, the research of quality, safety and content of
biologically active substances showed that food red
beet roots of Bordo 237 variety are a high quality component ingredient for creation of food products of
specialized and functional purpose
