The article analyzes the proprietary methods of
processing of vegetable raw materials and secondary
resources with the use of electromagnetic fields (EMF
SHF). Analysis of the database of Rospatent World
Intellectual Property Organization led to the conclusion
that EMF SHF used in the processing of vegetable raw
materials in the following processes: drying, reduction
of microbial contamination (decontamination), juice
production and extraction. It is established that the
application of EMF SHF is the most effective in
preparation for drying a plant raw material and not
directly at the stage of drying, thus reducing the loss of
heat-labile active compound in the drying process, and
therefore obtain a finished product of higher quality
and nutritional value. The patented methods of
extraction of vegetable raw materials extraction process
performed that extracting directly EMF SHF does not
allow pre-hold inactivate enzymes contained in the raw
material and lead to undesirable oxidative and
hydrolytic processes, and hence a decrease in the yield
of extractable substances in the extract and the
deterioration of its quality . Therefore, as in the case of
drying plant material, EMF SHF can be more
effectively used in preparation for an extraction
process. Based on the analysis, it was concluded that
the relevance of developments in the field of
technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage
of their preparation for such basic processes - drying,
extraction, etc.
The article presents the results of the patent
research in the field of modern production
technologies of Inulin from plant material. It has
been established that the differences of the currently
known methods of production of inulin are
concluded in selecting raw materials pretreatment
inulin-containing modes type extractant and
extraction methods, methods of purification
inulincontaining extract and methods for producing
the final product. A significant amount of Inulin
production methods is based on use of freshly
feedstock. A number of methods have been
patented involving the extraction Inulin from plant
raw materials previously stabilized by drying. In
most of the methods, inulin extraction is carried out
at elevated temperatures with water or aqueous salt
solutions. Several technologies involve extraction
with organic solvents at low temperatures. Have
been patented several processes in which the
extraction is replaced by a separation process using
inulincontaining juice and physical and mechanical
methods. Some of the known processes provide for
the extraction process to further operations, such as
blanching vegetable raw materials, sonication,
vibration impact, processing enzymes. The most
promising direction to improve manufacturing
technology of inulin from fresh plant raw materials
is to conduct research on the use of electromagnetic
fields at microwave frequencies, the inactivating effects of which on enzyme systems is an
established fact that, in turn, would eliminate the
use of chemical agents for inactivation of oxidative
enzymes. In addition, considering that more
effective are the methods for the preparation of
inulin from freshly harvested plant material, are
relevant researches on development of innovative
technologies to prepare it for storage and its
storage, which will provide inhibition of unwanted
biochemical and microbiological processes that
occur during storage and lead to a loss of inulin
The article analyzes the existing technologies and
methods of storage of tubers of topinambur. We have
analyzed the traditional methods of storage of tubers of
topinambur - in containers, boxes or bags in storage or
in the ground clamps. Russian and foreign topinambur
tubers storage technologies in modified atmosphere,
with use of easily removable wax coating, with plant
extracts treatment, at different storage temperatures are
studied. We have also carried out analysis of scientific
and patent sources led to the conclusion that existing
technologies and methods of storing topinambur tubers,
which do not allow reducing to the maximum extent
the weight loss and the inulin hydrolysis during
storage. A reasonable conclusion was made about the
advisability of further studies in the field of innovative
technologies and methods of preparation for storage
and storage of topinambur tubers, ensuring minimal
weight loss, as well as maximum preservation in their
structure of inulin, vitamin C and other biologically
active substances during storage
The article lists the characteristic and scrutinizes features
of modern topinambur varieties. Data, characterizing
acres in crops and crop yield abroad and in Russian
Federation, are analyzed. Classification traits of
topinambur varieties, included in the state register of
selection achievements, are studied. Data on crop yield,
duration of vegetative period, composition of carbohydrate
complex, content of vitamins, macro- and microelements
are systematized. The article studies most
popular foreign topinambur varieties. The carried out
analysis of scientific sources on agrobiological properties
and chemical composition of topinambur varieties
allowed choosing varieties, which are the most promising
for industrial processing
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
The article analyzes technologies and production
methods of food and biologically active additives from
secondary plant resources developed in Russia and
abroad. We have studied a classification of secondary
resources resulting from the processing of vegetable raw
materials. It is found, that the most interesting (in terms
of macro and micronutrients) are secondary resources
resulting from the processing of fruit, vegetables and
grapes, in the manufacturing process of vegetable oil,
flour and cereals industry. It is concluded that, despite a
significant number of currently developed and
implemented technologies, the development of relevant
ones provides complex processing of vegetable raw
materials, with the release of a wide range of food and
dietary supplements, resulting in a number of
physiologically and technologically functional
properties
The article provides an analysis of currently known
technologies and methods of production of food
supplements based on vegetable raw materials. It has
been established that a great interest from the
standpoint of macro and micronutrients we have for
nutritional supplements baseв on artichoke. Our
analysis led to the conclusion that, despite the
significant number of developed and implemented
newest technologies, the development of complex
processing of vegetable raw materials to produce
dietary supplements is still relevant. Researches in the
field of enriched and functional bakery and pastry
products are actual and timely, with a special
importance in the manufacture of such products of
food additives, positively affecting the quality of
finished products, and containing a complex of
vitamins, food fibers, macro - and microelements
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
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
A selection of food additives for the enrichment of
waffle products was made. Food additive "Powder
from tubers of Jerusalem artichoke" is distinguished by
a high content of inulin - 46.21%. Low-fat sunflower
lecithin contains a significant amount of phospholipids
(98.29%). The influence of the joint application of
food additives "Powder from the tubers of Jerusalem
artichoke" and nonfat sunflower lecithin on the
technological properties of the wafer test was studied.
It is established that the introduction of the food
additive "Powder from the tubers of Jerusalem
artichoke" together with defatted sunflower lecithin,
instead of the traditional soybean, allows to reduce the
viscosity of the wafer test. When introduced into wafer
dough, the dosage of defatted sunflower lecithin can be
reduced, compared to soybean, from 0.4 to 0.2% by
weight of flour
