The article provides a review of domestic patent information on the effectiveness of using modern probiotic feed additives in pig farming practice. The inclusion of probiotic feed additives in the diets of pigs is aimed at excluding pathogenic and opportunistic microflora from the intestinal microbiocenosis, increasing the productive action of feed and intensifying metabolic and immune processes in the organism. The introduction of probiotic feed additives into the diet of pregnant sow and suckling pigs, as well as weaned piglets, allows achieving high indicators for the safety and productivity of young animals, which is very important for the cost-effective development of production. The ability of probiotic feed additives to normalize the microflora of the gastrointestinal tract of newborn piglets provides increased resistance to mass gastrointestinal diseases, as well as increasing the safety and viability of piglets. Thus, probiotic feed additives are an important component of the modern diet of farm animals at all stages of their development. At the same time, the most popular and effective for modern pig farming are multicomponent probiotic feed additives that contain a complex of probiotic cultures with different biological effects on the organism, sorbents that often act as prebiotics, enzyme preparations and other biologically active substances that provide a positive multifunctional effect on the organism of farm animals
The article analyzes the patented in different countries
methods of using of the ionizing radiation in processes
of storing and processing of plant materials.
Description of nature of the radioactive treatment and
the ionizing radiation is given; examples of possible
sources of the ionizing radiation are listed. Advantages
and disadvantages of the radioactive treatment are
shown. The patent search in databases of the WIPO
was carried out. Patents, registered in countries like
Korea, China, Japan, etc., were analyzed. Methods,
realization of which allows sterilizing of material and
increasing its storing period, and also improving its
processing, were systematized. The carried out survey
of the patent documentation revealed, that at the
present time there is quite a number of methods of
using of the ionizing radiation in storing and processing
of plant materials, which can be explained by the fact,
that irradiation allows to solve quite effectively a
number of important tasks, such as sterilizing the
material and modifying chemical substances in its
content. In the article it is also shown, that,
nevertheless, issues of safety and quality of irradiated
products have not yet been fully resolved. In the end,
the conclusion was made about the relevance of further research in this field
To determine the mass fraction of linolenic acid in flax
seed oil the authors developed a rapid method based on
the pulse method of nuclear magnetic resonance with
the use of NMR analyzers low resolution. This method
has some significant advantages compared with the
known method on the basis of chromatographic
method for the determination of the mass fraction of
linolenic acid in the oil extracted from the seeds of
flax, namely, does not require additional sample
preparation (extracting oil by solvent), eliminates the
use of toxic chemicals, requires a much lower
investment of time to conduct a single analysis, highly
automated, and eliminates the influence of human
factor on the research results. The method is based on
the revealed correlation between the weighted average
time spin-spin relaxation of protons contained in the
triacylglycerols of the oil of the flax seed, and a mass
fraction of linolenic acid in the seed oil at a
temperature of 23ºc. In article results of research of
influence of temperature on the weighted average time
spin-spin relaxation of protons contained in the flax
seed oil. Installed directly proportional linear
relationship between the temperature of flax seeds and
measured the average time spin-spin relaxation of
protons oil contained in the flax seeds with the correlation coefficient is 0,930, the temperature change
of the sample of seeds at 1 ° C leads to the change of
the coefficient is 0.011 kt. The developed
methodaccuracy in the temperature range from 20 to
26 ºC
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 analyzes the ways of ensuring a stable
quality of vegetable raw materials in the process of
storage and use of biopreparations patented in Russia
and abroad. The search was conducted in the period
from 1995 to 2015 on the databases of the patent
agencies of the Russian Federation, the United States,
Japan and the European Patent Organization. We have
systematized the patented methods, the
implementation of which can increase the shelf life of
vegetable raw materials. The study led to the
conclusion of the usefulness of developing innovative
ways of ensuring a stable quality of vegetable raw
materials in the process of storage using
biopreparations
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
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
In recent decades, Russia has increased the demand for
high oleic sunflower oil and, consequently, for the raw
material from which it is derived – high oleic sunflower
seeds. Currently existing methods of control of mass
fraction of oleic acid in the seed oil of sunflower, have
significant drawbacks, due to which sharply raises the
question of the development of the Express methods of
control of mass fraction of oleic acid. The study presents
the results of determining the mass fraction of oleic acid
in the oil of sunflower seeds, obtained by known
methods (GC and ri), and developed a method based on
NMR. The developed method of determining the mass
fraction of oleic acid in sunflower seed oil has a number
of advantages compared with the known: is not
destructive (does not require the extraction of oil from
seeds), does not require special sample preparation
excludes the use of toxic chemicals, the analysis duration is 5 minutes, ensuring high representativeness of the
sample, and the simplicity and automation of the analysis
process reduces the requirements for qualifications of
laboratory personnel. The developed method of
determining the mass fraction of oleic acid in the oil of
sunflower seeds can be carried out simultaneously with
the determination of oil and moisture content of seeds on
commercially available analyzers, but I hope it 1006М,
which is currently applied at more than 250 companies of
oil and fat industry
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
There were presented comparative analysis’ results of
criteria rice quality used in Russian and international
standards. Also there were shown summarized
statistical analysis’ results of rice quality that was
processed in 2013-2016 on rice mill plant at
“Krasnodarzernoprodukt” Company. The purpose of
research was to find factors that had influence on
combining rice bulk effectiveness on specialized
elevator. It was found that diapason of rice moisture
content was quite small. Red rice content was ranging
from 1.08 to 5.10 % with confidence interval of 1.98-
2.56 % that is evidence of small amounts of rice bulks
with extreme high or low red rice content. Broken rice
content varied in the wide range from 3.43 to 9.26 %
with confidence interval from 5.84 to 7.26 % that
shows necessity in length grading procedure applying
for broken kernels removing at the elevator unit.
Grain impurities content exceeded basic norm in 3-4
times that is a sign of low efficiency in the process of
separation. During the treatment of rice bulks
combined at the grain cleaning unit of rice plant
broken rice cereals output varied in wide range from 3
to 9 % during single shift that is seems to be connected
with kernels cracking increasing and rice moisture
decreasing. Moreover, rice bran output also varied in a
wide diapason from 10.2 to 17.0 % that could be
explained by big swing in rice moisture, glassy texture
and cracking of rice grains. According to our research
it was investigated that current rice quality control system that is a base instrument of rice bulks forming
for further processing is not quite efficient and as a
result there should be created and implemented new
methods and technical devices for quick and proper
grain control that could assure stable technological
regimes at different stages of rice treatment process
and that would provide the best quality and the biggest
output of rice cereals
