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
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
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
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
The article provides an overview of Express-methods
of quality evaluation and identification of lipidcontaining
plant raw materials (oil seeds) and its
processed products (oil cakes, oilseed meals, vegetable
oils, lecithins) using pulse method of nuclear magnetic
resonance. Development of express methods of quality
evaluation and identification of lipid-containing plant
raw materials and products of its processing is a
priority, as these methods are environmentally safe and
also allow us to regulate technological conditions of
refining processes, are characterized by low error of
determination, i.e., high precision, and, in some cases,
it is only possible to use because of its non-destructive
effects on the analyzed sample. Currently, we can
distinguish the following main directions of quality
evaluation and identification of lipid-containing plant
raw materials and products of its processing on the
basis of the pulse method of nuclear magnetic
resonance: assessment of quality and identification of
oilseeds (sunflower, canola, flax, soybeans);
evaluation of quality of products of processing of oil raw materials (cake and meal); the quality evaluation
and identification of vegetable oils; assessment of the
quality of the lecithins obtained from vegetable oils.
The methods of quality evaluation and identification of
lipid-containing plant raw materials and its products
are patented and have several advantages: short time (5
minutes) spent on the implementation of the single
analysis; eliminates the use of toxic chemicals; does
not require special training of laboratory personnel;
non-destructive character, which is especially
important for oilseeds from the point of view of
breeding work. On the basis of the conducted survey
we can conclude that the pulse method of nuclear
magnetic resonance has found wide application for
assessment of quality and identification of lipidcontaining
plant raw materials and products of its
processing, through rapid capabilities, high accuracy
and ease of analysis
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
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
