Description
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

Description
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

Description
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

THE STUDY OF THE EFFECTS OF RICE QUALITY ON THE EFFICIENCY OF ITS PROCESSING
DescriptionThere 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

Description
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

DEVELOPMENT OF ECOLOGICALLY SAFE EXPRESS-METHOD FOR QUALITY EVALUATION OF SOYBEAN LECITHINS
DescriptionThe article presents data, on the basis of which we have concluded that the oil and phospholipids contained in soy lecithins, the degree of unsaturation of fatty acids differ significantly from oil and phospholipids contained in sunflower lecithins, with differences in the degree of unsaturation of fatty acids of oil and phospholipids contained in sunflower and soy lecithins, leads to differences in the content of resonating protons, and, consequently, the level of amplitude values of NMR signals of protons of the investigated lecithins. It is established that the values of the amplitudes of the NMR signals of protons of each of the four components of sunflower lecithins differ from the values of the amplitudes of the NMR signals of protons the component of soy lecithins, which confirms the differences in the composition and content of fatty acids lecithins studied. Considering quantitative characteristic of mass fraction of substances insoluble in acetone, i.e. phospholipids, is the sum of the amplitudes of the NMR signals of protons of the third (A3) and fourth (A4) component, was built the graphical dependence of the mass fraction of substances insoluble in acetone, from the value of (A3+A4)/ASIS, % which is described by the equation (correlation coefficient R2 =0,9911) of the following form: y=0,8177x +2.52. Based on these data, we have developed a rapid method of determining the mass fraction of substances insoluble in acetone, soy lecithin, eliminating the use of toxic organic solvents, is environmentally safe, which is protected by RF patent for the invention

Description
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
