Substantiation of necessity of application of phospholipids in the production of functional foodstuffs

N.N. Cornen, S.A. Kalmanovich, T.A. Shakhrai, E.P. Viktorova

The analysis of modern scientific ideas about the role of phospholipids (FL) in ensuring the functioning of biomembranes and their regulatory function in the most important cellular processes is carried out. So, 50% of a liver, 1/3 brain isolating and protective fabrics surrounding a brain and spinal cord consist of FL. According to the recommendations of the Russian Academy of Medical Sciences, the physiological need of an adult in FL is 5–7 g/day. According to the conducted studies, in the nutritional status of the Russian population, the deficit of FL is from 50 to 80%. It is shown that the current level of knowledge about the physiological role of FL contributes to the creation and introduction of phospholipid products based on FL and phospholipid supplements on the basis of vegetable lecithins, the use of which can normalize the nutritional status. The description of phospholipid products and dietary supplements developed by scientists of the Kuban State Technological University of the Tonus series (Super Tonus, Phyto Tonus, Tonus Plus) and the Vitol series (Vitol, Vitol Kholin and Vitol FEI) is given. The possibilities of using vegetable lecithins, phospholipid products and dietary supplements on their basis are shown as multifunctional prescription components in the production of functional and specialized food products.

Keywords: phospholipids, physiological role of phospholipids, vegetable lecithins, nutrition, phospholipid supplements, phospholipid products, functional foodstuffs.

The directions of technology perfection for obtaining high quality sugar has been considered, one of which is the use of technological supporting means. The information on the application of sulfite-containing preparations – sodium hydrosulfite and sodium sulfite to improve the white color of sugar has been systematized. Their optimal doses for the modern composition of semi-finished products of sugar beet production have been established. The samples of beet-root white crystalline sugar obtained using sulfite-containing preparations and without them (control sample) were evaluated by their color by the developed 4-point scale and by chromaticity in the solution. It has been proved that the use of sulfite-containing preparations allows obtaining sugar with perfectly and clearly expressed white color and chromaticity in solution on 16–24% lower than in the control sample. The grounds for the selection of a new functional group of technological supporting aids – sugar decolorants, assigned for color intensification of white sugar and reduction of its chromaticity in the solution are formulated. Their safety of application is shown. Sugar decolorants will complement the functional line of means used in the sugar production to improve its quality and competitiveness.

Technology of inactivation of microorganisms in food products

S.A. Romanchikov

A technology for the production of canned food products on a water basis has been proposed. The technology of inactivation microorganisms and the cessation of aerobic processes in food products is based on the use of modernized technological equipment and chemicals. The device for processing by an electric current (ohmic heating) allows to stop the reproduction of microorganisms (mesophilic, thermophilic bacteria and mold fungi) during short term storage of raw materials. The device for magnetic treatment of water provides an increase in the permeability of biological membranes of cells; change of hydrogen bonds; increases the electrical conductivity of water; accelerates the process and increases 1,6–2 times the solubility of the detergent in water when washing the packaging. The device for slowing down microbiological processes increases the shelf life of food products in liquid media, at an ambient temperature of 20–22°C for up to 8 days without the use of refrigeration equipment. Modernization of the device to slow down microbiological processes contributes to a 2-fold reduction in the amount of electricity consumed to stop the development of microorganisms. To achieve this goal, a chemical was included in the ingredients. Use in the technology of the drug (aspirin) increases the effectiveness of stopping aerobic processes. The effect of a constant electric current makes it possible to stop microbiological processes at specified parameters (frequency f 50 Hz, voltage U 36 V, current I 0,9–1 A). The activity of microorganism development was reduced is established. The possibility of spreading microbiological damage from one batch to another is excluded. The permeability of membranes of cells of fabrics is increased. The period of storage of products without deterioration of quality indicators is increased to 3 years. A device that allows storing food products on a water basis without the use of refrigeration equipment is proposed.

Keywords: conservation, storage of raw materials a short time, inactivation, electric current, ohmic treatment, increase in periods of storage of food, decrease of the activity of microorganisms, new ways of production of food.

G.A. Kupin, T.V. Pershakova, P.I. Kudinov, L.V. Mikhaylyuta, M.V. Babakina

Some investigation were done to define effectiveness of biological preparation Extrasol, Bactofit and Alirin action on phytopathogens Sclerotinia sclerotiorum and Bothrytis cinerea, which cause diseases (white and gray rot) of beetroot during storage. It was stated that biological preparation Bactofit is most active and effective against phytopathogenic microorganisms. Potential of the biopreparation to control beethroot diseases was estimated in in vitro experiments. Antogonistic activity of biological preparations Bactofit against Sclerotinia sclerotiorum and Bothrytis cinerea was investigated in beetroot cut under 25°C during 7 and 14 days and 7, 14, 28 and 35 days under 2°C. It was found that after storage of samples of beet roots at 25°C for 7 and 14 days the mean diameter of the affected area of Sclerotinia sclerotiorum in the control samples without making Bactofit was 4,5 and 7,5 mm, respectively; in the experimental samples infected with pathogenic, but are processed by the biological product, and 2,2 and 4,5 mm, respectively. At a storage temperature of 2°C beet root samples for 7 days, the average diameter of the Botrytis cinerea lesion zone in the control samples was 1,8 mm, in the samples with the introduction of a biopreparation no signs of the disease were observed. After storage of samples of beet root crops at a temperature of 2°C through 14, 28 and 35 days, the average diameter of the lesion zone Botrytis cinerea in samples not treated with Bactophyt was 3,0; 5,1 and 7,4 mm, respectively; in samples treated with a biological product – 0,8; 2,0 and 2,5 mm, respectively.. The feasibility of application of biological Bactofit to control the development of microbial deprivation of the beets during storage proved. Processing beet biologic Bactofit in combination with appropriate storage technologies can reduce quantitative and qualitative losses of crop production by preventing microbial deprivation.

A.S. Danilchenko, T.G. Korotkova, S.YU. Ksandopulo

The results of studies of the kinetics of evaporation of water during drying of the water–protein mixture at 60°C in isothermal conditions are given. The mixture was prepared from distilled water, pre-boiled at atmospheric pressure, which was poured into two Petri dishes of 20 ml each, and egg white added in an amount of 0,2 and 0,6 ml, respectively. Petri dishes were placed in a Memmert drying Cabinet equipped with forced convection and a temperature control equipment. The overhang with a Petri dish was weighed every 5 min on the analytical scales of Discovery. It was found that an increase in the amount of egg protein reduces the rate of evaporation of water in a period of constant drying rate and the rate of evaporation depends on the nature of the dissolved substance. At the end of the evaporation process, a translucent dried protein film is found at the bottom of the Petri dish, which indicates the conformational rearrangements of the protein in the process of moisture loss and partial dissolution of the protein in the water during evaporation.

Influence of thermal treatment on colour properties of dry potato puree

I.M. Pochitskaya, YU.F. Roslyakov, V.V. Litvyak, N.V. Komarova

A method for estimating the color change based on the processing of digital photo images before and after the temperature-time effects are proposed. Based on the received characteristics of the red–green–blue (RGB) color space, the color difference ДE was calculated. It is established that with increasing heat treatment temperature of the samples, the value of the color difference is sharply increased (by 50–80%). At a temperature of 120°C, the value of the color difference varies insignificantly and does not exceed 15 units even after a 2-hour exposure to temperature. However, with an increase in temperature 180–210°C, the color difference for the first 10 min increases substantially and after 60 minutes of heating changes insignificantly. The evaluation of the color change of dry mashed potatoes showed that the proposed method allows quantitative assessment of changes in color characteristics, is sensitive and more accurate, gives an opportunity to assess the color changes not perceived by a person. The received results demonstrate that controlling the temperature and duration of the heating process, it is possible to obtain the desired color of dry mashed potatoes, which is important, since color directly affects the organoleptic characteristics and consumer properties.

The quality control system of cognac products by expanding the list of control indicators has been improved. The research materials were brandy and distillates young and mature, aged from 1 year to 40 years, developed under different geographical zones of the CIS countries and the EU; the test samples of the distillate on the basis of grape, Apple and grain raw materials, samples of cognac distillates aged on oak rivets from oak wood Caucasian and French. Taking into account the results of many years of research, the choice of additional indicators of quality control of brandy and distillates is justified. Three groups of quality control criteria: single volatile impurity components of the composition, single extractable components of the composition and a block of design criteria based on the ratio of the concentrations of the components of the composition – are formed. Statistical processing of the research results was performed using a computer program Statistica 6.0. 22 criteria components of the composition, which can be used as single indicators of control, and 8 calculated indicators of quality control, allowing to confirm the authenticity of brandy products and to identify signs of falsification, to assess the compliance of the used raw materials to the declared name and the required quality standards, to detect the use of prohibited methods at the stage of processing grapes and during the aging of distillates in contact with oak wood, as well as violations in the distillation process and the facts of introduction of prohibited additives, have been established.
