Influence of drying conditions of sunflower seeds on phospholipids hydratability

L.A. Mkhitaryants, E.V. Denisova, G.A. Mkhitaryants
Annotation

The extraction of oils from sunflower seeds was carried out in the conditions which are brought closer to production i. e. all samples subjected to wet thermal treatment (WTT) in the modes accepted in oil and fat branch with their subsequent extraction by hexane. It is shown that the oils extracted from the seeds which have reached optimum humidity on standing (7,0–7,2%) are characterized by low degree of hydratability. Residual content of phospholipids in oils after water hydration makes 0,27%. The drying of seeds at any conditions, both cold, and hot air, promotes increase in transition of phospholipids to oils. This process is more expressed when using hot air and subjects more than above his temperature. It is established that drying of seeds exerts the greatest impact on hydratability of the extracted phospholipids. With increase in temperature of heating of seeds the residual content of phospholipids in oils after water hydration significantly decreases and at temperature of heating of seeds about 70 °C don’t exceed 0,04–0,05%. The revealed regularities can be explained with the changes proceeding in the phospholipid-protein complexes under the influence of technology factors. Drying of damp seeds has significant effect on durability degree the phospholipid-protein complexes, and the result of influence depends on polarity of phospholipids. The bonds of the most polar phospholipids which at the same time are not hydrated with a protein-polysaccharide part of seeds in the course of drying are consolidated the more, than temperature of heating of seeds is higher. As a result not hydrated phospholipids don’t pass into oils even from the seeds which have passed the WTT. The bonds of less polar, easy-hydrated groups of phospholipids with components of seeds weaken, collapse in process WTT, and the easy-hydrated groups of phospholipids pass into oil. The obtained results demonstrate that drying of seeds by the drying agent with high temperature allows to increase considerably total amount of the extracted phospholipids at simultaneous improvement of degree of their hydratability.

E.A. Ravnushkin
Annotation

The work is devoted to the study of the processes of thermal vacuum drying of soft cheeses. The objects of research were the following brands cheeses “Adygei cheese”, “Roquefort” and “Russian Camembert”. The experiments on barovacuum drying of soft cheeses with different values of the depth of the residual and excess pressure are conducted. It is found that with increasing magnitude of overpressure warming rate of the product is increased, which entails a reduction of the drying time. The lowest drainage time was observed in the magnitude of the excess pressure of 50 kPa and amounted to 290, 190 and 220 minutes, respectively, for cheeses “Adygei cheese”, “Roquefort” and “Russian Camembert”. To reduce the duration barovacuum drying is also possible by reducing the residual pressure. It was found that with an increase in the residual pressures from 4–5 to 6–7 kPa drying time increases by 10–20 minutes. We investigated the organoleptic characteristics of dehydrated cheese. Higher organoleptic characteristics observed when drying with a lower value, and more surplus value of the residual pressure. The effect of the residual pressure on the specific energy consumption is established. Changing the residual pressure from 4–5 to 6–7 kPa leads to ambiguous change in the value of specific energy consumption: for cheeses “Adygei cheese” and “Russian Camembert” a decrease in energy consumption by 3,5 and 1,7%, respectively, and for “Roquefort” cheese – increasing energy consumption by 6,8%.

Grain dust (GD) on grain processing enterprise has a negative impact on production and the environment. With a minimum concentration in air GD is flammable and potentially explosive substances, remains a major cause of fires, fire and smoke. Each time you move the grain inevitable loss of physical weight of GD. Grain dust is a potent allergen and negative effect on the health of employees, leading to occupational diseases. Grain dust emissions into the environment lead to a breach of environmental and health standards and regulations. On enterprise rice processing “Southern Rice Company” as a result of reconstruction cyclone-bag filter have been introduced. Analysis of experimental data and performed calculations showed that the total emissions of pollutants into the atmosphere decreased. Monitoring the filter cyclone showed that he worked effectively for about three days, after which clogged and had to turn off the equipment. We investigated a cyclone-bag filter having a flat bottom and equipped with a pulsed jet and an electronic control unit. Dust extraction takes place in the process of filtering through the fabric. The calculations and determine the actual air pressure on the fabric. It was found that the required 2-cyclone filter to ensure the normal operation of the equipment and compliance with safety standards. The actual excess loading on the fabric is 60%, which is unacceptable and leads to an accelerated filter clogging and reduce its performance in the air.

Annotation

The mathematical models are obtained that adequately describe the dependence of the organoleptic quality indices of the vegetable desserts, i. e. confitures, from the mass fractions of their components in formula. Celery root is used as the main raw material, which has a high content of macro- and micronutrients, such as pectin, dietary fibre, minerals, vitamins, and other functional components influencing the metabolism in the human body. The confiture gelling agent selected is agar-agar, which has good gelling properties, does not require special conditions for the gelling, such as acidity and sugar concentration, and does not affect the taste and flavour of the finished product. In order to optimize the formula components, we studied three new confitures based on the celery root with added sugar, citric acid, and agar-agar: with carrot, with beetroot, and with lemon peel; these additional ingredients give the products original organoleptic properties. To reduce the number of tests and obtain reliable information the method of multi-factor designs for tests was used and the second-order rotatable central composite design of experiments was selected providing the same dispersion of the projected quality indices for the new confitures. The influence of the ingredient ratio was studied on the quality indices of the finished products, i. e. their appearance, colour, texture, aroma, and taste. The desirability function was used as the general quality index. The optimum ratio of the development vegetable dessert formula ingredients was determined. The degustation evaluation of experimental samples confirmed the high quality of the new products.
