Increasing the yield of juice and biologically active components from plant raw materials is an urgent task in the production of functional beverages. For this, fruit, berry and vegetable pulp was treated with enzymatic preparations of pectolytic action and the yield of juice was determined. Samples of pulp of each raw material were treated with enzyme preparations: Fructocyme P6-L, Fructocyme P, Fructocyme MA, in an amount of 0.03% of the pulp mass. Enzymatic hydrolysis was carried out at 50 °C for two hours, after which the amount of obtained juice was compared with the control sample. As a result, when adding Fructocyme MA to the pulp of apples and carrots, the juice yield increases by 8% and 17%, respectively. When Fructocyme P6-L is added to the pulp of kiwi, blueberries, grapes, the juice yield increases by 6%, 12 and 10%, respectively. To determine the effect of enzyme preparations on the yield of biologically active components, the previously selected enzyme preparations were added to all samples in an amount of 0.01; 0.03; 0.05; 0.07% of the pulp mass, and the total content of polyphenols was determined by colorimetry and anthocyanins. As a result of the experiment, it was found that in terms of the amount of polyphenolic substances extracted from the pulp, fruit and berry raw materials can be divided into three groups: raw materials with loose pulp, with pulp of medium density and raw materials with dense pulp. As a result, individual enzyme preparations and optimal modes of application were selected for each type of raw material. The dependence of the content of polyphenolic compounds on the dosage of the addition of enzyme preparations has been established.

Implantation Model

Damage to the tendon-ligamentous apparatus places serious limitations on a personʼs physical activity. Injuries are especially common in physically healthy people leading an active lifestyle, such as athletes. To treat such injuries in orthopaedics and traumatology, autoplastic operations are performed or prostheses made of synthetic or biological materials are installed. The known treatment methods, in spite of their effectiveness, have a number of serious drawbacks, which often limit their use. Therefore, the search for new approaches and materials for plastic ligaments is an urgent task. Today, biotissue prostheses are accumulating advantages over their synthetic counterparts. The most promising raw material for biological ligament prostheses, due to its availability in the required quantity and optimal size, is the flexor and extensor calf tendons. This paper aimed to develop a method for treating xenogenic tendon to manufacture ligament prostheses and assessing its biocompatibility in a heterotopic implantation model. To manufacture a ligament prosthesis, the raw material was subjected to mechanical cleaning and chemical-physical treatment, as well as treatment with supercritical carbon dioxide fluid with the addition of the nonionic surfactant Tween 80, which together contributed to effective decellularization and removal of other biologically active components, while maintaining the physical and mechanical parameters and natural fiberarchitectonics of native raw materials. The biocompatible properties of ligament prosthesis specimens made from the flexor and extensor calf tendons using this method were evaluated in a model of heterotopic implantation into the subcutaneous adipose tissue of rats. The results obtained confirm the promising use of this material, treated according to the proposed method, in clinical practice.

A mathematical model has been developed for the dependence of the solubility of pea flour protein on technological factors (concentration of enzyme preparations, duration of fermentation, hydromodule). The optimal technological parameters were determined at 1 + 2 stages of fermentation (concentration of enzyme preparations 170 units/g of DS or 1.5 %/g of protein, duration of fermentation was 4 hours, water module 1:15), at which the solubility and yield of pea protein reached 60 % of total content in raw materials. New information has been obtained on the effect of ultrasonic treatment on a suspension of pea flour to increase protein yield by 23–24 % compared with a control sample with an ultrasound wave amplitude of 10 microns and a processing time of 3 minutes, the final solubility is 83–84 %. The resulting protein product was characterized by high protein content, complementary amino acid composition; it is recommended for use in food purposes.

A study to determine the total content of phenolic compounds, flavonoids and mass fraction of iodine in chocolate using non-traditional raw materials has been conducted. The object of the study was chocolate products, containing stevioside, erythrol, germinated soy flour, enriched with iodine. Carrying out this set of studies is important because it will determine the content of phenolic compounds, flavonoids and iodine in the developed chocolate. Based on the obtained patterns, it is possible to determine the percentage of satisfaction of the recommended daily requirement and to set the recommended amount of consumption of the developed product per day. As a result of research, it has been found, that the total content of phenolic compounds in the control type of chocolate per 198 mg of GA / 100 g of the initial raw material is less compared to the sample of chocolate, where non-traditional raw materials were used. The results of the study correlate with the results of determining the total content of flavonoids. The developed types of chocolate exceed control samples by 229 mg of C / 100 g of the initial raw material. That satisfies 88.6% of the recommended daily amount. It has been found, that the developed type of chocolate is a carrier of iodine in the amount of 63 μg / 100 g. In the control sample of chocolate there were found only traces of mass fraction of iodine. It has been determined, that the use of germinated soy flour, enriched with iodine in the amount of 10%, due to the reduction of cocoa mass satisfies 42% of the recommended daily amount of iodine for a woman aged 30… 40 years of average labor intensity. The obtained results are useful and important because they will allow to develop recommendations for the consumption of chocolate using non-traditional raw materials. What will affect the solution of an important social problem - maintaining high efficiency, confrontation with environmental factors under the pandemic due to the influx of test substances

Introduction. This review examines the current state of technology for ultrasonic isolation of biologically active components from medicinal vegetal raw materials. The main emphasis is placed on "green" technologies that intensify the processes of isolation of components such as flavonoids.Text. Modern technologies imply the use of combined methods, including, in addition to ultrasound, significant grinding of raw materials before the extraction process, the use of supercritical solvents (liquefied gases) under excessive pressure. The effect of ultrasound power and temperature on the output of the extracted components was also considered.Conclusion. 1. To increase the yield of biologically active compounds from plant raw materials among various physical methods of extraction intensification, the use of ultrasound dominates. 2. Ultrasonic extraction can be divided into several main types: extraction in an ultrasonic bath, the use of submersible ultrasonic emitters, as well as the combination of ultrasonic extraction with additional types of influence. 3. In the literature, examples of the use of ultrasonic extraction for the isolation of phenolic compounds are most fully presented, it being noted that the parameters need to be selected individually for each individual plant. 4. The power of ultrasound and the nature of the extractant can affect the course of oxidative processes in the extract, and such phenomena are characteristic not only for too high capacities, but also for low ones. 5. Ultrasound can significantly increase the yield of biologically active compounds even in aqueous extraction of fresh raw materials. 6. The spectrum of extractants selection for ultrasonic extraction of plant raw materials is quite large. Both organic solvents (ethanol, methanol, ethyl acetate, acetone) and water can be used, as well as mixtures of various extractants.

Abstract The enterprises processing plant raw materials generate a fairly large amount of waste (secondary products), which can play an important role in solving food, environmental, and energy problems. This work improves the technology for the production of canned quince compote using a two-stage microwave heating of fruits and fruits filled with syrup prepared from infusion obtained from secondary products of cutting and peeling. It has been established that two-stage heating of fruits and microwave treatment of fruits filled with syrup in a glass jar promote an increase in the initial temperature of the product in the jars before sealing and thereby reduces the heat treatment modes. The infusion obtained from the secondary products of the heat-treated fruits provides a significant increase of biologically active components in the finished product. The experimental studies were used to construct a mathematical model for calculating the initial temperature of the product before sterilization, which makes it possible to establish intensive pasteurization modes. New modes of pasteurization of quince compote in various containers have been established. Physicochemical studies confirm the high quality of the finished product in terms of the content of biologically active components.
