The intensification of dehydration process of pectin-containing raw materials

Avocado is one of the most valuable products, as it is characterized by a high content of biologically active substances, including vitamins, mineral elements, fats, and dietary fibers. According to a complex of organoleptic and physicochemical indicators, the consumption properties of avocado fruits from different countries of origin, which are sold in Ukraine, have been investigated. Among the organoleptic indicators, the state of peel and pulp, taste, and smell has been determined according to the developed scoring scale. It has been established that the Haas type (Colombia) fruits have a light green pulp and a deep green peel that does not lag well behind the flesh, they are quite firm, the taste is watery, and there are no significant defects, the stem is not damaged. Haas (Israel) avocados had light green pulp and a brownish-black peel that separated from the flesh very well, with little evidence of pollination, a nice buttery flavour, and a nice texture. There is a slight peel defect (pollination mark) with an area of less than 4 cm2, which does not affect the fruit's flesh, and the stem is not damaged. The fruit of the Fuerte type (Israel) had a light green pulp and a deep-green peel that did not lag well behind the flesh, a somewhat grassy taste, and a loose flesh texture. The fruit had a defect in the peel (lens) with an area of less than 6 cm2, which does not affect the fruit's flesh, and the stem is not damaged. It has been found that the researched types of avocado fruits from different countries of origin differ in shape, size, and the ratio of peel, pulp, and stone. From the physicochemical parameters, the mass fraction of moisture, the content of dry soluble substances, active acidity, the content of ascorbic acid, and the fatty acid composition of lipids of avocado fruits have been determined.

“…As the firing temperature increases, lime recrystallization processes take place, after which the sintering process begins. The latter interferes with the access of water to CaO particles during quenching, and lime, remaining chemically free, becomes inactive for reaction with water [12], [27].…”

The paper presents research on increasing the activity of milk of lime in beet sugar production using vapor condensation cavitation. The work aimed to develop a rational way of activating milk of lime using the effects of vapor condensation cavitation and its hardware design, substantiating the optimal values of the process parameters. It was established that to increase the activity of milk of lime at a steam potential of 0.18 MPa, an optimal consumption of water vapor using vapor condensation cavitation is required, which is 1 .75 – 2.0% to the weight of the suspension. This is ensured by the action of the combined CaO particles with the bulk of the steam, due to which the Their additional solution is due to the t-plot, which occurs through the boundary layer from the bubbles. As a result, a pre-saturated, water-lime suspension is created, in which the It is the number of dissolved calcium ions. It has been proven that the water vapour-treated suspension is 1.5 times lower It expands and has a volume of sediment of the solid phase in the medium that is 10% larger than that of processed suspension. Such a study is indirect evidence of the increase in the dispersal of these systems after Her husband's work. By increasing the activity of milk of lime, it is possible to increase the effect of cleaning juices at various stages of the technological process and reduce the consumption of limestone for the production of granulated sugar.

Selection in meat cattle herds requires caution due to the manifestation of inbred depression in traits that affect the economics of this livestock industry. This paper analyses the productivity of inbred and outbred bull calves of the Ukrainian meat cattle breed and justifies methods of pair selection in purebred herds with natural pairing. In bull calves, the growth of animals and traits of their meat productivity after slaughter were considered. Inbreeding was determined based on their pedigree. Inbred animals tended to have a growth rate of 10.2% from birth to 8 months of age. Afterwards, their average daily gain in live weight decreases sharply compared to outbred peers, who grow faster over a more extended period. From 8 to 18 months of age, it is probably (p >0.95) higher by 27.3% compared to inbred animals. Inbred bull calves have higher variability (Cv,%) in average daily gains. This indicates different adaptations to the environment during the suckling period and after weaning. Outbred animals tend to gain 2.3% of body weight at 12 months, 4.7 at 15 months, and 10.3% at 18 months. Its variability with age decreases by 7.4 points in inbred bull calves and 0.4 points in outbred ones, from 8 to 18 months. The inbred animals spent 29.5% more feed per kg of gain (p >0.95) than the outbred ones. Inbred bull calves vs outbred ones at 15 and 18 months of age tend to improve the expression of meat forms by 1.3 and 2.7%. They are relatively shorter and have a more rounded barrel. As a result, they have a shorter period of rapid growth. With the small size of the Ukrainian meat cattle population, one of the most important problems is reducing genetic variation in beef productivity traits and manifesting inbred depression in them. In purebred commercial herds, the mating of close animals should be avoided. To do this, an "order" for bulls should be made, and pairs should be selected without using inbreeding at different grades. Thus, outbred bull calves will reach live weight more quickly, spending less feed per growth unit, and have better basic slaughter traits.
