Circular economy principles are based on the use of by-products from one operation as the raw materials in another. The aim of this work is to obtain extracts with high antioxidant capacity and resveratrol content for the superior capitalization of the biomass of Feteasca regala leaves obtained during vineyard horticultural operations in spring. In order to obtain a high-quality extract at an industrial level, an optimal extraction process is needed. Central composite design (CCD) was used for the experiment design, which contained three independent variables: the ratio of extraction solvent to solid matter, temperature (°C) and time (minutes). The evaluation of extracts was done by measuring the total antioxidant capacity of the extracts using photo-chemiluminescent techniques, and the resveratrol content using liquid chromatography. Process optimization was done using response surface methodology (RSM). Minitab software version 17.0 was used for the design of experiments and data analysis. Regression analysis showed that the model predicts 87.5% of the variation for resveratrol and 96% for total antioxidant capacity (TAC). The temperature had the biggest influence on the extraction yield. The optimal operational conditions for the extraction method applied had the following conditions: ratio e/m 2.92; 43.23 °C and 55.4 min. A maximum value of 34,623 µg ascorbic acid equivalent (AAE) /mL total antioxidant capacity and 182.4 µg/mL resveratrol content were obtained when the optimal extraction parameters where used. The values obtained in experiments proved that by using RSM an accurate model can be obtained for extraction of Feteasca regala leaves.

The aim of this research is to extract carotenoids from apricot fruits using a food solvent (ethanol) and a non-food solvent (propanol). In addition, it aims to study the effect of different extraction conditions, i.e., the extraction temperature (20-40-60)°C and the extraction times (4-8-12) hours, on the carotenoids yield in order to improve and develop extraction methods. The extracted carotenoids were determined using high-performance liquid chromatography (HPLC), and the studied carotenoids are α-carotene and β-carotene. It was found that β-carotene constitutes about 80% of the total carotenoids in apricots. The results indicated that the extraction yield using ethanol was low compared to the extraction yield using propanol. Propanol is the most suitable solvent for carotenoids extraction in comparison with ethanol. The temperature also had a significant effect on the extraction yield; at 20°C the extraction yield was very low, and 60°C was the optimum temperature for the extraction of carotene. The extraction yield significantly increased with time in the first hours of extraction, and there was no significant effect from increasing the extraction time for a period of 6-8 hours. Moreover, the pretreatment of fruits by freezing accelerated the extraction process and increased the extraction yield. The optimum conditions for extracting carotenoids were determined in the conditions of food extraction; the optimum conditions for extracting carotenoids are: extraction at 60°C for three hours with pretreatment by freezing as the extraction rate reached up to 6.36 mg/100 g using ethanol as a food solvent.

In this research, products with high quality were obtained from natural sources. The sensorial qualities, chemical characterization, and physical properties of gelatin extracted from chicken feet were compared with commercial gelatins. The extraction process was performed using acetic acid on a concentration ranging from 0.318% to 3.682%, processing time between 1.0 h and 8.4 h and extraction temperature between 43.3 °C and 76.8 °C. After the end of each assay, the yield was measured. Results showed that, under the best conditions, the collagen extraction yield was above 8%, and comprised 78.525 g/100 g of protein. Collagen analyzed by ICP-MS was composed of 99.44% of macro-minerals that are of great importance to human health. ATR-FTIR analysis showed that approximately 70.90% of the total protein from chicken feet is collagen, whereas, in commercial gelatin, only 30.31% is collagen. When comparing chicken gelatin with commercial gelatin, most sensory attributes were similar and chicken gelatin gained acceptance by more than 80% of the consumers. Additionally, the collagen films obtained from chicken feet and swine showed water absorption, odors, and texture characteristics similar to commercial material, such as latex and celofane. Consequently, due to its similarity to human skin, it is possible to apply it as a biocurative.

Abstract Glycosmis stenocarpa is a species of shrub found in the Northern provinces of Vietnam. Its roots contain different carbazolic derivatives, mainly Murrayafoline A (Mu-A), which exhibits valuable biological activities. In this study, we performed an extraction of Mu-A from the roots of G. stenocarpa and optimized this process using response surface methodology (RSM) according to a central composite design, with three independent parameters including extraction time (min), extraction temperature (°C), and solvent/material ratio (mL/g). Two dependent variables were the Mu-A content (mg/g raw materials) and extraction efficiency (%). The optimal conditions to extract Mu-A were found to be as follows: extraction temperature, 67°C; extraction time, 165 min; and solvent/material ratio, 5:1. Under these conditions, the Mu-A content and extraction efficiency were 38.94 ± 1.31 mg/g raw materials and 34.98 ± 1.18%, respectively. Mu-A exhibited antiproliferation and antitumor-promoting activity against the HepG-2 cell line. The present optimization work of Mu-A extraction from G. stenocarpa roots contributed to the attempt of designing a large-scale extraction process for the compound and further exploitation of its potential in vivo applications.

Іn the article an overview of the methods of extraction of oilseeds is carried out. The purpose of the work was to carry out the study of the extraction process at the installation for extraction in an electromagnetic intensifier (EEMI). The only way to ensure virtually complete oil extraction is the extraction method, in which the forces that convert the oil into a solution exceed the forces that hold oil in the extracted material. Today, the extraction method for oil extraction at Ukrainian plants is leading, as it provides greater yield of oil than with the use of the press process. The object of research is the use of rapeseed and soybean seeds, locally, oil obtained as a result of extraction of oilseeds. Experimental researches were carried out in laboratory conditions at the department "Processes and equipment of processing and food industries of a name of professor P. S. Bernik" of Vinnytsia National Agrarian University. Production tests of the laboratory sample of the extractor were carried out at PJSC "Vinnitsa OZHK". Physical and chemical researches of raw materials and intermediate materials were carried out. The optimum temperature regimes of the extraction process are established. The expediency and necessity of use as a solvent of ethyl alcohol is described. The research of rapeseed and soybean oils obtained as a result of extraction was conducted. The production of oil on the plant for extraction in an electromagnetic intensifier (EEMI) will enable the product to meet the requirements of regulatory documents and has a higher content of biologically active substances - tocopherols in comparison with traditional methods.
