Aerial part of Nepeta are characterized by high antimicrobial activity and fungicidal action against mold fungi, used in folk medicine, as ingredient in recipes for sausages, liqueurs and soft drinks, vegetable and fruit canned food, in the manufacture of vermouth. Ukrainian variety 'Melody' was created specifically for growing in the Forest-Steppe zone, and variety 'Peremozhets' – in the Steppe zone. Data on the yield aerial part and essential oil Nepeta was determined. The dry aerial part of plants N. cataria we used to create a dry spicy mixture for sweet dessert dishes. Quantitative content and qualitative composition of essential oil of plants by organs and phases of vegetation are presented in the article. In our research we used essential oils obtained by hydro distillation procedure for 2 h using Clevendger-type apparatus from the flowering parts of plants N. cataria 'Peremozhets' and 'Melody'. Investigate of components was carried out by high effective gas chromatography with HP 6890 chromatograph coupled with HP 5972 mass selective detector. The most abundant components of Nepeta essential oil was citral, geraniol, as well as nerol, citronellol, citronellal, carvacrol, camphor, eugenol. We proposed fractional distillation of essential oils to obtain a line of flavors with stable sensory and physicochemical indicators for food industry. The separation of essential oils into fractions was carried out on a pilot installation of fractional distillation DFD (Device of Fractional Distillation). Calculations of parameters controlled dispersal of essential oils (residual pressure, temperature regimes, number of theoretical plates, reflux number) were carried out. During fractionation of essential oil of N. cataria four fractions were obtained with a content of 96 ±0.5% to the total mass of samples. Sensory and physicochemical analysis of aromatic fractions announced them as promising flavours for food industry.

The growth of the essential oils market is explained by the growing demand for natural and organic products. Today, the global aromatherapy market with essential oils is growing, and demand for essential oils is increasing at the same rate. The studies are dedicated to the valuable essential oil culture ‒ fennel, the spread of which in the forest-steppe zone of Ukraine will allow to obtain high profitability by agro-forming of different forms of ownership and will help to provide the Ukrainian market with raw materials of appropriate quality. The article offers a solution to the pressing issue of expanding the area of new unconventional culture in the conditions of the Forest-Steppe of Ukraine by improving technological measures in the cultivation of culture. The basis of scientific research is the study of sowing terms (1st decade of April, for soil LTR 6-80C), (2nd decade of April, for LTR of soil 10-120C); row spacing (5, 30, 45 and 60 cm) and seeding rates (1, 1.5 and 2 million sprouting seeds per hectare). Among the plans of the research tasks were: to conduct the accounting of yields and to determine indicators of seeds quality (the content of essential oil in fennel seeds and its conditional yield per hectare of sowing), depending on the studied factors. Crop accounting was performed by continuous submerged threshing. The yield was brought to 100% purity and standard humidity according to the method described by V.O. Moiseychenko and V.O. Yeshchenko. Mathematical data processing was performed according to the method of B.A. Dopehova. The results of the research show that the sowing variants in the first decade of April, with a wide-row method (45 cm) sowing rate of one million sprouting seeds per hectare, yielded the optimum yield of fennel – 1.48 t / ha. In the same variant, the maximum content of essential oil was obtained – 6.23% and its yield from the hectare sowing area‒ 59.2 kg.

Thymus Serpyllum

Wild thyme (Thymus serpyllum L.) is a popular remedy regarding both traditional and conventional medicine. It is used as the antiseptic, aromatic, expectorant, stomachic, antispasmodic, carminative and preservative substance. For the purpose of this paper, wild thyme essential oil was isolated from the dried herb T. serpyllum by hydrodistillation. Original semi-industrial distillation device SP-130 performing distillation by water and steam was used for the hydrodistillation of T. serpyllum essential oils. The temperature during the hydrodistillation in the device SP-130 ranged from 100?C - 102?C at atmospheric pressure, and the whole process lasted 5 hours. The isolated essential oil is a liquid of light yellow colour and the odour characteristic of the genus Thymus. Obtained yield of essential oil was 0.08 %, with 65 components identified in the tested essential oil. The most represented chemical groups are sesquiturpene hydrocarbons with 35.1%, and oxygenated sesquiturpenes with 34.8%. The main components of essential oil of T. serpyllum were: trans-nerolidol (24.2%), germacrene D (16.0%), thymol (7.3%), ?-cadinene (3.7%) and ?-bisabolene (3.3%). The essential oil showed significantly better ability to neutralize DPPH free radicals (IC50 = 0.503 ?L / mL) compared with synthetic antioxidants BHA and BHT. Synthetic chemical compounds such as BHA and BHT are used in food industry as antioxidants due to their ability to prolong the shelf-life of foodstuffs by protecting them against deterioration caused by oxidation, such as fat rancidity, colour changes, degradation of the flavor and loss of nutrient value. In recent years, there is a considerable interest in finding natural compounds that could replace sinthetic antioxidants because of adverse toxicological reports on many synthetic compounds. Lamiaceae herbs and their essential oils or extracts application has proven to be the effective preservation agents for the extension shelf-life of foodstuffs, indicating their potential use in food industry as functional ingredients and food additives. The antioxidant activity of extracts from some Lamiaceae herbs is comparable to that of the most common synthetic antioxidants BHT and BHA. Free radicals are a major cause of many degenerative diseases, such as atherosclerosis, cancer, cardiovascular diseases, inflammatory bowel diseases, skin aging, old age dementia and arthritis. Epidemiological data and randomized clinical trials provide sample indications that antioxidants play a fundamental role in the prevention of cancer and cardiovascular diseases. They act as scavengers of reactive oxygen species and metal chelators that protect human cells and reduce oxidative damages. Natural antioxidants are important in the food industry because they can have a double functionality, that is, they can be useful as a food preservation agents while providing important health benefits for humans by maintaining our health and preventing disease. This investigation showed that the essential oil of T. serpyllum can be an important source for the production and application in the food industry as nutritional supplements, functional food components or natural food antioxidants.

Essential oils have great potential in the field of the food industry as they can effectively prevent the presence of several bacterial and fungal pathogens. Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of the secondary metabolism. The main goal of this work is to perform a qualitative evaluation of the antibacterial properties of 24 chemotyped essential oils against the growth of Bacillus subtillis. These Gram-positive bacteria are responsible for “rope” disease in bread preservation processes. The study was carried out using the method of disk-diffusion in agar. Biological activity was observed in five essential oils: Cymbopogon martinii var. motia, Thymus vulgaris QT Linanol, Thymus satureioides, Mentha piperita and Eugenia caryophyllus. The first three have in common the presence of some mono terpenic derivatives—Geraniol, Linalool and Carvacrol, respectively—with strong antimicrobial effects. The Cymbopogon martinii essential oil is one of the botanicals with the highest geraniol content (up to 80.53%) and showed more activity antimicrobial than the others. A contributing role of this knowledge could be the design of Cymbopogon martinii essential oil formula, which can be used in bakery industry as a preservative, such as nano-encapsulation for bakery doughs, active packaging of baked products or surface disinfectants.
