STUDY OF THE CONTENT OF ANTIOXIDANTS AND THEIR ACTIVITY IN CONCENTRATED EXTRACTS OF CRANBERRY (VACCINIUM OXYCOCCUS), SEA BUCKTHORN (HIPPOPHAE RHAMNOIDES L.), BLACKBERRY (RUBUS FRUTICOSUS), VIBURNUM (VIBURNUM OPULUS L) AND MOUNTAIN ASH (SORBUS AUCUPARIA L.

Extracts and their concentrates can be considered as a source of biologically active ingredients of food products and as food additives to increase the consumption of useful substances of berries. The benefits gained from their use lead to the development of advanced technologies that can allow them to be extracted from the feedstock without significantly compromising the biological activity from the feedstock. In this paper, we studied the content of antioxidants and their activity in concentrated extracts of cranberry (Vaccinium Oxycoccus), sea buckthorn (Hippophae rhamnoides L.), blackberry (Rubus fruticosus), viburnum (Viburnum opulus L.) and mountain ash (Sorbus aucuparia L.) berries. For all extracts, the total content of phenolic compounds, flavonoids and anthocyanins, antioxidant activity according to the DPPH method and iron-reducing antioxidant activity (FRAP) were determined. Concentrated extracts of viburnum contain the largest amount of phenolic compounds (9.3±0.3 mol HA/l), flavonoids (1.96±0.08 mol K/l) and anthocyanins (0.26±0.02 mol CG/l) among the studied extracts. There is also a high total content of phenolic substances and flavonoids in blackberry and rowan extracts (5.7 mol HA/l, 1.33 mol K/l and 4.7 mol HA/l, 192 mol K / l, respectively). The antioxidant activity of the extract of viburnum berries showed a directly proportional dependence on the content of biologically active compounds in it: DPPH-method-2.4 mg / ml; FRAP-method-39.99 mmol Fe2+ / kg. Also, high levels were found in concentrated extracts of blackberries, sea buckthorn and mountain ash. It is the extracts of viburnum, blackberry and mountain ash that are recommended to be used in the production of food products to enrich them with biologically active substances and give them antioxidant properties. Cranberry and sea buckthorn extracts can be used in combination with other extracts.

ASSESSMENT OF THE STATE OF PLANTINGS OF SECONDARY SCHOOL No. 19 CITIES OF YOSHKAR-OLA

The purpose of the study is to analyze the sanitary condition of tree and shrub vegetation on the territory of school No. 19 in the city of Yoshkar-Ola. This work is relevant, since the school is a place for long-term stay of children of school and preschool age and the natural environment is an integral part of their educational activities. To determine the assessment of the state of the stand, the coefficients of the state of plants are calculated: the states of individual trees are determined by the external signs of a 5-point scale. Next, the coefficients of the state of the tree species are calculated according to the corresponding formula. The coefficients of the state of the stand as a whole are also found as the arithmetic mean of the coefficients of the state of individual tree spe-cies. As a result, an assessment of the state of the stand according to this gradation was deter-mined. Woody plants growing on the territory of secondary school No. 19 in Yoshkar-Ola were examined. A total of 35 species of coniferous and deciduous plants have been identified. Most species are characterized by a weakened state. Plants of hawthorn-blood-red, poplar × 'Soviet Py-ramidal', prickly plum and mountain ash are the most weakened. The condition of the plantings as a whole is assessed as weakened. It is recommended to carry out agrotechnical measures for plants and cleaning of dead specimens.

Topophilia: a Cistercian monastry in Australia's land of fire

<p>On a portion of sacred Aboriginal land, formerly the resting place of Coranderrk Station, lies Tarrawarra Abbey, Australia’s solitary Cistercian monastery. Established in 1954, Tarrawarra Abbey represented an opportunity for a community to emerge that encouraged the interaction and collaboration between European and Aboriginal peoples. Instead, the historical discourse and relationship between Tarrawarra’s monks and Victoria’s Aboriginal people reflects a broader narrative of Australia’s past. Aboriginal histories, their perceptions of the natural world, strategies for managing and caring for the land as well as dispossession are treated as marginal and often invisible elements within a European history, architecture and life. Additionally, with the eradication of Aboriginal people from their position as protectors and guardians of their environment, combined with a changing climate, areas of Victoria’s landscape are now under serious threat as fire-storms continue to plague its most valuable forests. On February 7, 2009, the most destructive fire-storm in Australia’s history ripped through Victoria. With no Aboriginal influence on the landscape to control fuel, ‘Black Saturday’ as it became known, executed centuries old mountain ash trees, forcing them into a compromised state, a landscape trap. Consequently, the surviving stands of mountain ash and vulnerable stands of recent re-growth need protecting. This thesis addresses how site and sensory-based Aboriginal perspectives on the relationship between people, architecture and landscape can drive the manifestation of a ‘new’ and reinterpreted Cistercian monastery. Through this process the monastery will become an architectural scar. As a scar, the reinterpreted monastery and its community of monks and Aborignals will not only contribute to the protection of Kinglake National Park’s injured mountain ash forest and heritage stone water structures, but also assist in the mending of a torn relationship between two cultures.</p>

BIOCHEMICAL COMPOSITION OF FRUITS OF SOME REPRESENTATIVES OF THE GENUS SORBUS L. IN COL-LECTION OF THE SOUTH-URAL BOTANICAL GARDEN

Mountain ash (Sorbus aucuparia L.) is a valuable medicinal and food plant that is widely used in practical medicine and in amateur horticulture. The purpose of this study was to determine the content of ascorbic acid, organic acids, tanning substances and flavonoids in the fruits of some representatives of the Sorbus genus of the collection of the South-Ural Botanical Garden-Institute and to identify the most promising taxa. For analysis, fruits were collected in the full ripening phase and dried to air-dry state. Phytochemical studies were carried out according to conventional methods. The object of comparison was the official pharmacopoeia species – Sorbus aucuparia. Analysis of the obtained data found that the fruits × Sorbocotoneaster pozdnijkovii and Sorbus sibirica outperformed the natural form (Sorbus aucuparia) in terms of ascorbic acid content by 11.54 and 43.27%; Organic acids by 24.11 and 60.84%; Tanning substances by 3.49 and 43.23%; Flavonoids by 44.19 and 12.79%, respectively. The obtained results allow to recommend these taxa as promising sources of raw materials for production of biologically active substances in production of natural food products and food additives.

Interacting Fire, Logging and Climate Change has Sprung a Landscape Trap in Victoria’s Montane Ash Forests

Ecosystems are influenced by multiple drivers which shape ecosystem state and biodiversity. In some ecosystems, interactions and feedbacks between drivers can produce traps that confine an ecosystem to a particular state or condition and influence processes like succession. A range of traps have been recognized, with one of these – “a landscape trap” first proposed a decade ago for the tall, wet Mountain Ash and Alpine Ash forests of Victoria, south-eastern Australia. Under such a trap, young flammable forest is at high risk of reburning at high-severity, thereby precluding stand maturation, and potentially leading to ecosystem collapse. These young forests are more common because recurrent wildfire and widespread clearcutting have transformed historical patterns of forest cover from widespread old-growth with small patches of regrowth embedded within it, to the reverse. Indeed, approximately 99% of the montane ash ecosystem is now relatively young forest. Based on new empirical insights, we argue that at least three key inter-related pre-conditions underpin the development of a landscape trap in montane ash forests. A landscape trap has been sprung in these forests because the pre-conditions for its development have been met: We show how inter-relationships between these pre-conditions, leading to frequent high-severity fire, interacts with life history attributes (e.g. time to viable seed production) to make montane ash forests (e.g. which have been highly disturbed through logging and frequent fire) vulnerable to ecosystem collapse. We conclude with the ecological and resource management implications of this landscape trap and discuss how the problems created might be rectified.

The content of carotenoids in plant fruits of Sorbus L. species and varieties when introduced in the North (Komi Republic)

The paper presents data on the study of the content of carotenoids in plant fruits of different Sorbus species and varieties when introduced in the Komi Republic. As a result of a biochemical analysis, the accumulation of various amounts of carotenoids has been revealed: from 2,6 to 43 mg/%, depending on the species, sample and variety. The author compared the content of this group of substances in raw materials of plants introduced in the Komi Republic with the ones growing in other regions of Russia (Republic of Bashkortostan, Republic of Mordovia, Saratov, Penza, Moscow Region and others). It has been shown that under northern conditions in rowan fruits the value of the total carotenoids prevails in representatives of the Sorbus section with an East Asian range ( S. pohuashanensis , S. discolor , S. amurensis ), except the Far Eastern species S. sambucifolia . A different content of carotenoids in the plant fruits of S. aucuparia samples has been established: the maximum is in the sample from Yoshkar-Ola, which is 3-5 times higher than that in S. aucuparia from the Komi Republic. The content of this group of substances in the rowan fruits of the three studied varieties (Businka, Rubinovaya and Sorbinka) has been determined; their predominance in the Sorbinka variety has been shown. The study of the biochemical composition of plant raw materials of mountain ash species and varieties with the highest content of carotenoids when introduced in the North should be continued in order to further assess its qualitative composition and to develop recommendations for its use as a medicinal product, as well as a source of functional ingredients for pharmaceutical and food industries.

VITAMIN VALUE AND SAFETY OF COTTAGE CHEESE WHEN INTRODUCING NATURAL PRESERVATIVES OF FRUITS AND BERRIES INTO ITS RECIPE

The purpose of these studies was to determine how much it is possible to extend the shelf life of cottage cheese and increase its vitamin value due to berries and fruits of some fruit and berry plants. The research was carried out in 2021 on the basis of the laboratory of the Department of Technology of Storage and Processing of Agricultural Products of the I. A. Bunin Yelets State University. Kefir with a fat content of 3.2% was used as the main raw material. The fruits and ber-ries were thoroughly washed and crushed into a pulp, then added to kefir and mixed evenly. Kefir was heated in a water bath and protein coagulation occurred at a temperature of 55 ° C. The result-ing mass was filtered through a non-woven fabric "Agrotek", applying the same load. Glass jars with a volume of 0.25 liters with tin lids with threads were sterilized by steam in a water bath at t=100 oC for several minutes. The jars were filled with ready-squeezed cottage cheese. The addi-tion of crushed fruits and berries to cottage cheese changes some of its organoleptic characteris-tics: orange pulp - consistency, sea buckthorn-smell and taste, aronia - color. The introduction of fruits and berries into the recipe of cottage cheese preserves the moisture and fat content within the standard. The dynamics of the acidity of cottage cheese is greatly disturbed only by the fruits of sea buckthorn. The addition of sea buckthorn fruits to it contributes to an increase in the humid-ity and acidity of cottage cheese in a greater degree. The shelf life of cottage cheese with the addi-tion of sea buckthorn fruits at a temperature of 4 oC was 8 days, the other options - 12 days. When stored in room conditions (t=20 oC), the control cottage cheese and with aronia spoiled after 5 days. Adding fruits to it slowed down the appearance of mold: cranberry - for 1 day, mountain ash - for 2 days, orange-for 3 days. The most organic acids are added to the cottage cheese by sea buckthorn fruits and cranberry berries, flavonols - the fruits of common mountain ash, coloring substances and anthocyanins - aronia, ascorbic acid and carotenoids, including β-carotene - aronia and mountain ash.

VITAMIN VALUE AND SAFETY OF KEFIR ENRICHED WITH FRUITS AND BERRIES

The research was conducted in 2021 on the basis of the laboratory of the Department of Technolo-gy of Storage and Processing of Agricultural Products of the I. A. Bunin Yelets State University. The aim of the research was to find out the comparative effect of adding some fruits and berries on the vitamin value of kefir. As the main raw material for the experiment, drinking pasteurized milk was used according to the state standard 31450-2013. Cranberry berries were used frozen from the retail chain, the rest were collected in the Yelets district and frozen before the start of the experiment. Of all the berries used, only cranberries and mountain ash did not worsen the organo-leptic parameters of kefir. Judging by the acidity of kefir, the shelf life of the control sample and with cranberries was the longest – 14 days. On the 12th day, the options with mountain ash and black currant went beyond the standard for acidity. The shelf life of kefir with sea buckthorn fruits was only 9 days. The addition of fruits and berries to kefir increased the content of biologically active substances in it: rowan-dry substances, carotenoids and flavonols, and black currant-coloring substances and anthocyanins. Taking into account the organoleptic indicators, the shelf life for acidity and the content of useful substances in kefir, it is necessary to single out the option with the addition of rowan fruits as the most successful.
