Official Data

Over the last decade, in Croatia are growing a lot of new plantations of chokeberry (Aronia melanocarpa). While it was a plant species that was mostly planted on the home grounds, today is more intensive cultivation plants and have been growing more than 200 family farms in Croatia now. Although there is no official data on the total area of chokeberry in Croatia, according to the data from the other source, it can be said that the production is about 100 ha total. Due to good adaptability to different agro-ecological conditions, most of the new and intensive plantations in Croatia are certified for ecological/organic production. Namely, due to their nutritional value, high content of polyphenols and strong antioxidant activity, fruits and their products (juice, syrup, tea, jam, etc.) are highly demand products on the market of healthy and ecological foods. Therefore, knowledge of ecological fertilization technology is very important in the production of this fruit

AbstractThe interest in edible sea grapes (Caulerpa lentillifera) is increasing due to their potentially beneficial effect on human health. This macroalga, already used for direct and indirect human consumption, is grown in aquacultures in Vietnam and The Philippines. Here, the edible fronds of sea grapes were examined for their antioxidant activity (AOA) at light intensities from 140 to 300 µmol photons m−2 s−1 and compared to commercially dehydrated C. lentillifera and the renowned highly antioxidative fruits Pomegranates (Punica granatum), Goji (Lycium barbarum and L. chinense) and Aronia (Aronia melanocarpa) berries, using an ABTS+-assay for all samples. AOA of fronds exposed to 300 µmol photons m−2 s−1 for 14 days increased by about 320% from the initial value of 72.2 ± 5.6 to 232.2 ± 34.2 Trolox Equivalents (TE) mmol 100 g−1 dry weight (DW) onto the level of Pomegranates (272.8 ± 23.0 TE mmol 100 g−1 DW). This application could be used as a post-cultivation treatment in sea grape cultures to increase the quality and nutritional value of the product.

Geographical Position

The paper deals with the syntaxonomy of vegetation on the sandy outcrops in the Pechora (Malozemelskaya and Bolshezemelskaya) tundra. The vegetation was classified using the Brown-Blanke approach. Communities were referred to 3 associations: Arctostaphylo alpini—Empetretum hermaphroditi (Zinserling 1935) Koroleva 1994, Elymo—Festucetum arenariae (Regel 1923) Nordhagen 1955 and Rumici graminifoliae—Festucetum sabulosae ass. nov. Five new variants were suggested within the first association and 2 subassociations and 4 variants within the last one. Syntaxon description and phytocoenological tables are presented. The vegetation on each sandy outcrops represents a complex of communities fragmentary located on the scars area. Subass. inops of ass. Rumici graminifoliae—Festucetum sabulosae is more common in the Ortina river basin and occurs at the bottom of blowing hollows. Syntaxa of ass. Elymo—Festucetum arenariae and var. Festuca rubra of ass. Rumici graminifoliae—Festucetum sabulosae are situated at the mobile sands in the central part, while var. Arctous alpina of ass. Rumici graminifoliae—Festucetum sabulosae occurs on a periphery of out­crops where substratum is stable. The variants inops and typicum of ass. Arctostaphylo alpini—Empetretum hermaphroditi occuring in the Sedujyakha river basin occur mostly in the centre of sandy outcrops, and the other ones can be met on their periphery. Ecological conditions determine poor diversity of syntaxa of the association level. Geographical position (the Sedujyakha river basin belongs to the northern hypoarctic tundras, the Ortina river basin — to the southern hypoarctic ones), geomorphology (in the first site — tops of hills and ridges, in the second one — watershed areas) and area of sandy outcrops (200—3000 m2 for the first and 61000—418000 m2 for the second site respectively) are the reasons for the less diverse communities found in each study site. A great number of variants is conditioned by succession stages of vegetation and instability of the substrates.

The Impact

The benefits of natural honeybee products (e.g., honey, royal jelly, beeswax, propolis, beevenom and pollen) to the immune system are remarkable, and many of them are involved in the induction of antibody production, maturation of immune cells and stimulation of the immune system. The type of plants in the geographical area, climatic conditions and production method have a significantly influence on the nutritional quality of honey. However, this variability can influence consumer liking by the sensory attributes of the product. The aim of this work was to compare the most popular honeys from Poland in terms of nutritional value, organoleptic properties and antioxidant activity. In the study, five varieties of honey (honeydew, forest, buckwheat, linden and dandelion) from conventional and organic production methods were tested. The nutritional characteristics of honey samples included acidity, content of water, sugars, vitamin C, HMF and phenolics (total and flavonoids), while honey color, taste, aroma and consistency were investigated in the organoleptic characteristics. The antioxidant activity was determined in water- and ethanol-soluble honey extracts using DPPH and ORAC tests. The results showed that organoleptic and nutritional characteristics of popular Polish honeys differ significantly in relation to plant source and production method. The significant effect of honey variety on the content of HMF, saccharose and phenolics, as well as acidity and antioxidant capacity were noted. The impact of variety and variety × production method interaction was significant in the case of the content of vitamin C, glucose and fructose. A visible difference of buckwheat and forest honeys from other samples was observed. The highest content of total phenolics with antioxidant activity based on the SET mechanism was found in buckwheat honeys, while forest honeys were richer in flavonoids.

The leaves and seeds of the faba bean are good sources of L-3,4-dihydroxyphenylalanin (L-dopa), and are usually eaten with thermal cooking methods. However, little information is available on the effect of thermal treatments on their nutritional value. We compared the changes in color, contents of L-dopa, vitamin C (Vc), total phenolics (TP), total flavonoids (TF) and antioxidant activity after dry heating or steaming faba bean leaves and seeds. The young leaves provided higher values of all the estimate factors, regardless of the thermal treatment. Steaming significantly degraded nutritional values of the leaves, but less changed in seeds, whereas dry heat maintained these attributes. The contents of L-dopa, Vc, TP and TF were shown to have strongly positive correlations with antioxidant activity in the leaves, whereas only L-dopa content was positively correlated with antioxidant activity of the seeds. Faba leaves contained relatively high L-dopa which possessed strong antioxidant activity compared to the Vc. As L-dopa is an important contributor to the antioxidant activity of faba leaves and seeds, consuming L-dopa from leaves may provide beneficial effects not only regarding Parkinson’s Disease.

AbstractDried fruits are an excellent alternative to unhealthy snacks. Twelve commercially available dried fruits were selected: dates, raisins, prunes, Goji berry, chokeberry, rose hip, sea buckthorn, berberis, physalis, haritaki, noni and juniper. The nutritional value in terms of moisture, ash, protein, fat, carbohydrate, dietary fiber, energy value, mineral composition, antioxidant activity and tannins was compared. It is a novelty in the literature in relation to the particular analytes (e.g., minerals, tannins) and/or fruits (e.g., berberis, noni, haritaki). Especially rich in protein were Goji berry (13.3%), sea buckthorn (9.3%), noni (8.9%) and physalis (8.0%); in fat − sea buckthorn (11.2%); in dietary fiber (4.4–53.0%) − most of analyzed products. High antioxidant capacity was noticed for haritaki, berberis, rose hip, Goji berry, and physalis. An important source of minerals was 100 g of: noni (345 mg of Ca; 251 mg of Mg), rose hip (844 mg of Ca; 207 mg of Mg), juniper (564 mg of Ca), sea buckthorn (58 mg of Fe), berberis (24 mg of Fe) and haritaki (14 mg of Fe). The nutritionally attractive dried fruits have the potential for wider application in food formulations.

This paper explores the documentation of social and spatial transformation in the Walworth area, South London. Spatial narratives are the entry point for my exploration, where official and ‘unofficial’ representations of history are aligned to capture the nature of urban change. Looking at the city from street level provides a worldly view of social encounter and spaces that are expressive of how citizens experience and shape the city. A more distanced view of the city accessed from official data reveals different constructs. In overlaying near and far views and data and experience, correlations and contestations emerge. As a method of research, the narrative is the potential palimpsest, incorporating fragments of the immediate and historic without representing a comprehensive whole. In this paper Walworth is documented as a local and Inner City context where remnants and insertions are juxtaposed, where white working class culture and diverse ethnicities experience difference and change. A primary aim is to consider the diverse experiences of groups and individuals over time, through their relationship with their street, neighbourhood and city. In relating the Walworth area to London I use three spatial narratives to articulate the contemporary and historic relationship of people to place: the other side examines the physical discrimination between north and south London, the other half looks at distinctions of class and race and other histories explores the histories displaced from official accounts.
