Abstract. Assortment falsification and low quality of expensive imported food products contribute to the development of mistrust on the part of consumers and, thereby, decrease their sales volumes, which impedes the expansion of sales markets and profit from sales. The aim of the research was to study the assortment and quality of olive oil sold on the commodity market. The studies used generally accepted test methods: marketing, organoleptic, physico-chemical, statistical. Results. It has been established that the assortment of olive oils is represented by 24 names of products: mainly unrefined by the production method, of Spanish origin, in green glass bottles of 0.5 l and 0.25 l, with a price range of 1 liter from 479.9 rubles. (trademark “Altera”) up to 1220 rubles. (trademark “Borges”). The labeling of the samples taken for testing of unrefined olive oil Extra Virgin Olive Oil of the “Borges” and “Sitia” brands and the refined Olive oil of the “Fillippo Berio” trademark was complete and complies with the requirements of current technical regulations. Consumer labeling of „Olivesco“ brand squeezed oil needs to be corrected in the name and composition of the products. The quality of consumer packaging, sensory and physico-chemical (relative density, refractive index, color number, acidity, acid and peroxide numbers) indicators were within the Russian and international standards. The best example of Extra Virgin Olive Oil can be considered “Sitia” brand products, which have confirmed their status of Protected Appellation of Origin (PDO). The scientific novelty of the research is to identify the quality of oils for compliance with the requirements of the international regulatory document – CODEX STAN 33-1981, REV.2-2003, developed by the Codex Alimentarius and adopted by the FAO / WHO International Commission.
Abstract. Krupnova TG, Naumova NL, Rakova OV, Burmistrova OM, Burmistrov EA. 2021. Apple trees as a possible monitor and phytoremediator of urban and industrial areas in Chelyabinsk, Russian Federation. Biodiversitas 22: 2824-2828. Apple trees are cultivated worldwide and are the most widely grown fruit crops in the South Ural region. This study examines the suitability of apple trees for biomonitoring and phytoremediation. We collected the leaves and fruits of the apple (Malus domestica Borkh.) trees and the surrounding soil from three areas in Chelyabinsk, a typical Russian industrial city. The leaves, fruits and soils were analyzed for metal(loid) content (As, B, Cd, Co, Cr, Cu, Fe, Ga, In, Hg, Mn, Ni, Pb, Se, Sn, Sr, and Zn). The results were obtained using mass spectrometry with inductively coupled plasma (ICP-MS). We found a response in the apple tree defense system to the action of heavy metals in the synthesis of biologically active substances. The data gave information about the environmental state of soils collected in the zones of influence of metallurgical industrial enterprises. However, the trees did not assimilate or tolerate high concentrations of metal(loid)s in the leaves and they cannot be recommended for phytoremediation.
