“…In our study, honey from the Czech Republic was used, which is typically affected by large-scale farming [ 28 ]. In comparison, honey can be collected also from country with fragmented agricultural activity [ 65 ], from national parks [ 66 , 67 ] or other region with high floral diversity, where typically one family is represented by multiple species, wild cultivars and endemism. These types of honey are also typical by high content of pollen with similar shape, polar and equatorial length, P/E, and pollen ornamentation.…”

Melissopalynology is an important analytical method to identify botanical origin of honey. Pollen grain recognition is commonly performed by visual inspection by a trained person. An alternative method for visual inspection is automated pollen analysis based on the image analysis technique. Image analysis transfers visual information to mathematical descriptions. In this work, the suitability of three microscopic techniques for automatic analysis of pollen grains was studied. 2D and 3D morphological characteristics, textural and colour features, and extended depth of focus characteristics were used for the pollen discrimination. In this study, 7 botanical taxa and a total of 2482 pollen grains were evaluated. The highest correct classification rate of 93.05% was achieved using the phase contrast microscopy, followed by the dark field microscopy reaching 91.02%, and finally by the light field microscopy reaching 88.88%. The most significant discriminant characteristics were morphological (2D and 3D) and colour characteristics. Our results confirm the potential of using automatic pollen analysis to discriminate pollen taxa in honey. This work provides the basis for further research where the taxa dataset will be increased, and new descriptors will be studied.

“…Farming is concentrated in more fertile areas. The agriculturally marginal areas include grasslands in the areas of higher altitudes, with steeper gradient and worse soil quality [54]. Four major forest types, corresponding to phytosociological associations, can be distinguished in the Czech Republic: Hercynian, widespread in the Bohemian Massif (Melampyro nemorosi-Carpinetum); Pannonian, confined to southern Moravia (Primulo veris-Carpinetum); Carpathian, common in eastern and central Moravia (Tilio cordatae-Carpinetum); and wet habitat type, occurring mainly on soft bedrocks in eastern Bohemia, northern Moravia and Silesia (Stellario holosteae-Carpinetum) [55].…”

“…Neighbouring countries also have a similar climatic and botanical character, but differ in their agricultural activity. Agricultural structure in Poland, Austria, and Germany is more fragmented [54]. This has increased biodiversity in these regions.…”

Physico-Chemical and Melissopalynological Characterization of Czech Honey

Geographical and botanical origin of honeys can be characterized on the basis of physico-chemical composition, sensory properties and on the basis of melissopalynological analysis. No comprehensive description of the characteristics of Czech honey has been published so far. This study provides insights that are important for correct classification. The study analysed 317 samples of authentic honey from randomly selected localities. Due to the diversity of the landscape, the typical honey of the region is blend honey with a predominance of blossom honey. According to the pollen profile and electric conductivity, the honeys were sorted into the following: Brassica honey (BH), Floral honey (FH), Fruit tree honey (PH), Honeydew (HD), Lime tree honey (LH), Robinia pseudoacacia honey (RH), and Trifolium honey (TH). Physico-chemical properties, including higher carbohydrates, were determined for the honeys and their pollen profiles were examined. The physico-chemical properties and pollen profile are partially in compliance with the description of European monofloral honeys, except for RH and TH. Although they had the highest proportion of acacia pollen, amounting to >10% of all the Czech honeys, these RH honeys differ from the European standard, so they cannot be considered acacia honey. Further, PH honeys and FH polyfloral honeys were described. Most honeys contained a significant proportion of rapeseed pollen, which is one of the common agricultural crops grown in the Czech Republic. All the analysed honeys met the parameters defined by the legislation. Due to direct on-site sampling, honeys were characterized by a low 5-(hydroxymethyl)furfural (HMF) content (3.0 mg/kg) and high diastase activity (24.4 DN). Honeydew honeys had the highest proportion of higher carbohydrates, primarily of Melezitose (4.8 g/100 g) and Trehalose (1.3 g/100 g). The presence of higher carbohydrates was also confirmed in LH for Maltose (4.6 g/100 g) and Turanose (2.4 g/100 g).

“…Agricultural policy represents one of the methods of state intervention in market mechanisms, which is practically observed in various forms all over the world [50,51]. Nowadays, it results more from the need to counteract undesirable processes related to excessive concentration and land use for The production of feed crops in Ukraine in 2018 took only 6.6% of the agricultural land area: technical crops-33.4%; cereal and grain legume crops-53.6%.…”

The social and economic conditions of all market participants are incentives and constraining factors influencing the levels of food, social, economic and ecologic security. The purpose of the article lies in the presentation of the author’s concept of the social and economic conditions where the transformation of economic relations between agrofood market participants is happening—in particular, the livestock products market of Ukraine—and the assessment of the state of food security of the country, as well as a comparison, by the same criteria, of the conditions of agrofood market participants in Ukraine and in four European countries: Germany, France, Italy, and Poland. This research was based on the application of empirical knowledge methods: observation, comparison, description, measurement, statistic methods, etc. So far, the participant functioning conditions in the agricultural market in Ukraine are unfavorable for the sustainable development of agriculture, especially the livestock industry. The debt burden of external creditors is growing, the amount of direct investments from the countries of the world decreases, and the growth of capital investment in terms of calculation per one employee is slowing down. The food security of Ukraine is unstable. The “market” itself is not capable of remedying all the negative phenomena. Therefore, it is necessary to apply the weighted power of the state.
