The Impact

Factor subsidies in a perfectly competitive setting are analysed. A very general model is used to derive expressions for the effect of a factor subsidy on the price and quantity of output and the two factor inputs. These expressions are differentiated to generate qualitative results for the impact of changes in the product-demand, production-function, and factor-supply parameters on the subsidy effects. A similar procedure is used to investigate the exchequer cost per job of general labour and capital subsidies in an industry with Cobb — Douglas technology. The analysis is relieved with illustrative simulations in which ‘representative’ parameter values are used.

The Impact

Food security is a critically important issue in China and can be enhanced by implementing subsidy policies. This paper employs a partial equilibrium model which takes into account the impact mechanism of subsidy policies to simulate the impact of current subsidy policies on grain supply and demand and on enhancing grain self-sufficiency in China. The simulation results suggest that subsidies can generally promote grain production, reduce consumption, increase imports, reduce exports and increase ending stocks. Subsidies may also result in increases in grain self-sufficiency rate and stock-to-use ratio, but the increases are relatively small, indicating that the subsidies lack efficiency. Given that subsidies constitutes only a very small share of farmers’ total income, and that significant scope remains for increasing subsidy levels in China, employing subsidy policies can help to enhance or at least maintain China’s grain self-sufficiency at a high level. Various measures should be implemented to improve the inefficiency of the current subsidy system, such as (1) combining different types of subsidies; (2) providing discriminatory subsidies to poor/rich farmers or developing/developed areas; and (3) increasing subsidy rates for wheat and corn.

The Impact

During processing of cereal-based food products, starch undergoes dramatic changes. The objective of this work was to evaluate the impact of food processing on the starch digestibility profile of cereal-based foods using advanced imaging techniques, and to determine the effect of preserving starch in its native, slowly digestible form on its in vivo metabolic fate. Four different food products using different processing technologies were evaluated: extruded products, rusks, soft-baked cakes, and rotary-molded biscuits. Imaging techniques (X-ray diffraction, micro-X-ray microtomography, and electronic microscopy) were used to investigate changes in slowly digestible starch (SDS) structure that occurred during these different food processing technologies. For in vivo evaluation, International Standards for glycemic index (GI) methodology were applied on 12 healthy subjects. Rotary molding preserved starch in its intact form and resulted in the highest SDS content (28 g/100 g) and a significantly lower glycemic and insulinemic response, while the three other technologies resulted in SDS contents below 3 g/100 g. These low SDS values were due to greater disruption of the starch structure, which translated to a shift from a crystalline structure to an amorphous one. Modulation of postprandial glycemia, through starch digestibility modulation, is a meaningful target for the prevention of metabolic diseases.

The Impact

The popularity of food products and medicinal plant materials containing hydrolysable tannins (HT) is nowadays rapidly increasing. Among various health effects attributable to the products of plant origin rich in gallotannins and/or ellagitannins the most often underlined is the beneficial influence on diseases possessing inflammatory background. Results of clinical, interventional and animal in vivo studies clearly indicate the antiinflammatory potential of HT-containing products, as well as pure ellagitannins and gallotannins. In recent years a great emphasis has been put on the consideration of metabolism and bioavailability of natural products during examination of their biological effects. Conducted in vivo and in vitro studies of polyphenols metabolism put a new light on this issue and indicate the gut microbiota to play a crucial role in the health effects following their oral administration. The aim of the review is to summarize the knowledge about HT-containing products’ phytochemistry and their anti-inflammatory effects together with discussion of the data about observed biological activities with regards to the current concepts on the HTs’ bioavailability and metabolism. Orally administered HT-containing products due to the limited bioavailability of ellagitannins and gallotannins can influence immune response at the level of gastrointestinal tract as well as express modulating effects on the gut microbiota composition. However, due to the chemical changes being a result of their transit through gastrointestinal tract, comprising of hydrolysis and gut microbiota metabolism, the activity of produced metabolites has to be taken into consideration. Studies regarding biological effects of the HTs’ metabolites, in particular urolithins, indicate their strong and structure-dependent anti-inflammatory activities, being observed at the concentrations, which fit the range of their established bioavailability. The impact of HTs on inflammatory processes has been well established on various in vivo and in vitro models, while influence of microbiota metabolites on silencing the immune response gives a new perspective on understanding anti-inflammatory effects attributed to HT containing products, especially their postulated effectiveness in inflammatory bowel diseases (IBD) and cardiovascular diseases.

The purpose of the article is to carry out an analytical assessing the impact of the COVID-19 pandemic on the level of food security in Ukraine. Research methods. The research was based on general scientific and economic methods, the creative heritage of the founders of economic science, publications of Ukrainian and foreign scientists on the impact of quarantine restrictions related to the spread of the COVID-19 pandemic on the level of food security of the country, regulatory legal acts, data from the State Statistics Service of Ukraine, electronic resources and other sources. The monographic approach is used to analyze the dynamics of the actual consumption of agri-food products and the level of food independence for individual agri-food products. Normative and positive approaches are used to highlight real risks and threats to food security. A number of techniques of abstract-logical tools made it possible to make a scientific and applied generalization of the material presented, to formulate intermediate and final conclusions and proposals. Research results. An analytical assessing the impact of the COVID-19 pandemic on the consumption of agri-food products and the level of food independence for individual agri-food products has been carried out. It has been proven that Ukraine produces enough food to ensure healthy nutrition for citizens. It has been determined that due to the low purchasing power of the population, groups of citizens with low incomes have limited access to essential agricultural and food products. In the medium and long term, there will be a shortage of food resources and global food inflation, the situation in agricultural markets will remain unstable, and trade will continue to develop under the influence of not only competition, but also political factors. Scientific novelty. The theoretical and methodological provisions, scientific, methodological and practical approaches to determining the factors of influence of quarantine measures and the spread of COVID-19 to the level of food security of the state have been substantiated. Assessing the impact of quarantine measures and the spread of COVID-19 on food security made it possible to identify the main risks of ensuring the country's food security. Practical significance. The applied aspects of the study can be taken into account in the formation of programs for the socio-economic development of the agri-food sector of Ukraine, which will increase the effectiveness of state initiatives aimed at ensuring food security of the state and increase the country's readiness for force majeure threats.
