Impacts of COVID-19 on the food supply chain for arable crops in Latvia
Upite, Ilze | Bite, Dina | Pilvere, Irina | Nipers, Aleksejs
The COVID-19 pandemic has caused unprecedented stress to food supply chains, pointing to weaknesses in the labour, processing, transport and logistics spheres, as well as significant changes in demand. Food supply chains have shown considerable resilience in the face of such stress. Monitoring of the food sector during the COVID-19 pandemic indicates that the effects of COVID-19 on food supply, demand and access are interlinked processes and have a complex impact on food systems. In addition, high-value food supply chains in developed countries are even more complex, so countries need to respond quickly to restore them and also develop mechanisms that balance business and public interests and protect farmers and food business workers during future potential pandemic crises. The research aims to identify the main demand and supply side factors that affect the resilience of local and global food supply chains during the COVID-19 crisis, as well as assess the resilience of the supply chain for arable crops during the COVID-19 crisis in Latvia, identifying the main risk factors. The research found that arable crop farmers were relatively less affected by the COVID-19 crisis than other agricultural employees. The impact of the crisis was larger on the crop processing industry than on the other industries, and the main risk factors related to changes in demand and the industry’s dependence on imported raw materials and the successful operation of export markets. Based on an in-depth risk analysis, the research developed recommendations for policy makers and actors in the agri-food chain that would improve the resilience of local (domestic) participants of the arable crop food supply chain in Latvia.

2022
Lignicka, Ilva | Galoburda, Ruta
To meet the rising consumer demand for higher nutrition foods and to increase flake nutritional value and functionality, it is possible to combine cereals with pulses. For consumers, one of the most important quality parameters, along with appearance and taste, is texture. To produce the appropriate quality of flakes, the knowledge about the relationship between chemical composition, processing parameters, and texture is necessary. The aim of this study was to characterise the role of cereal and pulse constituents and processing technologies in flake texture development, which could be used in flake production for achieving the appropriate hardness and crunchiness of new products. The monographic method was used to characterise the constituent and processing technology`s role in cereal and pulse flake texture development. Information published from 2003 till 2022, in total 77 full text research articles, books and databases were analysed and summarised. Data analysed show if pulse and cereal nutritional information, mineral and vitamin content is known, it is possible to combine different cereals and pulses to provide a specific nutrient composition in the developed products. The main change in high starch products is a specific gelatinization and retrogradation behaviour of starch. Constituents such as lipids and proteins as well as processing technology and parameters, can significantly modify the properties and functionality of starch. Proteins can encapsulate starch granules, inhibit starch digestion and gelatinization, reduce starch structural order, and inhibit starch retrogradation.
