The systematic effectiveness of business processes at food industry enterprises is visualized. Proposals for improving the security conditions of food industry enterprises during the war are proposed. Obviously, the business sector of any industry, including the food industry, is dependent on the military situation in our country. The state policy can currently provide some funding for the social sphere. However, the economic and technological decline of the food industry will necessarily lead to a food crisis, shortages, and hunger. In order to avoid this, food industry enterprises in the occupied territories can receive state assistance and support during the transportation of technological capacities to the western regions of Ukraine. Conditions for these enterprises to provide preferential or free transfer to places of temporary deployment should be created, temporary production facilities and qualified personnel should be offered, etc. The Verkhovna Rada of Ukraine adopted a draft law on the peculiarities of taxation and reporting during martial law, which in particular provides the possibility of reporting documentation within 90 days after the completion or termination of martial law; absence of scheduled inspections; extension of licenses for food industry enterprises; zero quotas for the export of food products, such as rye, oats, buckwheat, millet, sugar, and salt; provision of loans for agricultural activities (sowing).
