Nowadays the supply of cephalopods to coastal enterprises has decreased due to restrictions on fishing for the main producing countries. Increased conservation of dwindling cephalopod stocks and premature closure of fishing seasons are driving up the price of high-value seafood such as squid and octopus. In addition, the decline in supplies is also due to an unstable epidemiological situation and a reduction in labor resources at the production facilities. Therefore, in the current conditions, a deeper processing of raw materials is highly necessary, obtaining high- quality products, although in smaller quantities but at the same time not requiring subsequent processing. Deep processing of raw materials should be carried out using energy- and resource-saving technologies. Their effective implementation should be based on knowledge of generalized patterns of processes. The processes of food materials dehydration in technological lines in most cases fall into the most energy- and resource-intensive categories. It is noted that the dehydration of cephalopods proceeds somewhat differently than the dehydration of fish raw materials. The dependencies of critical moisture on the initial moisture content (Fig. 6) in fish raw materials and cephalopods based on equations (1-3) are analyzed. The dependencies presented in Fig. 6 demonstrate the nature of the relationship between the initial and critical humidity during the dehydration of fish raw materials and cephalopods. Fig. 6 demonstrates the nature of the connection between the initial moisture and the critical one during the dehydration of fish raw materials and cephalopods. The graphs show that cephalopods have the period of constant dehydration rate significantly longer compared with fish. The end of this period for fish raw materials corresponds to the achievement of the first critical moisture rnki and for cephalopods - the only critical moisture in the dehydration process a ki. For example, with the same initial moisture content of raw materials of 400 %, t . = T 464
