When we consider the issue of optimizing human diet, we should pay special attention to the use of non-traditional raw materials. Particular attention should be paid to the use of spelt in the cooking of such dishes as cereals. The quality level of such dishes is determined by the development of a control system for their production. Quality control of such dishes should be organized at all stages of the life cycle of the proposed dishes from spelt.

This paper presents the research results on the technologies developed for welding polyethylene pipes, which allow welding at ambient temperatures below the standard ones without temporary heated shelters. Two types of welding were considered: with a heated tool butt (butt) and an embedded heating element (electrofusion). The results of short-term and long-term tests of welded butt and socket joints show the effectiveness of the proposed technologies for the operational welding of polyethylene pipes for gas pipelines at low ambient temperatures.
