This article is devoted to the intensification of candied fruit production from mandarin secondary material resources. A new technological scheme for the production of candied tangerine fruits has been developed. In the technological scheme for the production of dietary candied mandarin peel from raw materials, we propose: instead of thermal processes, blanching in water, convective drying, blanching and drying in the field of infrared (IR) rays, instead of sugar - in the technological scheme we select low-calorie “saccharin” (aspartame). As a result of research, modes for blanching mandarin secondary material resources in the field of infrared rays were established, namely: Irradiation density P=0,35-0,40 kw/m2; distance between the material under study and the infrared ray generators Н=20 cm; Material thickness δ=9 cm; Duration of thermal irradiation τ =50-53 sec (95–98°C); residual moisture content of the semi-finished product is 73-75 %. The modes for drying mandarin secondary material resources in the field of infrared rays have been established, namely: P =0,35-0,40 kw/m2; Н =20 cm; δ =9 cm; τ =25-27 min (100–105°C); residual moisture content of the semi-finished product is 21–23 %. Thermal treatment of mandarin secondary material resources in the field of infrared rays is feasible and promising. The intensity of the process increases 5 times or more compared to the existing method, the quality of the product improves (0,5-0,6 points).
