Abstract:
The paper presents the results of researches on the use of antioxidants - ascorbic acid, citric acid and sulfur dioxide for the treatment of unpeeled apples, without seeds, cut plates at different thicknesses, different concentrations of solutions and treatment duration. It has been established that the most optimal concentration of SO2 solution is 0.075% at which the technological process can be organized and accumulates a minimum amount of SO2 in the dry product. The optimal parameters for SO2 solution treatment are: apple thickness - 6 mm; time of treatment - 8 min; concentration of the solution 0.075%; temperature of solution 23 ± 2 ° C.
