Abstract

Изобретение относится к биотехнологии.Цель изобретения - упрощение процесса за счет минимизации образования побочных продуктов.Способ предусматривает хлорирование производного сахарозы, замещенного в положении 6, с введением атомов хлора в положение 4,1' и 6' сахарозы и последующее удаление 6-заместителя. В качестве 6-замещенного производного сахарозы используют рафинозу. Удадение 6-заместителя осуществляют путем ферментативного гидролиза 1-15% раствора О-α-Д-6-хлор-6-дезоксигалактопиранозил-(1-6)-α-Д-4-хлор-4-дезоксигалактопиранозил-(1-2)-β-Д-1,6-дихлор-1,6-дидезоксифруктофуранозида в водной системе или в гидрофобном растворителе с использованием - галактозидазы из Mortierella vinacea или Circinella muscat проявляющей степень гидролиза от 1,6 до 4,3 мг сукралозы га 1г сухого клеточного остатка в 1ч при 30-60°С до достижения 50-70%-ной конверсии. Растворитель представляет собой метилизобутилкетон, этилацетат или н-бутанол.
