К-1 и сахароза как источник звеньев фруктозы. Выход трансгликозилирования существенно зависит от концентрации акцептора, донора и фермента, а также от времени реакции. При массовом соотношении RebА к сахарозе 1: 1 степень трансфруктозилирования за 24 часа составила всего 5,4%, а при соотношении 1: 5 она достигает более 23%. Выявлено, что трансфруктозилирование протекает эффективнее в концентрированных растворах, чем выше общая концентрация сахарозы и RebaA, тем выше выход фруктозилированного RebA. Для определения влияния рН на трансфруктозилирование β-фруктофуранозидазу инкубировали с раствором 1% RebА и 10% сахарозы при 40 ° С в течение 15 часов при различных значениях рН. Также было обнаружено, что с увеличением количества фермента реакция ускоряется. Наиболее оптимальными были количества 50-100 единиц на 1 г сахарозы. Исследована реакция трансфруктозилирования стевиозида, а также показана органолептическая оценка фруктозилированных производных фруктозил-RebА, фруктозил-стевиозида и фруктозилрубузозида. Выделение и очистку фруктозилированного Reba осуществляли осаждением и очисткой этанолом на колонках, заполненных макропористой смолой Diaion HP-20. Полученный продукт обладает улучшенными сенсорными характеристиками и может быть использован в качестве низкокалорийного подсластителя.</p></abstract><trans-abstract xml:lang="en"><p>Rebaudioside A (RebaA) was subjected to β-2.6 transglycosylation with β-fructofuranosidase from Arthrobacter sp. K-1 and sucrose as a source of fructose units. The yield of transglycosylation depends signiﬁcantly on the concentration of the acceptor, the donor and the enzyme, as well as the reaction time. At the weight ratio of RebА to sucrose of 1: 1, the degree of transfructosylation in 24 hours was only 5.4%, while at a ratio of 1 : 5, it reaches to more than 23%. It was revealed that transfructosylation proceeds more efﬁciently in the concentrated solutions, the higher the total concentration of sucrose and RebaA, the greater the yield of fructosylated RebA. To determine the effect of рН on transfructosylation, β-fructofuranosidase was incubated with a solution of 1% RebА and 10% sucrose at 40°C for 15 hours at various pH values. It was also revealed that with an increase in the amount of the enzyme, the reaction accelerates. The most optimal were quantities of 50-100 units per 1 g of sucrose. The reaction of transfructosylation of stevioside is examined, and an organoleptic evaluation of fructosylated derivatives of fructosyl-RebА, fructosyl-stevioside and fructosyl-rubuzoside is also shown. Isolation and puriﬁcation of fructosylated Reba was carried out by ethanol precipitation and puriﬁcation on the columns ﬁlled with macroporous Diaion HP-20 resin. The resulting product is possessing improved sensory characteristics and can be used as low-calorie sweetener.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>transfructosylation</kwd><kwd>β-fructofuranosidase</kwd><kwd>cultivation of Arthrobacter sp.
