    • No processo de fabricação do açúcar, as enzimas alfa-amilases de termoestabilidade intermediária podem resistir aos tratamentos térmicos empregados e continuarem ativas nas etapas posteriores do processo, acarretando em defeitos no produto final e prejuízos económicos. Para evitar tal tipo de problema, é proposto um método de detecção de atividade residual de alfa-amilase nas amostras de açúcar, baseado na viscosidade da amostra através do tempo de queda ("Falling Number"). O método se baseia no método original do "Falling Number", utilizado para medir atividade diastática em farinhas de trigo, e consiste nas seguintes etapas sequenciais: a. preparar uma amostra líquida do açúcar ou intermediários em teste na concentração de 50 a 600 g/L e com teor de sólidos solúveis variando de 5 a 60° Brix; b. adicionar a amostra liquida de açúcar ou intermediários obtida na etapa (a) em um recipiente contendo uma ou mais fonte de amido, com 1,5 g a 10 g de amido, podendo adicionar cálcio bivalente na concentração de 30 a 100 ppm em relação ao teor de amido; c. homogeneizar a solução obtida na etapa (b); d. aquecer a solução obtida na etapa (c) a temperatura de 60°C a 100° C, ao mesmo tempo em que dita solução é agitada com uma haste até sua gelatinização, que a viscosidade obtida varia entre 400 e 600 cP; e. soltar a haste no início do recipiente; f. verificar o tempo de queda da haste na solução gelificada, ao longo do comprimento total do recipiente; g. comparar o tempo de queda obtido na etapa (f) com o tempo de queda de uma amostra de açúcar sem alfa-amilase (amostra controle).
    • 在制造糖的过程中,中间热稳定性的α-淀粉酶可以抵抗所使用的热处理,并且在随后的工艺步骤中继续有效,导致最终产品的缺陷和经济损失。 为了避免这种类型的问题,提出了一种通过基于样品粘度的下降数来检测糖样品中残留α-淀粉酶活性的方法。 该方法基于原始的Falling Number方法,用于测量面粉中的水分活度,并由以下顺序步骤组成:a。 制备浓度为50-600g / L的糖或中间体的液体样品,其可溶性固体含量为5-60°白利糖度; 湾 将步骤(a)中制备的糖或中间体的液体样品加入到含有一种或多种淀粉源的容器中,加入1.5-10g淀粉,任选地加入浓度为30-100ppm的二价钙相对于淀粉含量 ; C。 均化步骤(b)中产生的溶液; 天。 将步骤(c)中制备的溶液加热到60-100℃的温度,同时使用棒搅拌所述溶液直到发生凝胶化,并且获得从400-600cP变化的粘度; 即 从容器的顶部落下杆; F。 检查棒在容器的整个长度上通过糊化溶液的时间; G。 将步骤(f)中获得的下降数与不含α-淀粉酶的糖样品(对照样品)的下降数进行比较。
