中文摘要: 以红萝卜和西红柿为原料,研究复合蔬菜汁饮料的加工工艺条件。结果表明:红萝卜和西红柿的最佳破碎方式 均为 85 ℃ 1 min,果胶酶处理分别为添加量 0.14 %、50 ℃酶解 50 min 和添加量 0.10 %、50 ℃酶解 40 min,可显著提高红 萝卜出汁率和西红柿出汁率(P<0.05)。在红萝卜汁与西红柿汁混合比例为 1 ∶ 3(体积比)、添加 6 %的白砂糖和 0.1 %的 柠檬酸、添加 0.1 %黄原胶和 0.1 %海藻酸钠的复合稳定剂时,可获得具有较好品质的复合蔬菜汁饮料。
Abstract:The processing-technology conditions of compound vegetable beverage with red radish and tomato as raw materials were studied. The results showed that: the best way of red radish and tomato juicing was 85 ℃ 1 min, the radish juice yield could be improved distinctly by adding 0.14 % pectinase, hydrolyzing 50 min at 50 ℃ (P<0.05), the tomato juice yield could be improved by adding 0.10 % pectinase, hydrolyzing 40 min at 50 ℃(P<0.05). In the conditions which the optimal proportion of red radish and tomato juice content was 1 ∶ 3 (v/v), 6 %sugar, 0.1 %lemon acid, 0.1 %sodium alginate and 0.1 %xanthan gum added, the compound veg- etable drinks which had better sensory evaluation were obtained.
