    • It is an object of the present invention to provide a manufacturing process of carrot juice capable of obtaining, with high yield, carrot juice having a high-quality and stable characteristic free from occurrence of cohesion with less fishiness. To this end, the present invention comprises, first, peeling washed raw carrot, carrying out enzyme deactivation processing within one day, preferably, within 12 hours after peeling, and second, completely deactivating pectin esterase activity of carrot and carrying out enzyme deactivation processing so that a residual rate of pectinase activity is less than 60%. Such an enzyme deactivation processing may be done by blanching carrot till an internal temperature reaches 70 to 80° C. in water at 70 to 80° C., or blanching carrot till an internal temperature reaches 60 to 70° C. in 0.02M to 0.05M citric acid solution at 60 to 70° C., or processing carrot with supercritical carbonic acid gas by a microbubble SC—CO2 method. The carrot subjected to the enzyme deactivation processing was crushed similarly to normal vegetable juice or fruit juice and squeezed, and the obtained squeezed juice is adjusted to an acid region or to about pH 4.2, for example, such as citric acid solution, after which it is sterilized and filled into a container to serve as the carrot juice.
    • 本发明的目的是提供一种胡萝卜汁的制造方法,其能够以高产率获得具有高质量且稳定的特征的胡萝卜汁,而不会发生内聚性较差的腥味。 为此,本发明首先包括洗涤的生胡萝卜,在一天内,优选在剥离后12小时内进行酶失活处理,其次,完全失活胡萝卜素的果胶酯酶活性并进行酶失活处理 果胶酶活性的残留率小于60%。 这样的酶失活处理可以通过将胡萝卜漂洗直到内部温度在70〜80℃的水中达到70〜80℃,或者将胡萝卜漂白至内部温度达到60〜70℃,在0.02M〜 在60〜70℃下加入0.05M柠檬酸溶液,或用微泡SC-CO2法加工具有超临界碳酸气体的胡萝卜。 将进行酶失活处理的胡萝卜与普通蔬菜汁或果汁类似地粉碎并挤压,将得到的榨汁调节至酸性区域或约pH 4.2,例如柠檬酸溶液,之后将其 将其灭菌并装入容器中作为胡萝卜汁。
