    • A method for controlling the isomerization of (−)-epicatechin to (−)-catechin in an epicatechin-containing product, preferably an edible product, which method comprises the step of heating the product at a temperature of up to about 190° C. and at a pH of up to about 8. A method for controlling the isomerization of (+)-catechin to (+)-epicatechin in a catechin-containing product, preferably an edible product, which method comprises the step of heating the product, at a temperature of up to about 190° C. and at a pH of up to about 8. Preferably, the temperature is from about 72° C. to about 125° C., the pH is from about 4 to about 7, and the time is at least about 15 seconds. Under either method, the isomerization may be carried out in an open food processor in a reduced oxygen atmosphere or in a closed food processor. The edible product may be pasteurized, boiled or sterilized during the isomerization. The isomerization is minimized by lowering the heating temperature, by lowering the pH, and/or by lowering the heating time. Conversely, the isomerization is maximized by increasing the heating temperature, by increasing the pH, and/or by increasing the heating time. The edible product may contain or be a fruit product, a vegetable product, a cereal product, a bean product, a nut product, or a spice product.
    • 用于控制含表儿茶素的产品( - ) - 表儿茶素至( - ) - 儿茶素异构化的方法,优选食用产品,该方法包括在高至约190℃的温度下加热产物的步骤。 并且在高达约8的pH下。一种用于控制含儿儿茶素产品中(+) - 儿茶素至(+) - 表儿茶素异构化的方法,优选食用产品,该方法包括加热产物的步骤, 在高达约190℃的温度下,pH最高达约8.优选地,温度为约72℃至约125℃,pH为约4至约7,并且 时间至少约15秒。 在任一方法下,异构化可以在开放的食品加工机中在还原氧气氛中或封闭的食品加工机中进行。 在异构化过程中,可食用产品可以进行巴氏杀菌,煮沸或灭菌。 通过降低加热温度,降低pH和/或降低加热时间来使异构化最小化。 相反,通过增加加热温度,通过增加pH和/或通过增加加热时间来使异构化最大化。 可食用产品可以含有水果产品,蔬菜制品,谷类食品,豆制品,坚果制品或香料制品。
