Abstract

The invention relates to lotus seed oolong milk tea with a low GI value and a preparation method of the tea. The preparation method of the lotus seed oolong milk tea with the low GI value comprises the following steps of preparing acidic lotus seed pulp, performing microwave-ultrasonic treatment on the acidic lotus seed pulp, preparing resistant dextrin lotus seed powder, and preparing the lotus seed oolong milk tea with the low GI value. An organic acid and microwave-ultrasonic wave combined process is used for treating lotus seed pulp, conversion of lotus seed digestible starch into water-soluble resistant dextrin is promoted, the ratio of the resistant dextrin in the lotus seed raw material is remarkably increased, the activity of amylase is inhibited by adding oolong tea extract, and the GI value is remarkably reduced under the synergistic effect. The preparation process of the lotus seed oolong milk tea with the low GI value is simple and convenient; the product in the form of solid powder is convenient to store and carry, the nutritional ingredients and fragrance of lotus seeds and oolong tea are reserved, the requirements of nutrition and health at met, the adverse effect ofa large amount of digestible starch in the traditional lotus seed juice on the blood sugar level in the body is overcome, and the lotus seed oolong milk tea is suitable for consumers needing to control the blood sugar level to drink.

Description
