Problems solved by technology

However, the above-mentioned blueberries need to be spray-dried at a high temperature of 130-150°C, which will easily inactivate the active components of proteases in the blueberries. At the same time, the prepared blueberry solid beverage has a high water content, and is produced under normal conditions, so the storage time is short.

Abstract

The invention relates to the field of food, and particularly discloses a blueberry solid drink and a preparation method thereof. The blueberry solid drink comprises blueberry powdered juice, inulin and fructo-oligose, has the functions of preventing cranial nerve aging, protecting the eyesight, strengthening the heart, preventing cancer, softening blood vessels, enhancing human body immunity and the like, and meanwhile has the effects of controlling blood fat, reducing blood glucose and the like. The preparation method of the blueberry solid drink comprises the steps that the blueberry powdered juice, the inulin and the fructo-oligose are mixed and dried at 50 DEG C to 60 DEG C till moisture is smaller than five percent, and subpackaging and packaging are carried out. Compared with the prior art, the whole process of the preparation method of the blueberry solid drink is carried out below 80 DEG C, the effective components of blueberries can be kept well, the nutritive value of the blueberry solid drink is improved, the prepared blueberry solid drink is small in carried bacterium quantity and low in moisture content, bacteria are not likely to breed, the toxin components are low, the storage period is long, the drink can be added to milk, coffee and other liquid food when eaten, and convenience and fastness are achieved.

Description

technical field [0001] The invention relates to the field of food, in particular to a blueberry drink and a preparation method thereof, in particular to a blueberry solid drink and a preparation method thereof.
