Abstract

The invention relates to a production method of a dried blueberry tea fruit. The production method is characterized by taking fresh blueberry fruits or frozen blueberry fruits as main materials and including the working procedures of selection, cleaning, blanching, color protection, sugar making, tea soaking, drying and the like, wherein the combined actions of citric acid and ascorbic acid are adopted in color protection, once cooking is adopted in sugar making, then using infused tea for soaking and finally conducting successive temperature rising for drying, thus obtaining the finished product of the dried blueberry tea fruit. The finished product is characterized by being sweet and sour and tender in pulp, and integrating tea flavor with blueberry flavor. The production method of a dried blueberry tea fruit is applicable to not only fresh blueberries but also frozen blueberries; and a sulfur-free technology is adopted in the production process, therefore the nutrients and the natural flavor of the blueberry fruits are kept to the maximum, in addition, the dried blueberry tea fruit integrates the nutrients and the health care function of tea.

Description

(1) Technical field: [0001] The invention relates to a method for preparing dried blueberry tea and belongs to the technical field of food processing. (two) background technology: [0002] Blueberry, scientific name bilberry, also known as Dusi, Dushi persimmon, Dusi vaccinium, the fruit is a berry, the edible rate is 100%, and it is sweet and sour. In my country, it is mainly produced in the forest areas of the Greater and Lesser Khingan Mountains in Heilongjiang Province, especially in the central part of the Greater Khingan Mountains. It is a pure wild species. Blueberry fruit contains a lot of anthocyanins, which can protect eye health, prevent vision damage, benefit the retina, delay memory loss and prevent heart disease. In addition to conventional sugar, acid and Vc, blueberry fruit is also rich in VE, VA, VB, SOD, arbutin, protein, dietary fiber and rich in K, Fe, Zn, Ca and other mineral elements. Therefore, blueberry fruit also has the functions of preventing bra...
