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
