Abstract

The invention provides a preparation method of bletilla striata flower tea. The preparation method comprises the following steps: step 1, pretreating flowers, picking unopened buds of fresh purple-flower bletilla striata, cleaning the buds with clear water, and removing residual water on the flowers; step 2, performing high-temperature color protection to inactivate the endoprotease of the flowers to prevent the petals from browning; step 3, filtering water, namely cooling the inactivated water in water at the temperature of below 20 DEG C, and transferring the cooled water into dry gauze or a filter screen to filter water; step 4, hot air drying is adopted, the bletilla striata flowers subjected to water filtering are placed in a bamboo steamer, steamer paper or aluminum foil is cushioned on the lower portion, and the temperature of hot air is adjusted to 40-60 DEG C; and step 5, storing: packaging the scented tea with a food-grade plastic packaging bag, and adding a drying agent into the bag. The method has the advantages that the nutritional ingredients, appearance and color of the bletilla striata flowers are effectively reserved, so that the bletilla striata flowers can be really used as health-care tea diet.

Description
