Problems solved by technology

Existing scented teas have large flowers and rich petals, which are usually processed by high-temperature baking, and the flowers of macadamia nut flowers are small, and conventional high-temperature baking tends to make the flowers crispy, shattered when touched, difficult to shape, and long-term Baking can easily cause the fragrance of the flowers to be seriously lost. In addition, the conventional freeze-drying method has not been pretreated, and the volume of the water will increase during the process of freezing into ice. The macadamia flower corolla is small, and it is easy to deform and break
Therefore, the production method of conventional scented tea is not suitable for the production of macadamia scented tea, and there is no document reporting its processing method at present.
