Trial production of "Rue Tea" from Satsuma Flower
Mandarin flower contains fructose, glucose and other sugars that help digestion and promote health; phosphorus that can excite the nerve; a variety of vitamins that have the effect of anti-capillary brittleness; a large amount of rutin and aromatic oil which can soothe the liver and purge the lungs, smooth qi and resolve phlegm, and contain starch and so on. Nutrition is very rich.
In the Tangshili orange orchard in the two cities of Shaodong County, we saw that nearly 100000 young Wenzhou mandarins were picked and wasted. After repeated trial production, we made some "rue tea". "rue tea" is easy to make. Take 9 parts of tea and 1 part of mandarin flowers, stir-fry them, knead them and then dry them. Another method is to dry the mandarin flowers in the sun, and then mix them with tea leaves and dry them. The aroma of the former method is uniform, and the latter can be mixed with tea at any time.
According to the experiment, the best ratio of flower to tea is 1 ∶ 9. If there are too many flowers, the fragrance of tea will be diluted; if there are too few flowers, the fragrance is not good. When picking, the budding flower is the best, the aroma is strong, and it is not easy to separate from the petals when kneading.

Fresh-keeping and Storage Technology of New Tea
● air-filled nitrogen fresh-keeping is to use nitrogen to replace the air in the bag to prevent the oxidation of tea, so as to achieve aging and deterioration of tea. Green tea was packed with nitrogen in aluminum foil bags. After 6 months of storage, the vitamin C content could be kept above 96%. Nitrogen-filled packaging in the inflating process must pay attention to the firmness of the bag seal, to prevent the occurrence of insufficient nitrogen or air leakage. Before packing with nitrogen, first remove the air from the bag to form a vacuum, and then fill it with nitrogen.
