Toona sinensis bud is a spring food that many friends like. The taste is fresh and tender, and it has a special aroma. I like it too. My favorite dish is Toona sinensis scrambled eggs. Toona sinensis buds are common in rural areas in spring, but rare in cities. In spring, many friends go to the countryside to pick Chinese toon buds. Last spring, the fresh Toona sinensis buds in the supermarket were bought for tens of dollars a catty, which also surprised me. Although this kind of Toona sinensis bud is delicious, it has a short storage time. If you can't eat it in time after picking, it will age in a few days, and the nitrate content in the aging Toona sinensis buds is high, which is not good for your health. There are many ways to prolong the preservation time of Toona sinensis buds. The preservation of Toona sinensis buds can be divided into short-term preservation and long-term preservation.

There are many short-term preservation methods of Toona sinensis buds, which can generally be preserved for about one to two weeks. Fresh Toona sinensis buds can be cleaned, trimmed at the bottom, then put upright in clean water to make Toona sinensis buds fully absorb water for 24 hours, and then put into a fresh-keeping box, which can prolong the fresh-keeping time of Toona sinensis buds by about one week. Secondly, in order to avoid the aging of Toona sinensis buds, Toona sinensis buds can be preserved after blanching, and the operation is very simple. Wash fresh Toona sinensis buds, blanch them in boiling water, drain them in cold water, put them in fresh-keeping bags, and then put them in the refrigerator for refrigeration. The temperature of the cold storage is controlled at 0- 1 degree, which can generally be kept for about two weeks.

There are many ways to preserve it for a long time. Toona sinensis buds can be made into dried vegetables, pickled vegetables or frozen. Let's talk about the method of making dried vegetables first. Put fresh Toona sinensis buds in boiling water for about 3 minutes, then take them out and put them in cold water to keep the color of Toona sinensis buds. After cooling water, dry it and store it in a ventilated place for about 1 year. Pickling is also very simple. After washing the fresh Toona sinensis buds, dry the surface moisture, evenly sprinkle fine salt on the leaves, put the treated Toona sinensis buds into a sealable jar, and add appropriate amount of liquor, vinegar, sugar, etc. Sealed and stored in a cool place, it can be eaten at any time or stored for a long time.

There are several short-term preservation methods: one is direct preservation. Flatten the bottom of the newly picked Toona sinensis bud, soak it in clear water for one day, drain the water, put it in a fresh-keeping box, and keep it in a cool and ventilated place for about a week. In addition, the newly picked Toona sinensis buds can be placed in a clean fresh-keeping bag and in a refrigerator at 0 ~ 65438 0℃. This method can be preserved for about 3 weeks. These two short-term preservation methods require small packages to avoid thermal deterioration when stacked together. Long-term preservation is mainly frozen curing. First, freeze preservation, that is, put the Toona sinensis buds in boiling water for about 1 min until the leaves turn green, then put them in cold water, cool them, drain the water, put them in fresh-keeping bags, and put them in a refrigerator at-10℃.
