2. Due to respiration, acidic substances are oxidized, reducing the sour taste; The synthesis and accumulation of aromatic substances increased, and the fruit had a special aromatic smell. Therefore, in the process of re-storage and transportation, it is necessary to create an environment with low temperature, proper ventilation and elimination of harmful gases.
3. Generally, the conditions of low temperature, high humidity and little oxygen are adopted to keep the fruit fresh and prolong the storage time. Therefore, low temperature can not only inhibit the respiration of fruits, but also reduce the activity of enzymes, thus delaying ripening and reducing nutrient consumption. Seabuckthorn fruit needs to be frozen for a long time.
4, humidity is also very important, the humidity is too small, the water in the fruit evaporates, and the surface of the fruit shrinks; But the humidity should not be too high, otherwise it is easy to rot and deteriorate. The relative humidity should be kept at 90%-95%.

Second, the effect of seabuckthorn fruit 1, seabuckthorn fruit has the effect of promoting blood circulation and removing blood stasis.
1. Seabuckthorn fruit contains total flavonoids, which can increase myocardial nutrient blood flow, improve myocardial microcirculation and reduce myocardial oxygen consumption. The effective rate is 90% for patients with angina pectoris, which can better improve myocardial blood supply and cardiac function.
2. Seabuckthorn fruit has the function of supplementing nutrition. Seabuckthorn fruit contains many nutrients needed by human body, such as total flavonoids of seabuckthorn. The total flavonoids of Hippophae rhamnoides can improve the serum complement level, enhance the function of macrophages, not only supplement nutrition, but also improve the body's disease resistance.
3. Seabuckthorn fruit has the effect of preventing cancer. Seabuckthorn fruit contains isorhamnetin, a variety of seabuckthorn glycosides, oleic acid, linolenic acid, sitosterol and so on. It can effectively block the synthesis of N- nitrosomorpholine, which is stronger than ascorbic acid with the same concentration.
4. Seabuckthorn fruit has the effect of protecting liver. Seabuckthorn fruit can reduce the content of malondialdehyde in liver, the activities of alanine aminotransferase and aspartate aminotransferase in serum, and play a role in protecting liver.
5, seabuckthorn fruit has the effect of promoting fluid production and quenching thirst. Seabuckthorn fruit contains a lot of vitamin C, carotene, citric acid, malic acid and so on. It can stimulate the secretion of parotid gland and supralingual gland, and play a role in promoting fluid production and quenching thirst.
