The main reason may be that the ingredients of Chinese herbal medicines used in some preservatives are complex, and the content and mechanism of active ingredients in them are not yet clear. The problem is not easy to solve. Some Chinese herbal medicines still have a special smell when used in large doses, which may not be accepted by the public; secondly, the extraction and mass production of active ingredients used in Chinese herbal medicines for preservatives do not yet have industrial conditions.

Background technique [0002] Guava ( Psidium guajava Linn. ) is an evergreen shrub or small tree of the family Myrtaceae Guava, native to tropical America, and is a fruit tree widely cultivated in tropical and subtropical regions of the world today. The respiration change of guava fruit after harvesting is of a climax type, and the occurrence time of the climax period has nothing to do with the maturity at the time of harvest. 2 and ethylene transition peaks, which is one of the reasons why guava is difficult to store and keep fresh. Its skin is fragile and thin, and it is very easy to be bruised and infected by viruses during picking and transportation, and it will rot. The shelf life at room temperature is only 2 to 7 days. When stored below 10 ℃, symptoms of chilling injury will appear. In addition, the dry water of guava fruit is severe after harvesting, the hardnes...
