However, during the post-ripening process of passion fruit after picking, the respiratory metabolism of the fruit is accelerated, the decomposition rate of internal substances is increased, and the tissue structure is also rapidly disintegrated or disintegrated, making it difficult to store

Generally, the storage time of passion fruit is about 5 days, and the fruit begins to dry up, and the fruit basically rots in about 10 days. Therefore, passion fruit is not easy to transport and export, which seriously limits the development of passion fruit industry.
