How do I keep the coffee beans?

Coffee should be kept in a dry, cool place. It may absorb moisture and oxidize in the refrigerator. Beans that have been baked can be kept sealed at room temperature for 14 days, can be well preserved, can be extended for a few days, and can be stored in refrigerator or vacuum for 30 days. But the coffee in the refrigerator can only be thawed once, because when the beans or powder are taken out of the refrigerator, the temperature will rise rapidly, causing the surface of the coffee to condense water vapor and oxygen, which is why a lot of coffee should not be put in the refrigerator.

Coffee beans are damp and moldy to produce very tenacious ochratoxin.

Ochratoxin can be divided into A, B and C, among which ochratoxin An is the most toxic. According to the regulations of the Food and Drug Administration, the limit of ochratoxin An is less than 5 ppb. This standard is fully in line with the International Codex Alimentarius Commission (Codex), the European Union and China. This is mainly because most of Taiwan's coffee beans are imported. If the FDA conducts border inspection and finds that ochratoxin An exceeds the standard, the import will be stopped immediately.

Professor Zhao Mingwei said that these conditions for the growth of Aspergillus ochre are actually quite easy to achieve in Taiwan. As long as the water activity is more than 0.8 and there is enough air, spores will be produced, which will be widely distributed in the soil and air. Ochratoxin will grow and produce ochratoxin, so how to ensure transportation, storage and sale of coffee beans during the process from import to sale. It is very important to use vacuum package to maintain the degree of dryness and prevent the growth of Aspergillus ochre.

For the sake of everyone's health, we should protect the beans.
