According to Baidu Health, durian can't be eaten after three days of cracking. Cracks in durian indicate that durian is ripe, tastes sweet and can generally be preserved for one day. If it doesn't crack, it can be stored in the refrigerator for about three days. Three days after durian cracks, the pulp inside will combine with bacteria in the air to produce a chemical reaction, leading to bacterial growth, dark color and toxic substances, which are harmful to human body after eating, causing adverse reactions such as abdominal pain and diarrhea. Durian pulp will produce gas when it comes into contact with air, which will decompose in durian pulp and release hydrogen sulfide harmful to human body. Durian has a high sugar content. Durian will produce a lot of aflatoxin if it is left in a low temperature environment for a long time. If these substances are not removed in time, it will accelerate the deterioration of pulp and lead to durian rot and deterioration. When storing durian, it is recommended to keep the air circulating and dry, so as to avoid durian mildew caused by humid environment.
