Does excessive fermentation of yogurt affect your health?

Excessive fermentation will increase the acidity of the yogurt, while the activity of the lactic acid bacteria will decrease, and there will be some changes in the taste, but it will not cause harm to health. However, people with bad stomachs should not drink yogurt after a long time.

Mr. Zhang: My family has been ordering bottled yogurt for drinking. On July 6, my child took a sip of yogurt and said that there was a strange smell. I quickly tested it and found that there was a strange smell. I have been diarrhea since then. And then my stomach is very uncomfortable. I called the manufacturer, the manufacturer said that the taste may be caused by excessive fermentation, and then sent a staff member to my home to take the yogurt back for testing. On the 12th, the manufacturer replied to me that after testing, there was no problem with yogurt. I would like to ask, what is the concept of over-fermentation of yogurt? Will it cause harm to the body after drinking?

Reporter: The reporter contacted Li, the person in charge of the Zhonghe Dairy Quality Control Department. The other party said that the strange smell that Mr. Zhang said should be caused by the excessive fermentation of yogurt. For yogurt, the state stipulates that the acidity cannot be lower than 70°, but there is no upper limit. “Because the yogurt we produce is mainly for the consumers in the province, the taste of Shanxi people is more acidic, so the acidity of our yogurt will generally reach 90°, but this is when the refrigerating temperature can't exceed 6°C. If the yogurt is When placed at room temperature, especially in the summer, plus shaking, its acidity will increase, and the taste will change. People with bad stomachs may not be able to stand the acidity and feel uncomfortable." He also said that yogurt Excessive fermentation will not harm the human body and can be safely consumed. At the same time, Manager Li suggested that the public should buy the yogurt in the summer, and then put it into the refrigerator in time, and take it out when drinking. This can avoid the high temperature, which will cause the yogurt to have too high acidity and stimulate the stomach. Also, try to drink as close as possible to the date of manufacture.

Subsequently, the reporter contacted a senior engineer in the fermentation room of the Institute of Food and Industry of Taiyuan City. The other party said that excessive fermentation would increase the acidity of the yogurt, while the activity of the lactic acid bacteria decreased, and some changes in taste, but for health. It will not do harm to our health. However, people with bad stomachs should not drink yogurt for a long time.
