很多时候我们买多了豆腐脑或者自己做多了豆腐脑就会想着，要不先放着等等在吃吧，但是往往放着放着就忘记了，就会发现豆腐脑变酸了，那么豆腐脑放着出现酸味了还能吃吗？

　　Most of the time we buy more bean curd or do more bean curd will think, or put it and so on to eat it, but often put it and forget, you will find that bean curd has become sour, so bean curd put sour taste can you eat it?

　　一般豆腐脑酸有可能是豆腐脑本身加入了盐水，或者在制作过程中加入了发酵工艺，从而有一些发酸的口感或气味。若是成分里有盐水，或者豆腐脑新鲜未拆封，还在保质期内，一般还是可以食用的。但若酸味明显，而且有变黏等表现，一般是由于购买后保质期已过，或者放置时间过长等导致的豆腐脑变质，此时不建议再食用。

　　Generally, it is possible that the bean curd itself has been added with salt water, or the fermentation process has been added in the production process, so that it has some sour taste or smell. If there is salt water in the ingredients, or fresh bean curd, still in the shelf life, it is generally edible. But if the sour taste is obvious, and there is a sticky performance, generally due to the shelf life after purchase has passed, or placed for too long time caused by the deterioration of tofu brain, it is not recommended to eat again at this time.

　　豆腐脑富含丰富的蛋白质，所以本身保质期并不长，过期或长时间放置后，其中所富含的蛋白质容易发生腐败、变质，同时也容易被外界的腐败杂菌侵袭。虽然有些豆腐脑肉眼观察其外观可能没有明显的变化，但是仍然不能排除变质的情况。

　　Tofu brain is rich in protein, so its shelf life is not long, expired or placed for a long time, which is rich in protein is prone to corruption, deterioration, but also easy to be the outside corrupt miscellaneous bacteria attack. Although some bean curd naked eye observation of its appearance may not be obvious changes, but still can not rule out deterioration.

　　食用变酸的豆腐脑后，轻者可能会出现腹泻、胃痛等症状，严重者可出现食物中毒，主要表现为恶心、呕吐、食欲下降、严重腹泻，甚全身发冷等不适症状。而且也有一部分人认为加热发酸的豆腐脑即可去除豆腐脑里的霉菌、细菌等有害物质，但实际上是一种误解，高温下也很难将这些有害物质去除。

　　After eating sour tofu, mild cases may appear diarrhea, stomach pain and other symptoms, and serious cases may appear food poisoning, mainly manifested as nausea, vomiting, loss of appetite, severe diarrhea, and even the whole body chills and other uncomfortable symptoms. In addition, some people believe that heating sour tofu can remove harmful substances such as mold and bacteria, but this is a misunderstanding, and it is difficult to remove these harmful substances even at high temperature.

　　建议立即停止食用，若已经出现明显不适症状，而且无法缓解，应及时到医院进行相应检查，以免耽误时间。此外，建议豆腐脑现吃现买，或者将豆腐脑用盐水煮开，放凉后同水一起进行保鲜。对于鲜豆腐脑也可进行冷冻保存，冷藏后的豆腐脑颜色泛黄、口感更佳，但在烹饪前应进行自然解冻，以便更容易与其他材料进行搭配。

　　It is recommended to stop eating immediately. If obvious uncomfortable symptoms have appeared and cannot be relieved, you should go to the hospital for corresponding examination in time to avoid delaying the treatment time. In addition, it is recommended to buy tofu curd on the spot, or boil it in salt water and cool it with water for freshness. Fresh tofu curd can also be frozen and preserved. It turns yellow and tastes better after refrigeration, but it should be thawed naturally before cooking to make it easier to mix with other ingredients.

　　平常一定要注意购买一些新鲜的豆腐脑，同时还要注意把豆腐放在冰箱当中，可能温度比较低，有利于存放的时间延长，而且不容易出现变质的现象，多吃新鲜的食材，避免出现肠道疾病或者是肠道功能紊乱。

　　Usually, we must pay attention to buy some fresh tofu, but also pay attention to the tofu in the refrigerator, the temperature may be relatively low, is conducive to prolong the storage time, and is not prone to deterioration, eat more fresh ingredients, to avoid intestinal disease or intestinal dysfunction.
