The restaurant can sell food that is about to expire, and yogurt has a 1 week expiration date of 6

1. Try not to drink expired yogurt, the yogurt within the shelf life contains live bacteria, which is beneficial to the body, of course, the yogurt needs to be refrigerated, and the live bacteria in the yogurt at room temperature for a long time will also die, so the live bacteria in the expired yogurt will naturally die, which loses the meaning of drinking yogurt, but the protein and calcium in the expired yogurt still exist.

2. If the yogurt is only expired for 1-2 days, you can still try to drink it, but if it expires for many days, it is best not to drink it.

3. When buying yogurt, you must buy recently produced, if the discounted product is relatively short from the shelf life, you can buy a small amount and drink it as soon as possible, the general business will leave room for the shelf life, not that a certain product can really not be used or eaten anymore when it reaches the shelf life, but for the sake of safety, you should avoid using expired products.

4. If the taste does not change, it can continue to drink, but if it has the taste of alcohol or sake lees, or if it has mold, rotten smell and other abnormal circumstances, the expired yogurt cannot continue to drink.

Hehe! The taste of yogurt is naturally "sour".

Maybe you mean that the flavor of the product has changed, such as becoming more acidic.

Yogurt (not those "sour yogurt" and "yogurt" "blended sour drinks") need to be stored at low temperature as required, and you buy it in the supermarket in a low-temperature storage cabinet, so you should also store it in the refrigerator at low temperature after buying it home.

Since yogurt contains live lactic acid bacteria, these live bacteria may still be "post-fermented", especially at room temperature. The result of this over-fermentation is that the flavor is very different from that before leaving the factory, and the most common intuitive feeling is "too acidic".

So, try to buy products that are close to the production date. The flavor and nutrition are the best. In a slightly larger market, it is easier to buy products within the same day or a day or two, because they give them one by one to give them to the supermarket.

It doesn't matter if you see the date of the loss of the shirt on the outside of the shelf, flip it inside, and basically the rental god will find the fresh date. Because their promoters will often "tally", putting the date far away from the outside and "hiding" it from the inside.
