Three problems of bread preservation

4hw.com.cn: Nowadays, people's life rhythm is faster and faster. Many office workers are too late to have breakfast. Some people will make many kinds of bread in their spare time on weekends, in case of an emergency or when they come to work directly for breakfast, but there are too many bread to make and they can't eat it all at once. How can we keep it fresh?

Three problems about keeping bread fresh

Q: why does sweet bread sometimes harden in less than a day even when it is kept at room temperature? Isn't it with a shelf life of 2-3 days?

A: the way of making bread is very important. High quality bread can be preserved for a long time. The dough should be fully kneaded, the moisture content of bread should not be too low, and the fermentation and baking should be correct, so as to make bread that will not have too much change in taste in 2-3 days.

Q: why do many toast and sweet bread bought in the supermarket have a shelf life of 5-7 days?

A: commercial bread generally contains preservatives (such as calcium propionate), which can prevent bread from mildew, and also contains bread improver, which can improve bread tissue structure and delay bread aging. Therefore, the shelf life of bread can be extended by 3-4 days. The hand-made bread made in the bakery does not contain such additives, so the shelf life will be greatly shortened.

Why is bread sticky after two days?

A: sticky inside is also a feature of bread deterioration. To reduce the chance of this, the bread must be thoroughly baked. Especially for toast, the temperature in the center of bread can reach 80 ℃ in the last few minutes of baking. If the baking time is not enough, the interior of toast can not be fully cooked and easily rotten.

Tips for keeping bread fresh

Bread without preservatives will gradually harden and deteriorate from the moment when it comes out of the oven, so once the bread taken out of the oven is cooled at room temperature, it should be immediately put into the freezer of the refrigerator to keep it fresh longer. {www.zhichangsHi.com}

Bread can't be put in the freezer, because it will only let the bread lose water and dry. In addition, if the amount is large, you can also buy an independent freezer to avoid putting together with raw food such as meat, or you can use sealed boxes for storage, which is more hygienic and safe.

So, how to deal with frozen bread when you want to eat it?

Take the bread out of the freezer and thaw it at room temperature for about half an hour. In addition, you can take it to steam or bake, and you can eat soft bread. Unlike other foods, if you can't eat all the bread from the freezer, you can put it back in the freezer to keep it fresh.

In this way, bread can be kept fresh for a long time and soft bread can be eaten every day.

Other ways to keep bread fresh

1. Steam slightly: put the bread in the steaming sieve and steam slightly, which can also make the bread fresh again. Note that a small amount of vinegar is put in the water of steamed bread, and the effect will be very good.

2. Put some raw potatoes or a pinch of salt on the bottom of the scrubbed and dried glass or enamel ware, and then put the bread in, so that the bread will not harden. To prevent the smell, put some fresh apples in.

3. Celery: take a celery and wash it and put it into the bread bag. This will keep the bread fresh and taste good.

4. Wet paper: keep the bread fresh when traveling. You can find several pieces of paper to soak in cold water, wrap them outside the original wrapping paper of the bread, and then put them in a plastic bag to fasten the mouth of the bag.

5. Fresh keeping paper: wrap the bread with three layers of fresh keeping paper and store it in the refrigerator. It can keep fresh without losing water.

Tips on baking: when we bake or heat bread or other food materials, we can avoid using tin paper, so as not to cause chemical effects. We can choose some banana leaves or oil paper used in baking, which can not only reduce the trouble of cleaning, but also keep clean and sanitary!
