As a common staple food, steamed bread is also a frequent guest on the dining table of every household, if you feel that you throw it away, it is a pity that every time you buy steamed bread, please think carefully before buying steamed bread, buy as much as you eat, and don't let waste become an excuse for affecting health

Steamed bread expired, don't eat it, you don't see mold, in fact, moldy some bacterial infections are invisible to our naked eyes, eat bad stomach, it's troublesome, eat moldy food for a long time, it is very harmful to health, we all know moldy food carcinogens.

Of course, you can't eat steamed buns when they expire. Moreover, the shelf life of steamed bread is very short, and if it is not stored properly, it cannot be eaten after one night. Eating expired food is harmful to the body.

Edible alkali expires to steam steamed buns. Steamed buns steamed with expired alkaline noodles can be eaten. Because alkali itself is a stable substance and does not react with substances in the air, it is not easy to deteriorate.

However, due to the effect of water absorption, it may produce water content, so it should be considered in terms of dosage. Alkali storage method: sealed, sealed in water.

It can be stored in the refrigerator.

Edible alkali can not be steamed after expiration, because edible alkali is an alkaline substance, and the chemical name is called sodium bicarbonate, so it belongs to a chemical, and chemical substances will produce toxic substances after expiration, so it is best not to use them. It is better to wash vegetables or remove oil stains with expired edible alkali, so that it can be enough to do not waste, and the alkalinity of edible alkali is relatively strong, so if you use it too much or wash it for a long time, it may cause harm to **.

Related Notes:

If the steamed bread is cooled, it cannot be put in the refrigerator with hot air, and the steamed bread will produce steam, which is easy to form frost in the refrigerator.

Put the cooled steamed buns in a clean plastic bag for food, and if there is no new bag for food, you can keep the plastic bag for shopping in the supermarket for use.

Put the plastic bag with the steamed bread into the refrigerator freezer, and the plastic bag should be tied tightly so that it cannot leak air to prevent the steamed bread from losing moisture.

Put the steamed bread that you can't finish eating next to it to cool, and after it cools, wrap the steamed bread one by one with plastic wrap and seal it, so that the steamed bread is isolated from the outside air, and the plastic wrap should be wrapped in a few more layers. After wrapping, put the steamed bread in the fresh-keeping bag, the fresh-keeping bag is also the amount of a meal, after loading, the air in the fresh-keeping bag is discharged, and then the mouth is tightly sealed, and then it can be put into the freezer area of the refrigerator for preservation, which can not only isolate the outside air, avoid the breeding of bacteria, but also prolong the preservation time of the steamed bread.

Because the water content of steamed bread is low and it is easy to evaporate the water, it is not easy to deteriorate, although this is the case, it is impossible to store the steamed bread without fermentation for a long time, because the steamed bread has poor air permeability and is easy to deteriorate.

Introduction:

Yeast (saccharomyces) is a commonly used eukaryotic receptor cell in gene cloning experiments, and yeast culture is as convenient as culture of E. coli. There are also many types of yeast cloning vectors. Yeast also has plasmids, and this 2 m long plasmid is called a 2 m plasmid, which is about 6300 bp.

This plasmid exists outside the chromosomes in the nucleus for at least some time, and the plasmid in the 2 m plasmid and E. coli can be used to construct a shuttle plasmid that can shuttle between bacterial and yeast cells. Yeast cloning vectors are built on this basis.

Yeast is a single-celled fungus and is not a unit of phylogenetic classification. A tiny single-celled microorganism invisible to the naked eye, which can ferment sugar into alcohol and carbon dioxide, distributed throughout nature, is a typical heterotrophic facultative anaerobic microorganism, can survive under aerobic and anaerobic conditions, and is a natural starter culture.

Generally refers to a variety of single-celled fungi that can ferment sugars, which can be used in brewing and production, and can also be pathogenic bacteria - model organisms for genetic engineering and cell cycle research. Yeast is the earliest microbial in the history of human civilization.

There are more than 1,000 species of yeast, which are known to be divided into three groups based on their ability to produce spores (ascospores and basidiospores): the spores-forming strains belong to ascomycetes and basidiomycetes. Fungi that do not form spores but reproduce mainly through budding are called incomplete fungi, or "pseudoyeasts" (yeast-like).

A very small percentage of yeasts are known to be classified into Ascomycetes. Yeast is widely distributed in nature and grows mainly in acidic, moist, sugary environments. In February 2018, the precise custom synthesis of yeast long chromosomes won the 2017 Top Ten Advances in Chinese Science by the Ministry of Science and Technology.
