Can. Onion storage time is too long, there will be sprouting, long buds, nutrients will be transferred to the sprouting part, will only make the nutritional value of the onion is reduced, will not produce toxic substances, therefore, sprouting onions can continue to eat, just taste worse. How to avoid onion germination: the onion surface moisture wipe clean, and then dry for a while, put in a dry ventilated place to save can avoid onion germination.

Can eat. Generally speaking, onions stored for a long time, sprouting long buds, the nutrients will be transferred to the sprouting part, just will make the nutritional value of the onion reduced, will not produce toxic substances, therefore, the sprouting of the onion can still continue to eat, just taste worse.

How to avoid onion germination:

1, the onion surface moisture wipe clean, and then dry for a short while, put in a dry ventilated place to save, so that to a certain extent to avoid onion germination.

2, eat as soon as possible. The reason why the onion will sprout, a large part of the reason is that the storage time is too long, the onion respiration to strengthen, so that the onion itself changes, the phenomenon of germination and sprouting, therefore, the onion should not be stored for a long time, it is recommended to consume as soon as possible, should not be more than half a month.

3, should not be put in water. Put the onion in the water, is to provide the environment for the growth of onions, promote the germination of onions, therefore, it is generally not recommended to put the onion in the water or a more humid place.

4, should not be sealed in plastic bags. Onions will carry out certain respiratory effects, sealed in plastic bags, easy to make water vapor aggregation, increase humidity, and then increase the chance of onion germination, therefore, generally to take out the onions, do not put into a closed environment.
