The answer is edible, because ginger is not like potatoes. After potato germinates, a substance called solanine will be produced in the bud eye, which is a nerve agent and has certain adverse effects on human body. But after ginger germinates, we will find that the pulp inside will become empty, but the nutritional value will decrease and the carbohydrate content will also decrease. Nutrition will supply the growth of buds, but it is still edible. 2. How to preserve it can prevent ginger from sprouting. The ginger we buy will germinate if it is not well preserved, because the water content of ginger itself is relatively high. If it is placed in an environment with suitable temperature and humidity, it will not germinate after a period of time. What can be done to prevent germination? We can wrap ginger with plastic wrap or tin foil, then wrap it in plastic bags to ensure that it is completely wrapped and stored in the refrigerator. In this way, Jiang can isolate the humid air and the oxygen he needs. In addition, this can also ensure that the water of ginger itself does not lose, so it can be preserved for a long time. Wrap the ginger in plastic wrap or tin foil, then wrap it in plastic bag and put it in the refrigerator. This is because it is wrapped with plastic wrap or tin foil, which isolates humid air and oxygen, and at the same time keeps the moisture of ginger from evaporating, so it can be preserved for a long time. Eating ginger also has many benefits. The most widely known is that it can warm the stomach. In addition, it can also give gastrointestinal congestion and enhance digestion, effectively relieve abdominal pain, bloating and other symptoms. And eating ginger can dilate blood vessels, so people will feel hot after eating ginger.
