Green Potatoes
Green potatoes are not a new type of potato. Any
potato can turn green and is not exactly a good thing.
Potatoes are one of the most popular vegetables in the world. Only a
few crops are cultivated more than potatoes.
Since potatoes are an essential part of people’s
diet in many countries; assuring a good quality product is very
important. A potato that has a green color is not exactly what you
would like to encounter in your crops. The green color does not mean
that the potato is too new and needs more time to be fully grown.
Green potatoes do not refer to the small green
spot that sometimes potatoes have. This green pigmentation is a signal
that the potato might poison you if you eat it. The green color is just
under the skin and covers the whole potato. Like in many vegetables
there are certain areas of the potato tuber that you should not eat.
The sprouts or eyes in the potatoes should not be eaten under any
conditions. There are toxins that accumulate precisely in those areas
of the potato. That green under the skin is a result of chlorophyll.
Chlorophyll is the substance that makes all plants
green but that chemical is not the one that is dangerous. A potato with
the green color means it has been exposed to sunlight for too lo ng.
When the chlorophyll is synthesized in the potato plant there are other
reactions that are the ones that cause problems. These reactions create
a toxin called solanine. This compound can be very harmful for the
human body if it is ingested in big amounts. The presence of high
amounts of chlorophyll under the skin of the potato generally indicates
high concentrations of solanine in the potato.
Solanine can cause nausea, vomiting, confusion,
convulsions and in the most extreme cases death. People that are in
higher risk of poisoning are children, people over the age of 60,
pregnant women and people suffering from illnesses. There are many
alternatives to prevent problems with green potatoes. Before cooking
any potato; cut all sprouts then check for any green coloring under the
skin as you peel them.
When cut in a half if the potato's border is completely green is better to
discard it. A potato with only a couple of green spots can be either
cooked after cutting the green areas or you can get rid of it if you
feel is too risky. Once is cooked if you feel a bitter taste just throw it away.
