Under no circumstances should tomatoes be left on branches. You need to pick them all at once, even if there are green fruits left. However, it is in green tomatoes that many dangerous substances can be found during the study. We are talking about solanine, a toxic substance that can cause severe harm to human health. Just 5-6 fruits will be enough for a person to get serious food poisoning.
Green tomatoes also contain tomatin. Although this substance is less harmful than solanine, it can also cause food poisoning if you eat a lot of unripe fruit.
But not all unripe tomatoes should be thrown away. If a tomato looks like a ripe tomato in shape and size, but differs only in color, it can be canned and you don't have to worry about possible poisoning. Green tomatoes that have just started to turn red are also safe.
