It was not created, it is the unripe fruit of the chile plant and is natural.
In unripe fruit, the plant has made the fruit acids but not yet made the sugars to make the fruit sweet.
Tomatoes are a green fruit. Fried green tomatoes are a food dish found in the Southern U.S., made from unripe tomatoes.
I presume that the bitter peppers you are referring to are green. Bell peppers change from green to yellow, through orange into red as they ripen. The red ones are far sweeter than the green ones and green ones, by definition, are unripe. As you know, they can be eaten when green and unripe but when they are too unripe, they are bitter and taste unpleasant. The best way of ripening them is to leave them on the plant to ripen in the sun. This is fine if you grow them yourself. If you buy them, either pick yellow or red peppers if the recipe allows you to, or you can ripen the green ones a little once you have bought them by storing them a while longer before using them. They will not ripen enough to change color but they will be a little less bitter. Hope this helps.
