The history of the airplane shows it was invented by Orville (1871-1948) and Wilbur (1867-1912) Wright. They got the patent 9 months prior to their flight in December 1903. The Early History of Flight. There are pictures showing Orville Wright on the plane flying.
Naturally occurring pectin is a soluble fiber found in many fruits and plants. Pectin is a great example of a natural polymer, and is composed of pectic acid and pectinic acid molecules. It is basically a compound with a bunch of sugars and acids attached to it. (I always find the chemical structure fun!) Every plant contains some amount, sometimes just a very small amount, of pectin.
Pectin is a naturally occurring carbohydrate in fruit that is concentrated in the fruit's skin and the core. When cooked, Pectin solidifies to a gel, causing fruit preserves to set.ruits that are high in Pectin include Apples, Blackberries, Cape Gooseberries, Crab Apples, Cranberries, Gooseberries, Grapes, Medlars, Plums and Quince. Any citrus fruit peel is also very high in Pectin. Sometimes you will see recipes combining ripe and unripe fruit together. That is done for a reason.
