Parchment paper

Parchment paper, also known as baking paper, is a cellulose-based paper whose material has been processed so as to obtain additional properties such as non-stickiness, grease resistance, resistance to humidity and heat resistance.^[1][2] It is commonly used in baking and cooking as a disposable non-stick paper. It is greaseproof paper that can be used for several different applications, its surface prevents the food from sticking, and also is highly heat-resistant and can be used in temperatures up to 220°C.^[3][4] It should not be confused with waxed paper, which is paper that has been coated with wax.

To get its non-stick properties, baking paper is coated either with a substance called "quilon" or with silicone; the former is considered less safe.^[5][6]

A common use is to eliminate the need to grease sheet pans, allowing very rapid turn-around of batches of baked goods with minimal clean-up. Parchment paper is also used to cook en papillote, a technique where food is steamed or cooked within closed pouches made from parchment paper.

Parchment paper can be used in most applications that call for wax paper as a non-stick surface. The reverse is not true, as using wax paper would cause smoke in the oven and would adversely affect flavor.^[7]

The non-stick properties can be also achieved by employing a coated paper, for which a suitable release agent—a coating with a low surface energy and capability to withstand the temperatures involved in the baking or roasting process—is deposited onto the paper's surface; silicone (cured with a suitable catalyst) is frequently used.

Parchment paper also has relevant properties for other industries. In the textile tube industry, an outer layer of parchment confers the necessary resistance to abrasion, heat and oil. In other industries, parchment is used as a processing aid due to its release properties, whether for furniture laminate manufacturing and rubber vulcanization.

In creative forms such as origami thin uncoated parchment paper is often used for tessellations and complex models.

Parchment paper is composed of cellulosic fibers and therefore is considered compostable both in an industrial setting (EN13432) and at home.
