'''Degreasing''' is the process of removing [[grease]] or [[oil]] from a surface, typically in the context of [[cleaning]] or [[cooking]]. This process is essential in various industries, including [[food preparation]], [[manufacturing]], and [[automotive maintenance]].

	~~Various methods can be used to trim the fat content of a meal during preparation. Common methods include substituting food items, removing naturally occurring fat, and conservatively adding fat.~~

	~~Fat substitution is a technique where one ingredient is replaced with another~~, ~~usually healthier, ingredient.

Degreasing can be achieved through several methods, depending on the context and the materials involved. Common methods include:

	Food items can also be substituted to reduce fat content. For instance, egg whites, which are lower in fat than whole eggs, can be used in place of whole eggs. Alternatively, low-fat products like skimmed milk can be used as ingredients in cooking.		=== Solvent Degreasing ===

	~~===Degreasing Liquids===~~		Solvent degreasing involves the use of chemical [[solvents]] to dissolve and remove grease. This method is often used in industrial settings where mechanical parts need to be cleaned. Solvents such as [[trichloroethylene]] and [[acetone]] are commonly used.

The fat can be skimmed off the liquid with a small ladle, spoon, or cup as the liquid simmers and then discarded~~.

	As an alternative to a ladle, a degreasing cup can be used to skim the fat off hot liquids. This is a clear plastic or glass cup that resembles a teapot, with a spout that comes out of the bottom. The liquid and juices are poured into the cup and then poured out, leaving the fat behind.		=== Aqueous Degreasing ===

Aqueous degreasing uses water-based solutions, often containing [[detergents]] or [[surfactants]], to emulsify and remove grease. This method is more environmentally friendly compared to solvent degreasing and is widely used in [[kitchen]] and [[household cleaning]].

	===Degreasing ~~Solid Food Items~~===		=== Mechanical Degreasing ===
	Some items, such as roasted foods and other cooked food items like pizza, can sometimes be oily and greasy. Degreasing them after preparation may provide a solution to this problem. Fried foods, such as French fries, can often be degreased without affecting their crispiness by blotting out the oil with tissue paper.

	~~==Commercial Degreasing==~~		Mechanical degreasing involves the use of physical actions, such as [[scrubbing]] or [[abrasion]], to remove grease from surfaces. This method is often used in combination with solvents or aqueous solutions to enhance effectiveness.

The process involves skimming off the fat that rises to the surface during cooking. This not only improves the [[flavor]] and [[texture]] of the dish but also makes it healthier by reducing the [[fat content]].

			== Industrial Applications ==

			In industrial settings, degreasing is crucial for maintaining the efficiency and longevity of [[machinery]]. Grease can accumulate on [[machine parts]], leading to increased wear and tear, overheating, and potential [[malfunction]]. Regular degreasing helps prevent these issues and ensures smooth operation.

			== Environmental Considerations ==

			The choice of degreasing method can have significant environmental impacts. Solvent degreasing, while effective, can release [[volatile organic compounds]] (VOCs) into the atmosphere, contributing to [[air pollution]]. Aqueous degreasing is generally more sustainable, but it requires proper disposal of the used solutions to prevent [[water pollution]].

'''Degreasing''', also known as '''defatting''' or '''fat trimming''', involves removing fatty acids from an object. In culinary science, the goal of degreasing is to reduce the fat content of a meal.

==Degreasing Food==
Degreasing is often employed by [[dieters]], especially those following low-fat diets, to reduce their fat consumption for [[weight loss]] purposes. Since 1g of fat contains 9 calories, compared to the 4 calories found in carbohydrates and proteins, reducing fat consumption is seen as an efficient way to lose weight without significantly sacrificing the total volume of food. Degreasing can be done during meal preparation to reduce the energy content of the food or applied to prepared food in social situations, such as when consuming high-fat restaurant meals.

Individuals aiming to reduce their cholesterol levels or overall fat intake, particularly those with [[hypercholesterolemia]], often use degreasing techniques to minimize fat consumption.

=== Degreasing a Meal During Preparation ===
