A press cake or oil cake is the solid matter remaining after pressing something to extract the liquids. Their most common use is in animal feed.

Contents

Some foods whose processing creates press cakes are olives for olive oil ( pomace ), peanuts for peanut oil, coconut flesh for coconut cream and milk ( sapal ), grapes for wine ( pomace ), apples for cider (pomace), mustard cake, and soybeans for soy milk (used to make tofu) (this is called soy pulp) or oil. Other common press cakes come from flax seed (linseed), cottonseed, and sunflower seeds. However, some specific kinds may be toxic, and are rather used as fertilizer; for example, cottonseed contains a toxic pigment, gossypol, that must be removed before processing. [1]

Culinary use

In Nepalese cuisine the oil cake of the Persian walnut is used for culinary purposes, and it is also applied to the forehead to treat headaches. [2] In some regions it is used as boiler fuel as a means of reducing energy costs, for which it is quite suitable. [3]

Military use

In 1942 the Porton Down biology department outsourced the production of 5,273,400 linseed press cakes to Olympia Oil and Cake Company in Blackburn Meadows [4] which would then be infected with Bacillus anthracis (bacteria that causes Anthrax) and using in the biological warfare program Operation Vegetarian.

Flax, also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae.

Textiles made from flax are known in English as linen and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil. In addition to referring to the plant, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant and appears to have been domesticated just once from the wild species Linum bienne, called pale flax. The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium.

<span class="mw-page-title-main">Oil paint</span> Type of slow-drying paint

Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. The viscosity of the paint may be modified by the addition of a solvent such as turpentine or white spirit, and varnish may be added to increase the glossiness of the dried oil paint film. The addition of oil or alkyd medium can also be used to modify the viscosity and drying time of oil paint. Oil paints were first used in Asia as early as the 7th century AD and can be seen in examples of Buddhist paintings in Afghanistan. Oil-based paints made their way to Europe by the 12th century and were used for simple decoration, but oil painting did not begin to be adopted as an artistic medium there until the early 15th century. Common modern applications of oil paint are in finishing and protection of wood in buildings and exposed metal structures such as ships and bridges. Its hard-wearing properties and luminous colors make it desirable for both interior and exterior use on wood and metal. Due to its slow-drying properties, it has recently been used in paint-on-glass animation. The thickness of the coat has considerable bearing on the time required for drying: thin coats of oil paint dry relatively quickly.
