It is an exception to the regulations governing the use of the property. For example, a use variance might allow a dentist to place his office in a residential neighborhood.

Most of the trans fat in the foods we eat is formed through a manufacturing process that adds hydrogen to vegetable oil, which converts the liquid into a solid fat at room temperature. This process is called hydrogenation.
Small amounts of trans fat (generally 2-5% of the fat content) are naturally present in foods such as dairy products, beef and lamb. Some liquid vegetable oils such as canola and soybean, and fish oils, can also contain small amounts of trans fats, which can be formed during the commercial refinement of these oils.These oils may contain up to 2.5% trans fatty acids, but are also important sources of the essential omega-3 and omega-6 fatty acids.Trans fats can also be formed when manufacturers use a chemical process that turns liquid oil into a semi-solid form, like shortening and margarines.The process is referred to as partial hydrogenation.. Fats and oils that are solid or semi-solid at room temperature have advantages for food production.hese oils may contain up to 2.5% trans fatty acids, but are also important sources of the essential omega-3 and omega-6 fatty acids. Trans fats can also be formed when manufacturers use a chemical process that turns liquid oil into a semi-solid form, like shortening and margarines.
