Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock.
Waste vegetable oil that has been filtered. Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO).
If the temperature does not exceed 120 °F, the oil can be called "cold-pressed". [3] In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as hexane. Chemical extraction is cheaper and more efficient than mechanical extraction, at a large scale, leaving only 0.5–0.7% of the oil in the plant solids ...
The LRP had a cold-weather warfare equivalent, the Ration, Cold Weather (RCW). The LRP and RCW were mostly superseded by the Meal, Ready-to-Eat (MRE) in the 1980s. They are no longer produced or used by the U.S. military, having been replaced in 2001 by the Meal, Cold Weather/Food Packet, Long Range Patrol ( MCW/LRP ), which combines the ...
A mix of oils other than the aforementioned exceptions may simply be listed as "vegetable oil" in Canada; however, if the food product is a cooking oil, salad oil or table oil, the type of oil must be specified and listing "vegetable oil" as an ingredient is not acceptable.

Flash freezing being used for cryopreservation. Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below [clarification needed] the freezing point of water. Thus, smaller ice crystals are formed, causing less damage to cell membranes. [3]
How well it works depends on the heating system, the engine, the type of vegetable oil (thinner is easier), and the climate (warmer is easier). Some data is available on results users are seeing. [6] As vegetable oil has become more popular as a fuel, engines are being designed to handle it better.
