Edible oils have varying densities, so measuring by weight in kilograms provides a more accurate representation of the quantity. Additionally, weight measurements are more consistent across different types of oils compared to volume measurements in liters, which can be affected by factors such as temperature and viscosity.
Edible oils are less dense than water due to their molecular structure, which causes them to float. This difference in density is primarily because oils are composed of nonpolar molecules, whereas water is a polar molecule. The polarity of water allows molecules to be packed more closely, thus making it denser than oils.
Single cell oils (SCO) are the edible oils extracted from micro-organisms-the single-celled entities that are at the bottom of the food chain.The best producers with the highest oil contents are various species of yeasts and fungi with several key algae that are also able to produce high levels of nutritionally important PUFA. Their potential to produce PUFA has now galvanized the current interest in these SCO as oils rich in highly desirable fatty acids essential for our well being and not readily available either from plants or animals
The specific heat of fat varies depending on the type of fat. However, the specific heat capacity of most edible fats and oils is typically around 2.0 J/g°C.
When edible oil is exposed to air, it is attacked by atmospheric oxygen which yields free fatty acids in the oil and this leads to a process called rancidity. Peroxide value measures the amount of rancidity that has taken place. Ejike(swaggalicious)
Many edible seeds are used in oil production.The most commonly eaten seeds used also for oil are sunflower, sesame, and pumpkin. Corn (maize) is also technically a seed, and is used for oil. Some other seed oils are grape seed, safflower, and rapeseed (canola).
You are essentially answering your own answer within your own question. Vegetable oils and other food oils are edible oils. The other oils that cannot be eaten can be grouped into this other major category called non edible oils such as engine oils, etc.
Essential oils derived from edible foods are also edible. They may be too strong in flavor or irritating to your mouth (such as oils from hot peppers).

It depends on the oil and it's use. all oils can be measured in fluid ounces, gallons, quarts or liters Fuel oil is measured in barrels (42 gallons), or bunkers 5100 barrels lubricating oils can be measured in drums (55 gallons) and some heavy lubricating oils and greases are measured by weight
Animal fats tend to go rancid with time. Vegetable oils will too eventually, but have a longer shelf life.
4.5 million tons produced everyday.................
Polymerization - oxidation, oils which are designed to, e.g. linseed oil or having double bonds like many edible oils
This category covers establishments primarily involved in manufacturing shortening, table oils, margarine, and other edible fats and oils that are not elsewhere classified
The fruit is edible when ripe. Palatable but not particularly tasty. Theoretically similar to avocado when perfect. The Nuts are edible when roasted and the native Californians made a paste which has been likened to chocolate with the stimulating effect and much of the flavor of coffee. The volatile oils in the fruit make it unpalatable when unripe. These same oils are present in the nut which must be roasted to make the nut edible.
