Oils, onion Use and Manufacturing

Methods of Manufacturing

It is obtained from the bulbs of onion (Allium cepa), a herbaceous plant of the Liliaceae family, which is ground and steam distilled. The yield is about 0.01%～0.015% (fresh raw materials) or 0.05% (dry materials). Produced all over the world. Because the quantity is small and expensive, it is often dissolved in a solvent when used, emulsified by adding an emulsifier such as gum arabic, and then spray-dried to powder before use.

Uses

my country~"s GB 2760-96 stipulates that it is temporarily allowed to use edible spices. Mainly used for sausages, soups, sauces, etc.
