Cold salad oil is a refined food oil made by refining crude oil, which can be used for raw food. It is named salad oil because it is especially suitable for western salad salad. Salad oil is light yellow, clear, transparent, odorless and good in taste, and it does not foam and smoke when used in cooking. It can remain clear and transparent (except peanut salad oil) after being refrigerated for 5.5 hours at 0℃. It is mainly used for cold meal and salad oil besides cooking and frying, and can also be used as raw oil for margarine, shortening, mayonnaise and various seasoning oils.
Eating salad oil cold will directly affect the flavor, taste and appearance of dishes and foods, so the requirements for its freshness, flavor and color are strict. Considering the storage and transportation factors, cold oil also requires high thermal stability and flavor stability.
