Will shortening deteriorate if it is kept for a long time?

Shortened oil will deteriorate if it is kept for a long time, so it must be carefully preserved.

The storage temperature of ghee is 15-25℃, and it can be stored in a dark, dry, ventilated, cool and clean place for at least 12 months.

Look at the oil If it is milky white, it means there is water in it, and the whiter it means more water. Oil with high water content will be turbid and easy to deteriorate. When heated, there will be a lot of foam and water explosion, and the lampblack will be bitter.

Generally speaking, shortening refers to refined animal and vegetable oil, hydrogenated oil or the mixture of the above oils with or without quenching, and is a solid or liquid oil with plasticity, emulsification and other functional characteristics.
