Nut fat is obtained from selected nuts through the process of pressing nut pulp. It has a light yellow or greenish color. It is characterized by a delicate nutty and sweet flavor with a hint of caramel and a mild nutty aroma. It is also important to note that nut fat is one of the richest sources of unsaturated fatty acids, including omega-3 (linolenic acid), omega-6 (linoleic acid) and omega-9 (fatty acids).

3. Application of oil in the kitchen

Due to its mild flavor, Italian nut oil is recommended mainly as an ingredient in salads, raw food, dressings or sauces. It also works well as an additive to: pancakes, cakes, pastries and desserts served cold. It should be noted that it should not be used for frying due to its susceptibility to oxidation. This oil should only be used in the cold as it loses its valuable health properties after heating and its taste becomes bitter.

4. Oil storage

This type of oil is obtained through cold pressing, so it is important to pay attention to its proper storage and quick use. When we buy cold pressed oils, we should make sure that they are stored in a dark glass bottle. The best place to store the oil is in a cool and dark place. If the oil is stored properly, it should remain fresh for a period of three months, keep in mind that the expiration date of nut oil is very short.
