According to surveys among tourists, more than half of them bought olive oil during their holidays in Crete. It is an excellent and healthy choice, but you have to remember that this popular "souvenir" is quite fragile. After arriving home, it is not worth leaving it only for special occasions.
Oil is one of those products that must be properly stored and consumed within 2 years of the olive harvest. Some producers give this date on the packaging, so at the time of purchase we can check how fresh the oil is being bought. This is important because the properties and taste qualities of the oil are slowly degraded practically from the moment of obtaining the finished product. So you need to know how to store oil to slow down the aging process. The answer to this question will be helped by scientific research in which the impact of various types of packaging on the chemical composition, changes in the acidity and flavor of the oil was checked.
