Guidelines for Storing and Using Cooking Oils
If properly stored, olive oil can be consumed even after the expiration date without health risks. Light fruity olive oil lasts about a year, medium one lasts two years, and intense olive oil can last up to three years. Seed oils generally have a shelf life of 12-18 months but can reach 18-20 months if well maintained.
Signs of Spoilage
Over time, oil loses its qualities. It is advisable to consume olive oil within 12-18 months. Exposure to air oxidizes the oil, altering its taste. It is best to store it at a temperature between 12° and 18° C, away from light and heat.
Shelf Life of Sunflower Oil After Opening
Sunflower seed oil, like other seed oils, typically lasts 12-18 months. After that, it tends to become rancid. Cold mechanical extraction better preserves its nutritional properties.
Assessing Oil Quality
To determine if an oil is good, use your sense of smell. If you detect scents of olives, grass, fruit, and vegetables when sniffing, the oil is likely good.
Identifying Rancid Oil
Check the expiration date and appearance. Fresh oil has an intense green color and a fruity aroma, while old oil turns yellowish, cloudy, and bitter in taste.
Disposing of Expired Seed Oil
Dispose of expired seed oil at municipal recycling centers or at designated collection points in some supermarkets or gas stations.
Proper Storage of Seed Oil
Keep seed oil in a dark place, away from heat sources, and tightly sealed to prevent oxidation.
