Olives are soaked in lye (dilute NaOH, 2–4%) for 8–10 hours to hydrolyse the oleuropein. They are usually considered "treated" when the lye has penetrated two-thirds of the way into the fruit. They are then washed once or several times in water to remove the caustic solution and transferred to fermenting vessels full of brine at typical ...
Olive oil quality is equally dependent on the quality of the olives themselves and on the time they have to wait from harvesting to extraction, in addition to the extraction method itself. The two main agents that cause the degradation of olive oil are oxygen and light. Once an olive is harvested, it should be pressed within 24 hours.
Since packaged foods last far longer, you won’t be surprised to learn that the biggest food spoilage challenges lie in fresh fruits and vegetables, animal proteins, dairy, and leftovers.
Within the EU (and other countries that ratified PDO agreements or similar laws), the name is protected with PDO status, which means that the name can only be used for olives (and olive oil) from the region around Kalamata.

How long: Freeze for 4 hours or until completely solid, then remove the cubes from the tray, transfer them to a zip-top bag, label, and aim to use within 2 months. Courtney West/Southern Living ...
These are labeled as "ripe" green olives that have been cured. [11] The process involves lye-curing in an oxygenated solution, that takes approximately 24 hours instead of six to eight weeks, and treatment with ferrous gluconate that fixes the black color. The olives are then placed in cans in mild brine, then pressured and heat processed. [12]
The last time the USDA released its plant hardiness map was in 2012. The temperature averages the USDA examined were between 1982-2012 versus the new map which averaged 1991-2020.
