How important is the sealing of olive oil cans?

1. Prevent oxidation
The influence of oxygen: Olive oil will gradually oxidize after contact with oxygen, resulting in a decline in quality, a worse flavor, and even the production of harmful substances. Well-sealed cans can effectively reduce the entry of oxygen and delay the oxidation process.
Sealing materials: High-quality sealing materials (such as silicone sealing rings) can ensure the sealing of the cans and prevent air leakage.
2. Maintain freshness
Extend shelf life: Well-sealed cans can significantly extend the shelf life of olive oil and maintain its freshness and flavor.
Prevent odor: Well-sealed cans can prevent external odors from entering and ensure the purity of olive oil.
3. Prevent leakage
Transport safety: During transportation, well-sealed cans can prevent olive oil from leaking and contaminating other items.
Storage safety: During storage, well-sealed cans can prevent olive oil from spilling and keep the storage environment clean.
4. Prevent microbial contamination
Prevent bacteria and mold: Well-sealed cans can prevent bacteria and mold from entering and ensure the hygiene and safety of olive oil.
Maintain hygiene: A well-sealed jar can reduce the entry of dust and impurities, maintaining the purity of olive oil.
5. Reduce volatility
Prevent volatility: The volatile components in olive oil will gradually evaporate when exposed to air, affecting its flavor and quality. A well-sealed jar can reduce volatility and maintain the aroma and flavor of olive oil.
