Jan 30, 2026
I. Determining Contamination of the Can Itself
1. Odor Check: A pungent, sour, or rancid odor persists even after cleaning.
2. Physical Condition: Cracks, gaps, or a damaged cap prevent proper sealing.
3. Sealing Failure: An aged inner stopper or a loose outer cap fails to prevent air leakage.
II. Determining Contamination of the Olive Oil Itself
1. Appearance Observation: Darkened color, cloudiness, sediment, or flocculent matter.
2. Smell: Rancid or sour odor.
3. Taste: Sour, bitter, or strange taste.
III. Impact of Storage Conditions
1. High temperatures, direct sunlight, or humid environments accelerate spoilage.
2. It is recommended to use within 3-6 months after opening.
IV. General Recommendations
1. Regular Inspection: Check the condition of the can and the oil every few months.
2. Prompt Handling: Immediately stop using the product and dispose of it properly if contamination is detected. 3. Proper storage: Store in a cool, dry, and dark place.
