Properly storing deep fryer oil extends its lifespan and maintains its quality. To reuse your oil, follow these steps:
Straining the Oil
First, strain the used oil through a fine-mesh sieve lined with cheesecloth. This removes food particles and debris that can degrade the oil's quality and affect the taste of future fried foods. Several sources recommend this crucial first step.
Storing the Oil
After straining, store the oil in a sealed, light-proof container. This prevents oxidation and rancidity. Air exposure is a key factor in oil degradation.

Container Choice: Use a glass bottle or jar, as these are less likely to react with the oil than plastic containers. A stainless steel container with a tight-fitting lid is also a good option. Several products are specifically designed for oil storage, often including strainers.
-
Storage Location: Keep the container in a cool, dark place. The refrigerator is ideal for optimal oil preservation, and extending its usable life, potentially to up to six months according to some sources. If refrigerating, allow it to reach room temperature before reuse. If not refrigerated, storage for up to three months is recommended.
Oil Shelf Life and Reuse
While properly stored oil can be reused for several batches of frying, it's crucial to monitor its quality. Discard the oil if it becomes dark, smells rancid, or develops a thick, sludge-like consistency. Repeated heating degrades the oil, diminishing its frying capabilities and potentially impacting food safety.
