Reusing cooking oil can help you save time and money on meal preparation, but it can also cause numerous health risks that outweigh its benefits. As the longest-running commercial biodiesel producer on the West Coast, SeQuential collects and recycles used cooking oil from thousands of restaurants and facilities from Portland, Oregon, to South El Monte, California, and the Los Angeles metro area. Here, we discuss the dangers of reheating cooking oil to help you keep your family or patrons safe.

Signs of Decaying Oil

Although it is ideal to use new oil with each meal preparation restaurants with deep fryers can typically reuse cooking oil three to four times. However, oil can deteriorate sooner, and you must dispose of it once it shows signs of decay. Indications that you should discard oil include:

  • Darkened color
  • Sour smell
  • Slower flow (viscosity) when poured
  • Loose sediment pieces at the bottom of the container or floating in the oil
  • Smoke appearing on the oil’s surface before the temperature reaches 375 degrees Fahrenheit or 190 degrees Celsius

Used Cooking Oil Is More Acidic

Customers or family members may complain of a burning stomach and throat after eating your cooked food. Reheated oil may be the cause of these sensations, as it is more acidic than fresh oil. Often, deep-fried and roadside food will produce a burning feeling. Using new cooking oil more frequently can combat this issue.
