In a busy full-service kitchen, the fryer rarely gets a break. It handles everything from lunch rush appetizers to late-night comfort food, quietly carrying a significant share of the operation’s cost structure. Yet for many restaurants, fryer oil remains one of the most overlooked profit drivers. Each replacement, each wasted batch, and each shortened life cycle eats into margins that are already thin.
At Columbus Vegetable Oils, an 80-year-old family-owned manufacturer supplying foodservice operators nationwide, the focus is on helping kitchens get more out of what they already have. From storage to filtration to custom oil blends, the company finds that when you understand your oil, you protect your bottom line.
“Most common mistakes are exposure to oxygen and storage in areas with higher than recommended temperatures,” says Jermaine McClendon, director of quality oils, at Columbus Vegetable Oils. “Operators should always make sure their oil is stored in an air-tight container in a cool, dark place.”
Operators know bad oil when they see or smell it, but deterioration starts long before those warning signs appear. “Temperature, light exposure, and oxygen exposure are a few mechanisms that increase the oxidation of vegetable oils,” McClendon says. “Oxidation is what leads to breakdown and yields what we describe as rancidity—off flavor and off odor sensory notes.”
That chemical process does more than affect taste. It undermines consistency, making fry times unpredictable and batter results uneven. And because oil is one of a kitchen’s highest recurring expenses, early spoilage is money going up in smoke.
“Since oil is a significant recurring expense, it’s easy for operators to want to cut corners,” McClendon says. “To maintain the flavor, consistency, and appeal of your food, it’s best to keep to the basics—clean your fryers regularly and store your oils properly. In the long run, this will save you from unexpected costs like food waste and customer dissatisfaction.”
That back-to-basics approach has become a cornerstone of the company’s foodservice education efforts. Columbus Vegetable Oils, of course, sells oil, but the company also teaches operators how to extend its life through clean handling, correct temperature control, and scheduled filtration.

“A clean frying vessel is a key component,” McClendon says. “The rate of oxidation may increase with interaction with food components and residues. Be sure to keep a schedule for cleaning your fryers and properly disposing of used oil.”
Residue left behind from previous batches is one of the main culprits of rapid breakdown. When crumbs or proteins remain in the vat, they carbonize, creating particles that not only darken the oil but also act as catalysts for oxidation. Keeping the vat clean between cycles slows that process dramatically.
Filtration can double or even triple usable fry time when performed consistently. “Filtration can increase the life cycle of frying oils as you remove particles that no longer add value within the material,” McClendon says. “The frequency of filtration is subjective, dependent upon the desired attributes of the finished product. For example, when a flaky crust may be desired, you would want a more filtered, clean frying base, whereas crispiness may be achieved with several cycles of the same material.”
Fryer management is not one-size-fits-all. A seafood concept seeking delicate, golden coatings may filter more often than a steakhouse running heartier sides. The key is awareness—knowing what quality looks and tastes like for your brand, then setting maintenance routines that protect it.
Good oil management is both a kitchen policy and a culture shifter. Staff turnover, multiple shifts, and different cooks mean training must be repeatable and practical. Columbus emphasizes that education is just as important as equipment. “Understanding the fryer itself and desired product outcomes are key,” McClendon says. “Knowledge of how to clean and maintain the equipment, and frequency of these activities, is the foundation to successful application.”
Even the best oil cannot perform if people do not know how to treat it. The company encourages operators to standardize fryer-cleaning checklists and reinforce them in pre-shift meetings—an easy step that can prevent expensive mistakes later.
Columbus Vegetable Oils manufactures and packs one of the most comprehensive edible oil portfolios in the country—from canola, soybean, and sunflower to avocado and custom high-oleic blends. That depth gives operators more control over both performance and price.
“There is a wide variety of oils and blends to choose from. The key is to source highquality, stable oils,” McClendon says. “Oils with high oleic content would fall into this category. When considering blends, antioxidants—both natural and synthetic—have proven to perform well.”
High-oleic oils are prized for their stability. They resist oxidation, maintain color longer, and deliver a clean fry flavor that guests notice. For restaurants juggling multiple menu items such as hand-breaded proteins, fries, and vegetables, the right blend can minimize flavor carryover while reducing the number of oil changes each week.

Columbus backs that up with a research and development program capable of designing custom formulations for specific use cases. “Columbus provides high-quality products and the research and development capabilities to provide custom blends when required,” McClendon says. That means an operator can describe a challenge—such as faster breakdown in high-volume seafood frying—and the company’s lab can engineer a blend optimized for that environment.
Even the most diligent maintenance routine eventually reaches a limit. The trick is knowing when oil can be safely filtered and reused versus when it is time to start fresh. “Unfortunately, this is not an exact science, and will be dependent upon application,” McClendon says. “However, a few signs would be when the oil begins to lose its clarity, when you begin to notice accumulation of residue from prior fry cycles, and when your fry time becomes less efficient per cycle.”
That judgment call is easier with trained eyes in the kitchen. Regular visual checks, test fries, and consistent cleaning schedules help teams act before quality slips—a small, proactive habit that pays off with every plate that leaves the pass.
Beyond product supply, Columbus Vegetable Oils prides itself on accessibility. With facilities in Des Plaines, Illinois, and Reno, Nevada, the company serves operators across the U.S. with reliable freight options and responsive service. What stands out most is its collaborative approach. “Our expertise in understanding customers’ needs and processes uniquely positions us to match materials from our catalogue with end-user needs,” McClendon says. “Usually, all it takes is a brief conversation to move the operators towards the correct product. Our all-in approach to service and partnership speaks volumes.”
Extending oil life is not glamorous work. There are no marketing campaigns for fryer filtration or storage conditions. But in a business built on consistency and margins, these small operational details matter. Every extra day an oil performs, every batch that fries evenly, and every guest who leaves satisfied because their meal tasted the way it should—all of it adds up to real savings and loyalty. For operators, that is the recipe for both flavor and profit—when oil lasts longer, so does success.
