A golden, heat-tolerant oil from the corn germ
Bulk corn oil is a long-standing favorite for frying and baking. It comes from the germ, the small, oil-rich heart of each corn kernel, and once refined it has a light golden color, a clean taste and a high smoke point. Many cooks find it gives fried food a slightly richer finish than other neutral oils.
Our corn oil is refined, bleached, deodorized and winterized, processed and packed in the United States from US-grown and imported corn germ, and supplied from 1-liter bottles to 20,000-liter flexitanks.
Why kitchens and food plants use corn oil
- High smoke point. Refined corn oil has a smoke point of about 230 °C (450 °F), well above normal frying temperatures.
- Winterized for clarity. Corn oil naturally contains waxes; winterizing removes them, so the oil stays clear in cold storage and in chilled products.
- Very low in omega-3. Alpha-linolenic acid is typically 2% or less, which makes corn oil more stable in the fryer than oils with more omega-3.
- Natural plant sterols and vitamin E. Corn oil is one of the richer common sources of phytosterols and tocopherols.
Frying with corn oil
Corn oil is widely used for frying chips, tortilla chips, snacks, chicken and fries. It holds up well in the fryer and its light golden color gives fried food an appealing finish. For the longest fry life in fryers that run all day, compare it with our deep frying oil and high-oleic sunflower oil.
How bulk corn oil is priced
Corn oil prices follow corn harvests, corn processing volumes and global vegetable oil markets. We price each order on grade, pack size, total volume and destination, and larger formats cost less per liter. The minimum is 1,000 liters per quote, and you can mix corn oil with any of our other oils.

Sourcing
From the corn germ to finished oil
Our corn oil is processed and packed in the United States from US-grown and imported corn germ. Corn oil is a co-product of corn milling: the germ is separated from the rest of the kernel, and the oil is recovered from it.
Every batch is refined, winterized, tested against specification and packed at our US facilities, giving you one quality standard and one point of contact for every order.

Processing
How we make corn oil

Germ separation
During milling, the oil-rich germ is separated from the starch and fiber of the corn kernel.
Pressing and extraction
The germ is conditioned and pressed, and the remaining oil is recovered.
Degumming and neutralizing
Gums and free fatty acids are removed for stability.
Bleaching
The oil is filtered through bleaching earth to remove color pigments and impurities.
Winterizing
The oil is chilled and filtered to remove natural waxes, so it stays clear when cold.
Deodorizing, testing and packing
Steam distillation under vacuum removes odor compounds; each batch is then tested and packed.
Storage & handling
Keeping corn oil fresh
Temperature
Store between 10 and 25 °C (50–77 °F), away from heat sources. Heat speeds up oxidation and shortens shelf life.
Light and air
Keep containers sealed and out of direct sunlight. Oxygen and light are the main causes of rancidity.
Shelf life
Up to 18 months unopened in original packaging. Transfer IBC and flexitank deliveries to clean, dry tanks and use them first-in, first-out.
In the fryer
Filter oil daily, skim debris, top up with fresh oil and avoid salting food over the fryer. Replace the oil when it darkens, foams or smokes at normal frying temperature.

FAQ
Corn Oil questions
What is the minimum order?
1,000 liters (about 264 US gallons) per quote, across any combination of oils and pack sizes. For example, one 1,000L IBC tote, five 200L drums, or 50 cases of 4 × 5L bottles.
Is your corn oil refined and winterized?
Yes. It is refined, bleached, deodorized and winterized, so it has a light golden color, a clean taste and stays clear when chilled.
Is corn oil good for deep frying?
Yes. Its high smoke point and very low omega-3 content make it stable in the fryer, and it is widely used for chips, snacks and fried foods.
Why is corn oil golden rather than pale?
Corn oil naturally carries more color than oils such as sunflower or canola, even after refining. A light golden color is normal for refined corn oil.
Can you supply non-GMO or identity-preserved oil?
Tell us in your quote request if you need non-GMO, identity-preserved or certified oil. Availability and certification depend on the crop lot, and we will confirm exactly what we can supply in your quote.
Where is your corn oil made?
It is processed and packed in the United States from US-grown and imported corn germ.
How is the price set?
Vegetable oil prices move with crop harvests and global commodity markets, so each quote is based on grade, pack size, total volume and delivery destination. Your quotation shows the price, any freight and other charges, the shipping terms and route, and an estimated arrival date.
