Product Quality and Characteristics
Raw Material Source:
Non-GMO corn from major corn-producing areas in Hebei Province is selected. After cleaning, hulling, and screening, the corn germ is preserved intact (approximately 10% of the corn weight, with an oil content of 80%), and moldy kernels are removed to ensure a single, traceable source of oil.
Pre-treatment Process:
- Washing and Dehulling: Removes surface impurities and separates germ from starch.
- Cooking and Low-Temperature Roasting: ≤100°C, softens germ tissue, improves pressing efficiency.
Oil Extraction and Refining:
- Pressing Method: Hydraulic or screw pressing, no chemical solvents throughout.
- Refining Process: Degumming (removes phospholipids), deacidification (neutralizes free fatty acids), decolorization (activated clay adsorbs pigments), deodorization (steam distillation removes odors).
- Nitrogen-filled packaging with light-proof packaging to extend shelf life.
Physicochemical Properties:
- Smoke Point: Approximately 232°C
- Linoleic Acid (Omega-6): 55%–60%
- Oleic Acid (Omega-9): 25%–30%
- Vitamin E (Tocopherols): 80–120 mg/100g
- Phytosterols: 0.8%–1.2%
- Acid Value: ≤ 0.5 mg KOH/g
- Peroxide Value: ≤ 2.0 mmol/kg
Physical and Sensory Characteristics:
The oil is a clear, light yellow liquid with a thin texture, free of sediment, and contains no added flavorings, preservatives, or colorings.
Usage-Related Characteristics:
High-Temperature Cooking: Suitable for frying, deep-frying, stir-frying, and other medium-high temperature cooking methods.
Nutritional Ingredients: Can be used in salads, pasta seasonings, and baking.
Healthy Diet: Rich in linoleic acid and phytosterols, it can be used as a supplement of essential fatty acids.
Health Benefits
1. Nutritional Advantages
High smoke point (above 230°C): Suitable for high-temperature Chinese cooking (frying), reducing the production of harmful substances.
Rich in unsaturated fatty acids:
Linoleic acid (55%-60%): Lowers LDL cholesterol, preventing cardiovascular disease.
Oleic acid (25%-30%): Regulates blood lipids, with anti-inflammatory and antioxidant effects.
Natural antioxidants:
Vitamin E (80-120 mg/100g): Anti-aging, protects cell membranes.
Phytosterols (0.8%-1.2%): Inhibits cholesterol absorption, reducing the risk of coronary heart disease.
2. Suitable for:
High-risk groups: Individuals with hypertension, high cholesterol, and high blood sugar.
Pregnant women and children (requires supplementation of essential fatty acids).
Fitness enthusiasts (zero cholesterol, low saturated fat).
3. Comparison with other cooking oils:
Compared to olive oil: Lower smoke point (190°C), more suitable for cooling; corn oil is more economical. Compared to peanut oil, corn oil has a milder flavor and a lower risk of causing allergies.

Frequently Asked Questions (FAQ)
Q: How can I tell if it is pure corn oil?
A: Check the package labeling, the ingredient list should only contain "corn germ oil"; recognize the non-GMO certification mark (such as the green food mark); clear and transparent at low temperatures, no sediment.
Q: Is pure corn oil suitable for frying?
A: Suitable. High smoke point (230°C) is much higher than frying temperature (180°C) and is so stable that it is still safe to use it 3-5 times repeatedly (but it is recommended to replace it regularly).
Q: How long is the shelf life? How to store?
A: 18 months unopened, use up within 3-6 months after opening; store in a cool place away from light, sealed, and away from high temperatures on the stovetop.
