What Are The Benefits of Soybean Oil

What Is Soybean Oil?

Soybean oil is a kind of vegetable oil which is extracted from the soybean seeds. Today, according to the US agricultural services data information, it is one of the most widely used vegetable oils all over the world, possibly because soybeans are some of the most widely cultivated and utilized plants, particularly in recent decades. Soybean is native to East Asia and is considered a legume, however, despite its limited origin; it is highly prized for its edibility. Most soybean oil is refined, blended, and sometimes hydrogenated and it can be graded into different levels and strengths depending on the desired application. 

Soybean oil is considered healthier than most other vegetable oils, due to the presence of a good variety of essential fatty acids in it, which the body needs in order to remain healthy. There are also a number of plant sterols in soybean oil, which can have a wide variety of health benefits on people who regularly include soybean oil in their diet. The vitamin and mineral content of soybean is what fames this delicious and widely useful legume. Today, soybean is one of the widely cultivated commercial field crops grown in the U.S, Brazil, Argentina, China, and India. It is processed as fat free oil and made into many products such as soy milk, tofu, soy sauce, beans and granules that people consume for its many benefits.

Soybean Oil Production

The process of producing soybean oil needs several steps. First, the soybeans are first cleaned, dried and dehulled prior to oil extraction. The soybean hulls need to be removed because they absorb oil and give a lower yield. This de-hulling is done by cracking the soybeans and a mechanical separation of the hulls and cracked soybeans. Magnets are used to separate any iron from the soybeans. Then the soybeans are cracked, adjusted for moisture content, heated to between 60 and 88 °C (140–190 °F) by roasted, then put into oil press machine, rolled into flakes, and solvent-extracted with hexanes. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated are sold as "vegetable oil," or are ingredients in a wide variety of processed foods. Most of the remaining residue (soybean meal) is used as animal feed.

Soybean Oil Physical Characteristics

Dry soybean seeds compose about 18-20% of extractable oil by weight. The seeds are then subjected to pressing oil and the residue soybean meal is used as animal feed. Crude soybean oil is deep yellow and contains impurities such as moisture, lecithin, free-fatty acids, and certain volatile compounds. These impurities are then removed through further refining to obtain acceptable standard cooking oil. Refined oil is clear light yellow liquid, and features neutral odor and taste. Fresh oil has very low free fatty acids (FFA) less than 0.1%. Its specific gravity @ 25 °C is 0.9150–0.9280, Iodine value-75-94, and saponification value-184-195.

Soybean Oil Nutrition Facts

Soybean oil is one of the chief poly-unsaturated cooking oils. 100 g oil provides 884 calories.

It is one of the cooking oils with a high smoke point; 495 °F, similar to peanut oil. This property of soybean can be employed in setting oil at higher temperatures while deep frying.

Soybean oil has a very good lipid profile. It has saturated, monounsaturated and polyunsaturated (SFA: MUFA: PUFA= 16: 24: 58) fats in healthy proportions.

It is one of the stable cooking oils; having a long shelf life.

Soybean Oil Health Benefits

1. Good Cooking Medium: It is one of the healthiest oils that can be used for cooking. Soybean oil is rich in poly-unsaturated fats, omega-6 proteins and amino acid Linoleic acid. It is low in saturated fats and is voted as a great cooking medium by several doctors.
2. Inhibits Cholesterol Absorption: Soybean oil has sitosterol. This reduces the risk of contracting several health diseases. Consumption of soybean oil also helps avoid and inhibit the cholesterol absorption by the human body.
3. Delays Aging & Prevents Skin Problems: Soybean oil is rich in Vitamin E that is a lipid and an antioxidant. It helps keep the cell membrane intact. This ensures that the cell membrane and skin act as a barrier to harmful radicals, thus delaying aging and preventing skin problems.
4. Bone Health: Soybean oil is rich in Vitamin K, which helps in bone strengthening and bone formation. 5. Treats Alzheimer’s Disease: Vitamin K present in soybean oil helps prevent damage to the brain cells. Studies have proven that consumption of soybean oil in moderation can keep diseases like Alzheimer’s at bay.
6. Prevents Cancer: Soybean is said to help prevent cancer. It reduces the absorption of oxygen free radicals in the human body.
7. Treats Heart Related Conditions: Soybean has Omega-3 fatty acids. These play a vital role in reducing the risk of contracting cardiovascular diseases and arrhythmia.
8. Reduces Triglyceride Levels: Soybean oil and soybean food intake help reduce the triglyceride levels in the body.
