Sunflower oil manufacturing process

Ingredients Used in the Sunflower Oil Manufacturing Process

The main ingredient in the sunflower oil manufacturing process is, of course, sunflower seeds. Other ingredients may include additives that improve the quality of the oil, but generally, the manufacturing process relies on the seeds’ natural properties to yield quality oil.

However, sunflower oil comes in different types, and the type depends on the kind of sunflower seed used. There are refined sunflower seeds and unrefined sunflower seeds. Both can yield different types of oils when subjected to different manufacturing processes.

As mentioned above, refined sunflower oil is extracted from refined sunflower seeds. On the other hand, unrefined sunflower oil is extracted from raw seeds.

Sunflower seeds have a high fatty acid composition. They include :

• Linoleic acid: This is the most abundant type of fatty acid in sunflower seeds. It’s an essential polyunsaturated fatty acid that has many health benefits.
• Oleic acid: This is a monounsaturated fatty acid that helps prevent heart diseases.
• Palmitic acid: This type of fatty acid is commonly found in plant oils and animal fats.
• Stearic acid: This fatty acid is mainly found in cocoa butter. It’s also prevalent in sunflower oil.

Commercial sunflower seeds used in the manufacturing process have a higher oil content. Typically, they range between 35% and 45%. This is compared to non-commercial seeds, which have around 24% – 30% oil content.

This high oil content makes the seeds an ideal ingredient for oil extraction.

Sunflower oil is usually extracted using two main methods. The first method is cold pressing, which is less effective in extracting oil. On the bright side, cold pressing retains the seeds’ nutrients. Therefore, the oil is more natural and healthier.

The second method is hot pressing (seeds are roasted before oil extraction). This method increases the oil yield but may compromise the oil’s nutritional value. Nevertheless, whether through cold or hot pressing, the quality oil that’s extracted is gold to manufacturers and suppliers.

How to Choose Sunflower Oil

Sunflower oil has two types, and each has a specific purpose. The first type is culinary sunflower oil, which is used in the kitchen for frying, roasting, and baking.

The second type is non-culinary sunflower oil. It’s used for body and hair moisturizing, making soap and candles, and massaging oils. Manufacturers and suppliers should note that sunflower oil for body use is recommended to have Vitamin E and other natural nutrients.

Besides nutrients, sunflower oil also comes in different textures and colors which affect the oil’s quality. When budgeting for nutritional sunflower oil, it’s critical to consider the oil’s degree of refinement. There’s refined oil, which is more versatile and has a longer shelf life. On the flip side, unrefined oil has a stronger flavor and is more perishable.

Oil quality is also affected by the oil extraction method used. Cold-pressed oil is more natural and healthier since it retains all the nutrients. Hot-pressed oil is more refined. Although refined oil is extracted, it usually has a higher yield.

Manufacturers and suppliers should also consider the oil’s smoke point when purchasing sunflower oil for frying at different temperatures. Oils with a higher smoke point are more suitable for high-temperature frying.

Organic oil is more natural and manufactured using organic farming practices. Therefore, it doesn’t have any synthetic or harmful chemicals. Although all sunflower oils have a golden to amber color, the oil’s color may also affect its quality.

Generally, the golden oil is more appealing to the eye and has a higher level of refinement than amber oil.

Steps in the Sunflower Oil Manufacturing Process

The sunflower oil manufacturing process involves several steps. They include:

• Seed selection: Sunflower seeds are carefully selected based on their quality and oil content. High-quality seeds with a higher oil yield are chosen for oil extraction.
• Cleaning: The selected seeds are cleaned to remove impurities. These include dirt, debris, and other seeds. Cleaning ensures that the oil produced is of high quality.
• Hull removal: Sunflower seeds have a hard outer shell or hull. It’s removed to access the inner kernel. This increases the oil yield during extraction.
• Shelling: After hulling, the seeds are shelled to produce small pieces called millet or particles. This process further prepares the seeds for oil extraction.
• Pelleting: The sunflower seed kernels are then ground into a meal. It’s compacted into pellets. This process increases the efficiency of the oil extraction process.
• Screw pressing: The meal or pellets are subjected to mechanical extraction using a screw press. The press applies heat and pressure to extract the oil from the sunflower seeds. Some manufacturers may use pre-pressing to extract a portion of the oil before the remaining oil is extracted through solvent extraction.
• Solvent extraction: Manufacturers use chemical solvents like hexane to extract the remaining oil from the seed cake. Hexane is preferred because it selectively extracts oil without significantly altering the meal’s protein content.
• Oil refining: Crude sunflower oil is then refined to remove impurities, waxes, and solvents. The refining process includes degumming, neutralization, bleaching, and deodorization. This improves the oil’s quality, stability, and shelf life.
• Packaging: The refined sunflower oil is then packaged in bottles, drums, or bulk containers for distribution. Proper packaging helps maintain the oil’s quality and prevents contamination.

Commercial Uses of Sunflower Oil

Sunflower oil is widely used and highly valued for its many benefits and versatility in various applications. It’s particularly loved in the food industry due to its neutral flavor and high smoke point.

Manufacturers use sunflower oil for frying, roasting, baking, and salad dressings. It’s a popular ingredient for creating margarine and spreads as well as frying oils and shortening. This is due to its light texture and mild taste, which don’t overpower the food.

Besides the food industry, sunflower oil is also prevalent in the cosmetics and personal care industry. It’s used in moisturizers, lotions, and creams because it’s a natural source of vitamin E. It helps nourish and hydrate the skin.

Similarly, sunflower oil is a common ingredient in hair care products such as shampoos, conditioners, and hair oils. Antioxidants in the oil help promote healthy hair and scalp moisturizing.

The oil’s emollient properties make it a good moisturizer that leaves the skin smooth and soft. This makes sunflower oil a popular ingredient for body oils and creams that help keep the skin hydrated.

Sunflower oil is also valuable in the industrial sector. Specifically for manufacturing biodiesel, lubricants, and greases. It offers an environmentally friendly alternative to petroleum-based products.

What’s more, sunflower oil cake, the byproduct of oil extraction, is used as animal feed. It’s a rich source of protein and other nutrients for livestock, poultry, and pets.

Sunflower oil is preferred for manufacturing pharmaceutical products such as ointments and capsules. Its light texture and hypoallergenic nature make it suitable for sensitive skin and medical formulations.

In agriculture, sunflower oil is used as a base for making pesticides and herbicides. And finally, the oil’s high levels of linoleic acid, oleic acid, and fatty acids that are good for health and help reduce cholesterol levels increase sunflower oil’s demand and popularity across various industries.
