At SeedOilNews, we help people who are curious about seed oil by collating information and news about seed oils.

Aqueous oil extraction utilizes water as a solvent to extract oils from seeds or nuts, and requires expert knowledge in order to separate oil and water phases while also creating fine dust that necessitates special ventilation systems and equipment.
Solvent extraction is an efficient method for processing commodity vegetable oils. A range of solvents may be utilized, with hexane being the preferred choice due to its low boiling point and solubilizing properties.

What makes soybean seeds ideal for oil extraction?

Soybeans (Glycine max L) are legumes that produce vegetable oil, soybean milk, and tofu as staple food products. Soybean is one of the world’s most significant food crops. It is a source of protein for both humans and animals, providing food security to both. Furthermore, soybeans provide biodiesel production through various industrial applications.
Before soybeans can be used to extract oil, they must first undergo the steps of cleaning, drying, dehulling, and size reduction. Because hulls absorb oil and reduce yield, they must be removed – either manually by cracking the beans or by cracking and mechanical separation; heating is then done to coagulate proteins that contain oil within.
Soybean seeds are small and hard, and need to be properly prepared in order for them to be eaten. Once planted, these seeds rapidly absorb moisture – quickly growing from less than 13% moisture up to 50% in just days! This hydrates their seed coat while softening their internal embryo allowing the seed to sprout successfully.
Most oilseeds require size reduction prior to extraction in order to yield maximum oil yield from them. A size reduction mill consists of two cylindrical corrugated rolls arranged in series that rotate at different speeds to break apart seed cells containing oil; this labor intensive process is essential in producing top quality soybean oil.
Soybean oil is produced through a solvent extraction process using commercial hexane. Once in the extraction column, this evaporates away leaving crude soybean oil which then must be refined further to meet specific end use specifications.

What Makes Sunflower Seeds Ideal for Oil Extraction?

Sunflower seed oil is extracted from the seeds of Helianthus annuus sunflower plants, which are widely grown worldwide and known for their large yellow blooms that follow the sun as it moves across the sky. Sunflower seeds contain high concentrations of linoleic acid, which is considered healthy, possibly helping lower cholesterol levels and decreasing the risk of cardiovascular disease.
Sunflower seeds are harvested as soon as the plants begin flowering and processed into oil using either warm or cold presses, which greatly influences the taste of their final product. A warm press removes hulls from seeds before heating slightly before passing through steel rollers or piston-like cylinders to squeeze out oil; warm presses produce more refined oil, while cold presses produce natural and less processed products.
Before they are used for extraction, sunflower seeds must first be cleaned to remove foreign matter and dust, then de-hulled to separate their kernels from their husks to improve oil extraction and meal production. After being de-hulled, these prepared seeds are ground into coarse meal of appropriate consistency using hammer mills or grooved rollers before being passed over magnets to detect any trace metal contamination before it can be sent off for oil pressing.
Sunflower oil is considered “light” due to its concentration of monounsaturated fatty acids (MUFAs), which are more resistant to breakdown by heat or light than their polyunsaturated counterparts and offer greater stability under high-temperature cooking environments. Sunflower seed oil also boasts mild flavor while withstanding high-temperature cooking conditions and is an excellent source of Vitamin E; furthermore, diuretic and expectorant properties may help alleviate bronchial or laryngeal affections as well as whooping cough when made into an infusion form.

What Makes Canola Seeds Ideal for Oil Extraction?

Canola seeds (Brassica napus) are tiny black seeds that produce 35-45% oil, making it one of the healthiest vegetable oils available and one that has become a mainstay in many processed foods worldwide. Meanwhile, any remaining canola meal acts as protein-rich animal feed used around the globe.
Canola oil is produced by grinding up seeds into a paste and extracting their fat molecules with an organic solvent such as hexane. Once produced, this refined, bleached and deodorized canola oil is refined, bleached and deodorized for a lighter color and flavor product.
Conventional canola is grown worldwide for industrial uses and biodiesel production, which significantly lowers lifecycle greenhouse gas emissions by 90%. First bred in the 1960s, its genetic modification and other plant sciences have since enabled improved productivity more so than any other crop in existence.
Canola plants are part of the mustard family and closely related to cabbage and turnip crops. Their bright yellow flowers produce pods resembling pea pods containing tiny black seeds – known as canola seeds that boast high oil contents – making this crop one of Canada’s greatest success stories.
As canola seeds have a round shape that makes them difficult to process, flaking is the preferred solution to maximize oil extraction by pressing and solvent extraction processes by breaking up their round structure into pieces that can pass easily through equipment without rolling or hitting compression points in press machines. Next, they are heated in steam-heated cookers to rupture cells and further optimize viscosity; this preparation process is known as flaking and steam cooking/conditioning and helps maximize oil extraction from prepressing/solvent extraction processes.

What Makes Sesame Seeds Ideal for Oil Extraction?

Sesame seeds have long been prized as a nutritious source of oil for both culinary and medicinal uses for centuries. Sesame seed oil contains high concentrations of sesamol and sesaminol – two antioxidants with anti-inflammatory properties to combat cell damage – making sesame oil an excellent option when added to other food items as an ingredient or cooking oil.
Sesamum indicum, an annual plant native to China, India and Turkey that has become widely grown worldwide due to its delectable nutty taste, is responsible for producing these small seeds. After harvesting after a hot summer period the pods containing seeds are then hulled and crushed to release their oils for consumption.
Extraction of sesame oil requires heating the crushed seeds before pressing them to separate the oil from their nuts. Mechanical presses are typically used, though hexane-based solvent extraction increases yield but increases costs significantly, creating toxic byproducts during extraction.
Traditional African methods for extracting sesame oil involve heating ground sesame seeds in boiling water or adding them to hexane before evaporating to produce oil. Laboratory trials have demonstrated that oil obtained using this method compares favorably to that produced through bridge presses, with an extraction efficiency of 41% and leaving behind sesame cake with its high protein content suitable as animal feed.

What Makes Almond Seeds Ideal for Oil Extraction?

Almond seeds (Prunus dulcis) are the edible drupe of an edible tree called almond and are packed full of essential phytochemicals, fiber, vitamins, minerals, and healthy fats that support overall wellbeing. Almonds are especially high in vitamin E, which provides nourishment to skin against wrinkles and dark spots, while omega-3, three essential fatty acids, helps support heart health and prevent high cholesterol.
Almond oil, extracted from these seeds, is an integral ingredient in many skincare products that may help address dry skin, psoriasis, and eczema. You can use almond oil as massage oil, moisturizer, or facial wash, and as cooking oil. Cold pressing produces superior flavor as more beneficial fatty acids and antioxidants remain preserved than hot pressing methods of extraction.
Both methods for extracting oil from almonds start by cleaning and separating their seeds from their shells before warming and feeding them into a screw press to extract oil. Once complete, this resulting product, known as almond meal or press cake, can either be immediately used in further processing steps or stored.
Oil extraction from oil seeds often relies on using solvents such as petroleum benzin (also referred to as petroleum ether, commercial hexane or heptane) in order to dissolve and extract lipids from their meal, but this method has environmental toxicity issues; hence it has become essential that oilseed industry find alternative extraction processes which are less hazardous to our ecosystems.
