Why is n-Hexane used for edible oil extraction?

Why is n-Hexane used for edible oil extraction?

The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-Hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. Unlike other solvents, hexane has certain properties that make it the ideal choice for oil extraction processes. Hexane can extract more oil from oilseeds compared to ethyl acetate and ether With its low boiling point, hexane can retain its liquid states even in cold climates.

The distillation range of n-Hexane is short, and the volatilization of harmful substances is relatively clean and thorough, so that the nutritional components of vegetable oil are not destroyed by high temperature, which improves the safety of edible oil, reduces the leaching consumption and residue of edible oil in production, has a high oil production rate, and is convenient for industrial scale production. Hexane is an organic solvent with good viscosity. It is usually used in rubber food, pharmaceutical, perfume, shoe making, adhesive tape, ball making, grinding, leather, textile, furniture, paint industries, or dilution, or cleaning solvent, or viscose.

In addition, it can also be used as a solvent for extracting seed oil (such as soybean oil, cottonseed oil, flax oil, peanut oil, safflower oil, etc.); It can also be used as a raw material for manufacturing polymers; Such as polypropylene and polyethylene.

Solvent extraction technology is a continuous edible oil extraction equipment, which uses the solubility of n-Hexane and oil to improve the oil content through soaking and spray. Solvent extraction technology can be used to extract oil from most oilseeds. The high oil content oilseeds such as rapeseed, peanut, cottonseed and sesame are extracted by pre pressing solvent, and the low oil content oilseeds are extracted by direct solvent.

Food grade n-hexane as solvent for vegetable oil extraction, food grade hexane in blue and red steel drums

Food grade n-Hexane as solvent for vegetable oil extraction

The main advantage of using n-Hexane as extraction solvent to prepare edible oil is low residual oil. In addition, there are eight advantages:

1. In the detection of the final edible oil products, the sulfur and benzene content in n-Hexane is very low, which is almost impossible to detect, and more in line with the international health detection standards.

2. The distillation range of n-Hexane is 63 ℃ – 71 ℃, and the dissolution rate is small.

3. The recovery temperature of n-Hexane is low and the energy saving effect is obvious. Moreover, it is of great benefit to improve the quality of oil products, and the color will be better. The acid value and peroxide in the oil can be reduced to improve the refining yield.

4. The content of n-Hexane is increased, the extraction capacity is improved, and the processing capacity of the device is also improved.

5. n-Hexane has good compatibility with oil and can reduce the residual oil in the filter cake. Increase the output of oil and improve the efficiency of enterprises.

6. The use of n-Hexane can reduce the drying temperature during the cake recovery process, reduce the direct steam supply, and thus reduce the dust intrusion of the condensation recovery system. Prolong the life cycle of the condenser.

7. Due to the extremely low sulfur content in n-Hexane, the corrosion of the system is reduced and the service life of the equipment is prolonged.

8. Reducing the operating system temperature after using hexane can reduce the reduction crystallization of unstable substances in the plant and improve the utilization rate of the whole system.

It can be seen from the above description that n-Hexane is the best choice in vegetable oil plants, which is also the reason why solvent extraction plants are becoming more and more popular in large vegetable oil production plants.

Hexane and oils work quite well together, which makes hexane an ideal solvent for oil extraction. Oil extraction requires fats to be soluble in a material, and hexane is a great match because it allows the oils to dissolve and separate from the original oilseed plant. The solvent extraction plant is the best solution for the project with a capacity of more than 30 tons / day. Because the residual oil amount is more than 5% for the press method and less than 1% for the solvent extraction method. The crude powder extracted by solvent extraction can be widely used in food raw materials with high protein content and high quality because of its low temperature.

We have the latest equipment and technology for the strict checking of raw material at the initial stage only. We ensure that prior to manufacturing the material is checked on the grounds of quality. As quality is our topmost concern, we give maximum priority to the stringent checking of the entire range of products. Junyuan Petroleum Group provides the food grade hexane for edible oil extraction and for pharma industries.

Uses of 2-Methylpentane (Isohexane)  

2-Methylpentane is employed as a raw material, rubber solvent and vegetable oil extraction solvent. It is also used as a solvent in adhesives. Further, it is used as an intermediate in organic synthesis and finds application in food, preservatives, cosmetics, pharmaceuticals, beverages and flavor enhancer.
Boiling Point: 61°C to 62°C
Density: 0.653
Flash Point: −40°C (−40°F)
Melting Point: 154°C
Hexane has been used for decades to extract edible oil from cottonseed. However, due to increased regulations affecting hexane because of the 1990 Clean Air Act and potential health risks, the oil-extraction industry urgently needs alternative hydrocarbon solvents to replace hexane. Five solvents,n-heptane, isohexane, neohexane, cyclohexane, and cylopentane, were compared with commercial hexane using a benchscale extractor. The extractions were done with a solvent to cottonseed flake ratio of 5.5 to 1 (w/w) and a miscella recycle flow rate of 36 mL/min/sq cm (9 gal/min/sq ft) at a temperature of 10 to 45°C below the boiling point of the solvent. After a 10-min single-stage extraction, commercial hexane removed 100% of the oil from the flakes at 55°C; heptane extracted 100% at 75°C and 95.9% at 55°C; isohexane extracted 93.1% at 45°C; while cyclopentane, cyclohexane, and neohexane removed 93.3, 89.4, and 89.6% at 35, 55, and 35°C, respectively. Each solvent removed gossypol from cottonseed flakes at a different rate, with cyclopentane being most and neohexane least effective. Based on the bench-scale extraction results and the availability of these candidate solvents, heptane and isohexane are the alternative hydrocarbon solvents most likely to replace hexane.

Edible Oil Extraction to Dominate the Market

  • Hexane is increasingly being used as a solvent to extract edible oils from seed and vegetable crops, e.g., peanuts, soybeans, corn, etc.
  • Hexane has a greater ability to extract oil, compared to other solvents, like petroleum ether and ethyl acetate. It easily mixes with vegetable oil and washes it out without disturbing fiber, protein, sugar, and undesired gums.
  • Growth in the edible oil segment can be attributed to the rising awareness among consumers about the use of refined oil and the impact it has on health.
  • According to the United States Department of Agriculture, the consumption of edible oils like soybean oil, in 2019, in the United States, was 10,659 metric ton and canola oil was 2,465 metric ton. Moreover, according to the Department for Promotion of Industry & Internal Trade, in India, the investment value in the vegetable oil sector, in 2019, was around INR 18 billion.
  • Additionally, the consumers are inclined to pay higher prices for healthy food products, owing to the increasing food-based health challenges, such as high cholesterol, obesity, etc.
  • The growing popularity of edible oils with added health benefits in many countries is shaping the purchase decisions of edible oils, which are high in omega 3, vitamins, oryzanol, natural antioxidants, and others. Thus, exhibiting the likely demand for edible oils in the forthcoming years.

Use of leaching solvent in preparing edible fat and oil

A leaching solvent used for preparing edible oils is characterized in that the solvent is applied to the leaching process of edible oil preparation so as to leach oil from materials. The solvent consists of the following components by weight ratio: 94 to 100 percent of isohexane, 0 to 3 percent of normal hexane and 0 to 3 percent of butane and pentane; the leaching process includes the following steps of: 1) leaching: the leaching temperature is 48 to 53 DEG C and a mass ratio between the materials and solvent is 1/1 to 0.8; mixed oil and leached wet meal are obtained; 2) desolventizing: the finished meal is obtained; 3) the evaporation of a first long-tube; 4) the evaporation of a second long-tube; mixed oil is obtained; and 5) steam stripping: raw oil is obtained. The solvent of the invention is mainly composed of isohexane so as to largely reduce the harm to the health of operators exposed in the manufacturing environment; the product quality can be enhanced and the protection to environment can be enhanced; the latent heat for the evaporation of isohexane is low and then the energy cost required by the solvent recycling can be effectively reduced.

Corn oil (maize oil) is oil extracted from the germ of corn (maize). Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil. It is also a key ingredient in some margarines. Corn oil is generally less expensive than most other types of vegetable oils.

Corn oil is also a feedstock used for biodiesel. Other industrial uses for corn oil include soap, salve, paint, erasers, rustproofing for metal surfaces, inks, textiles, nitroglycerin, and insecticides. It is sometimes used as a carrier for drug molecules in pharmaceutical preparations.

Global n-Hexane market dynamics 

Demand for n-Hexane, especially in developing region such Asia Pacific, is expected to boost the demand of the global n-Hexane market over the forecast period. Excellent properties of n-Hexane to remove odor and unwanted taste are expected to propel the demand of n-Hexane from the edible oil industry. n-Hexane has the ability to remove unwanted taste and odor and this is the precise reason that the demand for n-Hexane has increased in edible oil industry. However, the consumers from developed regions are shifting from refined oil to cold-pressed oil owing to its superior health benefits. Cold pressing is a natural way to produce oil which does not contain solvent residues, no preservatives with natural antioxidants. In addition, Isohexane, a hexane isomer is used as a substitute of n-Hexane in few oilseed extraction applications. Due to toxic nature of n-Hexane, it has been substituted by n-heptane in some pharmaceutical applications. This may retard the growth of the n-Hexane market.

Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty acids and removes color (bleaching). Final steps in refining include winterization (the removal of waxes), and deodorization by steam distillation of the oil at 232–260 °C (450–500 °F) under a high vacuum.

Some specialty oil producers manufacture unrefined, 100%-expeller-pressed corn oil. This is a more expensive product since it has a much lower yield than the combination expeller and solvent process, as well as a smaller market share.

After a 10-min single-stage extraction, commercial hexane removed 100% of the oil from the flakes at 55°C; heptane extracted 100% at 75°C and 95.9% at 55°C; isohexane extracted 93.1% at 45°C; while cyclopentane, cyclohexane, and neohexane removed 93.3, 89.4, and 89.6% at 35, 55, and 35°C, respectively. Each solvent removed gossypol from cottonseed flakes at a different rate, with cyclopentane being most and neohexane least effective. Based on the bench-scale extraction results and the availability of these candidate solvents, heptane and isohexane are the alternative hydrocarbon solvents most likely to replace hexane.

Edible Oil Extraction to Dominate the Market

  • Hexane is increasingly being used as a solvent to extract edible oils from seed and vegetable crops, e.g., peanuts, soybeans, corn, etc.
  • Hexane has a greater ability to extract oil, compared to other solvents, like petroleum ether and ethyl acetate. It easily mixes with vegetable oil and washes it out without disturbing fiber, protein, sugar, and undesired gums.
  • Growth in the edible oil segment can be attributed to the rising awareness among consumers about the use of refined oil and the impact it has on health.
  • According to the United States Department of Agriculture, the consumption of edible oils like soybean oil, in 2019, in the United States, was 10,659 metric ton and canola oil was 2,465 metric ton. Moreover, according to the Department for Promotion of Industry & Internal Trade, in India, the investment value in the vegetable oil sector, in 2019, was around INR 18 billion.
  • Additionally, the consumers are inclined to pay higher prices for healthy food products, owing to the increasing food-based health challenges, such as high cholesterol, obesity, etc.
  • The growing popularity of edible oils with added health benefits in many countries is shaping the purchase decisions of edible oils, which are high in omega 3, vitamins, oryzanol, natural antioxidants, and others. Thus, exhibiting the likely demand for edible oils in the forthcoming years.

Use of leaching solvent in preparing edible fat and oil

A leaching solvent used for preparing edible oils is characterized in that the solvent is applied to the leaching process of edible oil preparation so as to leach oil from materials. The solvent consists of the following components by weight ratio: 94 to 100 percent of isohexane, 0 to 3 percent of normal hexane and 0 to 3 percent of butane and pentane; the leaching process includes the following steps of: 1) leaching: the leaching temperature is 48 to 53 DEG C and a mass ratio between the materials and solvent is 1/1 to 0.8; mixed oil and leached wet meal are obtained; 2) desolventizing: the finished meal is obtained; 3) the evaporation of a first long-tube; 4) the evaporation of a second long-tube; mixed oil is obtained; and 5) steam stripping: raw oil is obtained. The solvent of the invention is mainly composed of isohexane so as to largely reduce the harm to the health of operators exposed in the manufacturing environment; the product quality can be enhanced and the protection to environment can be enhanced; the latent heat for the evaporation of isohexane is low and then the energy cost required by the solvent recycling can be effectively reduced.

Corn oil (maize oil) is oil extracted from the germ of corn (maize). Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil. It is also a key ingredient in some margarines. Corn oil is generally less expensive than most other types of vegetable oils.

Corn oil is also a feedstock used for biodiesel. Other industrial uses for corn oil include soap, salve, paint, erasers, rustproofing for metal surfaces, inks, textiles, nitroglycerin, and insecticides. It is sometimes used as a carrier for drug molecules in pharmaceutical preparations.

Global n-Hexane market dynamics 

Demand for n-Hexane, especially in developing region such Asia Pacific, is expected to boost the demand of the global n-Hexane market over the forecast period. Excellent properties of n-Hexane to remove odor and unwanted taste are expected to propel the demand of n-Hexane from the edible oil industry. n-Hexane has the ability to remove unwanted taste and odor and this is the precise reason that the demand for n-Hexane has increased in edible oil industry. However, the consumers from developed regions are shifting from refined oil to cold-pressed oil owing to its superior health benefits. Cold pressing is a natural way to produce oil which does not contain solvent residues, no preservatives with natural antioxidants. In addition, Isohexane, a hexane isomer is used as a substitute of n-Hexane in few oilseed extraction applications. Due to toxic nature of n-Hexane, it has been substituted by n-heptane in some pharmaceutical applications. This may retard the growth of the n-Hexane market.

Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty acids and removes color (bleaching). Final steps in refining include winterization (the removal of waxes), and deodorization by steam distillation of the oil at 232–260 °C (450–500 °F) under a high vacuum.

Some specialty oil producers manufacture unrefined, 100%-expeller-pressed corn oil. This is a more expensive product since it has a much lower yield than the combination expeller and solvent process, as well as a smaller market share.
