Description

LINSEED OIL MANUFACTURING SYSTEM, LINSEED OIL MANUFACTURING METHOD, AND LINSEED OIL

[0001] The invention relates to the agri-food sector. In particular, it relates to a system for manufacturing linseed oil intended for human consumption.

[0002] The invention further relates to a method for producing linseed oil. The invention also relates to a linseed oil.

[0003] Below we describe the known prior art from which the invention was developed.

[0004] Vegetable oils have been used for human consumption for many years. A vegetable oil is defined by the origin of its raw material(s) as being derived from an oleaginous raw material comprising lipids and not containing water. An oleaginous material can, for example, correspond to an oilseed, an oilseed nut, an oilseed almond or oleaginous fruit and / or their mixtures. Thus, there is olive oil, sunflower oil, rapeseed oil, grapeseed oil, palm oil or sesame oil for the best known and the various possible mixtures of vegetable oils.

[0005] Generally, vegetable oil can be obtained by grinding the raw materials so as to extract a first oil which is then kneaded in order to stop the emulsification which occurs. This is followed by an extraction step consisting of the separation of a solid or semi-solid phase comprising for example must / pomace / cake from a liquid or semi-liquid phase comprising the lipids. The extraction can be mechanical or chemical.

[0006] Mechanical or pressing extraction allows the production of a so-called pure oil from a single raw material (or virgin by cold pressing) containing no foreign substances, but the extraction is not complete and leaves lipids in the raw materials and therefore a loss of production. An additional step is often necessary to clarify the crude oil and obtain a pure and / or virgin oil. These oils have superior nutritional qualities to chemically extracted oils, but are often more expensive and can lead to significant production losses.

[0007] Solvent extraction (usually hexane) is the most widely used because it allows for more efficient extraction than mechanical extraction. However, traces of solvents are found in vegetable oils intended for human consumption. The resulting crude oil undergoes a purification step, generally by centrifugation, and refining. The oils are then bottled. Their nutritional qualities are often altered by the various treatments and manufacturing residues that persist in the resulting oil.

[0008] Furthermore, virgin oils are more sensitive to their environment than refined oils (air / light) which leads to rancidity, oxidation and a modification of their nutritional and organoleptic qualities (taste / odor) in addition to the difficulties linked to their extraction.

[0009] In particular, pure linseed oil (without any other raw material) for human consumption was banned from consumption until 2010, because its manufacturing process made it toxic and therefore unfit for consumption. Indeed, this particularly fragile oil (linked to the quantity of omega 3 fatty acid present) has a high sensitivity to oxidation, to rising temperatures and a very short shelf life (1 to 2 months). In order to limit the risk linked to oxidation, the packaging, storage and use requirements are more restrictive than for more traditional vegetable oils.

[0010] To improve their preservation, legislation has regulated their packaging, in opaque containers with a maximum capacity of 250 ml and storage in a refrigerated environment. Their bottling has also evolved to improve their preservation and reduce the risk of rancidity by requiring inert gas in the containers.

[0011] However, their manufacturing process always alters their nutritional and organoleptic properties as well as their shelf life. Indeed, although bottling is regulated, the manufacturing processes from seed to oil are much less so and each manufacturing stage is in contact with air and light, which promotes oxidation and rancidity of the oil even before being bottled. Furthermore, during the manufacturing processes, there is little control over the production chain and the points of vigilance are concentrated at the bottling stage. Also, it is not uncommon for the oil to undergo a rise in temperature during the press or subsequent stages of processing the crude oil (purification / centrifugation / filtration), which leads to deterioration or exposure to air, which further leads to oxidation.

[0012] Furthermore, flax seed extraction is particularly delicate due to the size of the flax seeds, the quantity required to produce oil in parallel with the high losses of lipids which cannot be completely extracted from the seeds without a high press temperature.

[0013] Furthermore, there is currently no solution to ensure that the consumer receives linseed oil with improved nutritional and organoleptic properties and an increased shelf life. In particular, there is no manufacturing process that can reduce or even avoid oxidation and rancidity throughout the production chain from seed to oil. Current processes only consider bottling, and the bottled oil is already partly oxidized, with a very short shelf life. In addition, current processes cannot guarantee optimized extraction to improve the production of linseed oil from flax seeds without deteriorating the linseed oil. Finally, there is currently no system that can meet these requirements.

[0014] Thus, there is a need for new manufacturing processes and systems for manufacturing linseed oil for human consumption that is non-toxic and has improved nutritional and organoleptic qualities. In addition, there is also a need for new manufacturing processes and systems for manufacturing linseed oil for human consumption with improved shelf life.

[0015] The invention aims to overcome the drawbacks of the prior art. In particular, the invention aims to propose a system for manufacturing linseed oil for human consumption, allowing the production of linseed oil for human consumption of improved nutritional and organoleptic quality. The invention also aims to propose a system for manufacturing linseed oil for human consumption in which oxidation and rancidity are reduced or even avoided during the production of the seed into oil. In addition, said system also makes it possible to improve the shelf life of linseed oil.

[0016] The invention further aims to provide a method for manufacturing linseed oil for human consumption, said manufacturing method making it possible to improve the organoleptic and nutritional qualities of linseed oil. The invention also aims to provide a method for manufacturing linseed oil for human consumption making it possible to reduce or even eliminate the risk of oxidation and rancidity in the supply of linseed to bottled linseed oil. In addition, this makes it possible to increase the shelf life of linseed oil.

[0017] The invention aims to overcome these drawbacks.

[0034] Below, we describe a summary of the invention and the associated vocabulary, before presenting the disadvantages of the prior art, and finally showing in more detail how the invention overcomes them.

[0035] In the remainder of the description, the term "rancidity" within the meaning of the invention may correspond to a strong odor and / or a pungent flavor deteriorating the organoleptic and nutritional qualities of linseed oil. Rancidity may be due to oxidation, hydrogenation, lipolysis.

[0036] The expression “organoleptic quality” within the meaning of the invention may correspond to properties perceived by the sense organs and preferably taste and smell.

[0037] The term "oxidation" within the meaning of the invention may correspond to a degradation of unsaturated fatty acids into saturated fatty acids upon contact with air, deteriorating the nutritional and organoleptic qualities of linseed oil. Oxidation may be due to air, but also to light and / or heat.

[0038] The expression "nutritional quality" within the meaning of the invention may correspond to the capacity of linseed oil to contribute to covering human food needs and in particular to the nutritional quality in terms of lipid profile (distribution, quantity, quality).

[0039] The invention proposes to take into consideration the problems of rancidity and oxidation during the production of linseed oil which deteriorate the nutritional and organoleptic qualities and reduce the shelf life. In particular, the invention proposes a system for manufacturing linseed oil intended for human consumption. For this, the invention proposes a new system for manufacturing linseed oil.

[0040] Thus, the invention relates to a system for manufacturing linseed oil for human consumption. A system for manufacturing linseed oil for human consumption may be illustrated in connection with the or the.

[0041] Laou 2 illustrates a system 1 for manufacturing linseed oil for human consumption, preferably pure linseed oil for human consumption and more preferably virgin linseed oil for human consumption.

[0042] A system 1 for manufacturing linseed oil intended for human consumption comprises at least one storage device 10, at least one extraction device 20, at least one decanting device 30, at least one bottling device 40, at least one source of inert gas 50.

[0043] At least one storage device 10 is preferably configured to store flax seeds from which flax oil can be produced. A manufacturing system 1 according to the invention is neither limited by the number of storage devices nor by their size or shape.

[0044] A storage device 10 may for example correspond to a hopper of the feed and / or loading hopper type. Preferably, a storage device 10 may be made of a corrosion-resistant and / or waterproof material. For example, stainless steel. This makes it possible, on the one hand, to preserve the flax seeds and, on the other hand, to improve the durability of the storage device.

[0045] Preferably, a storage device 10 is configured to comprise at least one suction device 12 and / or at least one dosing device and / or at least one flax seed processing device 14 and / or at least one sorting device and / or at least one ventilation device 15 and / or at least one hulling device.

[0046] Preferably, a storage device 10, and preferably a hopper, is configured to be arranged downstream of at least one suction device 12 and / or at least one dosing device and / or at least one flax seed processing device 14 and / or at least one sorting device and / or at least one ventilation device 15 and / or at least one hulling device.

[0047] At least one suction device 12 may be configured to transfer the loose flax seeds from a reservoir, preferably of loose flax seeds, to at least one storage device 10. A suction device 12 may, for example, correspond to a conveyor, preferably a pneumatic conveyor. Furthermore, a suction device 12 is preferably configured to be tubular with a circular cross-section. This makes it possible to limit the contact of the seeds with light from their first movement and even before entering the at least one storage device 10. Furthermore, a suction device 12 may be configured to cooperate, directly (without an intermediary) or indirectly (with at least one intermediary), preferably indirectly with the at least one storage device 10 and / or with at least one ventilation device 15.By intermediary is meant any element or device that can be configured to be arranged between the at least one suction device 12 and the at least one storage device 10. Advantageously, the cooperation being indirect, the system 1 for manufacturing linseed oil intended for human consumption may comprise at least one metering device, preferably for loose linseed, arranged between the at least one suction device 12 and the at least one storage device 10 and / or ventilation device 15. The at least one loose linseed metering device makes it possible, on the one hand, to meter the quantity of loose linseed in order to avoid clogging of the storage device 10 and / or the at least one extraction device and, on the other hand, to supply a predetermined quantity of loose linseed to the at least one storage device 10.A predetermined quantity can be determined based on at least one extraction and / or decanting and / or bottling device. A dosing device can correspond to a valve, a scale and / or a pump.

[0048] Preferably, the suction device 12 is configured to be arranged so that the transfer of the bulk flax seeds to the at least one storage device 10 and / or the at least one ventilation device 15 is subject to gravity. This makes it possible to reduce the resource requirement of the system 1. Furthermore, this allows a transfer by gravity and therefore to reduce the temperature of the manufacturing system and consequently to improve the nutritional and organoleptic qualities of the flax oil.

[0049] The manufacturing system 1 may also comprise at least one sorting device. A sorting device makes it possible to remove from the manufacturing system the impurities present (for example leaves and other residues which may be present), but also the flax seeds unsuitable for the manufacture of linseed oil. This makes it possible to improve the nutritional, organoleptic and hygienic qualities of the linseed oil, to preserve the system from malfunction, to reduce maintenance and the need for resources. A sorting device may for example correspond to an optical sorter.

[0050] The manufacturing system 1 may also comprise at least one device 14 for processing loose flax seeds, preferably sorted. A device 14 for processing loose flax seeds makes it possible to improve the hygienic quality. A treatment device 14 may correspond to a lamp, preferably of the UV type and even more preferably of the UVC type. Indeed, such a treatment makes it possible to avoid alterations to the pulp of the flax seeds. Advantageously, the flax seeds of the storage device 10 may have a quantity less than or equal to 20 cfu (colony forming unit) of E.Coli, preferably less than or equal to 15 cfu and even more preferably less than or equal to 10 cfu (measured by a technique known to those skilled in the art, for example by spreading on a petri dish and manual counting and / or by professional software).

[0051] The manufacturing system 1 may also comprise at least one ventilation device 15. A ventilation device 15 is preferably configured to be arranged above the storage device 10 in order to seal, preferably hermetically, the upper part of said storage device 10. This makes it possible on the one hand to limit exposure to air and light and therefore to seal the upper part of the storage device 10 and on the other hand to ventilate / dry the flax seeds in order to optimize the hygienic qualities of the flax seeds. A ventilation device 15 may for example correspond to a hood. Preferably, a ventilation device 15 comprises a vent, for example a vent. This makes it possible to purge the atmosphere from the storage device and to protect the storage device 10 against overpressure.

[0052] Indeed, a flax seed storage device 10 is further configured to cooperate with at least one inert gas supply 11. This surprisingly makes it possible to improve the nutritional and organoleptic qualities of the flax oil. In addition, this makes it possible to increase the shelf life of the flax oil. A supply 11 of inert gas may, for example, correspond to an injection port, making it possible to dilute the air contained in the flax seeds and / or the storage device to reduce the oxygen content and inert the inlet of the at least one extraction device 20. Furthermore, a supply of inert gas 11 may comprise at least one control and / or regulation means configured to control and verify the atmosphere and increase or reduce the gas flow rate of the supply of inert gas.A control and / or regulation means 51 may for example correspond to a manual, automatic or semi-automatic valve, a pump, and / or a valve.

[0053] Furthermore, a storage device 10 and / or a ventilation device 15 may be configured to cooperate with a tapping means 13. For example, a tapping means 13 makes it possible to take a sample of the atmosphere for analysis of the presence of oxygen. This makes it possible to check and control the atmosphere of the manufacturing system and in particular at the level of the at least one storage device 10 and / or the at least one extraction device 20. Indeed, the entire at least one storage device 10 and / or the at least one extraction device 20 is inerted with inert gas. This may also make it possible to protect the linseed oil against oxidation and rancidity. This makes it possible to improve the qualities of the oil, but also to increase its shelf life by maintaining an inert atmosphere since the seed supply.As a reminder, any contact with an atmosphere under air during the production cycle causes the benefits of inerting to be lost by oxygen uptake.

[0054] A flax seed storage device 10 is further configured to supply at least one extraction device 20. Advantageously, the storage device 10 is configured to cooperate with the at least one extraction device 20 directly or indirectly. By intermediary is meant any element or device that can be configured to be arranged between the at least one flax seed storage device 10 and the at least one extraction device 20. Thus, a storage device 10 is configured to supply flax seeds, preferably hulled, dried, sorted and / or treated, to at least one extraction device 20. Advantageously, the storage device 10 and the extraction device 20 are configured so that their cooperation is airtight. This makes it possible to reduce oxidation and rancidity.Furthermore, the storage device 10 and the extraction device 20 are configured such that their cooperation is light-tight. This reduces oxidation and rancidity. Furthermore, the storage device 10 and the extraction device 20 may be configured to cooperate by a flexible means, for example a flexible connector. This facilitates the transfer of flax seeds and reduces maintenance. Preferably, the storage device 10 is configured to be arranged upstream of the extraction device 20 and preferably above the extraction device 20. This allows the system to benefit from gravity and facilitate the transfer of flax seeds while reducing the resource requirements of the system.

[0055] Thus, a system 1 for manufacturing linseed oil intended for human consumption may comprise at least one extraction device 20. A manufacturing system 1 according to the invention is neither limited by the number of extraction devices, nor by their size or shape.

[0056] An extraction device 20 is configured to extract a crude oil from flax seeds.

[0057] An extraction device 20 may comprise a press, a screw extruder, a compression / extrusion head and / or a stop. Preferably, an extraction device 20 is configured to extract crude flaxseed oil cold. This makes it possible to improve the nutritional and organoleptic qualities of the flaxseed oil.

[0058] An extraction device 20 may comprise a manual and / or automatic mechanical variator with different speeds, for example from 10 to 70 revolutions / minute, with or without pressure. This makes it possible to adapt the speed of the device.

[0059] An extraction device 20 is preferably made of steel. This ensures the robustness of the extraction device 20 and improves its durability and therefore reduces maintenance. Preferably, an extraction device 20 is configured to be sealed. This improves the nutritional and organoleptic qualities of the linseed oil.

[0060] An extraction device 20 may comprise at least one sensor, preferably at least one temperature sensor, for example of the probe type, with or without a temperature regulator. This makes it possible to control the temperature of the extraction device which may overheat in the event of long-term use or high speed for example or the occurrence of malfunction(s). This makes it possible to monitor the temperature in order to avoid oxidation, hydrogenation and / or rancidity of the linseed oil. This thus makes it possible to optimize the nutritional and organoleptic qualities of the linseed oil as well as its shelf life.

[0061] An extraction device 20 may comprise a cooling device 21. Preferably, a cooling device 21 may be configured to cooperate with the extraction device 20 upon a temperature increase to a predetermined value. A cooling device 21 may correspond to fluidic cooling, preferably liquid.

[0062] A cooling device 21 may be configured to be arranged downstream of the at least one extraction device 20. This makes it possible to cool both the extraction device 20 and the linseed oil.

[0063] Furthermore, a cooling device 21 may be configured to cooperate with a tapping means 13. A tapping means 13 makes it possible to take a sample of the atmosphere for analysis of the presence of oxygen. This makes it possible to check and control the atmosphere of the manufacturing system 1 and in particular at the extraction device 20 and in particular at the cooling device 21. This makes it possible on the one hand to improve the qualities of the oil, but also to increase its shelf life by maintaining an inert atmosphere and on the other hand to ensure several control points of the system for manufacturing linseed oil intended for human consumption.

[0064] An extraction device 20 may be configured to cooperate with an inert gas supply (not shown), preferably a cooling device 21 is configured to cooperate with an inert gas supply. Preferably, an inert gas supply corresponds to an inert gas supply as previously described while being configured to cooperate with an extraction device 20.

[0065] The at least one extraction device 20 is configured to communicate with the at least one storage device 10 as previously disclosed. Furthermore, an extraction device 20 may comprise a return to the at least one storage device 10. For example, it may be a shunt. This makes it possible to avoid clogging of the extraction device and / or to provide additional safety in the event of a problem (temperature / speed / clogging) of the extraction device.

[0066] An extraction device 20 may be configured to comprise at least one liquid or semi-liquid outlet and at least one solid or semi-solid outlet. For example, an extraction device 20 may comprise at least one crude oil outlet and at least one cake outlet. Advantageously, a system 1 for manufacturing linseed oil intended for human consumption may comprise a cake storage means 22. This makes it possible to recover all of the products derived from the linseed. At least one extraction device 20 makes it possible to separate the oil, preferably the crude oil, from the cake. Advantageously, the cake may be recovered in the form of small compressed logs or pellets.

[0067] Thus, an extraction device makes it possible to obtain a “raw” quality vegetable oil below 37°C. For example, cold extraction, for example less than or equal to 20°C, preferably less than or equal to 15°C, preferably less than or equal to 10°C and even more preferably less than or equal to 5°C. An extraction device 20 is particularly versatile and makes it possible to satisfy different types of press, speed and temperature without changing equipment.

[0068] Furthermore, at least one extraction device 20 may be configured to communicate with at least one decanting device 30. Preferably, an extraction device 20 is configured to be arranged upstream of at least one decanting device 30 and preferably above at least one decanting device 30. This allows oil to be transferred by gravity and therefore reduces the resource requirement of the system 1. Furthermore, this makes it possible to reduce the temperature of the manufacturing system 1 and consequently improve the nutritional and organoleptic qualities of the linseed oil and its shelf life.

[0069] Thus, a system 1 for manufacturing linseed oil intended for human consumption may comprise at least one decanting device 30.

[0070] A decanting device 30 is configured to clarify the crude oil. A decanting device 30 makes it possible to clarify and / or purify the crude oil. This makes it possible to improve the nutritional, organoleptic and / or hygienic qualities of the linseed oil.

[0071] A decanting device 30 may comprise at least one decanting tank 32, preferably at least two decanting tanks 32, more preferably at least three decanting tanks 32, more preferably at least four decanting tanks 32. A decanting device 30 may comprise at most ten decanting tanks 32. A decanting tank 32 makes it possible to participate in the decanting and purification of the crude linseed oil so as to obtain a clarified or pure linseed oil.

[0072] A decanting device 30 may comprise at least one buffer tank 33. A decanting device 30 may comprise at most three buffer tanks 33. A buffer tank 33 makes it possible to participate in the decantation and purification of the linseed oil. A buffer tank 33 makes it possible to participate in the storage of the linseed oil. A buffer tank 33 makes it possible to participate in the transfer of the crude and / or clarified linseed oil.

[0073] A decanting device 30 may comprise at least one storage tank, preferably at least one crude oil storage tank 34. A decanting device 30 may comprise at most three crude oil storage tanks 34. A crude oil storage tank 34 makes it possible to store the crude oil.

[0074] A decanting device 30 may comprise at least one storage tank, preferably at least one pure oil storage tank 35. A decanting device 30 may comprise at most three pure oil storage tanks 35. A pure oil storage tank 35 makes it possible to store the pure oil.

[0075] A decanting device 30 may comprise at least one decanting tank 32 configured to be arranged between an extraction device 20 and a buffer tank 33. A buffer tank 33 may be configured to be arranged between a decanting tank 32 and a storage tank 34, 35. A storage tank 34, 35 may be configured to be arranged between a buffer tank 33 and at least one bottling device 40.

[0076] In an embodiment comprising several settling tanks 32, each settling tank may be configured to preferably communicate fluidly with the next settling tank. Preferably, each settling tank 32 comprises a dip tube, for example configured to provide fluid communication between at least two settling tanks.

[0077] Furthermore, at least one settling tank 32 is configured to communicate with at least one extraction device 20. At least one settling tank 32 is configured to communicate with at least one buffer tank and / or one storage tank. A buffer tank is configured to communicate with at least one settling tank and / or at least one storage tank. A storage tank is configured to communicate with at least one buffer tank 33 and / or with an extraction device 20, for example by means of a feed 23. A storage tank, preferably a pure oil storage tank 35, is configured to communicate with a bottling device 40.

[0078] A tank can be configured to include a sealed material, such as stainless steel. This helps ensure the nutritional, organoleptic, and hygienic qualities of the oil. It also reduces maintenance of the manufacturing system.

[0079] A decanting device 30, and preferably each tank of the decanting device 30, may be configured to include a safety means. Preferably, a safety means may correspond to a high and / or low level detector. This ensures the proper operation of the manufacturing system. Furthermore, a safety means may be configured to communicate with an extraction device 20. This improves the safety of the manufacturing system 1.
