Definitions
- the invention relates to a sensorially appealing protein preparation from hemp seeds as an ingredient for food, pet food and animal feed, and a method for obtaining such hemp protein ingredients.
- soybean proteins which can be mixed with soybean and pea proteins as a blend component in order to compensate for the methionine deficit in these protein preparations. This can be achieved, for example, with proteins from oilseeds.
- a cost-effective source of protein for food, feed and pet food is the pressing and extraction residues from the extraction of edible oil from hemp seeds.
- Hemp seeds have a firm husk with predominantly dark green and brown pigmentation and contain an oily pulp.
- the shells have not been completely or largely separated to date, as they have a considerable deterioration of the oil yield and speed of pressing would result.
- the seeds are used without peeling or partially peeled with a peel content of significantly more than 10% by mass, usually more than 20% by mass, when pressing to obtain hemp oil.
- press cakes with an oil content of less than 15% by mass, in many cases less than 10% by mass are then obtained. These can be ground into a powder and added to food and animal feed. Due to the harsh treatment at high temperatures, the techno-functional properties such as the gelation of the protein are inferior. In addition, the high shell content leads to a green-brown color of the press cake, which reduces acceptance in food applications. Due to the content of unsaturated fatty acids, the oily press cake also tends to oxidize the residual fat, which very quickly impairs the sensory properties during storage.
- hemp preparations In comparison to isolates from soya (protein content >90%) or pea (protein content >80%), such hemp preparations also only have a protein concentration below 60% by mass, sometimes even significantly below 50% by mass (cf. e.g. Potin et al., "Hemp (Cannabis sativa L.) Protein Extraction Conditions Affect Extraction Yield and Protein Quality", Journal of Food Science 2019,
- hemp preparations are known whose fat content is reduced to values below 2% by mass after pressing using supercritical CO2, which improves their storage stability.
- this method causes very high costs.
- the extraction takes place at high pressure of several 100 bar in very expensive plants, the production and operation of which are associated with high CO2 emissions. Since the process requires a lot of energy and large amounts of CO2 are released from the de-oiled flour after expansion, protein flours extracted using supercritical CO2 have no clear ecological advantages compared to animal proteins and also cause similarly high costs for the provision.
- the object of the present invention was to provide a neutral-tasting, light-colored and high-quality plant-based protein preparation and a cost-effective method for producing it, which is suitable for color-demanding food applications such as plant-based dairy alternatives (drinks, yoghurt, cheese) or light-colored plant-based meat, Poultry meat or fish alternatives are suitable.
- the preparation should advantageously have as high a protein content as possible in order to contribute to protein enrichment in foodstuffs even when used in small quantities, or to compensate for the deficit in methionine even in small doses when mixed with legume protein.
- the raw material used for the production of the protein preparation according to the invention is cleaned and partially or completely peeled hemp seeds, which have a hull proportion of less than 18% by mass, better less than 10% by mass, advantageously less than 5% by mass, based on the raw material mass. even better less than 2% by mass, particularly advantageously less than 1% by mass.
- the preparation according to the invention is characterized by the following properties (the methods of determination are given at the end of the description):
- the fat content of the preparation is less than 6% by mass, advantageously less than 4% by mass, better less than 3% by mass, particularly advantageously less than 2% by mass, in each case based on the dry matter or dry substance (TS) of the preparation .
- the protein content of the preparation is greater than 65% by mass, advantageously greater than 70% by mass, better greater than 75% by mass, particularly advantageously greater than 80% by mass (based on
- the preparation is light to white in color both in dry form and in aqueous suspension, the L* value after grinding to a particle size d90 (d90: proportion of 90% by mass of all particles smaller than the specified value) below 250pm greater than 70, advantageously greater than 80, better greater than 90, particularly advantageously greater than 92.
- the L* value for a 10% aqueous suspension is greater than 70, advantageously greater than 80, better still greater than 90, particularly advantageously greater than 92 (see Table 1).
- the preparation has a residual hull content of the hemp seeds of less than 36% by mass, better less than 20% by mass, preferably less than 10% by mass, particularly preferably less than 4% by mass or less than 2% by mass. -% on.
- the preparation contains a proportion of water-soluble carbohydrates. Since sucrose makes up the largest proportion of water-soluble carbohydrates, these are given below as the sucrose content.
- the sucrose content is less than 8% by mass, advantageously less than 3% by mass, better less than 1% by mass, particularly advantageously less than 0.65% by mass.
- the preparation has an ash content (based on TS, after treatment at 550° C.) of more than 5% by mass, preferably more than 10% by mass, particularly advantageously more than 15% by mass. This shows that the proportion of carbohydrates is very low. Thus, preventing the formation of gels in food due to high proportions of carbohydrates and roughage can be largely avoided.
- the particle size of the preparation has a d90 value of less than 500 gm, better less than 250 gm, advantageously less than 150 gm, particularly advantageously less than 100 gm.
- the preparation has techno-functional properties, in particular an emulsifying capacity greater than 125 mL/g, advantageously greater than 200 mL/g, better greater than 300 mL/g, particularly advantageously greater than 400 mL/g.
- the preparation has a protein solubility of between 8% and 50%, advantageously between 9% and 20%, particularly advantageously between 9% and 15%.
- preparations according to the invention are extremely suitable as an ingredient for extruded plant proteins, e.g. as a wet-textured meat substitute or dry texturate.
- the preparation contains alcohol, in particular ethanol, greater than 0.001% by mass, better than >0.01% by mass., advantageously >0.1% by mass, particularly advantageously >0.4% by mass but in each case less than 1% by mass. This shows that even with a content of 0.5% by mass, the functional properties of the preparation are at a very high level.
- the preparation contains proportions of hexane greater than 0.0005% by mass, better >0.001% by mass, but less than 0.005% by mass. Preparations with such hexane levels exhibit better functional properties compared to lower hexane level preparations.
- Table 1 Color values for the hemp protein preparation of the exemplary embodiment as flour and in a 10% suspension
- solvent-containing preparations still show very good properties in terms of technical functionality at the specified levels of solvent, such as very good texturing in the extruder with the formation of solid gel structures, although the protein content is in the same order of magnitude as protein isolates (such as pea protein isolates), which in the presence of solvents such as ethanol show a significant loss of functionality.
- the preparation has additional properties that can be of great use in different food applications. For example, the content of the sucrose originally contained in the seeds can be reduced after the use of suitable processes, so that the ratio of proteins to soluble carbohydrate content in the protein preparation is significantly higher than in dehulled hemp seeds.
- the hemp protein preparation according to the invention in this case also sucrose-reduced, is particularly suitable for the production of light-colored foods such as plant-based dairy, poultry or fish alternatives, where the consumer expects a light color.
- the method according to the invention has several sub-steps, in which cleaned hemp seeds are freed from shells and seed coats or correspondingly cleaned and shelled hemp seeds are provided, then mechanical de-oiling, preferably with a continuous or quasi-continuous press, such as a screw press, an extruder or a hydraulic press, are subjected to the obtained press cake or partially de-oiled hemp seeds then by means of solvent extraction using alcohol and water, in particular mixtures thereof, or hexane and water, advantageously after setting a defined particle size and setting a defined water content of the press cake or the partially de-oiled hemp seeds largely from oil and Sucrose to be freed. The solvent or solvents are then separated from the preparation.
- a continuous or quasi-continuous press such as a screw press, an extruder or a hydraulic press
- the preparation is preferably ground to a defined particle size distribution.
- the process can advantageously be accompanied by sieving, classifying and sorting processes that enable parts of the shells and seed coat to be separated before, during or after processing the seeds.
- the partial steps of the proposed method are explained in more detail below.
- Cleaning In a first step, cleaned hemp seeds are provided or foreign matter such as stones, straw, foreign grains or other contaminants are removed from hemp seeds using mechanical processes. The proportion of trimmings is reduced to less than 0.5% by mass, advantageously less than 0.2% by mass, better less than 0.1% by mass, particularly advantageously less than 0.05% by mass, or it hemp seeds are provided with a correspondingly low percentage of stock.
- Shelling In the next step, the cleaned hemp seeds are shelled or shelled hemp seeds are provided. After peeling and before further processing to achieve the color of the preparation according to the invention, the proportion of shells and seed coats is less than 18% by mass, preferably less than 10% by mass, advantageously less than 5% by mass, better less than 2% by mass, particularly advantageously less than 1% by mass. Even if this extensive separation of the shell makes pressing, as the preferred form of mechanical partial deoiling, very difficult, this step creates the basis for the finished preparation to achieve a lightness value L* of over 90. Sorting is also preferably performed as part of the dehulling step to separate individual (darker) seeds or remaining hull fractions from the flow of dehulled seeds by air blast or suction.
- the oil is mechanically separated from the seeds, advantageously with continuous devices for de-oiling
- continuous devices for de-oiling examples of such aggregates are presses such as screw presses, extruders or quasi-continuous hydraulic presses, but other mechanical devices for oil separation such as centrifugal separation techniques can also be used.
- the pressing is carried out in such a way that the residual oil content after pressing is greater than 8% by mass but less than 40% by mass; the residual oil content is advantageously between 8 and 30% by mass, better between 8 and 25% by mass and particularly advantageously between 8 and 20% by mass.
- the lower limit of 8% by mass of residual oil content is chosen because further oil separation requires significantly higher temperatures, which can contribute to damage to the proteins.
- Shelled hemp seeds have a high oil content of up to 60% and are not easy to mechanically de-oil due to the lack of shells for drainage.
- attempts will be made to achieve a residual oil content of less than 20% by mass in the press cake after pressing or in the partially de-oiled hemp seeds. It may therefore be necessary to press the press cake again with a press or to carry out another mechanical partial de-oiling. This can be done during pressing, for example, by adding the press cake to the inlet of the first press together with unpressed seeds, or in a further second press, which only further de-oils the press cake.
- the press cake can also be pressed several times in order to achieve the desired residual oil content.
- the desired low residual oil content can be achieved without having to set temperatures that are too high.
- pressing or mechanical partial de-oiling takes place at moderate temperatures.
- the hemp seeds are pressed or partially mechanically de-oiled at an average temperature below 100°C, advantageously less than 80°C, better still less than 60°C.
- the mean temperature is understood to be the arithmetic mean of the temperature of the seeds in the intake and the temperature of the press cake or the partially de-oiled hemp seeds at the outlet of the press or the device for mechanical partial de-oiling.
- the seeds before the mechanical partial deoiling, are conditioned by adjusting the temperature and humidity of the seeds.
- the water content in the seeds is adjusted to between 2 and 8% by mass, better between 3 and 6% by mass, particularly advantageously between 4 and 5.5% by mass, and the temperature to values between 30° C. and 80 °C, advantageously between 40 and 60°C, particularly advantageously between 45°C and 55°C.
- Optional pre- or intermediate cooling In a further embodiment of the method, the seeds before or during the mechanical pre-treatment (consisting of peeling, sorting, pressing or mechanical partial de-oiling) to a temperature below 20 ° C, advantageously below 10 ° C, better below 0°C, even better below -10°C, particularly advantageously below -15°C. It turns out that by lowering the temperature, the mechanical steps such as peeling and sorting can be carried out more easily, so that the yield in the process can be increased, for example by reducing the losses of already peeled hemp seeds when blowing out during sorting or the seeds not form such large deposits on the system parts. In addition, after lowering the temperature, there can be significant quality improvements due to less lipid oxidation come.
- Cooling tunnels can be used to cool the seeds, or the seeds can be cooled with cold air, cold inert gas or liquid nitrogen.
- Optional conditioning of the press cake or the partially de-oiled hemp seeds Before further processing to separate the remaining oil and to reduce the proportion of sucrose from the press cake or partially de-oiled hemp seeds, in an advantageous embodiment of the method according to the invention, the press cake or of the partially de-oiled hemp seeds. It turns out that lowering the moisture in the press cake or the partially de-oiled hemp seeds, which can be up to 15% by weight after mechanical partial de-oiling, to a residual moisture content of less than 8% by weight, advantageously less than 5% by weight , better less than 3% by mass, particularly advantageously less than 2% by mass, e.g. with the help of dryers, which makes de-oiling using organic solvents more efficient in the subsequent step, since more oil can be separated with less solvent at lower moisture levels. This can be used advantageously to reduce costs and contribute to protecting the proteins.
- the press cake or the partially de-oiled hemp seeds are comminuted to particle sizes with a d90 value of less than 2 mm, advantageously less than 1 mm, better less than 0.5 mm, particularly advantageously less than 0.2 mm, during the drying and extraction process significantly accelerated.
- This acceleration leads to an improvement in the functional properties in the preparations, since the dwell time in the dryer and the Contact time between solvent and proteins is shortened.
- the proportion of fines with a particle size of less than 100 ⁇ m in the comminuted bed of press cake or hemp seed should be less than 50% by mass, advantageously less than 25% by mass, particularly advantageously less than 10% by mass.
- the flake thickness is advantageously set to less than 2 mm, preferably less than 0.5 mm, particularly advantageously less than 0.2 mm.
- Flake thickness is understood to mean the average thickness of the particles emerging from the roller mill or another flaking unit. The average thickness can be determined, for example, by measuring with a caliper or a micrometer screw, it then corresponds to the average of 50 measurements.
- the particle size and shape of the press cake in mechanical partial de-oiling with a press can be adjusted using different methods. Mills or crushers with appropriate sieve inserts or roller mills with defined roller spacing can be used. In this way, particle size distributions with a defined size spectrum can be obtained. These can be equalized after or during the grinding by separating them according to size, for example by means of sieving, with regard to the particle size distribution.
- Fast-flowing liquids in the form of a pressure jet or suspensions containing solids can also be used to crush the press cake particles.
- conveyor units, stirrers or mixers with a shearing load on the press cake can also be used.
- aggregates that are already used in the process for conveying the extraction agent are also used for this purpose. This makes it possible to use aggregates for the comminution that actually are designed for pumping or stirring, such as
- Centrifugal pumps or other forms of conveying units or agitators By means of a suitable residence time in these units or by circulation, it will be possible to set the comminution in the devices mentioned in such a way that the particle size distribution according to the invention is obtained.
- Solvent extraction For the separation of residual oil and sucrose from the press cake or mechanically partially de-oiled hemp seeds, mixtures of alcohols with water are preferably used as solvents. Combinations of alcohol as one solvent and water as the other solvent can also be used. The use of alcohol or hexane, in each case with the presence of water, is also possible.
- the treatment with the organic solvent and the treatment with water can take place simultaneously in the same extraction step (e.g. in the form of an alcohol-water mixture) or can be arranged one after the other. Alcohols such as ethanol, propanol, isopropanol or others can be used.
- the proportion by mass of organic solvent relative to the mass proportion of press cake or partially de-oiled hemp seeds should be greater than 1.5 to 1, advantageously greater than 3 to 1, preferably greater than 5 1, even better greater than 7 to 1, particularly advantageously greater than 10 to 1 can be selected. In this way, a far-reaching reduction in oil to below 2% by mass and a reduction in sucrose to below 1% by mass can be achieved.
- the water content in the extraction is selected to be greater than 6% by mass, advantageously greater than 7% by mass, particularly advantageously greater than 8% by mass, better still greater than 10% by mass.
- the water content should be greater than 6% by mass but less than 14% by mass in order to prevent the oil from being able to be adequately dissolved. This limitation makes it possible to obtain a techno-functional protein preparation that has a particularly light color and a very high protein content.
- the water can be added to the organic solvent by providing water-containing solvent, for example an alcohol-water mixture, by adding sufficiently moist press cake or moist hemp seeds or by adding water directly before or during the solvent extraction. Combinations of the measures mentioned can also be selected.
- water-containing solvent for example an alcohol-water mixture
- the temperature of the solvent during the extraction will be between 30°C and 75°C, advantageously between 45°C and 65°C, particularly advantageously between 50°C and 65°C. At this temperature, the selected mixtures of water and organic solvent are able to separate both oil and sucrose from the hemp seeds without causing excessive denaturation of the proteins at the same time.
- the duration of contact between organic solvent and the press cake or the protein preparation at temperatures above 45° C. is between 30 minutes and 12 hours, advantageously between 1 hour and 5 hours, particularly advantageously 1 to 2 hours.
- the temperature ranges mentioned above should also be selected if hexane is used in order to largely avoid thermal damage to the proteins.
- a conventional percolation extraction can be used for the extraction, in which the solvent flows over a bed of press cake particles or particles that have been conditioned with regard to particle size/shape or moisture, so that oil and sucrose are discharged into the organic solvent or can take place in the water. Since fine particles are detached from the hemp press cake during this process and can be discharged with the solvent, extensive filtration devices must be provided in order to avoid clogging of pumps and pipes or loss of product. In order to prevent or at least limit this process, it can be advantageous to press the conditioned or unconditioned press cake into pellets before extraction, from which significantly fewer fine particles are released during extraction. As a result, the effort for filtration can be significantly reduced.
- Percolation extraction cannot be completely avoided, it is advantageous to carry out an immersion extraction preferably, for example, in a mixing-settling process.
- a multi-stage immersion extraction is particularly advantageous.
- the press cakes or the conditioned press cakes are completely immersed in the solvent.
- an immersion extractor it is possible to crush the particles simultaneously with the extraction, as described above, using a stirrer. This also makes it possible to gradually crush the press cakes in perform several extraction vessels arranged one behind the other.
- solvent and raffinate can be separated mechanically, advantageously by sedimentation. The oil-containing miscella in the supernatant can then be distilled and rectified and the recovered solvent can be used again for the extraction of press cake particles with a finer particle size distribution.
- the press cake (raffinate) that has been separated from the solvent can be mixed with fresh solvent and thus be de-oiled again.
- the excess solvent from the treatment of a raffinate loaded with less oil can be used again for the extraction of a raffinate loaded with more oil to reduce the total amount of solvent, and so on.
- a countercurrent extraction can also be implemented in a screw, chamber or belt extractor.
- a particular advantage of using sedimentation results from the possibility of setting the sedimentation time for setting the solid-liquid separation shafts.
- a sedimentation takes place in the earth's gravity field up to a defined volume ratio of raffinate and supernatant.
- This process can advantageously be supported by a filter or sieve bottom that accelerates or sinks the sedimentation of the particles from above or by applying a vacuum below a filter below the sedimentation layer (e.g. nutsche).
- a vacuum below a filter below the sedimentation layer e.g. nutsche
- the raffinate In countercurrent, the raffinate can again be charged with solvent and the suspension is stirred until due The shear during stirring sets a new particle size distribution. The sedimentation process then takes place again.
- the process of mixing and settling the raffinate can be repeated several times; the process is advantageously carried out more than 2 times, better more than 3 times, particularly advantageously more than 4 times, so that the extraction is particularly advantageously carried out as a multi-stage extraction in countercurrent becomes.
- the water content can be lower to make de-oiling more efficient, since, for example, a solvent such as ethanol or propanol with less water can dissolve more oil.
- a solvent such as ethanol or propanol with less water
- this procedure also has the advantage that the water content is only high for a short time in the first extraction stage, so that protein denaturation can be minimised. It has been shown that denaturation of the proteins in hemp seeds can be reduced if solvents or solvent mixtures with different polarities are used in different extraction stages.
- Post-treatment and desolventization of the preparation Following the extraction with the organic solvent(s). and water, the preparation can optionally be further treated with aqueous enzyme solutions or by fermentation or dried directly to improve the functional properties. Drying is advantageously carried out at low temperatures below 120° C., better below 100° C., particularly advantageously below 80° C., in order to protect the proteins and to keep the color of the preparation as light as possible.
- a dryer that can be operated in a vacuum and whose pressure is reduced again at the end of the drying process to separate the solvent residues is advantageously used for this purpose.
- the pressure is reduced to values below 500 mbar, better below 200 mbar, particularly advantageously below 100 mbar. This reduction in pressure at the end of drying can result in a further reduction in temperature and thus further protection of the proteins.
- the dried protein preparations are advantageously ground to adjust the functionality, because preparations that have been ground to different degrees show clear differences in the technofunctional properties, such as the emulsifying capacity.
- the grinding is therefore carried out to d90 particle sizes of less than 500 gm, advantageously less than 250 gm, better less than 150 gm, particularly advantageously less than 100 gm.
- a mixture of the preparation according to the invention with protein fractions from legume proteins from the group pea, lentil, bean, broad bean, peanut or soya is advantageous, particularly advantageously only from the group pea and soya, particularly advantageously only soya.
- the reason for soy as an additive to the preparation according to the invention lies in the light color of soy protein isolates, since the particularly light according to the invention Preparation cannot come into its own in a mixture with darker legume proteins.
- a mixture according to the invention should have a protein content of >60%, advantageously >70, particularly advantageously >80% by mass.
- the ratio of the protein according to the invention to the total mass of the mixture should be greater than 5% by mass and less than 95% by mass, advantageously greater than 10% by mass and less than 90% by mass, particularly advantageously greater than 25% by mass. -% and less than 75% by mass, preferably greater than 40% by mass and less than 60% by mass. This makes it particularly possible to combine the functionality of the legume proteins with the good sensory properties and color of the preparation according to the invention.
- the protein content is defined as the content calculated by determining the nitrogen according to Dumas and multiplying it by a factor of 6.25. In the present patent application, the protein content is given in percent by mass, based on the dry substance (TS), ie the anhydrous sample.
- TS dry substance
