Definitions
- the present invention relates to an improved process for recovering oil from plant seeds using enzymes.
- the invention relates to a process in which dry oilseeds are sprayed with enzymes without significantly increasing the moisture content of the oilseed and after which the oilseeds can subsequently be pressed immediately.
- Oilseeds such as soybean, peanut, cottonseed, sunflower seed, corn germ and rape seed (including canola) are the major source of edible vegetable oils. They cover more than 70% of the world's fats and oils production from vegetable raw materials. Soybeans are represented with 20%. These oilseeds are not only the main oil suppliers, but are also very good sources of high-quality protein, which is often used for animal nutrition purposes.
- rape in Germany In addition to its use as edible oil and as a raw material for edible fats, rape in Germany is mainly grown for the production of technical products. Of the Cultivation of winter rape in Germany for the 2004 harvest amounts to approximately 1, 23 million hectares, which corresponds to a rapeseed volume of approximately 3.5 million tons. Well over half of the vegetable oil produced in Germany is now rapeseed oil. Worldwide, the amount of oilseed rape harvested in 2004/5 was 46 million tonnes, with the main production areas of Europe, Canada, USA, Australia, China and India. The cultivation of oilseed rape was the third largest oilseed for soybean and palm oil and is cultivated on approx. 13% of the used arable land. The acreage used for rape cultivation continues to increase worldwide.
- rapeseed oil methyl ester RME
- biodiesel As a waste product hereby glycerol is recovered.
- biodiesel particularly from rapeseed, having as a renewable resource favorable CO 2 balance than fossil fuels, biodegradable and stable than for example Finblumenmethylester (SME) and produced as a diesel fuel during combustion less carbon black, is economically strongly promoted its production worldwide.
- SME Clarblumenmethylester
- the extraction of oil from plant seeds can be carried out by various methods. Usually, the oil is squeezed out of the seed or extracted after comminution of the seeds with organic solvents. Combination processes are also used in which, after a pressing step, the oil fraction remaining in the press cake is extracted with organic solvents.
- the method used depends strongly on the further use of the press cake. In order to be able to serve as feed, no organic solvent must be contained and the remaining oil content should be low, in order to have an optimal energetic value of the protein-rich pressed cake for the interference into the animal feed.
- the extraction method has the disadvantage of high equipment costs and high running costs.
- the solvents eg hexane
- Another disadvantage of the extraction method is that the oil quality achieved is low.
- the oil contains high levels of phospholipids (100-600 ppm P), which must be removed before further processing into either cooking oil or biodiesel.
- the permissible limit values in the edible oil industry are below 10 ppm P, preferably below 5 ppm P, and in the fuel industry below 14 ppm P, calculated in each case as phosphorus.
- the reduction of the phospholipids serves to increase the storage stability, since the phospholipids are hygroscopic and thus attract water, which leads to turbidity in the oil.
- the liberated phosphoric acids are aggressive during combustion and lead to faster wear of the engines.
- Another disadvantage of the extraction method for the application of the extracted oil in the food industry is the high color density of the extraction oil, which must be reduced by adsorption.
- Enzymes have also been used for the digestion of vegetable material to improve the yield of oil from oilseeds (cf., for example, WO 1991/013956 A1 or EP 0 113 165 A1). All such processes are based on the steps of a) crushing the oilseed by milling or pressing, b) adding water and enzyme whereby the moisture content increases to 20% -35% or higher, c) incubating for 6-24 hours at elevated temperature, d ) Pressing or centrifuging off the oil or drying to less than 10% residual moisture and extraction of the oil or a combination of pressing and extraction (cf., for example, Dominguez et al., 1995, Food Chem. 54: 223-231, Dominguez et al. 1994, Food Chem.
- the method should not have the disadvantages of the above prior art.
- a process is to be provided which leads to high yields of oil and to a low phosphatide and moisture content in the oil.
- the method should also be able to use energy and time-saving and should lead to high yields of oil.
- the method should be universally applicable, ie, for example, both for the production of oil for example for the production of biodiesel and for the production of cooking oil are suitable.
- the method should be simple and inexpensive to handle and suitable for a wide variety of oilseeds.
- the invention thus relates to a process for the production of oil from plant seeds, which comprises a) an aqueous, one or more cellulolytic and / or lipolytic and / or pectinolytic and / or proteolytic enzyme (s) and / or phytase-containing Sprayed solution on the seed, b) the seed thus obtained directly in a conventional manner a single or multi-stage pressing optionally in coupling with an extraction, and c) the oil in a conventional manner wins and optionally further processed.
- the invention further relates to the use of this process in the production of edible oil and in the recovery of oil, e.g. for the production of biodiesel.
- the enzyme solution is applied directly to the seed or, in the case of larger oil seeds, to the crushed or ground seed applied without significantly increasing the natural water content of the oilseed.
- the enzyme solution can be sprayed directly onto the dry seed without having to incubate the enzyme-sprayed seed in water.
- the seed can be sprayed as such or after comminution with an enzyme solution.
- an aqueous solution containing the selected enzyme or the selected enzymes sprayed in a conventional manner on the seed.
- the aqueous enzyme solution can be an enzyme solution obtained in a known manner from the culture supernatant of microorganisms (for example consisting of the steps: separation of the biomass from the culture fluid, concentration of the solution obtained by ultrafiltration and sterilization filtration) Stabilizer may contain. But it can also be plant enzymes, such as papain, contained in the enzyme solution.
- the typical amount of enzyme solution applied is on the order of 1000 ppm, based on the weight of the oilseed.
- the water applied by spraying the enzyme solution increases the natural water content of the seeds (4-8% w / w) only by about 0.1 to max. 2% (w / w) based on the weight of the seed.
- the seed prepared in this way can then be fed directly to the compression without further incubation period and without further addition of water, and the oil can thereby be obtained.
- the methods known in the art which use high water contents, for example to prevent product inhibition of the enzymes or to improve the diffusion of the enzymes to the substrates
- the enzymes lead to a change in the cell walls, which improves the outflow of the oil during pressing. For this purpose, no complete degradation of the cell walls by the cellulases, hemicellulases or pectinases is necessary. Proteases help destroy the proteinaceous membrane that surrounds the oil body.
- Phytase helps, especially in phytic acid-rich seeds such as soybean, to reduce the interaction of proteins via phytic acid bridges and thus to improve the oil flow during pressing.
- the low water content also favors the pressing process in that it contributes to the fact that the press cake continues to be pressed in the press. is promoted and it can not build up due to large amounts of water no pressure on the seed and the press cake.
- thermostable enzymes should be used for the process.
- mesophilic and / or thermotolerant enzymes is also possible.
- one or more enzymes are used which are capable of dissolving or at least partially perforating the cell walls or cell membranes of plant cells or loosening the membrane of the oleosins.
- cellulolytic, hemicellulolytic, lipolytic, pectinolytic and / or proteolytic enzymes are used.
- proteases can be used individually or in combination, depending on the structure of the seed, for example, the addition of proteases to protein-rich seed such as soybean is useful.
- the addition of hemi-cellulolytic and pectinolytic enzymes is more useful in seeds, which increasingly contains these storage materials in the cell walls and thus use of cellulases alone would not cause sufficient effect in loosening or perforation of the cell wall.
- pectinases which attack the protoplectin of the middle lamellae, can lead to an improved paste formation for the pressing and thus to an easier oil release.
- galactomannanases may be advantageous, for example with soybeans. Frequently, these enzyme activities are contained in commercially available pectinase products in various proportions.
- the enzyme is selected from natural or recombinantly produced cellulases, endoglucanases, cellobiohydroases, hemicellulases, peptidases, phospholipases, pectinases or phytases.
- variants derived from the above enzymes may also be used, for example, recombinant enzymes prepared on the basis of the above enzymes, which contain parts of the above enzymes and are modified in their activity by addition or removal of substrate binding domains.
- Corresponding enzymes are commercially available or can be prepared by a person skilled in the art. The enzymes can be used singly or in combination. The type and amount of enzyme used depends on the type and amount of seed to be treated.
- the dosages are typically between 100 and 20,000 ppm (w / w), more preferably between 200 and 15,000 ppm (w / w), even more preferably between 500 and 10,000 ppm (w / w).
- the dosage may be higher to account for the loss due to thermal inactivation or low residual activity at the higher temperatures during compression.
- the pressure can be designed in one or more stages. In a multi-stage pressing the addition of the enzymes is also possible between the individual pressing stages.
- the pressing can also be followed by an extraction step, without having to reduce the crushed material (shot) in its water content.
- Methods for carrying out an oil pressing are well known to a person skilled in the art. After pressing, the oil is processed in a conventional manner.
- the inventive method is characterized by an increased throughput of seed per unit time, as well as by an improved press capacity and press yield and a lower phospholipid or phosphatide content in the oil.
- the increased yield and the increased pressing speed also reduce the energy requirement per ton of oil extracted. Since the water content by the application of the enzyme solution to the dry seed increases only slightly, the process comes with the use of extractants without a previous drying and thus has a significantly lower energy consumption in contrast to previously developed enzymatic processes, all the steps for reduction of the water content of> 25% to less than 10% in order not to reduce the yield in the extraction.
- the inventive method has the advantage that the oil obtained is significantly reduced in phosphatide compared to conventional methods and thus, for example in multi-stage pressing process, degumming - ie the reduction of the phosphatide content - can be limited to small proportions of the recovered oil.
- the process according to the invention is very suitable for the production of oil for the production of cooking oil or biodiesel.
- Figure 1 shows the shortening of the pressing time by the use of Melanocarpus cellulase with a Trichoderma reesei CBH 1 cellulase binding domain (representation of 3-fold determinations).
- the process according to the invention can be carried out with any of the abovementioned enzymes.

- One unit of NCU is defined as the equivalent of the release of one nanomole of glucose per second.
- the method is based on the method in Reference Example 1 and uses an incubation temperature of 60 0 C instead of 50 ° C.
- the second deviation concerns the buffer.

- the unit of enzyme activity is CMU g "1 .
- Reference Example 3 Determination of cellobiohydrolase activity
- CBHI Cellobiohydrolase
- EGI endoglucanase
- This reaction can be monitored photometrically by measuring the absorbance of 4-methylumbelliferone under alkaline conditions at 370 nm.
- ⁇ -glucosidase activity in the sample is suppressed by 100 mM glucose in the reaction mixture.
- the proportion of endoglucanase present can be measured individually by addition of 5 mM cellobiose in the reaction mixture, whereby the reaction of cellobihydrolase with 4-methylumbelliferyl-ß-D-lactoside is suppressed.
- ⁇ -glucosidase hydrolyses the substrate 4-nitrophenyl- ⁇ -D-glucopyranoside to 4-nitrophenol and glucose. The reaction is stopped by the addition of alkali and the yellow-colored 4-nitrophenol is detected photometrically.
- One unit of BGU is defined as the equivalent of the release of one nanomole of 4-nitrophenol per second.
- 1, 8 ml of substrate solution (1 mM 4-nitrophenyl- ⁇ -D-glucopyranoside [Merck 6793] in 50 mM citrate buffer [Merck 6448], pH 4.8) are heated at 50 0 C for 5 min. Thereafter, 200 .mu.l of diluted enzyme solution are added and incubated at 50.degree. C. for 10 min. After 10 minutes, 1 ml of 1 M Na 2 CO 3 solution is added and the absorbance at 400 nm is measured against an identically treated reaction blank with water instead of enzyme solution.
- the calibration curve is set up with 4-nitrophenol [Sigma 104-8].
- the phosphatide content (also called phospholipid content) is expressed in ppm of phosphorus in the oil. It is determined by ashing at 85O 0 C with the addition of magnesium oxide as phosphomolybdate photometrically at 830 nm. For calibration K 2 HPO 4 is used.
- the phosphatide content can also be determined by flame photometry using an AAS device directly in the oil.
- the phosphatide content in the total oil of the rapeseed of Examples 1 to 3 extracted by the method according to Reference Example 6 with n-hexane was about 93 ppm P.
- the rapeseed of Examples 1 to 3 contains 41% oil.
- the oil obtained by pressing or by extraction from an oilseed is centrifuged at 12,000 x g for 5 minutes to separate suspended particles, and then the color is determined in a 1 cm cuvette at 508 nm against water in the photometer.
- Example 1 Use of enzymes to increase the pressing speed
- the press ran at a speed of 25 rpm and was equipped with a press head equipped with 12 mm opening and adjusted to a gap of 1, 5 mm.
- the residence time of the rapeseed in the pressing head was about 1-2 minutes.
- the press head was fitted with a thermosensor with a connected Roth measuring device to determine the temperature of the presshead.
- the oil was collected in a glass bowl standing on a balance and the amount and the pressing speed and the temperature of the oil determined.
- the press cake was placed in another shell standing on a separate balance and was then comminuted in a coffee grinder with impact mechanism for the determination of the residual oil content by extraction according to Reference Example 6.
- the content of phosphatides in the extracted oil was very low at 6.5-8 ppm P, allowing direct further processing of the oil in the food industry and also for the production of biodiesel.
- the values of the phosphatide content were 5% - 10% lower than those without enzyme addition. This was to be expected with the absolutely low Phosphatidiere.
- the pressing head temperature without enzyme addition was in average over all three measure- ments at 77.0 0 C, whereas when using the endoglucanase, despite increased
- the color of the pressed oil improved with enzyme addition from an average absorption of 0.801 AU to 0.776 AU. These values are significantly better than the color of the oil extracted from the rapeseed with only hexane of 1.2 AU and thus make it possible to reduce the use of bleaching agent / bleaching earth during processing to edible oil and to save costs.
- thermoascus aurantiacus cellobiohydrolase carrying the T ⁇ choderma reesei CBH 1 cellulosic binding domain at the C-terminal end (for example prepared according to WO 2006/117432 A1) was used at a dosage of 180 PCU per kg rapeseed in the same experimental set-up.
- the cellobiohydrolase has a molecular weight of about 46.2 kDa and the attached CBH1 linker and the CBH1 binding domain of about 6.8 kDa.
- the enzyme shows a temperature optimum of about 65 ° C.
- an increase in the throughput and thus a 10.8% higher amount of oil per unit time could be achieved hereby.
- Example 2 Mesophilere enzymes than that in the tests 1 and 2, and Example 2 th verwende- as the endoglucanase I from Trichoderma reesei (described for example in EP 0137280 A1) with a temperature optimum of about 50 0 C, higher dosages could in also contribute to a shortening of the relative pressing time and thus to an increase in throughput.
- a dosage of 376,000 BU per kg rapeseed an increase of throughput by 2,1% and at a dosage of 752,000 BU per kg of rapeseed an increase of throughput by 6,3% could be achieved.
- Example 2 Use of Enzyme Mixtures to Increase the Pressing Speed and Improve the Yield of Pressed Oil
- Example 1 An enzyme other than that used in Example 1 was used for the experiments, namely a neutral cellulase of Melanocarpus albomyces produced recombinantly with Trichoderma reesei and containing a Trichoderma reesei CBH1 cellulose binding domain, as described in WO 2006/117432 A1, and the endoglucanase produced by recombinant with Trichoderma reesei from Acremonium from Example 1, Experiment 1.
- the Melanoca ⁇ us cellulase has a molecular weight of about 20.2 kDa and the attached linker with the CBD of cellobiohydrolase 1 from Trichoderma reesei has a molecular weight of about 6 , 8 kDa.
- the enzyme has a temperature optimum of about 75 ° C.
- the dosages were 64,400 CMC per kg rapeseed for Acremonium endoglucanase and 130,000 NCU per kg rapeseed for neutral melanocytic cellulase.
- the sprayed amounts of the enzyme solutions were each 0.1% (w / w) based on the mass of rapeseed.
- the enzyme solutions were sterile filtered ultrafiltrates with a dry matter content of about 15% (w / w).
- the experimental setup was as in Example 1 except that the nozzle opening was only 10 mm instead of 12 mm. This allows better press results to be achieved.
- the same oilseed rape (same batch) as used in Example 1 was also used, so that the results are directly comparable. The results are shown in Table 1.
- Table 1 Use of a cellulase or an endoglucanase to improve the yield of oil in the press of oilseed rape and reducing the pressing time to obtain the same amount of oil.
- the water approach used the same amount of water (0.1% w / w based on the weight of rapeseed) as applied to the enzyme solutions.
- the relative pressing time is the time needed to get the same mass of oil.
- the oil yield indicates the absolute yield of oil from the rapeseed, regardless of the duration of the pressing process.
- the yield of oil can be increased during the pressing with the aid of appropriate enzymes.
- the advantage of this oil is the low phosphatide content, which allows direct further processing without desliming. This is also true, in spite of about 10 0 C higher lying pressing head temperature as compared to the conditions in Experimental Example 1. This temperature increase is caused by the narrowing of the gap opening of the press and the thus caused higher pressing pressure.
- the phosphatide content in the pressed oil increased as expected from 8 to 14 ppm P compared to the conditions with a larger nozzle (Example 4) and is thus above the limit for edible oil and at Limit on the content permitted for biodiesel production.
- the phosphatide levels in the enzyme-supplemented oil as well as in Example 4 were at a lower level of only 8-9 ppm P.
- the addition of enzyme has therefore also a positive effect on the lowering of the phosphatide contents in the pressed oil compared to oil, which was obtained without enzyme addition, impacted. This allows the further processing of the oil thus obtained directly without degumming to cooking oil, as well as to biodiesel.
- Table 2 Determination of the phosphatide content of the residual oil extracted from the presscake.
- the use of enzymes greatly inhibits the liberation of the remaining phosphatides upon extraction of the residual oil still remaining in the press cake (total oil minus press oil, about 16-17% of the total oil).
- total oil minus press oil about 16-17% of the total oil.
- total amount of oil * phosphatide content of the oil obtained by extraction The press oil contains only 0.274 to 0.309 mg P (press oil * phosphatide content in the press oil) and the subsequently extracted residual oil again 0.474 to 0.492 mg P (residual oil * phosphatide content in the residual oil).
