Definitions
- the present invention relates to a method for treating sugar beets.
- the method includes treating whole or lump sugar beets with an electric field, followed by extraction and / or pressing.
- the process combines gentle processing conditions for sugar beets with a high yield of sugar containing a small amount of by-products.
- Conventional methods of extracting sugar from sugar beets involve a number of mainly physical steps. Since sugar beets have approximately the same density as water, they are moved from the factory stockpiles into water supply canals. These water supply channels contain devices for removing stones, devices for separating waste from vegetation, and devices for washing beets.
- the beets are cut into cossettes, which are long thin strips (ribbons) in the shape of a V or square section. Typically, the ribbons are 2 to 3 mm thick and 15 cm long.
- Sugar which forms between 10 and 22% of all beets, is extracted from the chips in a diffuser. The chips are extracted with water in which the sugar is dissolved. The extraction process is carried out continuously in a counter-current mode. Generally, the extraction is carried out by flowing hot water through the mass of the beet at a temperature of up to 85 ° C. The temperature is chosen so as to extract the maximum amount of sugar without at the same time extracting a large amount of impurities. The strips that are discarded preferably no longer contain a lot of sugar. On the other hand, it is desirable to have as few unsweetened compounds as possible in the extraction water in order to minimize subsequent purification steps.
- the sugar in sugar beet is contained in the parenchymal cells. These cells are mainly made up of a large vacuole containing sucrose surrounded by a cell wall made up of approximately equal amounts of cellulose and protopectin. The walls of the vacuole are covered with protein. When heated, proteins coagulate. Sugar extraction from sugar beet slices is only possible when the cells are permeabilized. Permeabilization is generally carried out by heating the extrusion water to approximately 75 ° C. As other permeabilization processes, the treatment must be mentioned chemical or freezing. One can extract more than a third of the beet juice without heating substantially, that is to say without permeabilization. This is due to the rupture of cell membranes during slicing and to the effect of pressure resulting in further breaking of the cells and releasing fluid during the pressing step.
- CEHP High Pulsation Electric Field
- German patent application No. DE 3,733,927 describes the use of electropermeabilization for the isolation of secondary metabolites from plant cultures.
- the invention described in this German patent application relates to the permeabilization of cell membranes, which are suspended and which are cultivated in a "free" form. Specifically, it is mentioned that the cellular agglomerates are removed from the medium by sieving. Other applications of CEHP have been mentioned.
- An increase in juice yield during the preparation of apple juice and grape juice has been reported by Flaumenbaum (Fl ⁇ ss. Obst 35: 19-20 (1968)). The process is mentioned in this article under the name of electro-plasmolysis.
- Geulen et al. ZFL 45: 24-27 (1994) have undertaken research on pretreatment of carrots by electrical means.
- Russian patent application SU 1521439 describes an electric field treatment applied to sugar beets cut into slices and prepress. Cutting into slices before applying the CEHP results in a sweet juice requiring further purification.
- CEHPs are therefore also used for the sterilization of food intended for humans or animals.
- the advantages of such a process are due to the fact that there is no need to add chemicals, that the permeabilization is carried out at room temperature and that the treatment times are relatively short. Summary of the invention.
- the invention describes a process for the extraction of sugar from whole or lump sugar beets, characterized in that a) sugar beets or large pieces of these sugar beets are treated in water with field pulses electric, b) extracting and / or pressing the sugar beets or pieces of these treated sugar beets.
- the beets are cut or sliced, but the pieces are kept as large as possible.
- the invention specifies the use of CEHP on pieces of sugar beet having at least the following dimensions during the application of an electric field, 2 x 10 x 10 cm (in the form of a block) or 2 x 10 cm (in the form of a cylinder), or similar dimensions in any other form.
- the sugar beets or large parts of these beets are sliced or ground after the CEHP treatment which is prior to the extraction and / or pressing.
- the material treated with CEHP is extracted and / or pressed at a temperature between 0 and 45 ° C.
- the CEHP treatment is carried out using an electric field consisting of strong electric field pulses ranging from 0.5 to 40 kV / cm and from 0.025 to 5 ⁇ F and from 1 to 2000 pulses.
- the CEHP treatment process is carried out during the transport of the beets in the feed channels or after washing and / or cutting the beets.
- Another object of the invention is that the CEHP treatment reduces the number of viable microorganisms which grow on sugar or beet pulp. This has the effect of increasing the possible duration of storage of the product of the CEHP treatment before the sugar is crystallized.
- Another object of the invention is that before or after the CEHP treatment between 0.5 and 40 kV / cm, a treatment is carried out with pulses of the order of 20 to 70 kV / cm in order to inactivate the micro -organisms which otherwise could easily grow on sugar or beets.
- Pressing after extraction is characterized in that the material is treated as follows: a) pressing between 20 and 300 bars, b) resuspending the material in water, and optionally, c) at least one repeating steps a) and b).
- Pressing is also carried out at a pressure requiring the use of a much smaller amount of water. This results in a lower final volume; in such a case, the resuspension in step b) is carried out in water at 1: 0.25 (beet material: water), and the pressing is repeated once at 300 bars for 15 minutes.

- the present invention describes an advantageous process for the extraction of sugar from sugar beets or pieces of these sugar beets.
- the method is characterized in that a) sugar beets or large pieces of these beets are treated in water with electric field pulses, b) the treated sugar beet or pieces of it are extracted and / or pressed beet.
- the extraction is carried out at a temperature below 45 ° C., and preferably the temperature is between 0 and 45 ° C.
- the invention shows the use of CEHP on sugar beet pieces having at least the following dimensions during the application of an electric field, 2 x 10 x 10 cm (in the form of a block) or 2 x 10 cm. (in the form of a cylinder) or similar dimensions in any other form. It should be recognized that the size of the pieces of sugar beet depends on the size of the equipment available for CEHP processing.
- the size of the beets, which can be processed, also depends on the intensity of the field and on the homogeneity of the electric field which can be produced. Cutting and slicing the material results in the release of already large amounts of sugar. However, rupture of the vacuoles and membranes results in a high amount of undesirable impurities in the sugar which is ultimately obtained, and therefore it is preferred to keep the beets or beet pieces as large as possible.
- the electric field is preferably applied in the form of pulses.
- the pulses are at least 0.5 kV and are preferably between 0.5 and 40 kV / cm, the exact value depending on the medium and the type of equipment used. Good results have been obtained with pulses between 1 and 4 kV / cm. It has further been found that the pulses should be applied at a frequency of at least 5 pulses per second or in a total number of 20 to 40 pulses. If low voltages are used, it is also possible to increase the number of pulses to 2000 / seconds or even more.
- Another result of the invention is that the CEHP treatment reduces the number of viable microorganisms which grow in the sugar solution or on the beet pulp. This has the effect of increasing the possible storage time of the product of the CEHP treatment before crystallization of the sugar.
- the invention also aims to administer before or after the CEHP treatment between 0.5 and 40 kV / cm a treatment with pulses of the order of 20 to 70 kV / cm in order to inactivate the microorganisms which otherwise can easily grow on sugar or beets.
- the inactivation of microorganisms and the conditions necessary to do so have been examined by outers, P.C. and J.P.P. ., Smelt in Food Biotechnology 11 (3) 193-229 (1997).
- the CEHP treatment is carried out during the transport of the beets in the supply channels or after washing and / or cutting the beets.
- the capacitance of the capacitor used in the present experiments is between 0.025 and 5.0 ⁇ F.
- the industrial application of the invention requires the adaptation of the capacitor and the pulse generator, and this depends on the type of equipment used and the flow of material that has to be treated.
- Example 1 It is shown in Example 1 that the degree of permeabilization increases with the number and frequency of the pulses, the intensity of the pulses, the capacitance of the capacitor and the conductivity of the immersion medium.
- the temperature and format of the beets or beet slices also play a role. If all these parameters are taken into account, this means that the optimal values of a parameter depend on the fixed value of the other parameters.
- Example 1 It is further shown in Example 1 that the degree of permeabilization obtained with the CEHP treatment (10 kV, 5 ⁇ F, 20 pulses, 1 Hz, 20 ° C) is equal to the degree that is obtained with a heat treatment at 72 ° C. This means that much less energy has to be used and the duration of the process is considerably reduced by applying CEHP treatment.
- the texture measurement shows that the CEHP treatment results in a smoother texture of the sugar beet product.
- the CEHP process can be performed at any desired temperature.
- the temperature is chosen in such a way that the results in terms of yield and purity are high while at the same time the energy requirements are low and the duration of the treatment is also short.
- the CEHP process is carried out at the temperature of the beets and the water which prevails during the sugar extraction campaign.
- the temperature can therefore be between 0 ° C or a near temperature at which the material does not freeze and a temperature in the region of 30 ° C.
- Example 2 shows that the CEHP treatment before slicing results in a slightly lower amount of sucrose in the extraction fluid after continuous extraction. However, a greater quantity of fluid is extracted from the pulp by pressure so that the extractability is equal. Three-stage extraction results in higher extractability of the CEHP-treated pulp and greater juice recovery. When the slices are finely ground, it appears that the material treated with CEHP becomes almost completely extractable.
- Example 6 shows that the difference in extractability between sugar beets treated with CEHP and untreated is much more pronounced when the slices are larger.
- Example 7 confirms this fact for a single pressing. It follows that the CEHP generally results in improving extractability. A smaller number of extraction and pressing steps can be used to obtain the same amount of sugar, or a greater amount of sugar is obtained if the treatment is kept the same. It is found that good results can be obtained when pressing is followed by resuspension and another pressing. This process can be repeated several times, resulting in increased yield and naturally a lower amount of sugar left in the remaining beet pulp. In such a case, the treatment after the electric field pulses is as follows.
- the material treated by electric field pulses is treated as follows: a) pressing between 20 and 50 bars for 5 minutes, b) resuspending the material in water (1: 1 w / w) and c) repeating at least once in steps a) and b).
- the process for treating sugar beets described in the invention results in the extraction from sugar beets of an at least equal amount of sucrose when compared with the conventional extraction process, and it is also shown that under certain conditions the amount of sucrose is higher than that obtained by conventional extraction.
- the process is much faster and requires much less energy.
- the process of the invention requires a duration ranging from less than 1 to 5 seconds and an energy supply of approximately 12 kJ / kg. By increasing the frequency of the pulses, the required energy supply is obtained much more quickly and the duration of the treatment is therefore shortened. With appropriate equipment, it is even possible to reach 2000 pulses / second.
- the treatment temperature is between 0 and 45 ° C, which requires much less energy input than heating to 75 ° C. Note that heating from 25 to 75 ° C requires approximately 20 kJ / kg of water.
- the total amount of water can also be much lower.
- the sugar beet transport water can be used as the medium in which the CEHP treatment is carried out.
- the conductivity of the medium is also important.
- the conductivity of the medium must be lower than that of sugar beet in order to obtain the desired electrical effect. To achieve this, it must be necessary to dilute the water or to add certain salts to the water.
- the purity of the product is higher because the cells have become more permeable without breaking the cellular material.
- the present invention also relates to a method for increasing the rate of dry matter of sugar beet pulp obtained after extraction and / or pressing, characterized in that it comprises a step of treatment of sugar beets or of pieces of these in water with pulses of electric field.
- Strong electric field pulses are generated using an ELSTERIL unit (company Herrfurt, Hamburg, Germany).
- the measurements are taken in Plexiglas cuvettes in which the electrodes are spaced by 2 or 3.8 c.
- the sugar beets are washed with tap water and cut into V-shaped slices having a length of 8 to 12 cm, sides of about 5 mm and a thickness of 12 mm.
- the beets are first cut into blocks (3.8 x 10 x 10-15 cm) or into cylinders and treated with electrical pulses and then cut into slices.
- the standard CEHP treatment is 2 kV / cm, 5.0 ⁇ F, 20 pulses.
- the treatment medium has a conductivity of 0.75 mS / cm.
- the extraction is carried out in an extraction tank containing up to 15 kg of material.
- the temperature is raised to about 75 ° C and the extraction is allowed to take place for about 70 minutes.
- the temperature is 83 ⁇ 2 ° C.
- the temperature is 45 ° C.
- the measurements are carried out on juice which is passed twice through the tank.
- Washed sugar beets are cut into slices and used immediately for extraction, or else blocks of beets are first treated with CEHP and then cut into slices.
- 200 g of slices are mixed with 200 ml of distilled water (85 ° C) and kept at about 85 ° C for 5 minutes after the temperature of the center of the slices has reached 80 ° C.
- the time required to reach a center temperature of 80 ° C depends on the diameter of the slices. In a typical experiment, this time is about 15 minutes.
- the pulp is sieved by hand and the extraction is repeated three times.
- the fluid collected in this first step is used for the extraction of the second stage. The fluid is preheated. After the fourth extraction, the pulp is extracted once again with water.
- the third stage extraction is carried out using the fluid of the second stage, again after the fourth extraction, the pulp is extracted with water.
- the extracts from the third step are used for analytical purposes.
- the pulp extracted from the three stages is pressed at 300 bars and the fluid is stored at -30 ° C before analyzing it.
- the beets treated with CEHP are treated in the same way except for the temperature that is used, the process being carried out at 45 ° C instead of 85 ° C.
- thin slices of sugar beets are used, both untreated and treated by CEHP and the process is carried out. by the same process at 20 ° C.
- 600 g of beet slices not treated or treated with CEHP are mixed with 600 g of hot distilled water at 85 ° C. (untreated), to arrive at an extraction temperature of 75 ° C.
- distilled water is added at 60 ° C, to reach an extraction temperature of 45 ° C, and the extraction is carried out as for the extraction in three stages, but there is n use here as the first step.
- the fluid is used for analytical purposes. The pulp is pressed at 300 bar for 15 minutes, and dried in a fluidized bed dryer at an air speed of 1.5 m / s and at an air temperature of 70 ° C.
- the soluble dry matter (Brix) is measured according to the IFU method No. 8.
- sucrose content is measured by polarimetry. Digestion with hot water: 26 g of slices (untreated) or 60 g of slices (extracted) are mixed with 177 ml of a lead acetate solution (25 ml of lead acetate in 11 ml of water), stirred and extracted while storing at 75-80 ° C for 30 minutes in a covered beaker. After cooling to 20 ° C and filtration, the optical rotational power of the filtrate is determined by polarimetry.
- the texture is measured on cylindrical samples (2 x 1 cm) which are treated in water by maintaining at 20, 45 or 75 ° C for one hour.
- the texture is measured using a penetrometer.
- Ts (%) Dry matter content (g / 100 g) of untreated beet or pressed pulp.
- ° S Sucrose content (g / 100 g) of untreated beet or pressed pulp.
- Weight (%) Weight of pulp after pressing compared with untreated beet.
- WP Weight of pressed pulp (in% of untreated beet)
- ° SP Sucrose content (g / 100 g of pressed pulp)
- Juice purity (%) purity (° S / percentage by weight of dry matter) x 100
- ° S Sucrose content in raw juice (g / 100 g)
- ° Brix dry matter in raw juice (g / 100 g).
- Sugar beet cylinders are prepared (diameter 2 cm and length 10 cm) and placed in the bowl of the electric field generator.
- the degree of permeabilization is measured as a function of the voltage. From FIG. 1, it can be seen that the degree of permeabilization increases slowly between 5 and 10 kV and increases more rapidly between 10 and 15 kV.
- the degree of permeabilization also increases with the number of pulses. From 1 to 5 pulses the increase is very rapid, and above about 20 pulses the effect experiences a plateau. (Figure 2). The degree of permeability is still influenced by the capacitor; with increasing capacity, permeabilization increases ( Figure 3).
- Permeabilization is also influenced by the conductivity of the medium. It is in particular between 0.7 and 1.2 ms / cm that permeabilization must be carried out (Figure 5).
- the degree of permeability depends on the temperature. Up to 55 ° C, no permeability occurs. Above this temperature, the degree of permeabilization increases. From Figure 6, we see that the degree of permeabilization obtained with the CEHP treatment (10 kV, 5 ⁇ F, 20 pulses of 1 Hz, 20 ° C) is equal to the degree that is obtained with a heat treatment at 72 ° C.
- Example 2 As in Example 2, the influence of the slices treated with CEHP on the percentage by weight of dry matter, the purity, the sucrose content (FIG. 10) and the pressability (FIG. 11) are determined.
- Table 2 Three-stage extraction of sugar beet slices.
- the amount of sucrose extracted is only slightly lower with the slices processed by
- the drying of the pressed slices shows that despite the fact that the dry matter content of the CEHP-treated pressed pulp is higher than that of the untreated slices, the characteristics of the drying process are similar. This results in faster drying of the treated slices, and in fact the drying time is shortened by a period of up to 40% (FIG. 14), which results in increasing the energy saving.
- Table 4 One-step extraction of sugar beet slices.
- the slices treated with CEHP (20 or 50 bars for 5 minutes) are lightly pressed three times, intermittently mixing with water (1: 1). During this test, it is observed that the sucrose is collected two to three times faster than with the untreated slices (20 ° C.). In addition, the total quantity of juice is only 40% greater than the quantity of starting slices (Table 5). This underlines the economic advantage of the current process.
- the thermally extracted material is conventionally pressed at 300 bar for 15 minutes, and dried to a much lower dry matter content. This not only means that the process takes longer, but that it is also much more costly from an energy point of view. Table 5. Three presses.
- Figures 16 to 18 and Tables 6 to 8 give an overview of the effect of different sizes of sliced sugar beet materials on extraction and pressing. Pressing is carried out twice (20 bars, 5 minutes and 300 bars, 15 minutes) with intermittent resuspension of the material in a quarter of the volume of water. In general it is found that the CEHP treatment of the sugar beet material results in increased recovery of sucrose compared to an untreated material of the same size. When the size decreases, the effect of the CEHP treatment becomes less pronounced, but the effect is still present and favorable for the CEHP treatment. Table 6. Slices (pressed twice;
- the amount of sucrose extracted for treated beets is greater than it is for untreated material in all cases.
- the figures are 88% against 42%, for thin slices 95.2% against 49% and for crushed material 98% against 89%.
- juices with a high dry matter percentage by weight value and a pulp with a small amount of residual sucrose are obtained. Table 8. Thin slices (pressed twice)
