Definitions
- the invention relates to a process for the production of cloudy, cloudy juice from vegetable products for the production of beverages by adding filter residue, in particular retentate from a cross-flow filtration of raw juice obtained from vegetable products.
- Fruits, berries, grapes, citrus fruits and vegetables are particularly considered as vegetable raw materials for obtaining these juices.
- the cold-sterile production of cloudy fruit juice in particular orange juice
- the cold sterilization takes place by means of ultrafiltration and a possible concentration by means of reverse osmosis.
- the retentate (pulp) from the ultrafiltration is pasteurized, for example, and becomes the permeate from the ultrafiltration, or. added to the concentrate from the reverse osmosis.
- a disadvantage of these known methods is that the retentate added to the clear juice for clouding sediments out relatively quickly. Sedimentation is even observed if the original juice was sufficiently turbid before membrane filtration. This problem is particularly critical when using the known methods for fruit juices, since such juices, unlike citrus fruit juices, are practically not accepted by the market. The reason for this is that naturally cloudy fruit juices are largely stable to turbidity and the consumer has got used to these juices. In contrast, shaking citrus fruit before use is not offensive.
- the object of the invention is therefore to increase the turbidity stability of the cloudy juice and to prevent the clouding agents added to the juice from being sedimented.
- this object is achieved in that the filter residue is subjected to at least one size reduction and is mixed with at least one stabilizing agent.
- FIG. 1 shows a diagram of the method according to the invention for producing cloudy, cloudy juices from clear juice and Fig. 2 shows another embodiment of the method for producing cloudy stable, practically cold sterile, cloudy juices.
- the raw juice obtained from fruit, berries, grapes, citrus fruits or vegetables is fed via a line 1 to an ultrafiltration system 2.
- Cold sterilization of the raw juice takes place in the ultrafiltration system 2.
- Other cross-flow membrane processes can also be used for this purpose, but preferably ultra or microfiltration with downstream safety microfiltration (filter candles).
- filter candles downstream safety microfiltration
- the permeate of the ultrafiltration system 2 is fed as cold sterile clear juice via a line 3 into a mixing device 4.
- the mixing device 4 which can consist, for example, of a static mixer, filter residues, preferably the retentate, of the ultrafiltration system 2 are fed to the clear juice via a line 5 in order to obtain the desired cloudiness of the clear juice. Filter residues from other filtration systems can also be used.
- Filter residues from other filtration systems can also be used.
- the filter residue arrives in the mixing device 4, it is finely comminuted in a comminution device 6.
- FeineZer comminution is understood to mean a comminution in the particle size, as is achieved by means of known methods for wet grinding.
- the comminution device 6 it is preferably mainly finely comminuted to a particle size ⁇ 75 ⁇ m.
- the degree of comminution required largely depends on the structure and density of the particles.
- Wet comminution methods such as those used for refinement and. Are preferably used as the means for the finest comminution Homogenization of dispersions and the production of emulsions can be used.
- colloid mills homogenizers such as high-pressure homogenizers or microfluidizers can be used.
- the comminution can also be supported by a previous enzyme treatment, for example by means of cellulase enzymes.
- stabilizing agents are also introduced into the mixing device 4 via a line 7.
- the task of the stabilizing agents is to prevent agglomeration of the finely ground particles.
- the sediment particles sediment out again after a relatively short time. The same would happen if, in addition to the opacifying agents, only stabilizers were added to the juice without very fine grinding.
- the stabilizers used are preferably those agents which occur in plant products, in particular in the vegetable raw materials used. An example of this is the use of pectin as a stabilizing agent.
- 8 fibril substances can be introduced into the mixing device 4 for the production of cloudy juices with fibril substances via a line. After the mixing process in the mixing device 4, a cloudy, cloudy juice is discharged as a result via the line 9.
- the order of the above steps can also be selected differently depending on the situation.
- the very fine comminution is already possible in the ultrafiltration system, for example by installing appropriate devices in the circulating circuit and, for example, performing the very fine comminution at the end of the filtration.
- a further possible application of the method according to the invention is the clouding of rediluted clear juice concentrates.
- clear juice concentrate is introduced as the starting material from a concentrate store 10 via a line 11 into the mixing device 4. Water is added to the clear juice concentrate via a line 12 (FIG. 1).
- a "Trottenmost" -like cloudy juice can be produced.
- the juice is preferably cold deodorized before concentrating or even before clarification, for example by means of membrane processes such as pervaporation or reverse osmosis, and the aroma is likewise enriched by means of a membrane process and then stored separately from the concentrate.
- This application is used, among other things, for the uniform production and storage of clear juice concentrates during the harvesting campaign and for clouding the juices as required during storage. This avoids bad planning due to incorrect market forecasts. This procedure can be particularly worthwhile if predominantly clear juices are required for sales and the juices are clarified by means of a continuous or semi-continuous process, e.g. by means of ultrafiltration.
- Another application is the production of juices with different turbidity levels based on a certain sugar content. This makes it possible to bring cloudy juices to the market in a simple manner with different levels of cloudy content. This also applies to the production of cold sterile, cloudy juices and the clouding of back-diluted clear juice concentrate and for other cases.
- dietary agents can also be produced with an increased proportion of non-indulgent fiber.
- curries are suitable e.g. also as food additives e.g. to yog hurts.
- cloudy juice can also be used as the starting material for the process according to the invention.
- the reason for this is the production of pulpy juice or Purr ⁇ e from juice with a relatively low turbidity, e.g. Fruit juice.
- turbidity stability of the starting juice it is appropriate here to subject the starting juice to a very fine comminution. In certain cases, this is possible together with the opacifying agent, which is additionally added.
- the opacifier to be added is preferably used in liquid dispersed form. This shape is particularly well suited for fine grinding. Further treatment steps are also possible in a simple manner.
- dry products can also be used as an alternative to the liquid form of the opacifying agent.
- Fig. 2 an embodiment for the production of cloudy stable, practically cold sterile, cloudy juice is shown.
- the retentate from the previous ultrafiltration system 2 or another crossflow filtration system can be used as an opacifier.
- the retentate is introduced into a buffer 14 via a line 13 and pretreated in a pretreatment stage 15 as required. This happens for example wise by cleaning undesirable substances, such as flavors, possibly alcohol, etc., by bleaching, concentrating or sterilizing. Appropriate cleaning is particularly important if the juice and retentate do not come from the same herbal product.
- the sequence of the individual treatments is open and must be adapted to the given situation.
- Bleaching in particular of retentate from membrane filtration, is generally relatively difficult, since they are polymeric oxidation products. For these reasons, relatively high concentrations of bleaching agents or. particularly strong bleaching agents are used which have to be removed again practically completely or converted into harmless compounds.
- the bleaching agent is preferably added before and / or with the very fine comminution, which in this case is preferred in the course of the process.
- the bleaching agents or conversion products thereof are preferably washed by means of membrane filtration by diafiltration.
- Membrane crossflow processes are particularly suitable as processes for cleaning, bleaching or concentration, e.g. Diafiltration with cleaning water for cleaning the retentate, possibly combined with a concentration of the dispersion.
- diafiltration with e.g. Sulfurized water is used as a bleaching agent and relatively large-pored membranes for high flux are used for concentration.
- the retentate which has been cleaned and bleached in the pretreatment stage 15, is then introduced into the very fine comminution device 6.
- the retentate of the ultrafiltration system 2 can also be fed into the ultrafine comminution device 6 are initiated.
- the dispersion is stabilized by supplying stabilizing agent via a line 17 in order to prevent agglomeration.
- fibrile substances are added to the dispersion via a further line 18.
- the additives in particular opacifiers and stabilizers, reach the mixing device 4, they are combined in a line 19 and fed to a sterilization device 20 upstream of the mixing device 4 and sterilized there.
- Sterilization is e.g. possible for each component individually or together for all components in the sterilizing device 20.
- the sterilization can be carried out, for example, with heat, predominantly by pasteurization. The heat influence is low, since the dispersion is taste and aroma neutral and represents a relatively small amount.
- the sterilization can be carried out for a qualitative improvement by a completely cold production, e.g. with electroshock treatment, ultrasound treatment methods, UV radiation, silver ion treatment, high pressure treatment, etc. Although these methods are relatively expensive, the amount is relatively small due to the concentration of the opacifiers. For safety reasons, a combination of cold sterilization methods is preferable.
- the fibril materials are preferably dispersed in a liquid, for example water, juice or cold-sterile juice, before sterilization.
- the sterilization can be carried out in isolation or together with the other additives in the sterilization device 20.
- the requirement for turbidity stability can normally be dispensed with for the fibril material. Nevertheless, it is desirable that the remaining turbidity components do not sediment out.
- the raw juice or rediluted, cloudy concentrate is introduced into the cold-run ultrafiltration system 2 and introduced as cold-sterile clear juice via line 3 into the mixing device 4 and there with the sterilized Additives mixed.
- the juice mixed in this way leaves the mixing device 4 via line 9 as a practically cold-sterile, cloudy stable, cloudy juice.
- the cold sterilization methods can also be carried out in a cold safety sterilization 21 arranged downstream of the mixing device 4.
- back-diluted clear juice concentrate can also be used as the starting material.
- the clear juice concentrate is fed via a line 22 to at least one sterile microfiltration system 23, which is designed as a safety filter, and is introduced directly into the mixing device 4 via a line 24.
- the retentate of the cross-flow filtration system used in the process according to the invention for turbidity is a fairly complex, non-fibrile product which does not only contain cellulose.
- the retentate also contains valuable protein substances.
