Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation, and in particular to a device and method for reusing and treating pickled vegetable water in a tank type fermentation. Background Art

[0002] Sichuan pickled vegetables are vegetable products made from fresh vegetables through salting and lactic acid bacteria fermentation. They taste salty and sour, and are characterized by being crispy, refreshing, and appetizing. During the fermentation process of Sichuan pickled vegetables, it is mainly carried out under the dominance of lactic acid bacteria. However, due to the inevitable attachment of yeasts on the raw materials, such as Pichia membranifaciens and Saccharomyces cerevisiae, the presence of these yeasts has a negative effect, such as causing biochemical changes in pickled vegetables and generating unpleasant sour odors, seriously affecting the quality of pickled vegetables, resulting in deterioration of pickled vegetable quality, a large amount of product waste, and bringing serious economic losses to pickled vegetable production enterprises. Secondly, the pickled vegetable water carefully maintained has excellent flavor, is rich in pectin, dietary fiber, etc., and is nutritious. However, in industrial production, this good pickled vegetable water is generally treated as wastewater. Firstly, the pickled vegetable water contains a large number of microorganisms, and direct discharge will cause pollution to the water environment to a certain extent, and the salt content in the pickled vegetable water is relatively high. Secondly, direct discharge will lead to waste of water resources, etc. Summary of the Invention

[0003] The present invention provides a device and method for reusing and treating pickled vegetable water in a tank type fermentation to solve the above-mentioned deficiencies in the prior art, which can recycle and reuse pickled vegetable water, and reduce environmental pollution and waste of production materials caused by directly discharging pickled vegetable water.

[0004] In order to achieve the purpose of the present invention, the following technologies are proposed:[[]]END]]

[0005] On the one hand, a device for reusing and treating pickled vegetable water in a tank type fermentation is proposed, including a treatment tank. The treatment tank is connected to an ultrasonic sterilizer through a pipeline. After the treatment of high-frequency ultrasonic waves, the microorganisms in it cause the cell membranes of yeasts to perforate and die through the cavitation effect of ultrasonic waves. The ultrasonic sterilizer is connected to an ultraviolet sterilizer through a pipeline, and the ultraviolet sterilizer is connected to a temporary storage tank through a pipeline. The treatment tank is used for filtering and sedimentation operations of pickled vegetable water, the acoustic sterilizer and the ultraviolet sterilizer are used for sterilization of pickled vegetable water, and the storage tank is used for storing pickled vegetable water. This treatment device can filter the vegetables with larger residues in the pickled vegetable water through the treatment tank, and further treat the solid residues in the pickled vegetable water through the method of static sedimentation. By these two filtering methods, the content of solid substances in the pickled vegetable water is reduced, thereby avoiding the impact on the quality of pickled vegetables when reusing pickled vegetable water. The ultrasonic sterilizer and the ultraviolet sterilizer can effectively kill the miscellaneous bacteria in the pickled vegetables, such as yeasts, thus avoiding the impact on the quality of pickled vegetables caused by yeasts during reuse. Through the above device, the adverse effects caused by the discharge of pickled vegetable water are basically solved.

[0006] The treatment tank includes a middle tank body. A plurality of mounting parts are welded on the outer wall of the middle tank body, and support legs are welded on the mounting parts. A liquid outlet pipe is connected to the lower end of the middle tank body. Setting the liquid outlet pipe at the lower end has two advantages. Firstly, it is convenient to completely discharge the supernatant, thereby increasing the recyclable amount of the pickled vegetable water after treatment. Secondly, it can avoid the impurity content in the pickled vegetable water during discharge, thereby improving the quality of the pickled vegetable water during reuse. A transparent plate is provided on the middle tank body, which is convenient for the operator to observe the clarity of the supernatant, so as to reasonably control the timing of discharging the supernatant.

[0007] Considering that when the pickled vegetable water is reused, there are a large number of leaves, rhizomes and other parts of vegetables in the pickled vegetable water that are difficult to take out. These have a common feature that their volumes are large. If conventional filtering components such as common disc-type filtering components on the market are used, these substances are likely to block the filtering components, resulting in a reduction in filtering capacity and efficiency. In addition, it is inconvenient to clean such solids, which further reduces the filtering capacity. Based on existing or common filtering components, in this solution, a filtering tank is installed on the upper end of the middle tank body by bolts. An installation ring is installed on the upper end of the filtering tank by bolts. A conical ring is provided on the inner circumference of the installation ring. The lower end of the conical ring is the small end. A plurality of holes are provided on the conical ring. The lower end of the conical ring is open. The diameter of the upper end of the conical ring is larger than that of the lower end of the conical ring. An upturned edge is formed at the lower end of the conical ring. The cross-section of the upturned edge is in an L-shaped structure. A conical hopper is placed on the upturned edge. The lower end of the conical hopper is the small end. Filtering holes are provided on the conical hopper. A placement ring is provided at the upper end of the conical hopper. The outer circumference of the placement ring is in a conical structure, and the outer circumference of the placement ring abuts against the inner circumference of the conical ring, and the upturned edge passes through the placement ring. A connecting rod is provided at the lower end of the conical hopper. A buckle cover is provided at the upper end of the connecting rod. A downward extension ring is provided on the lower wall of the buckle cover. A connecting convex rod is provided at the upper end of the buckle cover. A pull ring is provided on the connecting convex rod. The conical hopper provided plays a role in filtering. Secondly, during the filtering process, due to the limitation of the structure of the conical ring and the conical hopper, the solids are gathered in the conical hopper and can be removed through the pull ring after gathering for a period of time, so as to achieve the purpose of facilitating the treatment of the filter.

[0008] An end ring is installed on the upper end of the filtering tank by bolts. The end ring is located above the installation ring. The downward extension ring passes through the end ring. The buckle cover is placed on the end ring. An annular part is installed on the end ring by bolts. A liquid inlet pipe is connected to the annular part. A feed hole is provided on the end ring and directly below the annular part. A diversion conical ring is provided on the lower wall of the end ring. The opening size of the lower end of the diversion conical ring is larger than that of its upper end, and the diversion conical ring is located directly below the feed hole. The setting of the buckle cover and the downward extension ring can prevent impurities from entering the filtering tank, and through the provided diversion conical ring, the pickled vegetable water can flow downward from the inner circumference of the conical ring, thereby improving the filtering efficiency and effect.

[0009] Considering that when discharging the supernatant or sediment, it is easy to make the pickled vegetable water in the lower tank turbid. When the supernatant is pumped out, the impurity content in the pickled vegetable water will increase, which will affect the quality of the pickled vegetables. Therefore, a lower tank is installed at the lower end of the middle tank through bolts. A plurality of lugs are welded on the outer periphery of the lower tank. A pair of seal seats are symmetrically arranged on the outer periphery of the lower tank. A rotating shaft is rotatably arranged on the seal seat. A mounting plate is welded between the rotating shafts. The mounting plate is installed with an inner disk through screws. The inner disk is located inside the lower tank. One of the rotating shafts is connected to a servo motor, and the servo motor is installed on the seal seat. A sealing ring is arranged on the outer periphery of the inner disk. A lower convex ring is formed on the lower wall of the inner disk. The outer periphery of the lower convex ring is in a conical structure, and the lower end of the outer periphery of the lower convex ring is the small end. Through the arranged inner disk, when it is in a vertical state, the solid substances in the pickled vegetable water will settle downward. When discharging the pickled vegetable water or sediment, the inner disk is adjusted to a horizontal posture. In this posture, when the supernatant is discharged, the sediment can be prevented from being pumped out due to reasons such as extraction, thus affecting the quality of the pickled vegetable water. By this way of separating backward, the sediment can be prevented from contaminating the supernatant.

[0010] In order to improve the sealing effect of the inner disk, an inner ring is welded on the inner periphery of the lower tank. A plurality of vertical rods are inserted through the inner ring. A limit nut is arranged at the lower end of the vertical rod, and the limit nut is located below the inner ring. A sealing ring is arranged at the upper end of the vertical rod. An inner embedded ring groove is opened on the upper wall of the sealing ring. The outer peripheral side of the inner embedded ring groove is in a conical structure. A sealing rubber ring is arranged on the outer periphery of the sealing ring. The outer periphery of the sealing rubber ring abuts against the inner periphery of the lower tank. A spring is sleeved on the vertical rod, and the spring is located between the sealing ring and the inner ring. When the sealing ring seals the inner disk, the lower convex ring is inserted into the inner embedded ring groove. When the inner disk rotates, due to the pushing action of the inner disk, the sealing ring will rotate downward. When the inner disk is in a horizontal posture, the inner disk and the lower tank can be further sealed through the sealing ring, thus improving the separation and sealing effect.

[0011] Considering the problem that the settled sediment is not convenient to discharge and is easy to contaminate the supernatant during discharge, an inner extending ring is welded on the lower wall of the inner ring. An outer convex edge is formed at the lower end of the outer periphery of the lower tank. A sealing ring groove is opened on the lower wall of the outer convex edge. The outer periphery of the sealing ring groove is in a conical structure. A settling lower tank is arranged at the lower end of the lower tank. The lower end of the settling lower tank is in an arc structure. A pair of rotating shafts are symmetrically arranged on the outer periphery of the settling lower tank. A sealing inner ring is arranged on the inner periphery of the upper end of the settling lower tank. The lower end of the inner extending ring abuts against the upper end of the sealing inner ring. A sealing end ring is formed on the upper end surface of the settling lower tank. A sealing convex ring is formed on the upper wall of the sealing end ring. The sealing convex ring is inserted into the sealing ring groove. Through the above structural design, the sealing effect of the lower tank and the settling lower tank is improved.

[0012] The rotating shaft sleeve is provided with a downward extension arm. At the upper end of the downward extension arm, a rectangular frame is installed. At the four corners of the rectangular frame, downward extension rods are installed. At the lower end of the downward extension rod, a sleeve is sleeved. At the lower end of the sleeve, a moving substrate is installed. At the lower end of the moving substrate, a plurality of universal wheels are installed. The universal wheels facilitate the transfer of sediment. And in order to enable the settling lower tank to perform lifting activities, the downward extension rod and the sleeve are sleeved and connected to each other.

[0013] At the upper end of the sleeve, a pair of connecting cross plates are welded. Waist-shaped holes are formed in the connecting cross plates. A moving rod is inserted through the waist-shaped holes. A moving plate is arranged on the moving rod. At the lower end of the moving plate, a limiting insertion rod is welded. The limiting insertion rod is inserted through the sleeve and the downward extension rod. The connecting cross plate can avoid the problem that the limiting insertion rod is pulled out and lost. And by inserting the limiting insertion rod through the sleeve and the downward extension rod, the limiting insertion rod and the sleeve can be locked.

[0014] In order to avoid the problem of pickled vegetable water spilling due to the swing of the settling lower tank during the transfer of sediment, a pair of strip-shaped holes are formed in the downward extension arm. An adjustable screw is inserted through the strip-shaped holes. At the outer end of the adjustable screw, a nut is arranged. An adjustable plate is arranged on the adjustable screw. The adjustable plate is located outside the downward extension arm. The nut is located outside the adjustable plate. At the lower end of the adjustable plate, a downward pressing cross plate is welded. At both ends of the downward pressing cross plate, upward extension insertion rods are respectively inserted. At the lower end of the upward extension insertion rod, a T-shaped seat is arranged. The lower end of the T-shaped seat is connected to the outer end of the rotating shaft through a pin. During the transfer, only by inserting the upward extension insertion rod into the downward pressing cross plate, the locking purpose can be achieved. This is because the T-shaped seat can only rotate around the rotating shaft. Therefore, when the T-shaped seat rotates, degrees of freedom in the vertical direction and the perpendicular direction are required. However, when the upward extension insertion rod is inserted into the downward pressing cross plate, the movement in the horizontal direction will be limited. And after the movement in this direction is restricted, the rotation of the T-shaped seat will be restricted.

[0015] In order to lock the state of the settling lower tank during the settling process, and in order to improve the sealing effect between the settling lower tank and the lower end of the lower tank body, a rotating connecting plate is hinged to the lug through a hinge shaft. At the other end of the rotating connecting plate, a concave member is welded. At the lower end of the concave member, a downward extension convex plate is welded. At the lower end of the downward extension convex plate, a connecting shaft is arranged. At the outer end of the connecting shaft, an end nut is arranged. A rotating top plate is rotatably arranged on the connecting shaft. The end nut is located outside the rotating top plate. At the lower end of the rotating top plate, a handle rod is arranged. At the upper end of the rotating top plate, an upward top rod is rotatably arranged. At the outer end of the upward top rod, an outer nut is arranged. The outer nut is located outside the rotating top plate. The concave member is sleeved on the rectangular frame. The outer periphery of the upward top rod acts on the lower wall of the rectangular frame, and a concave insertion rod is inserted outside the concave member. The concave insertion rod is located outside the rectangular frame. The concave insertion rod not only plays a role in limiting the concave member, but also plays a role in restricting the rotation of the rotating top plate. And the above-mentioned arrangement of the rotating top plate can make the settling lower tank move upward when it rotates, thereby improving the sealing effect between the settling lower tank and the lower tank body.

[0016] The ultraviolet sterilizer includes a housing, and a plurality of ultraviolet lamps are provided inside the housing. A quartz tube is provided inside the housing, and the quartz tube has a spiral structure. The spiral structure is adopted to extend the killing effect of ultraviolet light on yeasts.

[0017] A stirrer is provided in the storage tank, and a plurality of feeding ports are opened at the upper end thereof. A drain pipe is connected to the lower end of the storage tank.

[0018] On the other hand, a method for reusing the pickled vegetable water in a tank-type fermentation is proposed. A treatment device for reusing the pickled vegetable water in a tank-type fermentation is adopted to treat and reuse the pickled vegetable water in a tank-type fermentation, including the steps of:

[0019] Step 1, pretreatment of the pickled vegetable water: The collected pickled vegetable water is introduced into the filtration tank in the treatment tank to filter out impurities through the filtration tank, and the pickled vegetable water entering the middle tank body, the lower tank body and the sedimentation lower tank is allowed to stand for more than [X] hours.

[0020] Step 2, separation of the pickled vegetable water and the sediment: The servo motor is started to separate the sediment and the supernatant through the inner disc, and continue to sediment for more than [X] hours.

[0021] Step 3, treatment of the pickled vegetable water: The supernatant is pumped out through a peristaltic pump. When pumping out, it passes through an ultrasonic sterilizer and an ultraviolet sterilizer in sequence to sterilize the supernatant through the ultrasonic sterilizer and the ultraviolet sterilizer, and the obtained supernatant is pumped into the storage tank for standby.

[0022] Step 4, treatment of the sediment: After the supernatant is pumped out, the connection between the sedimentation lower tank and the lower tank body is disconnected, and the obtained sediment is transferred to the sediment stacking place.

[0023] Step 5, modulation of the pickled vegetable water: Sterile lye is injected into the storage tank, and the stirrer stirs the pickled vegetable water at a rotation speed of [X] rpm to make the pH value of the pickled vegetable water in the storage tank between [X] and [X].

[0024] Step 6, fermentation of vegetables: The pickled vegetable water in the storage tank is pumped into the vegetable fermentation tank, and when injecting, the pickled vegetable water is prepared according to the volume ratio of pickled vegetable water to water of [X]:[X]. The salinity of the pickled vegetable water for fermentation after preparation is [X]%, and the pickled vegetables and auxiliary materials are sequentially put in and fermented at a temperature of [X] °C.

[0025] The advantages of the above technical solutions are as follows:

[0026] The present invention can realize the reuse of pickled vegetable mother liquor. After the pickled vegetable mother liquor is filtered, precipitated, and the residual impurities are removed, it is then treated by ultrasonic and ultraviolet sterilization to retain the original nutrients and flavor while removing the microorganisms therein, especially the yeast that has a greater impact on the quality of pickled vegetables. Then, after adjusting the pH of the sterilized mother liquor, fermentation is carried out for the second time. This method can not only solve the problems of surface blooming and peculiar smell caused by yeast during the fermentation process of pickled vegetables, but also retain the good flavor substances in the original pickled vegetable water, improving the quality and stability of pickled vegetables.

[0057] The temporary storage tank 4 is provided with an agitator, and a plurality of feeding ports are provided at the upper end thereof, and a drainage pipe is connected to the lower end of the temporary storage tank 4 .

[0058] The tank-type fermented kimchi water recycling and treatment device proposed in this embodiment processes the kimchi water through the following steps:

[0059] Step a: recovering the kimchi water removed from the vegetables, wherein the kimchi water contains a large amount of kimchi residues and solid impurities.

[0060] In step b, the recovered kimchi water enters the annular member 106 through the liquid inlet pipe 107, and flows downward along the upper end of the conical ring 108 through the feed hole and under the guidance of the guide cone ring 111. During the flow, part of the kimchi water will flow downward through the holes into the middle tank body 100 and the components below, and part of the kimchi water will also enter the middle tank body 100 and the components below through the filter holes. The filtered solid matter with a larger volume will be moved into the conical bucket 116 under the flushing action of the kimchi water.

[0061] If the amount of impurities to be filtered is high, the conical bucket 116 is pulled upward using the pull ring 115, and the impurities are then poured into a recovery container. Of course, the kimchi water injection process needs to be paused during this process. Once the solids in the conical bucket are drained, they are placed back onto the conical ring 108.

[0062] In step c, the kimchi water entering the middle tank body 100 and the components below it will undergo sedimentation for at least two hours. During the sedimentation process, it is necessary to ensure that the inner plate 122 is in a vertical position. During the sedimentation process, impurities in the kimchi water will be precipitated into the lower sedimentation tank 137. During the sedimentation process, the operator constantly monitors the turbidity of the supernatant until the turbidity of the supernatant does not change for a period of time.

[0063] In step d, the servo motor 121 is started to make the inner disk 122 in a horizontal position. After the rotation, the spring 133 acts on the sealing ring 127, so that the sealing ring 127 is under the action of the spring 133, and the lower convex ring 125 is passed through the embedded ring groove 128, so that the inner disk 122 seals the lower tank body 118.

[0064] Step e, and sedimentation is carried out again. After the turbidity at the lower end of the supernatant reaches the expected effect, start the peristaltic pump and make the supernatant pass through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3 in sequence through the liquid outlet pipe 170. When the supernatant passes through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3, the yeast in it is basically treated. Among them, the strains contained in Sichuan pickles are disclosed in the papers of the Food Science journal written by the author Liu Chunyan, "Isolation and Identification of Yeast during the Fermentation Process of Traditional Sichuan Pickled Radish and Its Influence on the Flavor of Pickles" and written by Ao Xiaolin, Zhang Xiaoping, Shi Ling, Zhang Xianqin, "Identification of Two Excellent Lactic Acid Bacteria in Pickles and the Influence of Different Fermentation Conditions on the Quality of Fermented Pickles".

[0065] Step f, and the treated pickle supernatant will be stored in the temporary storage tank 4.

[0066] Step g, after the supernatant is discharged, the operator pulls out the concave insertion rod 169 from the outer end of the concave member 161, and then rotates the rotating top plate 165 outward. After that, rotate the concave member 161 inward to cancel the limit of the concave member 161 on the rectangular frame 150. Then, with the cooperation of multiple operators, slowly move the lower tank body 118 to the bottom while pulling out the limit insertion rod 159. Then, separate the liquid from the precipitate by centrifugation, and transfer the separated precipitate to the storage box to be used as raw materials for making feed, etc.

[0067] Step h, after the precipitate is discharged, transfer the sedimentation lower tank 137 to the lower part of the lower tank body 118 again. First, lift the sedimentation lower tank 137, and rotate the concave member 161 outward to limit the rectangular frame 150 through the concave member 161, and rotate the rotating top plate 165 to ensure a sealed connection is formed between the sedimentation lower tank 137 and the lower tank body 118. Then, insert the concave insertion rod 169 on the concave member 161 and wait for the sedimentation treatment operation again.

[0071] Step 02, separation of pickle water and precipitate. Start the servo motor 121 to separate the precipitate from the supernatant through the inner disk 122, and continue to precipitate for more than 2 hours.

[0072] Step 03, treatment of the pickled vegetable brine. The supernatant is pumped out by a peristaltic pump. When pumping out, it passes through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3 in sequence, so as to sterilize the supernatant through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3, and pump the obtained supernatant into the storage tank 4 for standby;

[0073] Step 04, treatment of the sediment. After the supernatant is pumped out, the connection between the sedimentation lower tank 137 and the lower tank body 118 is disconnected, and the obtained sediment is transferred to the sediment stacking place;

[0074] Step 05, preparation of the pickled vegetable brine. Sterile lye is injected into the storage tank 4, and the stirrer stirs the pickled vegetable brine at a speed of 100 rpm, so that the pH value of the pickled vegetable brine in the storage tank 4 is between 6.0 and 6.5;

[0075] Step 06, fermentation of vegetables. The pickled vegetable brine in the storage tank 4 is pumped into the vegetable fermentation tank, and when injecting, the pickled vegetable brine is prepared according to the volume ratio of the pickled vegetable brine to water of 2:1. The pickled vegetable brine contains 90% of the pickled vegetable brine subjected to sterilization operation, and 10% is the unsterilized pickled vegetable brine. The salinity of the pickled vegetable brine used for fermentation after preparation is 3.5%. Then the vegetables to be pickled and auxiliary materials are put in successively, and the vegetables are fermented at a temperature of 25 °C.

[0076] Example 3

[0077] A method for reusing the pickled vegetable brine in tank fermentation, which adopts a device for treating and reusing the pickled vegetable brine in tank fermentation to treat and reuse the pickled vegetable brine in tank fermentation, including the steps:

[0078] Step 01, pretreatment of the pickled vegetable brine. The collected pickled vegetable brine is introduced into the filter tank 104 in the treatment tank 1, so as to filter out impurities through the filter tank 104, and the pickled vegetable brine entering the middle tank body 100, the lower tank body 118 and the sedimentation lower tank 137 is allowed to stand for more than 2 hours;

[0079] Step 02, separation of the pickled vegetable brine and the sediment. The servo motor 121 is started to separate the sediment and the supernatant through the inner disc 122, and continue to sediment for more than 2 hours;

[0080] Step 03, treatment of the pickled vegetable brine. The supernatant is pumped out by a peristaltic pump. When pumping out, it passes through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3 in sequence, so as to sterilize the supernatant through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3, and pump the obtained supernatant into the storage tank 4 for standby;

[0081] Step 04, treatment of the sediment. After the supernatant is pumped out, the connection between the sedimentation lower tank 137 and the lower tank body 118 is disconnected, and the obtained sediment is transferred to the sediment stacking place;

[0082] Step 05, Preparation of pickled vegetable brine: Inject sterile lye into the temporary storage tank 4, and the stirrer stirs the pickled vegetable brine at a speed of 100 rpm to make the pH value of the pickled vegetable brine in the temporary storage tank 4 between 6.0 and 6.5;

[0083] Step 06, Fermentation of vegetables: Pump the pickled vegetable brine in the temporary storage tank 4 into the vegetable fermentation tank, and when injecting, prepare the pickled vegetable brine according to the volume ratio of pickled vegetable brine to water of 2:1. The pickled vegetable brine contains 100% pickled vegetable brine that has undergone sterilization operation. The salinity of the pickled vegetable brine for fermentation after preparation is 3.5%. Then, put the pickled vegetables and auxiliary materials into it in sequence and carry out the fermentation of vegetables at a temperature of 25°C.

[0084] Example 4

[0085] A method for reusing pickled vegetable brine in a tank type fermentation, including the steps:

[0086] Step 01, Fermentation of vegetables: Prepare the fermentation water with clear water and pickled vegetable fermentation agent, and then put the pickled vegetables and auxiliary materials into it in sequence and carry out the fermentation of vegetables at a temperature of 25°C.

[0087] In the above Examples 2 to 4, the vegetables used are radishes, etc., and the auxiliary materials used are seasonings such as peppers and Chinese prickly ashes. And the pickled vegetables and auxiliary materials vary according to specific situations. And such pickled vegetable technology is a conventional technology, so it will not be elaborated here.

[0088] In order to verify whether the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3 can achieve the sterilization effect, the total number of lactic acid bacteria and yeast colonies in the pickled vegetable brine before and after sterilization was measured specifically, and the results are shown in the following table:

[0089] Table 1 Changes in the total number of lactic acid bacteria and yeast colonies in the pickled vegetable brine before and after sterilization

[0090] ,

[0091] It can be seen that through the sterilization operation, the number of lactic acid bacteria and yeast in the pickled vegetable brine can be effectively reduced.

[0092] Table 2 Lactic acid bacteria, yeast, total acid and bag swelling conditions after 2 days of pickled vegetable fermentation under different treatment methods

[0093] ,

[0094] Sensory evaluation results: The pickles prepared in Example 3 had a better flavor, moderate acidity, and a good overall evaluation. Example 1 was the second best. The pickles in Example 4 had a poor flavor and an unpleasant smell. At the same time, the swelling bag experiment showed that the fermentation of yeast in Example 4 produced gas with an unpleasant smell, affecting the overall flavor of the pickles. Although yeast inevitably exists on the surface of vegetables, which is inevitable in pickle making, the overall results show that sterilized pickle water helps reduce the number of yeast in the pickle water, shorten the swelling time, and improve the flavor of the pickles.

[0095] To further verify whether this solution is applicable to various pickles, sterilized pickle water was used as the fermentation water and cowpeas were used as the fermentation object. The results are as follows:

[0096] Table 3 Total acid, yeast, lactic acid bacteria, sensory evaluation, and swelling of cowpeas fermented with sterilized pickle water for 3 days

[0097] ,

[0098] Based on the comprehensive implementation results, this process can shorten the fermentation time compared with traditional fermentation, significantly reduce the number of bad yeast in pickles, extend the swelling time of pickles, and the pickles have moderate acidity, good flavor, and good overall quality. At the same time, this method can also comprehensively utilize the pickle water, reduce environmental pollution, save water, and reduce energy consumption.

[0099] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
