Detailed Description
The embodiment of the invention provides a method for preserving fresh Chinese wolfberry by combining acidic oxidation potential water sterilization and vacuum precooling, which comprises the following steps:
step S01, selecting fresh and undamaged fresh jujubes with handles or fresh medlar with handles, putting the jujubes or the fresh medlar with handles into a packaging box with holes of 180 multiplied by 100 multiplied by 50mm, stacking the jujubes and the medlar with handles into soaking baskets, and stacking 20 boxes in each basket to obtain a material storing soaking frame;
step S02, placing weak alkali liquor into an ultrasonic cleaner, placing the storage soaking frame into a tank of the ultrasonic cleaner filled with the weak alkali liquor for soaking, cleaning fresh jujubes or fresh Chinese wolfberries in the storage soaking frame by using ultrasonic waves generated by the ultrasonic cleaner, taking out the storage soaking frame after 150 seconds, draining by using normal-temperature strong wind until water drops do not drop by gravity;
step S03, soaking the drained storage material soaking frame in acidic oxidation potential water, wherein the liquid-material ratio of the acidic oxidation potential water to fresh jujubes or Chinese wolfberries in the storage material soaking frame is 1:5, taking out the storage material soaking frame after soaking for 150S, draining by using normal-temperature strong wind until water drops do not drop under the action of gravity;
and step S04, placing the drained storage material soaking frame into a vacuum precooler for vacuum precooling for 25min, precooling the normal-temperature fresh jujubes in the storage material soaking frame to 10 ℃, precooling the fresh medlar to 4 ℃, and simultaneously evaporating residual water on the surfaces of the fresh jujubes or the fresh medlar to obtain finished products of the fresh jujubes or the fresh medlar.
Step S05, performing modified atmosphere packaging on the fresh jujube finished product or the fresh medlar finished product, wherein the modified atmosphere proportion is as follows: 15% O2+5%CO2。
Further, electrolyzed oxidizing water is generated by electrolyzing sodium chloride, the ORP value of the electrolyzed oxidizing water is 1176 +/-2 mV, the PH value is 2.12 +/-0.3, and the current value is 14A.
Further, the weak alkaline solution generated when the sodium chloride is electrolyzed to generate the acidic oxidation potential water in step S02 has a PH value of 10-12, and the weak alkaline solution can be used to pre-clean oily organic substances, 60% of mold and escherichia coli on the surface of the fresh jujube or fresh medlar, and can also improve the utilization rate of the product of the electrolyzed sodium chloride, thereby achieving the purpose of fully utilizing the product and avoiding waste.
Furthermore, the manner of draining in the steps S02 and S03 is to blow in strong wind from the top of the storage soaking frame, the strong wind enters the inside of the packaging box with holes from the holes of the packaging box with holes to drain the moisture on the surface of the fresh jujubes or the fresh medlar, and the purpose of draining in the steps S02 and S03 is to reduce the moisture on the surface of the fresh jujubes or the fresh medlar and prevent the secondary infection and breeding of bacteria.
In this embodiment, the sterilization steps of the fresh jujubes or the fresh lycium barbarum are steps S02 and S03, the sterilization of the fresh jujubes or the fresh lycium barbarum by using the weak alkaline solution and the acidic oxidation potential water can ensure that the original physical properties of the fresh jujubes or the fresh lycium barbarum, namely the texture, the skin strength, the color, the skin wax layer and the stalk strength of the fresh jujubes or the fresh lycium barbarum, are not damaged in the treatment process, and the sterilization step is the most important step in the preservation step, namely the preservation period of the fresh jujubes or the fresh lycium barbarum is mainly increased by the sterilization method, and in addition, the auxiliary preservation steps are steps S01, S04 and S05.
In step S01, selecting fresh jujubes with stalks or fresh wolfberries with stalks to ensure that the surfaces of the fresh jujubes or the fresh wolfberries are not provided with holes which are easy to infect and breed bacteria, increasing the preservation period by the characteristics of the fresh jujubes or the fresh wolfberries with stalks, subsequently putting the fresh jujubes or the fresh wolfberries with stalks into a perforated packing box with the thickness of 180 × 100 × 50mm, and then stacking the packing box into a soaking basket, so as to relatively fix the fresh jujubes or the fresh wolfberries, avoiding the surface damage and extrusion of the fresh jujubes or the fresh wolfberries caused by repeatedly processing the fresh jujubes or the fresh wolfberries in the subsequent cleaning or soaking process, reducing the dropping rate of the stalks of the fresh jujubes or the fresh wolfberries, and; in the step S04, the temperature of the fresh jujube or the fresh medlar is reduced by using a vacuum pre-cooler, so that the pre-cooling time is shortened for the purpose of quickly cooling and reducing the temperature, the field heat of the fresh jujube or the fresh medlar is effectively and quickly eliminated, and meanwhile, the moisture on the surface of the fresh jujube or the fresh medlar is evaporated to dryness, thereby preventing the breeding of bacteria, and further increasing the fresh-keeping period of the fresh jujube or the fresh medlar after sterilization; in step S05, the purpose of the modified atmosphere packaging of the fresh jujube or wolfberry product is to reduce the probability of the sterilized fresh jujube or wolfberry contacting the outside, and to prevent the secondary infection of bacteria from breeding, thereby increasing the preservation period of the fresh jujube or wolfberry. In this embodiment, the fresh-keeping period is a period of time for keeping the moisture content of fresh jujube or fresh wolfberry fruit above 60%.
The experiments of the invention for sterilizing the fresh jujube or the fresh medlar and determining whether the soaking in the acidic oxidation potential water for 150S in the step S03 meets the sterilization requirement are as follows:
1. test materials:
test groups: 30g of fresh and unbroken fresh jujube with stem or fresh medlar with stem;
comparison group: 30g of fresh and unbroken fresh jujube with stem or fresh medlar with stem;
2. the test method comprises the following steps:
after the test groups are sterilized and preserved by using the method (different soaking times in acidic oxidation potential water in the step S03), fresh medlar is stored in a refrigerator at the temperature of-3 ℃, fresh jujube is stored in a refrigerator at the temperature of 0 ℃, the bacterial quantity of the samples is tested once for the first time, the bacterial quantity is tested once every 5 days, and the average value is obtained by repeating 3 times for each test;
after the comparison group is only soaked in sterile water (the soaking time is different), after the modified atmosphere packaging in the step S05 is carried out, the fresh medlar is stored in a refrigerator at the temperature of-3 ℃, the fresh jujube is stored in a refrigerator at the temperature of 0 ℃, the bacteria number of the initial sample is tested once, the bacteria number is tested once every 5 days, and the average value is obtained after 3 times of testing each time;
3. and (3) test results: (see Table 1)
TABLE 1 soaking time in electrolyzed oxidizing water and non-soaked sterilizing effect
As can be seen from table 1, the sterilization effect of the fresh jujube or wolfberry fruit using the method of the present invention is significantly better than that of fresh jujube or wolfberry fruit only soaked in sterile water, and the number of bacteria detected after soaking in acidic oxidation potential water for 150S in step S03 meets the sterilization requirement, the time is shorter than 300S, the treatment is fast, and the sterilization effect is better than 120S.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
