Description
Technical Field
The invention relates to the field of gel water ball manufacturing and processing, in particular to a device and a method for manufacturing an ozone-rich gel water ball and the gel water ball.
Background
The fruit and vegetable has strong resistance before being harvested, and is not easy to be infected by microorganisms, but the resistance of the fruit and vegetable to the microorganisms is reduced along with the progress of life activities after being harvested, so that the fruit and vegetable is easy to be infected by the microorganisms, and the fruit and vegetable is rotten to lose commodity value.
At present, the storage mode of fruit and vegetable fresh-keeping is mainly based on common low-temperature and chemical preservative modes. However, these methods are mainly chemical means, and there is a possibility that the fruits and vegetables are subjected to secondary pollution. Therefore, the development of cheaper, efficient and safe fruit and vegetable storage and preservation technical means for controlling the after-ripening and aging of the fruits and vegetables and ensuring the edible safety of the fruits and vegetables is urgently needed.
In recent years, ozone fruit and vegetable fresh-keeping is fast in sterilization and free of secondary pollution, and is gradually a research hotspot in the field. By utilizing the strong oxidation and sterilization characteristics of ozone, ethylene in the storage environment of fruits and vegetables can be rapidly decomposed, and microorganisms in the storage environment can be killed, so that the aim of prolonging the fresh-keeping period of the fruits and vegetables can be fulfilled. In addition, harmful gases such as ethylene, ethanol, acetaldehyde and the like released by respiration of fruits and vegetables can be eliminated by ozone treatment, so that the respiration effect of the fruits is reduced, and the aging of the fruits and the vegetables is delayed.
Although the ozone is rapidly developed in the food industry, the ozone is still in the beginning stage in the aspect of fruit and vegetable preservation. The reason is that: (1) the sterilization effect of ozone is greatly influenced by temperature and humidity, different fruits and vegetables have different requirements, and the use of ozone is limited; (2) when the fruits and vegetables are in a sealed package state, the effect of keeping fresh by using ozone in a refrigeration house is not ideal; (3) the complete equipment of the ozone generator is developed slowly, so that the ozone is not widely applied to the fruit and vegetable fresh-keeping industry; (4) the high-concentration ozone has the harm effect on eyes, skin and respiratory tract of people, and meanwhile, the high-concentration ozone can reduce the quality of fruits and vegetables.
In addition, related researches also indicate that firstly, the relative conductivity of cell membranes of fruits and vegetables is improved by higher-concentration ozone, and chlorophyll and carotenoid are easy to damage; secondly, when the fruits and vegetables are preserved, if the ozone is used in improper concentration, the cells of the fruits and vegetables can be damaged, so that the permeability of the fruits and vegetables is increased, and the cell contents are leaked, thereby causing the quality reduction or the deterioration. On the contrary, other studies show that low-concentration ozone has good sterilization and fresh-keeping effects even under the conditions of low temperature and high humidity for a long time. For example, the ethylene generated in the storage process of fruits and vegetables can be effectively degraded, and meanwhile, the ethylene-containing composite material has a good inhibition effect on microorganisms causing food spoilage, such as mold and the like.
Therefore, an effective ozone preservation packaging method needs to be developed, so that the concentration of ozone in a closed environment can be maintained in a lower concentration range for a longer time, and the fruit and vegetable protection is facilitated.
