The small household vacuum packaging machine can effectively reduce food oxidation and maintain the original flavor of food by vacuuming.
1. Choose suitable vacuum packaging materials
Plastic bag type: small household vacuum packaging machine is usually suitable for general plastic bags, composite food bags, aluminum foil bags, etc. In order to ensure good sealing and vacuuming effect, it is recommended to choose plastic bags with moderate thickness and tough texture.
Material characteristics: For food that needs to be stored for a long time, especially ingredients with more water, you can choose plastic bags with good barrier properties, such as aluminum foil composite bags or nylon composite bags, to reduce oxygen permeability and further extend the shelf life of food.
2. Correct operation of vacuum packaging machine
Cleaning and preparation: Before using the vacuum packaging machine, ensure that the machine and plastic bags are clean. Avoid food residues or moisture residue to avoid affecting the sealing effect and vacuuming performance.
Appropriate filling: When putting food into a plastic bag, be careful not to exceed 3/4 of the bag capacity to ensure that there is enough space for vacuuming. At the same time, avoid stacking food too tightly to avoid affecting the vacuum effect.
Adjust the sealing time: According to the size and thickness of the plastic bag, adjust the sealing time of the vacuum packaging machine. Insufficient sealing time may lead to poor sealing, while too long sealing time may damage the plastic bag. Therefore, it is necessary to make flexible adjustments according to the actual situation.
Vacuuming and sealing: After starting the vacuum packaging machine, the machine will automatically perform vacuuming and sealing operations. During the vacuuming process, pay attention to the changes in the pointer of the vacuum gauge to ensure that the required vacuum degree is achieved. After the sealing is completed, check whether the seal is flat and firm.
3. Optimize storage conditions
Low temperature storage: Put the vacuum-packed food in the refrigerator or cold storage for low temperature storage, which can further slow down the oxidation and deterioration of the food. At the same time, low temperature also helps to maintain the original flavor and taste of the food.
Avoid light: Long-term light exposure will accelerate the oxidation process of food. Therefore, when storing vacuum-packed food, try to avoid direct sunlight and strong light.
Regular inspection: Regularly check whether the seal of the vacuum-packed food is intact and whether there is any leakage. If the seal is not tight or there is air leakage, it should be resealed in time.
In summary, by selecting suitable vacuum packaging materials, correctly operating the vacuum packaging machine, optimizing storage conditions and paying attention to relevant matters, the small household vacuum packaging machine can effectively reduce food oxidation and maintain the original flavor of the food.
