With the continuous improvement of people's requirements for food safety and quality, the storage and preservation of meat products has become an important issue. As an effective storage method, ultra-low temperature cold storage is widely used in the storage and preservation of meat products. However, there are some things that need to be paid attention to during the ultra-low temperature cold storage of meat products to ensure the quality and safety of meat products.
1. Choose the right temperature.
The temperature of ultra-low temperature cold storage needs to be selected according to the type and demand of meat products. In general, for meat products that need to be stored for a long time, a lower temperature such as -18 or lower can be chosen. For meat products that need to be stored for a short period of time, you can choose a slightly higher temperature, such as minus 12 or minus 15. At the same time, it is necessary to ensure that the temperature of the cold storage is stable and avoid the impact of temperature fluctuations on meat products.
2. Maintain proper humidity.
Humidity control is also very important in ultra-low temperature cold storage. If the humidity is too high, it is easy to cause mold in meat products;If the humidity is too low, it is easy to cause water loss in meat products. Therefore, it is necessary to maintain appropriate humidity according to the type and demand of meat products. In general, meat products with a high moisture content, such as meat, need to maintain a high humidity;For meat products with a low moisture content, such as dried meat, a low humidity can be maintained.
3. Avoid cross-contamination.
In ultra-low temperature cold storage, it is necessary to avoid cross-contamination of different types of meat products. Different kinds of meat products may carry different microorganisms and bacteria, which can easily lead to food safety problems if cross-contamination. Therefore, different areas need to be divided in the cold storage for storing different meat products. At the same time, the cold storage needs to be cleaned and disinfected regularly to ensure the hygiene and safety of the cold storage.
Fourth, pay attention to packaging and labeling.
Meat products stored in ultra-low temperature cold storage require the use of suitable packaging materials and labelling. The packaging material needs to have a good seal and low temperature resistance to ensure that the meat products will not get damp or moldy at low temperatures. At the same time, it is necessary to clearly mark the product name, production date, shelf life and other information on the packaging to facilitate management and sales.
5. Regular inspection and maintenance.
Ultra-low temperature cold storage needs to be inspected and maintained regularly to ensure its proper operation and safe use. It is necessary to regularly check whether the temperature, humidity, power supply and other equipment of the cold storage are working properly;At the same time, the cold storage needs to be cleaned and disinfected regularly to avoid bacterial growth and contamination. In addition, it is also necessary to regularly maintain and maintain the equipment of the cold storage to ensure its normal operation and service life.
In short, the storage of meat products in ultra-low temperature cold storage needs to pay attention to temperature, humidity, avoid cross-contamination, pay attention to packaging and labeling, and regular inspection and maintenance. Only by strictly following these precautions can the quality and safety of meat products be ensured. Cold storage
