Abstract

The invention discloses a freezing and fresh-keeping method for meat products, which comprises the steps of selecting meat products, freezing meat products, adjusting the temperature and the humidity of a cold reservoir, venting the cold reservoir, and the like. According to the invention, after meat products are selected and cleaned, meat products are rapidly precooled. Therefore, the quick-frozen load of the cold reservoir is reduced and the fresh-keeping effect of meat products is improved. Meanwhile, the energy is saved at the same time. Meanwhile, through the cooperation of an additionally added anti-staling agent and the ventilation process, the quality of meat products is effectively prevented from getting deteriorated or worse during the storage process. Therefore, meat products can be stored for a sufficient period of time.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping meat products, in particular to a freezing and fresh-keeping method for meat products. Background technique [0002] With the development of the market economy, during the production, transportation, sale or storage of poultry meat, livestock meat and other meat products, it is often necessary to freeze fresh meat in cold storage to provide a guarantee for the freshness of meat products. When using cold storage to keep fresh meat products, improper or inappropriate operation will affect the fresh-keeping effect of meat products, so that meat products cannot be stored for a long enough time, deteriorate or decline in quality during storage, and affect later sales and income. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a method for freezing and fresh-keeping meat products with good freezi...
