Abstract

The invention relates to a method for preserving shredded squid, which belongs to the technical field of food engineering. The method for preserving shredded squid disclosed by the invention comprises: first using a controlled atmosphere preserving machine to package shredded squid controlled atmosphere in mixed gas; and then carrying out low-temperature plasma treatment on the shredded squid packaged in controlled atmosphere. The mixed gas is mixed gas of N2 and CO2, and in the mixed gas, the volume content proportions of N2 and CO2 are respectively 60 to 80 percent and 20 to 40 percent. By integrating controlled atmosphere and low-temperature plasma treatment, the invention improves conventional shredded squid preservation methods, and can effectively sterilize and preserve food without changing the inherent properties of food, prolonging the shelf life of food. The low-temperature plasma treatment of the invention utilizes dielectric barrier discharge generated by a power supply, discharge is uniform, the power consumption of an experimental device is little, the non-toxic and harmless gases are chosen, so that the human being and the environment cannot be harmed, and moreover, the preservation time of food can be effectively prolonged.

Description

technical field [0001] The invention relates to a fresh-keeping method for shredded squid, which belongs to the technical field of food engineering. Background technique [0002] Shredded squid is carefully processed through strict processing technology. It is delicious, moderate in taste and rich in nutrition. It is a favorite snack food for modern people. [0003] Squid has high nutritional value: 1. Squid is rich in calcium, phosphorus and iron, which is good for bone development and hematopoiesis, and can effectively treat anemia. 2. In addition to being rich in protein and amino acids needed by the human body, squid also contains a large amount of taurine, which can inhibit the cholesterol content in the blood, relieve fatigue, restore vision, and improve liver function. 3. The polypeptide and selenium contained in it have anti-virus and anti-ray effects. 4. Modern medicine has found through research that although squid has a high cholesterol content, it also contains...
