Problems solved by technology

[0003] The traditional meat storage method will cause phenomena such as increased juice loss due to the growth of ice crystals during the storage process, which will lead to the phenomenon that the meat will become stale, taste poor, and lose nutrients after a certain period of storage.

Embodiment Construction

[0022] In order to further understand the invention content, characteristics and effects of the present invention, the following embodiments are enumerated hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0023] See Figure 1 to Figure 3 , a magnetic field-assisted storage method with variable intermittent ratios for meat. The meat is placed in a refrigerated environment with an intermittent magnetic field, and the temperature of the refrigerated environment is controlled within the range of -18°C to -25°C. The ice crystal size of the meat is detected, and the magnetic field opening and closing time ratio is adjusted according to the ice crystal size of the meat. The meat can be cut into appropriate sizes: cubes, square cross-section cuboids; completely frozen meat pieces can be stored in a low-temperature environment, and a certain magnetic field opening and closing time ratio can be preset during the storage process. In the l...

Abstract

The invention discloses a variable intermittent ratio magnetic field assisted storage method for meat. The method comprises the following steps: placing meat blocks in a refrigeration environment with an intermittent magnetic field, controlling the temperature of the refrigeration environment to be in a range of -18 DEG C to -25 DEG C, freezing the meat blocks, regularly detecting the ice crystal size of the meat blocks, and adjusting the opening and closing time ratio of the magnetic field according to the ice crystal size of the meat blocks. The non-thermal effect of the magnetic field on the food is introduced, and the most suitable magnetic field applying process for the corresponding meat is selected through experimental determination, so that the quality of the meat after long-time frozen storage can be obviously improved, juice loss caused by freezing is reduced, and the storage time of the meat is prolonged.

Description

technical field [0001] The invention belongs to the field of food freezing and refrigeration, and more specifically relates to a method for magnetic field-assisted storage of meat with variable intermittent ratio. Background technique [0002] Meat is an important food in people's daily life, rich in protein and amino acids. In order to prolong the shelf life and transportation of meat, the meat is usually frozen and stored at a low temperature of -18°C to -25°C. However, direct low-temperature freezing will lead to a series of serious problems such as serious juice loss after thawing, large drying consumption, and discoloration. Biology itself has a certain degree of magnetism, and under the additional conditions of a magnetic field, it will produce a magnetic field biological effect, which will also affect the freezing process. In addition, the magnetic field has a great influence on water at the microscopic scale, which can break the hydrogen bonds between large water m...
