Problems solved by technology

[0003] However, this food freshness preservation method that slows down life metabolism through low-temperature refrigeration is not a real freshness preservation method. It only provides a quality preservation function for a certain period of time, and cannot inhibit the ripening and decay of food; the real freshness preservation method requires not only Ensure that the food is not spoiled, and keep the food the same as before storage after a period of storage, no matter the taste or nutritional content of the food has not changed

Embodiment Construction

[0018] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0019] This application proposes a food preservation method based on hyperspectral imaging and recognition technology. And the subdivided spectral bands image the target area at the same time, and the obtained hyperspectral image is carefully segmented in the spectral dimension, not only the traditional so-called black, white or R, G, B distinction, but in the spectral dimension There are also N channels on the image, therefore, what is obtained through the hyperspectral sensor is a data cube, which not only has the information of the image, but also expands it in the spectral dimension. As a result, not only the spectral data of each point on the image can be obtained, but also any Influence information for a spectral segment.

[0020] Specifically, such as figure 1 shown, including the following steps:

[0021] St...

Abstract

The invention discloses a food fresh keeping method and a food fresh keeping device. The food fresh keeping method and food fresh keeping device can keep the freshness of food. The method comprises the following steps: obtaining a hyperspectral image of food in a fresh keeping room; analyzing the hyperspectral image to obtain the food information and flora information of the food; based on the food information, controlling a full spectrum illumination module to work according to a set illumination strength; and based on the flora information, controlling a plasma generator to emit plasma rays according to a set emission amount. On one hand, full spectrum illumination can make the food carry out photosynthesis so as the keep the freshness; on the other hand, the plasma generator emits plasma rays according to a set emission amount, plasma reacts with bacteria on the food surface, the bacteria are killed, and the fresh keeping effect is achieved. Based on the change of food information and flora information, the illumination strength and plasma emission amount are adjusted; the full spectrum illumination and plasma quantity are adjusted according to the actual situation, and the fresh keeping effect is realized.

Description

technical field [0001] The invention belongs to the technical field of refrigerator preservation, and in particular relates to a food preservation method and a food preservation device. Background technique [0002] The refrigerator can slow down the life metabolism process of the food stored in it as much as possible by providing a cold storage environment, so as to achieve the effect of maintaining the freshness of the food. [0003] However, this food freshness preservation method that slows down life metabolism through low-temperature refrigeration is not a real freshness preservation method. It only provides a quality preservation function for a certain period of time, and cannot inhibit the ripening and decay of food; the real freshness preservation method requires not only To ensure that the food is not spoiled, it is also necessary to keep the food the same as before storage after a period of storage, regardless of the taste or nutritional content. Contents of the ...
