Problems solved by technology

However, the fresh-keeping technology of red bayberry is a comprehensive technology closely combined with picking, pre-cooling treatment, packaging protection, packaging material performance and refrigeration temperature. It is difficult to achieve the ideal fresh-keeping effect only with a single condition.
However, the traditional quick-freezing method utilizes a quick-freezing machine to instantly cool down the red bayberry and then freeze it. The investment is small, but the storage time is short (usually about 20 days), the taste and meat quality will change significantly, and even mildew
At present, artificial controlled atmosphere (CA) packaging is the most effective method for bayberry, but its best shelf life is only 24 days. Therefore, the picking of bayberry, pre-cooling conditions, packaging protection, packaging material parameters, and cold storage Only by optimizing the ratio of conditions can the best fresh-keeping effect be achieved

Embodiment 1

[0024] After the red bayberry is picked (it can be picked when it is half mature), it is placed in a plastic or rattan turnover box (requires good air permeability), 5Kg per box, and placed in a 1-4°C refrigerator (with a certain dehumidification function to achieve cold storage). In a dry environment, the dry environment is conducive to the preservation of bayberry), the pre-cooling of circulating dry cold air is used for 7 to 12 hours, and the cold room is equipped with an air circulation system to form circulating dry cold air, and the air circulation is conducive to the pre-cooling of bayberry. After pre-cooling, the bayberries are quickly uniformed and fixed (when fixing, a bracket can be set in the fresh-keeping box. In addition to fixing the bracket, the bracket can also prevent the bayberry from colliding with each other and contacting the bottom surface of the box, and at the same time increase the amount of air between the bayberry and the box. The contact area, t...

Embodiment 2

[0026] After the bayberry is picked (it can be picked when it is half mature), it is placed in a plastic or rattan turnover box (requires good air permeability), 10Kg per box, and placed in a 1-4°C refrigerator (with a certain dehumidification function to achieve cold storage). In a dry environment, the dry environment is conducive to the preservation of red bayberry), the pre-cooling of circulating dry cold air for 9 hours, and the cold room is equipped with an air circulation system to form circulating dry cold air, and the air circulation is conducive to the pre-cooling of bayberry. After pre-cooling, the bayberries are quickly uniformed and fixed (when fixing, a bracket can be set in the fresh-keeping box. In addition to fixing the bracket, the bracket can also prevent the bayberry from colliding with each other and contacting the bottom surface of the box, and at the same time increase the amount of air between the bayberry and the box. The contact area, the bracket materi...

Abstract

The invention relates to a comprehensive method for refrigerating and refreshing waxberries. The method comprises the following steps: (a) precooling treatment: picking up the waxberries, and putting the waxberries in a refrigerating chamber under the temperature of 1 to 4 DEG C for precooling for 7 to 10 hours; (b) modified atmosphere packaging: putting the waxberries after the precooling treatment in a refreshing container, charging mixed gas, and enclosing the container with sealing films; (c) refrigeration: putting the waxberries which are packaged well in the refrigerating chamber for storage. A comprehensive technology is adopted for refreshing the waxberries, and the optimized ratio combination of technical parameters, such as precooling temperature and time, the arrangement and the spacing ratio of the waxberries in the refreshing boxes, the ratio of the mixed gas, the performance requirements of the sealing films of the refreshing boxes, refrigerating temperature, enables fresh waxberries to be stored for 4 months, the perfectness ratio of the waxberries reaches more than 98%, the problem that the waxberries cannot be stored for a long time is solved, and the taste, the color and the quality of the stored waxberries do not change obviously.

Description

[0001] technical field [0002] The invention relates to a comprehensive cold storage and preservation method for red bayberry. Background technique [0003] Red bayberry (Myrica rubra) is a specialty fruit in southern my country. The fruit is sweet and sour, juicy and full-bodied. Due to the physiological characteristics of red bayberry itself, it is a fruit with strong respiration. In addition, the ripening season of red bayberry coincides with the intense heat, and there is no exocarp. In addition, the collection is concentrated, the time is short, and the red bayberry is very easy to mold, rot and deteriorate. Protection, storage and Transportation is extremely difficult, and post-harvest loss is serious, and there is a saying that "the taste changes in one day, the color changes in the next day, and the quality changes in three days". Safe and efficient fresh-keeping storage and transportation technology has become a key factor to promote the industrialization of baybe...
