Description

technical field [0001] The invention relates to a processing method of kiwi fruit of jujube (also known as kiwi fruit), in particular to a method for processing and manufacturing instant kiwi fruit powder of vacuum freeze-drying (FD). Background technique [0002] At present, the kiwi fruit of soft dates is generally eaten fresh, and it is extremely intolerant to storage.

Problems solved by technology

[0002] At present, the kiwi fruit of soft dates is generally eaten fresh, and it is extremely intolerant to storage. It often rots and deteriorates after being stored at room temperature for 5-7 days. Irregular white frozen spots, the color of the fruit itself changes from dark green to light green, more nutrients, especially vitamin C, are lost, the flavor of the fruit changes to a large extent, and the fresh taste of the fruit is lost, etc. The commodity is extremely poor

Moreover, during the freezing process, the area of ​​the freezer of the refrigerator is large, and the power consumption is large, which increases the cost and is not conducive to energy saving and environmental protection.
