Abstract

The invention discloses fruit fresh-keeping paper. The fruit fresh-keeping paper utilizes a fresh-keeping solution, wherein the fresh-keeping solution is prepared by adopting the following raw materials in parts by weight: 10 to 20 parts of myrrh extract, 15 to 25 parts of eucalyptus oil, 5 to 15 parts of loquat leaf extract and 2 to 10 parts of salsola collina extract. The preparation method comprises the following steps: coating a piece of raw paper with a layer of starch solution, air-curing the paper, spraying the fresh-keeping solution onto the paper in an atomizing manner, transferring the paper into a freeze drying box, adjusting the temperature to 0 to 3 DEG C, and freeze-drying the paper for 5 to 10 minutes. The fresh-keeping paper comprises a layer of starch and a fresh-keeping agent which is formed by myrrh extract, eucalyptus oil, loquat leaf extract and salsola collina extract, so that the refreshing time of fruits at a normal temperature and a low temperature can be prolonged; moreover, the flavor of the fruit can be maintained for a long time; in addition, the fresh-keeping agent adopts the traditional Chinese medicinal ingredients, thereby being natural, non-toxic and harmless to the body health.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a fruit preservation paper. Background technique [0002] Fruits are rich in nutrients and can provide humans with nutrients such as vitamins and minerals. They are one of the main non-staple foods for people. In recent years, China's fruit industry has developed rapidly, but the storage and transportation capacity of fruit freshness is seriously behind, and fruit rot causes large economic losses every year. Therefore, it is necessary to do a good job in the storage and preservation of fruits, effectively prolong the storage period of fresh fruits, ensure that the peak season is not rotten, and the off-season is continuous, so that the market can have a balanced supply every year. [0003] At present, the fresh-keeping methods of fruits mainly include chemical preservation, low-temperature storage, controlled atmosphere storage, irradiation treatment, low-temperature c...
