Embodiment 1

[0028] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0029] (1) Pick 7-8 mature mulberries, pick fruits with uniform size, no rot, no pests and diseases, and no mechanical damage, and put them into PET plastic boxes with a thickness of 0.34mm. The height of the fruit is 10cm, and the temperature is -1~ Under the condition of ice temperature of 0°C, open and pre-cool for 4 hours, and the temperature of mulberry reaches 0°C,

[0030] (2) After opening and precooling, add p-cymene to the PET plastic box. The amount of p-cymene is 50 μL / L relative to the volume of the PET plastic box. In a small-volume clean container, without direct contact with the mulberry fruit, quickly cover the airtight plastic box, and then place it at a temperature of 0-2°C until the end of storage.

[0031] Three batches of duplicate samples were taken for testing.

Embodiment 2

[0040] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0041] (1) Pick 7-8 mature mulberries, choose fruits with uniform size, no rot, no pests and diseases, and no mechanical damage, and put them into a PET plastic box with a thickness of 0.30mm. The height of the fruit is 8cm, and the temperature is -1~ Under the condition of ice temperature of 0°C, open the door and pre-cool for 1 hour, and the temperature of the mulberries will reach 2°C.

[0042] (2) After opening and precooling, add p-cymene to the PET plastic box. The amount of p-cymene is 40 μL / L relative to the volume of the PET plastic box. In a small-volume clean container, without direct contact with the mulberry fruit, quickly cover the airtight plastic box, and then place it at a temperature of 0-2°C until the end of storage.

[0043] Three batches of duplicate samples were taken for testing. The test result shows that the effect of Example 1 is reached, so no further...

Embodiment 3

[0045] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0046] (1) Pick 7-8 mature mulberries, choose fruits with uniform size, no rot, no pests and diseases, and no mechanical damage, and put them into PET plastic boxes with a thickness of 0.36mm. The height of the fruit is 12cm, and the temperature is -1~ Under the condition of ice temperature of 0°C, open for pre-cooling for 4 hours, and the temperature of mulberry reaches 1°C.

[0047] (2) After opening and precooling, add p-cymene to the PET plastic box. The amount of p-cymene is 60 μL / L relative to the volume of the PET plastic box. In a small-volume clean container, without direct contact with the mulberry fruit, quickly cover the airtight plastic box, and then place it at a temperature of 0-2°C until the end of storage.

[0048] Three batches of duplicate samples were taken for testing. The test result shows that the effect of Example 1 is reached, so no further details are ...

Abstract

The invention belongs to the field of fresh keeping of fruits and vegetables, and discloses a fresh keeping method for mulberry. The method comprises the following steps of: picking medium mulberry, putting into a polyethylene terephthalate (PET) plastic box, performing quick ice temperature pre-cooling under the condition that the plastic box is open, adding p-cymene, quickly covering the plastic box, and storing at a low temperature. By the method, the respiration intensity of the mulberry can be effectively inhibited, hardness of fruits is kept, and rot is reduced; after the mulberry is stored for 15 days by adopting the method, high quality of the fruits is still kept, and the rotting rate is only 4.4 percent; and the method is high in safety and easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping method of mulberries. Background technique [0002] Mulberry is the moraceae plant mulberry ( Morus alba L.) mature ears are mainly concentrated in Jiangsu, Zhejiang, Hunan, Sichuan, Hebei and other places in my country. Mulberry is fresh and delicious, containing VC, VE, β-carotene, flavonoids and trace elements and other nutrients. It is one of the first batch of medicinal and edible agricultural products approved by the Ministry of Health as "both food and medicine". But mulberry matures in the high temperature and rainy season, the fruit is tender and juicy, without the protection of exocarp, it is vulnerable to mechanical damage and germ infection after harvesting, and its respiration is strong. It will change color, soften and rot after being placed at room temperature for 1-2 days. very serious. Research and development of...
