Embodiment 1

[0055] A kind of fresh-keeping method of dendrobium candidum, it comprises the steps:

[0056] S11: Harvested at the planting base of Guangdong Yongshengyuan Biotechnology Co., Ltd., select raw Dendrobium candidum of 1-2 years, and remove the leaves of the Dendrobium candidum after picking, wash and drain the water for later use;

[0057] S12: Place the cleaned Dendrobium candidum in 75% edible ethanol at 3°C ​​for 3, 5, and 10 minutes to sterilize;

[0058] S13: the Dendrobium candidum after the disinfection and sterilization treatment is air-dried under an ultraviolet lamp, and then packed in a fresh-keeping bag with a PVC single side thickness of 0.03mm, about 20-30g per bag, and pre-cooled in a cold storage at about 3°C ​​for 1-20g after packing. After 2 hours, refrigerate at 0±0.5°C, 1±0.5°C, 3±0.5°C, and 5±0.5°C respectively.

Embodiment 2

[0060] A kind of fresh-keeping method of dendrobium candidum, it comprises the steps:

[0061] S21: picking at the planting base of Guangdong Yongshengyuan Biotechnology Co., Ltd., selecting 1-2 years raw Dendrobium candidum, and removing the leaves of the picked Dendrobium candidum, cleaning and draining the water for later use;

[0062] S22: the Dendrobium officinale after cleaning is placed in 75% edible ethanol at 3° C. and soaked for 3 minutes for sterilization;

[0063] S23: The Dendrobium candidum after the disinfection and sterilization treatment is air-dried under an ultraviolet lamp, and then packed in a fresh-keeping bag with a thickness of 0.03mm on one side of LDPE, about 20-30g per bag, and pre-cooled in a cold storage at about 3°C ​​for 1-2 hours after packing. Refrigerate at 5±0.5°C after 2 hours.

Embodiment 3

[0065] A kind of fresh-keeping method of dendrobium candidum, it comprises the steps:

[0066] S31: picking at the planting base of Guangdong Yongshengyuan Biotechnology Co., Ltd., selecting 1-2 years raw Dendrobium candidum, and removing the leaves of the picked Dendrobium candidum, cleaning and draining the water for later use;

[0067] S32: the Dendrobium candidum after cleaning is placed in 75% edible ethanol at 2°C and soaked for 5 minutes to carry out sterilization treatment;

[0068] S33: The Dendrobium candidum after the disinfection and sterilization treatment is air-dried under an ultraviolet lamp, and then packed in a fresh-keeping bag with a PVC single-sided thickness of 0.03mm, about 20-30g per bag, and pre-cooled in a cold storage at about 3°C ​​for 1-30g after packing. Refrigerate at 3±0.5°C after 2 hours.

Abstract

The invention discloses a method for preserving dendrobium officinale. The method comprises the following steps: removing leaves of picked dendrobium officinale, and washing; precooling, disinfecting and sterilizing the washed dendrobium officinale; draining the disinfected and sterilized dendrobium officinale in an aseptic condition, performing aseptic packaging, and refrigerating. According to the method for preserving dendrobium officinale, the preservation period of the dendrobium officinale can be prolonged to over 6 months, the original ingredients, color and crispness can be effectively maintained, the weight loss ratio is low, and the commercial value of the dendrobium officinale can be guaranteed. Furthermore, the method cannot generate harmful substance residues, and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a fresh-keeping method of dendrobium candidum. Background technique [0002] With the development of the Dendrobium candidum planting industry, the output of Dendrobium candidum is also increasing year by year, and the problem of product preservation faced by planting enterprises in the process of fresh product storage, sales and transportation is becoming increasingly prominent. It has been reported that with the increase of planting years, the content of functional components such as alkaloids and polysaccharides in Dendrobium candidum will gradually increase. In terms of planting cost and functional ingredient content, growers and planting companies generally choose to plant for 1 to 2 years for harvesting. Dendrobium candidum germinates new shoots every spring, and fresh strips of the new Dendrobium candidum can be harvested in wint...
