Problems solved by technology

[0004] However, there are a series of problems in the sales of fresh products: Gastrodia elata harvesting period is concentrated and short, and it is easy to lose the fresh food market due to the warmer weather and rainy weather, which leads to the loss of medicinal and nutritional components.
These methods can extend the storage period of Gastrodia elata to a certain extent, but the effect is not obvious, and there are certain chemical residue problems
At present, there is no report on composite fresh-keeping technology in the field of Gastrodia elata preservation

Embodiment 1

[0025] A composite fresh-keeping method for fresh Gastrodia elata, comprising the following steps:

[0026] (1) Soak the harvested fresh Gastrodia elata with 0°C composite fresh-keeping cooling liquid for 3 minutes, remove and clean Gastrodia elata in a ventilated environment at 10°C until the surface is dry; the composite fresh-keeping cooling liquid is 0.5 A mixed solution of % citric acid and 0.25% ascorbic acid;

[0027] (2) pack the Gastrodia elata with surface dryness into a fresh-keeping bag, and irradiate it with ultraviolet light with a wavelength of 253nm for 25min;

[0028] (3) The irradiated Gastrodia elata was placed in an ultra-low temperature environment of -85°C for 24 hours, then taken out and placed in an environment of -65°C for 3 days, and finally transferred to an environment of -20°C for long-term storage.

Embodiment 2

[0030] A composite fresh-keeping method for fresh Gastrodia elata, comprising the following steps:

[0031] (1) Soak the fresh Gastrodia elata after picking with 3°C composite fresh-keeping cooling liquid for 8 minutes, remove and clean Gastrodia elata and spread it in a ventilated environment of 20°C until the surface is dry; the composite fresh-keeping cooling liquid is 0.5 A mixed solution of % citric acid and 0.25% ascorbic acid;

[0032] (2) Pack the Gastrodia elata with surface drying into the fresh-keeping bag, and irradiate it with ultraviolet light with a wavelength of 254nm for 35min;

[0033] (3) The irradiated Gastrodia elata was placed in an ultra-low temperature environment of -75°C for 24 hours, then taken out and placed in an environment of -55°C for 3 days, and finally transferred to an environment of -16°C for long-term storage.

Embodiment 3

[0035] A composite fresh-keeping method for fresh Gastrodia elata, comprising the following steps:

[0036] (1) Soak the harvested fresh Gastrodia elata with 1°C composite fresh-keeping cooling liquid for 5 minutes, remove and clean Gastrodia elata and spread it in a ventilated environment at 15°C until the surface is dry; the composite fresh-keeping cooling liquid is 0.5 A mixed solution of % citric acid and 0.25% ascorbic acid;

[0037] (2) pack the Gastrodia elata with surface dryness into a fresh-keeping bag, and irradiate it with ultraviolet light with a wavelength of 253.7nm for 30min;

[0038] (3) The irradiated Gastrodia elata was placed in an ultra-low temperature environment of -80°C for 24 hours, then taken out and placed in an environment of -60°C for 3 days, and finally transferred to an environment of -18°C for long-term storage.
