Problems solved by technology

However, there is a big difference between Dendrobium officinale for processing and fresh strips. Fresh strips still maintain certain physiological and metabolic activities during storage.
The storage methods of fresh strips of Dendrobium candidum are mostly aimed at the problems such as the inhibition of the physiological metabolism of vigorous Dendrobium tissues. If the storage method of fresh strips of Dendrobium candidum is used to store Dendrobium candidum for processing, there are few storage methods for Dendrobium candidum for processing. to report

Embodiment 1

[0022] A storage method of Dendrobium candidum for processing described in this example comprises the following steps: select fresh dendrobium strips with a polysaccharide content greater than 30%, uniform length, no pests and mechanical damage, and dry the fresh dendrobium strips at a temperature of 70°C for 2 After 1 hour, remove and cool to below 20°C. Put the cooled Dendrobium officinale into a 0.5cm thick corrugated cardboard box, add citral preservative at a ratio of 1% by mass, seal it and store it at -2°C ice temperature, and control the ambient humidity at 70% until the storage period At the end, 3 batches of repeated samples were taken for testing.

[0023] The citral antistaling agent described therein is obtained by the following method: 10g of citral is added in 40g of ether and mixed uniformly, then the citral solution is added into 100g of diatomite, stirred evenly and evaporated to the surface of diatomite under reduced pressure It is dry, weighed according to...

Embodiment 2

[0030] A storage method of Dendrobium candidum for processing described in this example comprises the following steps: select fresh dendrobium strips with a polysaccharide content greater than 30%, uniform length, no pests and mechanical damage, and dry the fresh dendrobium strips at 75°C for 2 After 1 hour, remove and cool to below 20°C. Put the cooled Dendrobium officinale into a 0.4cm thick corrugated cardboard box, add citral preservative at a ratio of 0.5% by mass, seal it and put it in -4°C ice temperature for storage, and control the ambient humidity at 75% until the storage period End, get repeated sample 3 batches and detect, the result shows that reaches the technical effect of embodiment 1.

Embodiment 3

[0032] A storage method of Dendrobium candidum for processing described in this embodiment comprises the following steps: select fresh dendrobium strips with a polysaccharide content greater than 30%, uniform length, no pests and mechanical damage, and dry the fresh strips of Dendrobium at 80°C for 1.5 After 1 hour, remove and cool to below 20°C. Put the cooled Dendrobium officinale into a 0.3cm thick corrugated cardboard box, put citral preservative in a proportion of 0.1% by mass, seal it and put it in -5°C ice temperature for storage, and control the ambient humidity at 80% until the storage period End, get repeated sample 3 batches and detect, the result shows that reaches the technical effect of embodiment 1.

Abstract

The invention designs a method for storing dendrobium officinale for processing. The method comprises the following steps: picking fresh strips of dendrobium officinale; screening to obtain fresh strips of dendrobium officinale with a polysaccharide content greater than 30%, consistent length, no pests and diseases and no mechanical injuries; taking the screened fresh strips of dendrobium officinale; heating and drying at 70-80 DEG C for 1.5-2 hours; keeping the moisture of the fresh strips of dendrobium officinale at 65-80% and keeping the water activity at 0.5-0.65; taking out and cooling the fresh strips of dendrobium officinale to below 20 DEG C after reaching the corresponding water activity; placing the cooled dendrobium officinale for processing into a 0.3-05 thick corrugated box; placing a citral preservative at a mass ratio of 0.1-1%; sealing an opening and placing at an ice temperature of -5 to -2 DEG C for storage; and controlling the environmental humidity at 70-85%. The storage method designed in the invention adopts a comprehensive control technology of pre-controlling the water activity combined with plant essential oil to solve a storage problem of the dendrobium officinale for processing and relieve the production pressure of enterprises in a harvesting peak period.

Description

technical field [0001] The invention belongs to the technical field of freshness preservation in the storage and processing of agricultural products, and in particular relates to a storage method for dendrobium officinale for processing. Background technique [0002] Dendrobium officinale Kimura et Migo, also known as black knot grass, belongs to the genus Dendrobium officinale, is a perennial epiphytic herb of Orchidaceae, and is a precious wild medicinal plant. Due to its unique value and efficacy, Dendrobium candidum was honored as the first of the "Nine Chinese Immortal Herbs" by the Taoist classic "Dao Zang" as early as the Kaiyuan period of the Tang Dynasty. "Shen Nong's Materia Medica" listed Dendrobium candidum as the top grade, pointing out that it has the effects of promoting body fluid, quenching thirst, analgesia, and eliminating edema; ". "Chinese Pharmacopoeia" records that Dendrobium candidum can benefit the stomach and promote body fluid, nourish yin and cl...
