Problems solved by technology

[0004] In summary, there are technical problems in the prior art: fresh Gastrodia elata is not resistant to storage, it is very perishable, and it can only be stored for 3-5 days at normal temperature.
At present, there are few studies on the preservation of fresh Gastrodia elata, and the existing preservation methods applied to block lotus medicinal materials mainly include: 1-methylcyclopropene (1-MCP) + smoking time + dosage of Gastrodia elata, the storage time is 31 days, and the storage time is short. Moreover, the residual problem of sulfur smoking is worthy of attention; adding preservatives + steaming, the storage time is 80 days, and the loss of nutrition caused by steaming cannot be ignored; the storage time is 40 days in a transparent plastic bag, and the storage time is short; PE20 fresh-keeping bag storage, storage Time 65d, short storage time
At present, there is no storage method for Gastrodia elata with a storage time of more than 4 months

[0033] Composite treatment method for cold chain preservation of Gastrodia elata

[0034] Pretreatment of Fresh Gastrodia elata

[0035] Fresh Gastrodia elata was harvested in Zhaotong City, Yunnan Province in January 2019. After harvesting, remove the field heat of Gastrodia elata in time to avoid fever and sweating. Harvested Gastrodia elata was transported to the laboratory for cleaning in time. When cleaning, wear rubber gloves and gently scrub with a soft cloth to ensure that the outer skin is not damaged. Gastrodia elata with no mechanical damage, no pests and diseases, healthy and uniform size was selected as the experimental material. Use the selected Gastrodia elata with O 3 Disinfect for 5 minutes; take it out and let it dry naturally. Place Gastrodia elata in a 4°C refrigerator for precooling for 12 hours, and wait until the required storage temperature is reached.

Abstract

The invention discloses a compound treatment method for cold-chain preservation of gastrodia elata and relates to the technical field of gastrodia elata preservation. The compound treatment method forcold-chain preservation of the gastrodia elata comprises the following steps: preservation pretreatment of fresh gastrodia elata, compound preservation treatment of the gastrodia elata, modified atmosphere packaging treatment and preservation storage of the gastrodia elata. By combination of Nisin and herba sphagni with modified atmosphere treatment, the compound treatment method can effectivelyreduce the weight loss ratio and the rot index, has higher water retention and antibacterial functions, can prolong the refreshing time of the gastrodia elata to 120 days or longer, and is suitable for industrial promotion and application.

Description

technical field [0001] The invention relates to the technical field of gastrodia elata preservation, in particular to a composite processing method for gastrodia elata cold chain preservation. Background technique [0002] Gastrodia elata Blume (Gastodia elata Blume) is a perennial heterotrophic herb without green leaves. The height of Gastrodia elata Blume produced in Sichuan, Tibet and other places is generally 50-150cm. The underground block lotus grows horizontally, round or oval, and the flesh is thicker, with nodes, and membranous scales grow in whorls on the nodes. Gastrodia elata can be divided into 6 varieties according to the water content of the tuber, the shape of the tuber, the color of the flower, and the color of the flower stem. Gastrodia elata is used as medicine with tubers, which is a traditional precious Chinese medicine in my country and has been included in the "Chinese Pharmacopoeia" in previous editions. According to the records of "Compendium of Ma...
