Abstract

The invention discloses a dendrobium candidum stem preservative. The preservative comprises the following components in parts by mass: 3-5 parts of sucrose ester, 1-2 parts of citric acid, 0.01-0.05 part of sodium glutamate, 0.05-0.1 part of aminobutyric acid, 0.6-0.8 part of ascorbic acid, 0.5-0.6 part of sodium ascorbate, 5-8 parts of sesbania gum, 4-7 parts of peach gum and 20-30 parts of water. By a preservation method provided by the invention, the preservation period can be as long as 400 days or above; through the action of the preservative, active components are prevented from being destroyed by frostbite in the freezing process, so that the original taste and the active components of fresh strips are completely maintained.

Description

technical field [0001] The invention belongs to the field of dendrobium cultivation, and in particular relates to a fresh-keeping agent and a fresh-keeping method for stems of dendrobium candidum. Background technique [0002] Dendrobium officinale (Deudrobium officiuale) is a perennial epiphytic herb of the genus Dendrobium orchidaceae. Qi, long muscles, intelligence and shock, light body and prolong life"; folks call it "life-saving celestial grass". It is mostly distributed on the semi-shady and damp rocks in the mountains at an altitude of nearly 1,000 meters. In addition to long-term excavation, the resources of wild Dendrobium candidum are gradually exhausted. Therefore, the price of high-grade Dendrobium candidum is extremely high and its medicinal value is great. [0003] The stems (fresh strips) of Dendrobium candidum can be chewed directly, can also be added to purified water to squeeze juice for drinking, and can also be eaten in soup and porridge. Moisture is a...
