Problems solved by technology

First of all, most of the natural preservatives used are crude products, and the active ingredients in them have not been thoroughly studied; secondly, the research on the mechanism of action, antibacterial spectrum and applicable range of various natural preservatives is not comprehensive enough, and some Some natural antistaling agents have narrow antibacterial spectrum, poor antiseptic and fresh-keeping effect, complicated manufacturing process, and high production cost; thirdly, some natural antistaling agents cannot achieve the fresh-keeping effect when the amount is small, and will affect the flavor and quality of food when the amount is large, and even produce toxic side effect

Embodiment 1

[0018] Add 650kg Gastrodia elata extract to the 1000L reactor, then put in 80kg cortex phellodendron and 90kg magnolialine, stir to dissolve, then slowly add 55kg of vitamin C and 55kg of olive oil, stir to dissolve, then put in 70kg of peach gum, stir to dissolve Evenly, the final product containing gastrodia elata preservative can be obtained. The Gastrodia elata extract is prepared by the following method: soak Gastrodia elata for 8 hours, then heat to 130°C and decoct for 40 minutes, filter through filter paper to remove dregs, collect the filtrate, and directly spray dry to obtain the Gastrodia elata extract.

Embodiment 2

[0020] Add 720kg Gastrodia elata extract into the 1000L reactor, then add 30kg cortex phellodendriline, 40kg jatrorrhizine, 40kg formononetin and 40kg magnolialine, stir to dissolve, then slowly add 40kg vitamin B2 and 40kg olive oil, stir to dissolve Finally, drop into 50kg peach gum again; Stir and dissolve evenly, obtain the antistaling agent that the final product contains Gastrodia elata. The Gastrodia elata extract is prepared by the following method: soak Gastrodia elata for 9 hours, then heat to 125° C. and decoct for 35 minutes, filter through filter paper to remove dregs, collect the filtrate, and directly spray dry to obtain the Gastrodia elata extract.

Embodiment 3

[0022] Add 701kg Gastrodia elata extract in 1000L reactor, then drop into 50kg cortex phellodendriline, 50kg jatrorrhizine and 55kg formononetin, after stirring and dissolving, slowly drop into 45kg vitamin C and 45kg campesterol, after stirring and dissolving, then 30kg of peach gum and 24kg of agar are put into the mixture; stirred and dissolved evenly to obtain the preservative containing Gastrodia elata as the final product. The Gastrodia elata extract is prepared by the following method: soak Gastrodia elata for 10 hours, then heat to 115° C. and decoct for 30 minutes, filter through filter paper to remove dregs, collect the filtrate, and directly spray dry to obtain the Gastrodia elata extract.

Abstract

The invention relates to a fresh-keeping agent containing rhizoma gastrodiae, which belongs to processing technical field of the fresh-keeping agent. The fresh-keeping agent is characterized by comprising the following ingredients by weight percent: 61 to 75 percent of rhizome gastrodiae extract, 12 to 19 percent of sterilization components, 6 to 13 percent of synergistic components and 3 to 9 percent of film-forming components. According to the fresh-keeping agent containing the rhizome gastrodiae, the pure natural rhizome gastrodiae extract is adopted as an active ingredient and is mixed with the natural sterilization, synergistic and film-forming components to prepare the fresh-keeping agent. The fresh-keeping agent has a fresh-keeping and preservative function and has a good fresh-keeping action on fruits, meat, seafood and vegetables. Due to the adoption of the fresh-keeping agent, the rotting speed of the food can be slowed down, moisture evaporation of the vegetables and fruits can be reduced, and wilting of the vegetables and fruits can be prevented; and meanwhile, a layer of uniform film can be formed on the surface of the food after being processed with the fresh-keeping agent, and the film is toxic-free and edible, so that the storage period can be effectively prolonged. The fresh-keeping agent has a simple processing method, less investment on equipment, guaranteed source of raw materials and low production cost and is safe and pure natural.

Description

technical field [0001] The invention belongs to the technical processing field of antistaling agents, in particular to an antistaling agent containing Gastrodia elata. Background technique [0002] In the process of production and storage, food is extremely susceptible to microbial infection, oxidation, etc., which will lead to spoilage and cause serious economic losses. At present, the commonly used preservatives can be divided into chemical preservatives and natural preservatives from the source. Although chemical preservatives have fast effects and are easy to use, there are some safety hazards, and their residues will also cause chemical pollution. While having a high antiseptic and fresh-keeping effect, it often has a negative impact on human health, and even short-term or even long-term hazards such as carcinogenicity, teratogenicity, and mutagenesis. Therefore people turn their eyes to the development of the natural antiseptic preservative with little side effect and...
