Problems solved by technology

[0006] Ginkgo biloba is not a vegetable, and it contains a lot of ginkgolic acid. Ginkgo biloba is toxic. Ginkgo biloba has a high fiber content. If you only add carboxymethyl cellulose, sodium alginate, gelatin, etc. agent, not only can not prepare ginkgo leaf edible wrapping paper that meets the requirements, but also cause a large amount of active ingredients in ginkgo leaf to be inactivated or lost. The present invention proposes a method for preparing wrapping paper suitable for ginkgo leaf, which can Toxic ingredients in Ginkgo biloba are removed, and the traditional health care and active ingredients in Ginkgo biloba are retained in the packaging paper

Embodiment 1

[0027] The present embodiment provides a kind of preparation method of the ginkgo leaf edible wrapping paper of nontoxic high flavonoid content, and described preparation process is as follows:

[0028] Raw material pretreatment: choose fresh ginkgo leaves without pests, wash the ginkgo leaves 3 to 6 times, and remove the leaf stems: prepare a salicylic acid solution with a salicylic acid content of 0.5% with boiling water, and wash the ginkgo leaves with boiling salicylic acid Blanch in acid solution for 10 minutes until soft, take out, rinse with pure water at 10°C, and drain to obtain pretreated ginkgo leaves;

[0029] Beating: Put the pretreated ginkgo leaves into the pulverizer, pulverize for 3 minutes, so that the leaves are cut off; after pulverization, transfer the ginkgo leaves to the beater, add phenylalanine solution for beating according to the ratio of solid to liquid 1:2, Wherein, the phenylalanine content of the phenylalanine solution is 0.5%, the beater speed i...

Embodiment 2

[0050] The present embodiment provides a kind of preparation method of the ginkgo leaf edible wrapping paper of nontoxic high flavonoid content, and described preparation process is as follows:

[0051] Raw material pretreatment: choose fresh ginkgo leaves without pests, wash the ginkgo leaves 3 to 6 times, and remove the leaf stems: prepare a salicylic acid solution with a salicylic acid content of 1% with boiling water, and wash the washed ginkgo leaves with boiling salicylic acid Blanch in acid solution for 20 minutes until soft, take out, rinse with distilled water at 4°C, and drain to obtain pretreated ginkgo leaves;

[0052] Beating: Grinding with a pulverizer for 2 minutes, then adding the crushed ginkgo leaves to the phenylalanine solution at a material-to-liquid ratio of 1:3, mixing and beating, and homogenizing with a colloid mill after beating to obtain ginkgo leaf slurry. Wherein, the phenylalanine content of the phenylalanine solution is 0.2%, the beater speed is ...

Embodiment 3

[0060] The present embodiment provides a kind of preparation method of the ginkgo leaf edible wrapping paper of nontoxic high flavonoid content, and described preparation process is as follows:

[0061] Raw material pretreatment: select fresh ginkgo leaves without pests, wash the ginkgo leaves 3 to 6 times, and remove the leaf stems: prepare a salicylic acid solution with a salicylic acid content of 0.2% with boiling water, and wash the washed ginkgo leaves with boiling salicylic acid Blanch in acid solution for 6 minutes until soft, take out and rinse with distilled water at 20°C and drain to obtain pretreated ginkgo leaves;

[0062] Beating: Grinding with a pulverizer for 2 minutes, then adding the crushed ginkgo leaves to the phenylalanine solution according to the ratio of material to liquid at 1:1, mixing and beating, and homogenizing with a colloid mill after beating to obtain ginkgo leaf slurry. Wherein, the phenylalanine content of the phenylalanine solution is 0.8%, t...

Abstract

The invention provides nontoxic high-flavonoid-content ginkgo leaf edible packing paper, and belongs to the technical field of vegetable paper. The ginkgo leaf edible packing paper is prepared by mixing ginkgo leaf stuff with a ginkgo leaf paper forming agent, wherein the ginkgo leaf stuff contains phenylalanine, and the formula of the ginkgo leaf paper forming agent comprises the following components in percentage by weight: 0.10-0.20% of carboxymethyl cellulose, 0.10-0.20% of sodium alginate, 0.20-0.40% of gelatin, and 0.05-0.1% of polydimethylsiloxane. The invention also provides a preparation method of the nontoxic high-flavonoid-content ginkgo leaf edible packing paper, and the preparation method specifically comprises the following steps: blanching cleaned ginkgo leaves by using a boiling salicylic acid solution, adding phenylalanine for defibrination and homogenization treatment, preparing a compound paper forming agent, mixing the compound paper forming agent with the ginkgo leaf stuff uniformly, performing coating, drying and forming processes, performing impregnation in a propanetriol solution, and performing drying again to obtain the nontoxic high-flavonoid-content ginkgo leaf edible packing paper.

Description

technical field [0001] The invention belongs to the technical field of edible wrapping paper, and in particular relates to a nontoxic ginkgo leaf edible wrapping paper with high flavonoid content and a preparation method thereof. Background technique [0002] Ginkgo biloba is the leaf part of Ginkgo biloba. Ginkgo biloba has important medicinal value. It contains a variety of medicinal ingredients, such as: ginkgo flavonoids, terpenoid lactones, alkaloids, linoleic acid, phenols, quinic acid , ascorbic acid, ginkolic acid, ginkgo ketone, etc. These substances have pharmacological effects such as lowering serum cholesterol, inhibiting platelet viscosity, regulating vascular tension and elasticity, relieving smooth muscle spasm, relaxing bronchi and antibacterial, lowering serum cholesterol, inhibiting platelet viscosity, regulating Vascular tension, improve circulation, promote the health of the nervous system, promote the recognition ability of the nervous system, scavenge p...
