Embodiment 1

[0015] Embodiment one: Ginkgo biloba pretreatment refers to that Ginkgo biloba is pretreated through following one or more steps.

[0016] (1), Ginkgo biloba leaves are cleaned, dried, and can also be crushed through a 20-80 mesh sieve.

[0017] (2) Ginkgo biloba is treated with cellulase to degrade the macromolecular cellulose in ginkgo biloba into soluble fragments with smaller molecular weight, destroy the cell wall, and fully release intracellular dissolved substances without destroying nutrients and active ingredients.

[0018] (3) Ginkgo leaves are extracted with low-polarity organic solvents such as petroleum ether and n-hexane to remove toxic substances such as ginkgolic acid and fat-soluble impurities.

[0019] (4) Ginkgo leaves are added with or without C and N sources in an appropriate amount, inoculated with medicinal and edible fungi and other beneficial microorganisms, and obtained by solid fermentation to obtain Ginkgo biloba fungus leaves. The fungus leaves co...

Embodiment 2

[0021] Embodiment two, raw material ginkgo leaf extract residue in above example is through low-temperature drying, also can be equipped with appropriate flavoring agent and other auxiliary materials, be processed into debittering ginkgo leaf residue powder.

Embodiment 3

[0022] Embodiment three, debittering Ginkgo biloba residue is soaked in or sprayed under stirring the debittering Ginkgo biloba extract extract or its ethanol dilution, dry at low temperature to obtain debittering Ginkgo biloba or pulverize into powder at low temperature, also can debittering Ginkgo biloba Ginkgo biloba residue powder is mixed with debittered ginkgo leaf extract powder to be processed into debittered ginkgo biloba composite powder.

Description

technical field [0001] The invention relates to a preparation method of a debittered ginkgo leaf product and the product thereof. Background technique [0002] Ginkgo biloba contains flavonoids, terpene lactones, polyprenyl alcohols, polysaccharides and other functional ingredients; Ginkgo biloba contains vitamin C, vitamin E, carotene, calcium, phosphorus, boron, selenium and other mineral elements Very rich, more than common fruits, vegetables and edible plant materials; Ginkgo biloba has high protein content, reasonable amino acid composition, contains 9 kinds of essential amino acids, and the ratio of essential amino acids to total amino acids is about 40%, and essential amino acids account for non-essential amino acids The amino acid ratio is over 66%. Ginkgo biloba protein quality is better than the FAO / WHO scoring model, comparable to soybean protein, and very close to egg protein; Ginkgo biloba is also rich in plant fiber. [0003] Ginkgo biloba extract is limited i...
