Abstract

As a health-care fruit, ginkgo seeds are deeply loved by people, but due to the fact that the ginkgo seeds are bitter in taste and poor in whole fruit eating taste, the ginkgo seeds are generally processed to form deep processed products to remove the bitterness and astringency of the ginkgo seeds. For an existing method, the ginkgo seeds are mainly made into products such as cakes, tea and wine or effective ingredients of the ginkgo seeds are extracted to be taken or eaten. The invention provides a ginkgo seed crystal and a preparation method thereof. The method comprises the steps that the ginkgo seeds are hulled, and fresh ginkgo seed kernels are dried in a drying oven; dried ginkgo seed kernels are powdered and sieved, and coarse ginkgo seed powder is obtained; the obtained coarse ginkgo seed powder is further subjected to smashing, enzymolysis and drying and then smashed, and superfine ginkgo seed powder is obtained and prepared into the ginkgo seed crystal. The ginkgo seed crystal can effectively remove the bitterness and astringency of the ginkgo seeds and preserve the fragrance and sweet taste of the ginkgo seeds; the preparation method is a production method for producing ginkgo seed processed products at a low cost and can be applied and popularized on a large scale.

Description

Semen Ginkgo is brilliant and preparation method thereof
Technical field
This product relates to food processing technology field, the preparation method of a kind of Semen Ginkgo fruit.
Background technology
Semen Ginkgo (formal name used at school: Ginkgo biloba), has another name called duck bottom sediment, mental eye, Ginkgo biloba Linn.cv.Fozhi Citrus chachiensis Hort., Semen Ginkgo, Gong Sunshuzi, is Semen Ginkgo Kernel.Ellipse, long 1.5~2.5cm, wide 1~2cm, thickness about 1cm.Surface yellow-white or fallow, smooth, hard, one End slightly point, another end is blunt, and there are 2~3 crest lines at edge, and mesosperm (shell) matter is hard, endotesta film quality.One end light brown, another end is golden yellow Color.Kernel mealiness, middle have little core, sweet in the mouth, micro-hardship.Main product in Jiangsu, Guangxi, Sichuan, Henan, Shandong, the ground such as Hubei.
Semen Ginkgo, has another name called Semen Ginkgo, is a kind of conventional Chinese medicine, has medicine food with the feature of merit, as dietetic therapy, nourishes, keeps healthy The food history of existing more than 1000 year.Modern study shows, Semen Ginkgo material Han ginkgolic acid, Ginnol etc., can prevent cardiovascular and cerebrovascular vessel Disease, prevents thrombosis, delays arteriosclerosis progress;Wheat Protein, energy looks improving and the skin nourishing, slow down aging, suppresses black Element, accelerates skin metabolism, prevents the generation of wrinkle;Can also antiallergic, anti-inflammation and sterilization.Semen Ginkgo kernel is except containing starch, egg Outside white matter, fat, saccharide, possibly together with trace element such as vitamin C, riboflavin, carotene, calcium, phosphorus, ferrum, potassium, magnesium and Ginkgoic acid, bilobol, five carbon polysaccharide, the composition such as fat sterin, nutritious, and for lung benefiting gas, control cough with asthma, leukorrhagia stopping worm, contracting Urine, flat chapped wrinkle, protect blood vessel, increase the diseases such as blood flow, leukorrhagia, nebulousurine there is good medical effect and dietary function.
As a kind of Healthcare fruit, Semen Ginkgo is liked by the common people deeply, but owing to its taste is the most bitter, whole fruit eating mouth feel is the best, Typically Semen Ginkgo is processed, formed deep processed product remove its bitter taste, existing method be mainly made into cake, tea, Goods such as wine or out carry out its extracts active ingredients taking or eating.But prior art by while its deep processing one is Destroying the local flavor of original Semen Ginkgo, two are formed into tea, wine, cake etc. needs relatively multiple operation, and processing link is more and destroys white The mouthfeel that fruit is edible.
Summary of the invention
The present invention is directed to above-mentioned technical problem, it is provided that a kind of processing technology link is few, Semen Ginkgo effective ingredient runs off less, holding The Semen Ginkgo crystalline substance its preparation method of Semen Ginkgo peculiar flavour.
The solution of the present invention is by being achieved in that: the preparation method that a kind of Semen Ginkgo is brilliant, it is characterised in that following technique Step:
