Problems solved by technology

At present, ginkgo peeling is usually manually peeled after soaking in water, or smashed with sticks, baskets and other tools, and cleaned. This method is not only labor-intensive, but the peeling efficiency is low, and the core is easily damaged, and the juice is easily corroded Parts that come into contact with the skin are harmful to the human body
[0004] At present, most of the ginkgo fruit outer seed coats are peeled off and stacked in the open air. Under rainwater immersion, the toxic components of phenolic acids contained in them are leached by water and discharged into the river ditch, which not only affects the surrounding environment of the storage site, but also has an unpleasant smell. Cause waste of resources, and more importantly, cause pollution to surrounding waters, poison fish and shrimp, threaten the safety of drinking water for humans and animals, and have reached the point where it must be solved. If the outer testa of ginkgo is not treated harmlessly, it will Industrialization of Ginkgo Processing
Therefore, it is an urgent task to promote the further industrialization of ginkgo processing by how to rationally utilize the resources of the ginkgo outer testa, manage the environment, and improve the environment. Systematic studies and reports have not yet been seen

[0036] The culture medium of EM bacteria liquid is composed of the following components by mass percentage: 3% brown sugar, 0.5% edible urea, 0.12% vitamin K, 0.08% cysteine, 0.12% zinc, and the balance is water; The water is prepared by boiling distilled water and cooling to 23-25°C.

[0037] The preparation process of the EM bacterial liquid is as follows: Inoculate the EM original dew into the above-mentioned medium with an inoculum amount of 1%, stir evenly, keep the temperature at 35°C-37°C for sealed culture, deflate once every 22-24 hours, and when the solution When the pH value is 5.0, the fermentation is stopped, and the EM bacterial liquid with the number of viable bacteria of 8-12 billion / ml is prepared.

[0038] (1) Weigh 100kg of mature fresh ginkgo fruit, put it into a container, add 150L EM bacteria liquid, stir evenly, and keep the temperature at 40°C for 2 hours of fermentation;

[0039] (2) After the fermentation in step (1), remove the ginkgo fruit and coll...

Embodiment 3

[0042] The culture medium of EM bacteria liquid is composed of the following components by mass percentage: brown sugar 2.5%, edible urea 0.8%, vitamin K 0.12%, cysteine ​​0.08%, zinc 0.12%, and the balance is water; The water is prepared by boiling distilled water and cooling to 23-25°C.

[0043] The preparation process of the EM bacterial liquid is as follows: Inoculate the EM original dew into the above-mentioned medium with an inoculation amount of 3%, stir evenly, keep the temperature at 35°C-37°C for sealed culture, deflate once every 22-24 hours, and when the solution When the pH value is 4.0, the fermentation is stopped, and an EM bacterial liquid with a viable count of 100-120 / ml is prepared.

[0044] (1) Weigh 100kg of mature fresh ginkgo fruit, put it into a container, add 100L EM bacteria liquid, stir evenly, and keep the temperature at 35°C for 12 hours of fermentation;

Abstract

The invention belongs to the technical field of bio-fermentation, and in particular relates to ginkgo biloba exocarp fermentation liquid as well as a preparation method and an application thereof. The preparation method of the ginkgo biloba exocarp fermentation liquid comprises the following steps: (1) adding EM bacterium liquid to fresh ginkgo biloba fruits, uniformly stirring the EM bacterium liquid and the fresh ginkgo biloba fruits, preserving temperature and conducting fermentation; (2) after conducting the fermentation in the step (1), taking out the ginkgo biloba fruits, and collecting fermentation liquid 1; and (3) crushing exocarp of the ginkgo biloba fruits obtained in the step (2) and squeezing out kernels, collecting the ginkgo biloba exocarp, milling the ginkgo biloba exocarp into slurry in the fermentation liquid 1 obtained in the step (2), preserving heat and conducting fermentation, so that the ginkgo biloba exocarp fermentation liquid is obtained. The preparation method provided by the invention is simple to operate, free from the generation of bad smell, free from the discharge of sewage and easy for industrial production. The ginkgo biloba exocarp fermentation liquid prepared by the invention is good in sterilizing effect, rich in nutrition and free from environmental pollution, and the ginkgo biloba exocarp fermentation liquid can be applied to medicines or fertilizers.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a ginkgo exocarp fermented liquid and a preparation method and application thereof. [0002] technical background [0003] Ginkgo biloba is one of the oldest existing Mesozoic relict plants on the earth. It is a tree species with both seeds, leaves and materials. Its seeds are also called ginkgo or ginkgo. Due to the high practical and medicinal value of ginkgo biloba and seeds, they have been paid attention to at home and abroad, and the production scale has been continuously expanded. my country currently has a large area of ​​ginkgo planting, and the annual output of ginkgo accounts for more than 90% of the world's total output, and the annual output of fresh ginkgo is more than 100,000 tons. Ginkgo biloba's testa extract has an inhibitory rate of 88% to 100% against 11 kinds of plant pathogens such as apple anthracnose. The alcohol extract has a 1...
