Ganoderma lucidum-ginkgo functional food and preparation method thereof

Abstract

The invention discloses a ganoderma lucidum-ginkgo functional food and a preparation method thereof, and the process relates to the field of biological engineering technology. With ginkgo as main raw material and by adopting strain liquid deep culture and solid fermentation technologies, the ganoderma lucidum-ginkgo functional food is obtained. The preparation method comprises the steps: cutting ginkgo into small lumps with the size of 3-5 mm, inoculating with a 5-30% ganoderma lucidum seed liquid after sterilization, carrying out sealed fermentation with a preservative film, and after drying and smashing the fermentation product, thus obtaining the ganoderma lucidum-ginkgo functional food. The product contains 0.3-2 mg / g of total flavonoids, 0.2-1.5 mg / g of ginkgolides, 0.8-3.9 mg / g of ganoderma trierponoides, 0.9-8 mg / g of proteins, less than 0.5% of soluble sugar, 1-15 mg / g of polysaccharide, less than 5 [mu]g / g of ginkgolic acid, and less than 0.1 [mu]g / g of hydrocyanic acid. Because of containing the flavonoid compounds, terpenoids, ganoderma triterpenes and other active ingredients, the product has the efficacies of inhibiting tumor cell reproduction and reducing oxidative stress in a body.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a method of using ganoderma lucidum to expand the number of ganoderma strains using liquid technology, and then transforming ginkgo ginkgo fruit to produce ginkgo ginkgo functional food through solid fermentation technology and the use of the food. Background technique [0002] The main components of ginkgo biloba are protein, starch and fat, and it also contains flavonoids, terpenoids, ginkgolic acid, hydrogenated ginkgo acid, hydrogenated ginkgo acid, ginkgo alcohol, ginkgool and polysaccharides. Ancient books of traditional Chinese medicine in my country have always listed ginkgo as an important medicinal material. Ginkgo acid inhibits a variety of bacilli and skin fungi, and has different degrees of resistance to staphylococcus, streptococcus, diphtheria, anthrax bacillus, Bacillus subtilis, Escherichia coli, typhoid bacteria, etc. inhibitory effect. Ginkgo phenolic ...
