Description
Technical field
The present invention relates to Ganoderma lucidum submerged fermentation mycelium field, is the method that a kind of Ganoderma lucidum submerged fermentation mycelium improves output and micro-enrichment.
Background technology
The consciousness of living with health of people along with developing rapidly of China's economy improves, under current allegro working method, the dysbolism that the bad habits and customs that different crowd forms cause, thereby the reduction that the trace element that causes is taken in is diseases induced, one of tracing it to its cause is exactly that people's dietary structure is unreasonable, the loss of the too meticulous nutriment that causes of edible processing mode and trace element.Therefore one of focus of Nutritional studies is exactly the meals enhanced products of developing and promoting high nutrition, non-chemically synthesize, be suitable for digesting and assimilating at present, reaches instant edible, absorbs complete, the superior dietetic purpose of quality.
Glossy ganoderma contains multiple physiologically active ingredient as a kind of fungi of dietotherapeutic, and medical value is higher, and is praised highly by China's traditional medicine always.Can supply in a large number mycelium by the liquid deep layer fermenting technology, mycelium can organically combine the trace elements such as zinc, iron, selenium, germanium simultaneously, further improve the health-care effect of tunning, the ganoderma lucidum fruitbody of comparing, be easy to digest and assimilate, production cycle is shorter, and edible quality safety is controlled, and therefore can be used as current a kind of effective technology satisfies people to the demand of ganoderma lucidum product variation and edible health.
Trace element has important physiological function, it is the growth factor that to synthesize voluntarily in the human body, quantitative proportion is not only arranged when coexisting in human body, the more important thing is that they adjusting, balance by shareds such as mutual synergies and are keeping the normal physiological metabolism of human body, excessive metallic element can cause poisoning, suppresses thalli growth.In ganoderma lucidum liquid submerged fermentation process, only has clear and definite mycelium to the different transform modes of different trace elements, by regulating addition, the control conversion ratio, realize that ganoderma lucidum mycelium forms the complex compound part by biofermentation with relevant trace element, by the impact on Ganoderma lucidum mycelium bulk-growth and trophic function of science test and reasonable assessment trace element, adopt mutagenesis acclimatization technology and interpolation trace element to transform lucidum strain, reach and improve the ganoderma lucidum mycelium biomass and strengthen ganoderma lucidum mycelium to the accumulation ability purpose of wholesome trace element.
Existing patent with the Ganoderma lucidum submerged fermentation technical licensing has " preparation method of ganoderma biological activity multivitamin intesifying agent " (Chinese patent grant number CN100379850C), take Ganoderma Lucidum as bio-carrier, at first be the preparation medium, prepare medium with carbon source, nitrogenous source, chiltern element; Next is the medium sterilization that will prepare; The 3rd is to add Liquid Strain of Ganoderma Lucidum in medium; The 4th is that certain hour is cultivated in ventilation under the uniform temperature condition, obtains liquid form product; The 5th be liquid form product is concentrated, dry, be broken and crushed into powder products.Technique of the present invention is simple, and is easy to operate, can be widely used in immunization programs for children power low, children's calcium deficiency, hypoferric anemia; Human female is weak, physiologic anemia; Prevention and the treatment of the osteoporosis that the decline of the elderly's immunity function, endocrinopathy cause; Existing patent with the Ganoderma lucidum submerged fermentation art applications has " a kind of liquid fermentation method that utilizes rare earth element to improve yield of ganoderma lucidum triterpenoid " (Chinese patent application number 201010230701.6), " production method of multielement glossy ganoderma selenium " (Chinese patent application 99108733.X), " method for producing germanium-enriched glossy ganoderma mycelium " (Chinese patent application number 200910011338.6), " ultraviolet ray irradiation improves the method for vitamin D content in the lucid ganoderma calcium fortifier " (Chinese patent application number 201010230330.1), weak point is summarized as: 1. trace element forms single; 2. do not carry out the mutagenesis domestication to having the Rich in Trace Element ability and being suitable for the liquid state fermentation ganoderma strain capable, or induced-mutation technique is single; 3. process for mycelium after the fermentation, particularly dry processing is simple, causes the mycelium solubility poor, and quality reduces, even has affected the activity of mycelium active ingredient.
Summary of the invention
The objective of the invention is to adopt ultraviolet joint Co 60 gamma ray mutagenesis domestication, screening is suitable for the ganoderma strain capable of enrichment various trace elements, through a kind of edible safety of liquid fermentation and culture, be beneficial to the ganoderma lucidum mycelium that is rich in various trace elements of absorption of human body and utilization.
