Description

The production method of natto fermentation pollen
Technical field
Present invention belongs to the preparing technical field of biochemical article, is related to a kind of production method of natto fermentation pollen.
Background technology
Pollen is the Male reproductive cell of plant, similar to the sperm of animal.Though pollen is little, can be multiplied into newly by it Plant, so claim pollen be plant " Source of life ", it has concentrated the elite of whole plant, containing abundant nutrition Composition and medicinal ingredient, reputation is complete cell nutritious element in the world.It not only carries the hereditary information of life, and includes And breed complete nutrients matter necessary to new life, be plant produce a male heir to continue the family line basic, containing abundant cytology level Nutrient content, such as protein, amino acid, vitamin, trace element, organized enzyme, flavone compound, lipid, nucleic acid, rape Element, phytic acid etc., wherein amino acid content and ratio are closest to the amino acid pattern that FAO (Food and Agriculture Organization of the United Nation) (FAO) is recommended, this Extremely rare in wholefood.What pollen was gathered by honeybee is referred to as Bee Pollen, because it is not only pollen, also includes honeybee The special glandular secretion thing added in gatherer process, thus with unique natural health effect and medical treatment and beauty valency Value.
Pollen is the guarantee of honeybee source of nutrition, and royal jelly is that pollen obtains " nutrition elite after honeybee conversion in the body Crystallization ".However, the yield of royal jelly is limited, so how artificial by pollen transformation so as to which nutrition is more enriched simultaneously The nutritive value for being similar to royal jelly is produced, is also always the problem that those skilled in the art endeavour to solve for a long time.Microorganism Fermentation is exactly a large amount of enzymes (ferment) using generation in microorganism growth process, and the technology converted by nutriment is micro- Biofermentation can be turned the foul and rotten into the rare and ethereal, and bland rice, face, transformation of soybean are that wine, vinegar, sauce etc. are delicious and nutrition is easy to The novel substance of absorption.The common wine in living on ordinary days of people, vinegar, sauce, fermented bean curd etc. are all fermented products.Pollen is in honeybee body Royal jelly is converted in the presence of enzyme, conventional people are exactly to combine using different microorganisms, pollen is turned by enzyme needed for producing Turn to " the class emperor slurry " of the effect of similar royal jelly.Be characterized in, 1, vitamin content increase, particularly human body can not oneself synthesis Farnoquinone blood calcium can be converted into bone calcium, prevent and treat senile osteoporosis;2nd, high molecular weight protein degrades to be formed greatly The active peptides of amount, helpful to step-down, hypoglycemic, reducing blood lipid;3rd, Flavone content increases, hypotensive, blood fat, antiviral energy Power strengthens;4th, some peculiar polysaccharide are formed, stimulates immunologic function to strengthen;In addition they can also produce some special enzymes, such as receive Beans kinases, can prevent heart infarction, dredging and softening blood vessel, prevention of cardiovascular disease.Therefore, " the class emperor formed by fermented pollen Health care sage's product that the slurry " Johnson & Johnson that can yet be regarded as is healthy and strong.
The bacterial strain that can be used to ferment is numerous, and wherein bafillus natto is one of current study hotspot.Natto Japan Through there is the history of more than 1000 year, which is made of initially using the fermentation of bacillus subtilis soya bean on the straw of kitchen, is vegetarian diet monk The important foodstuffs source of nutrition of companions, then also gradually comes into vogue in imperial family.Japan has started whole people's food natto within 1996 Upsurge.Japanese government is disposed as special project in its " plan educated by food " special secondary school goalkeeper's natto that carries out, i.e., from little culture children Teenager eats natto.The Japanese whole people ate natto less than 10 years, just became the long-lived big country of first for generally acknowledging in the world.Soya bean Under bacillus natto to ferment effect, in the natto of 100g, just include different amino acid (16g), Aneurine (0.07mg), Verdoflavin (0.56mg), Vitamin B6 (0.24mg), fiber (6.7g) etc., the natto of generation of particularly fermenting Kinases has corroded rock mass, can understand thrombus with oral absorption, for coronary heart disease, the treatment of cerebral thrombus and artery sclerosis.
At present, the domestic health-care natto food that national Bureau of Drugs Supervision has been approved by has 14 kinds, and its function is strengthen immunity With auxiliary reducing blood lipid.Japan, the country such as Korea also have developed multiple products with Nattokinase as primary efficacy in recent years, only The annual marketing volume of the nutriment of US and European and functional food just reaches 500,000,000,000 dollars, and Nattokinase is eaten as feature Quickly growing for product and health products, gathers around and holds out broad prospects.
Although pollen itself is nutritious, often with a small amount of peculiar smell (as fishy smell), part population is not easily accepted by, and Pollen is changed into through honeybee after royal jelly, and nutrition is more comprehensive and is easy to absorb, and whether we artificially can simulate honeybee, will flower Where powder transforms into " class bee milk " through fermentable?The purpose of the present invention is exactly the peculiar smell for eliminating pollen, while by pollen Middle nutrient content is changed into more nutritious to human body and is more easy to the composition that is absorbed by the body.Though human use's fermentable The history of more than one thousand years is so had, but as pollen source is limited, is belonged to and treasures article, the past, never someone was once luxuriously using flower Powder is fermented for raw material.Only bee-keeping scale now, Bee Pollen wide material sources, quantity have guarantee, and people just open successively Begin the research of this respect.And though natto is the food of fashionable Japan, simply just starts within nearly 2 years China is introduced, receive at home Beans are not yet received by most crowds, so pollen and natto are organically combined by not yet someone's consideration so far, Gu Shi At present also still without this kind of product on field.
