Abstract

The invention discloses a preparation method of Chinese chestnut functional fermented food and relates to the field of microbial fermentation and biomedicine. In the invention, monascus and lactic acid bacteria are used as fermentation strains; and after bevel activation culture and liquid enlarge culture, a Chinese chestnut fermentation medium is inoculated with the fermentation strains, and then a functional fermented product rich in polyphenols, lovastatin and monascus pigment is obtained by fermentation. After drying and grinding, the Chinese chestnut fermented product can be directly used as functional food with functions of regulating blood glucose and blood fat, tonifying the kidneys and invigorating the body, improving gastrointestinal functions and the like.

Description

A kind of preparation method of the functional fermented food of Chinese chestnut
Technical field
The invention belongs to fermentable and biomedicine field, be specifically related to a kind of functional fermented food of Chinese chestnut Preparation method and applications.
Background technology
Monascus (Monasucs spp.) is one of China useful fungi being applied to food processing the earliest.About red colouring agent for food, also used as a Chinese medicine Medical value, Ming Dynasty's Li Shizhen (1518-1593 A.D.) describes in Compendium of Material Medica: " red colouring agent for food, also used as a Chinese medicine temperature taste is sweet, nontoxic.Main help digestion, invigorate blood circulation, invigorating the spleen, Dry stomach, controls dysentery, Xia Shuigu." " book on Chinese herbal medicine to roll up four through solution " description: " red colouring agent for food, also used as a Chinese medicine steams with plain rice and affixes one's name to into redness, has same gas with ying blood The reason asked mutually;Can rise blood and invigorating the spleen, spleen is good for, then for its rule liquid of stomach row, stomach is dry.Control dysentery person, there to be the merit helped digestion of invigorating blood circulation Also;Lower water paddy person, temperature reaches the power of liver taste sweet benefit spleen also ... ".Modern medicine study shows to produce in Monascus sweat Multiple secondary metabolite, has the multiple physiological active functionses such as anti-oxidant, reducing blood lipid, norcholesterol, prevention and cure of cardiovascular disease.
Lactic acid bacteria (lactic acid bacteria, LAB) is that a class can utilize fermentable carbohydrate to produce in a large number The common name of the bacterium of lactic acid.Lactic acid bacteria is possible not only to improve nutritive value of food, improves flavour of food products, improves food preservation And added value, and the special physiological of lactic acid bacteria activity and trophic function, the most day by day cause the attention of people.Numerous studies data Showing, lactic acid bacteria can promote growth of animal, regulation composition of gut flora, maintenance microecological balance, thus improves intestines and stomach merit , food digestion rate and biological value can be improved, reduce serum cholesterol, control endotoxin, spoilage organisms growth in suppression enteron aisle, with And improve immunity of organisms etc..
Chinese chestnut (Castanea mollissima Blume) belongs to Fagaceae (Fagceae) Castanea arbor economic plants, have The laudatory title of " kings of thousand fruits ", is one of world-renowned dry fruit.Chinese chestnut property is sweet, and taste is glutinous, nutritious, its medicinal efficacy from Gu to The present praises highly for doctor always, and the SUN Si miao Tang Dynasty thinks that chestnut is that " also, ephrosis preferably eats it to the fruit of kidney." Compendium of Material Medica says plate Chestnut: " controlling and suffer from a deficiency of the kidney, waist pin is unable, outstanding dry with bag Sheng Shengli, eats more than ten every day, and secondary pig kidney congee of eating helps it, for a long time must be strong ".Modern Nutrition analysis shows: the nutritive value of Chinese chestnut exceedes rice, flour and potato class, containing protein 10.7%, fat in its fruit 7.4%, starch 70%.Additionally, Chinese chestnut is possibly together with abundant unrighted acid and vitamin, mineral matter, high blood pressure, hat can be prevented and treated The diseases such as worry, artery sclerosis, sclerotin are thin, are excellent tonic products anti-aging, that promote longevity;Chestnut taste is sweet, warm in nature, enter spleen, stomach, Kidney channel;There is nourishing stomach and spleen, Kidney-invigorating and tendon-reinforcing, effect of promoting blood circulation and hemostasis.But, although Chinese chestnut nutrition and possess certain dietotherapy merit Effect, but should not eat, because Chinese chestnut is nondigestible, easy stagnant gas. more.If able to the physiological function of Monascus and lactic acid bacteria and The nutritive effect of Chinese chestnut organically combines, and makes fermented product contain multiple efficacies components Component, it will to make Chinese chestnut function Property tunning there is the highest edible and medical value.At present, relevant Monascus fermenting and producing monascorubin, red colouring agent for food, also used as a Chinese medicine mycelia The research report of body, MonacolinK and reduction citrinin content etc. is more.But, there is not yet so far and utilize Monascus and breast Acid bacterium mixed fungus fermentation Chinese chestnut preparation has the report of the functional fermented food of Chinese chestnut of multi-efficiency.
Summary of the invention
The invention provides a kind of side utilizing Monascus and lactobacillus mixed fermentation Chinese chestnut to prepare functional fermented food Method.On the one hand Monascus utilize Chinese chestnut rich in starch as culture medium, it is also possible to a large amount of production has hypoglycemic and blood fat, anti- The metabolite Lovastatin of the effect such as atherosclerotic and monascorubin;On the other hand after chestnut starch is fermented by Monascus Producing oligosaccharides and the growth and breeding of glucose promotion lactic acid bacteria, lactic acid bacteria gives the good digestibility of Chinese chestnut fermented product and uniqueness Local flavor.Chinese chestnut Monascus and lactobacillus mixed fermentation product may be used for production and have regulation blood sugar, blood fat, kidney tonifying are healthy and strong and change The functional food of the effects such as kind gastrointestinal function.
