Description

A kind of preparation method of the functional fermented food of lotus seeds
Technical field
The invention belongs to fermentable and biomedicine field, be specifically related to the preparation method and applications of the functional fermented food of a kind of lotus seeds.
Background technology
Monascus (MonasucsSpp.) it is one of China useful fungi being applied to food processing the earliest.About the medical value of red colouring agent for food, also used as a Chinese medicine, 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, control 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, with ying blood, the reason that People of the same tastes and habits like to be together;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, invigorate blood circulation the merit helped digestion also to have;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) it is that a class can utilize fermentable carbohydrate to produce the common name of bacterium of a large amount 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 is active and trophic function, the most day by day causes the attention of people.Numerous studies data shows, lactic acid bacteria can promote growth of animal, regulation composition of gut flora, maintenance microecological balance, thus improve gastrointestinal function, improve food digestion rate and biological value, reduce serum cholesterol, control endotoxin, spoilage organisms growth in suppression enteron aisle, and improve immunity of organisms etc..
Lotus seeds be Nymphaeceae Nelumbo (Nelumbo nucifereGaertn) seed of plant, at China, India and Southeast Asian countries lotus seeds as a kind of functional food history of existing thousand of years.In recent years, receive much concern owing to lotus seeds have abundant nutriment and potential medical value.Lotus seeds, rich in flavonoids such as the alkaloids such as liensinine, isoliensinine, neferine, Nuciferine, Pronuciferine, lotusin, methyl-corypalline, demethyl coclaurine and cistus grass glucoside, hyperin, rutins, can be made as raw material and have the clearing heat and detoxicating food preventing and treating the functions such as hypertension, high fat of blood, coronary heart disease, diabetes.If able to the nutritive effect of Monascus and the physiological function of lactic acid bacteria and lotus seeds is organically combined, make fermented product rich in multiple efficacies composition, it will to make the functional tunning of lotus seeds have the highest edible and medical value.At present, the research report about Monascus fermenting and producing monascorubin, Monascus anka Nakazawa et sato filament, MonacolinK and reduction citrinin content etc. is more.But, there is not yet so far and utilize Monascus and the preparation of lactobacillus mixed fermentation lotus seeds to have regulation blood sugar and blood fat, improve gastrointestinal function, improve the report of the functional fermented food of lotus seeds of the multiple physiological effect such as immunity of organisms.
Summary of the invention
The invention provides a kind of method utilizing Monascus and lactobacillus mixed fermentation lotus seeds to prepare functional fermented food.On the one hand Monascus utilize lotus seeds rich in starch as culture medium, it is also possible to a large amount of produce metabolite Lovastatin and the monascorubin with the effect such as reducing blood lipid, antiatherosclerosis;On the other hand producing oligosaccharides and the growth and breeding of glucose promotion lactic acid bacteria after lotus seed starch is fermented by Monascus, lactic acid bacteria gives the good digestibility of lotus seeds fermented product and peculiar flavour.Lotus seeds Monascus and lactobacillus mixed fermentation product may be used for producing and have regulation blood sugar and blood fat, improve gastrointestinal function, improve the functional fermented food of the multi-efficiencies such as immunity of organisms.
