Background technology
Existing yellow rice wine is to be main raw material with glutinous rice, wheat, water, through soaking rice, steamed rice, diastatic fermentation, secondary fermentation, squeeze and filter, fry in shallow oil wine, store, blending and form, its ethanol content is general 〉=15% (v/v), total reducing sugar is 15.0~100.0g/l, for a long time, yellow rice wine is subjected to human consumer's favor always with its traditional technology and mellow local flavor.Along with the transformation of fast development of society and consumption idea, need low novel taste yellow rice wine of maintaining normal supply during the slack season refreshing and tool good nutrition value to satisfy the needs of different hierarchies of consumption.
The exploitation of existing low-alcohol rice wine mainly contains following three types:
The one, by the dilution of former wine and to add some nutritive elements such as honey, matrimony vine, longan, VITAMIN formulated.The advantage of this technology is less investment, and is easy and simple to handle, but technology content is not high, is prone to the homogeneity product.
The 2nd, utilize the barms of zymin and low ethanol production, form by the fermentation brew.The advantage of this technology is brew to go out the low alcohol product, but owing to adopted the genetic modification technology, the local flavor of being made wine is unsatisfactory, and factory building, equipment, peopleware are also had higher requirements.
The 3rd, form through the Secondary Fermentation brew with oligose and old shaohsing wine by stream in the secondary fermentation process of existing yellow wine production technology.The advantage of this technology is to go out the low alcohol product by the fermentation brew, but comparatively difficult to the product of brew ethanol content below 10% (v/v), and operation is also comparatively complicated.
Summary of the invention
The object of the present invention is to provide a kind of formulating of recipe reasonable, technology advanced person, ethanol content is lower, has the working method of the low-degree nutrient yellow rice wine of good nutrition value.
The present invention is the working method of low-degree nutrient yellow rice wine, it is characterized in that being undertaken by following technical process:
Yellow rice wine base wine → low-temperature evaporation → concentrated solution → blend → freezing → coarse filtration → membrane filtration → can → finished product; Also add stachyose in blending operation, its add-on is 0.01~20% of a yellow rice wine base wine weight percent.
The add-on of described stachyose can be preferably 0.1~5% of yellow rice wine base wine weight percent.
Described blending in the operation also can add dextrinosan, and its add-on is 1~20% of a yellow rice wine base wine weight percent.
Described blending in the operation also can add Folium Bambosae extract, and its add-on is 0.1~5.0% of a yellow rice wine base wine weight percent.Described Folium Bambosae extract can be extract or other Folium Bambosae extract of Herba Lophatheri.
Studies confirm that, stachyose is a kind of superpower bifidus factor, only need drink 0.5~3 gram every day, can make probioticss such as the interior bifidus bacillus of human gastrointestinal tract, lactobacillus obtain extremely significantly breeding, thereby improve the human body alimentary canal environment rapidly, the microecosystem regulation balance; In addition, stachyose has the effect of removing vivotoxin, and to alleviating burden of liver, recovering liver function has certain effect, but the part alleviation of alcohol is to the pressure of liver; And stachyose can effectively promote trace elements absorbed abundant in the wine, makes wine liquid have healthy nutritive value preferably.
The dextrinosan calorific value is low, be difficult to by human consumption, but sweet taste is mellow and full soft, and sugariness is low, and mouthfeel is good, has the water-soluble dietary fibre function.Do not utilized, do not become so can not cause the tooth dental caries by oral microorganism.Long-term edible dextrinosan can produce indirect physiological effect, comprises and recovers the proper intestinal microflora of little ecologic disturbance person, keeps the intestinal function regular event; Suppress the growth of pathogenic bacteria and spoilage organism, thereby reduce poisonous, objectionable impurities, improve constipation, the protection liver, blood fat reducing strengthens the absorbing power to mineral substance such as calcium, iron.
Come from the Folium Bambosae extract of Herba Lophatheri, major ingredient is a Folium Bambosae flavone, and its characteristic component is Lutonaretin, Orientin, Saponaretin, Vitexina.It is introduced, Folium Bambosae flavone not only has good Green Tea Extract and anti-oxidant activity, reducing blood-fat, blood cholesterol, antioxygenation are also fairly obvious, also has the premium properties of removing active oxygen radical, can improve the resistibility of human body to poor environment and disease, of paramount importance is not contain any objectionable constituent and antinutritional factor in the product, and, side effect nontoxic to human body have great security.
The present invention compared with prior art has following outstanding advantage and positively effect:
1, technological development ethanol contents such as integrated use brewing yellow rice wine, low-temperature evaporation, freezing and filtering, membrane sepn are lower than the trophic function yellow rice wine of 10% (v/v), have captured the technical barrier of low-alcohol rice wine " tasteless ", have solved the anti-cold stability of yellow rice wine.
2, by scientific and reasonable formulating of recipe combination, with superpower bifidus factor stachyose and dextrinosan, Folium Bambosae extract good health care effect and yellow rice wine nutrition is organic combines together, increase the nutrition of yellow rice wine, innovated the local flavor of yellow rice wine, enriched the intension of yellow rice wine product.
3, forming low-degree nutrient yellow rice wine by working method brew of the present invention tastes through several national yellow rice wine judging panels, think that product color is orange, limpid transparent glossy, aroma is quiet and tastefully laid out, fragrant, and mouthfeel is light refreshing, easypro suitable, does not have the hardship of general yellow rice wine, puckery, pungent, inlet and suitable, superpower bifidus factor stachyose and Folium Bambosae flavone contained in the unique flavor, particularly wine have the good health care effect, meet the consumption concept that the modern pursues nutrient health.
