Production method of low-sugar low-alcohol mulberry wine
Technical Field
The invention belongs to the technical field of wine brewing, relates to a mulberry wine brewing technology, and particularly relates to a production method of low-sugar low-alcohol mulberry wine.
Background
Mulberry, also known as mulberry, jujube, mulberry kernel, etc., is a fruit of mulberry belonging to the genus morus of the family moraceae. The mulberry has the advantages of moderate sour and sweet taste, unique flavor and rich nutrition, is rich in anthocyanin, polyphenol, sugar, amino acid, multiple vitamins, trace mineral elements and the like, and has various health-care functions of nourishing yin, enriching blood and the like. Because the mulberry has the characteristics of natural growth and no pollution due to the special growth environment of the mulberry, the mulberry is also known as folk cherry tomato and fruit jelly. The mulberry is considered by the traditional Chinese medicine to be sweet in taste and cold in nature, has the effects of strengthening body and building body, such as benefiting five internal organs and joints, promoting blood circulation, nourishing yin and blood, calming mind, reducing blood pressure and quenching thirst, inducing diuresis to reduce edema, nourishing liver and kidney, promoting fluid production and improving eyesight, nourishing blood and dispelling wind, blackening hair and improving eyesight, and the like, and is praised as the best health-care fruit product in twenty-first century by the medical community.
The mulberry wine is a fruit wine product which is mellow and fragrant in vinosity and clear and transparent in wine body and is prepared by taking fresh mulberries and mulberry juice as raw materials, converting fermentable sugar in fruits into products such as alcohol and the like through alcohol fermentation by using saccharomycetes and carrying out an ageing process.
The mulberry fruit wine which is natural, nutritious and healthy in one day is brewed by taking the mulberry as a raw material and applying the modern brewing technology, so that the mulberry fruit wine which is difficult to store can be fully utilized, the wine varieties can be enriched, and the fruit wine market is prosperous.
Because the mulberry pulp is juicy and easy to rot, the mulberry pulp mildews 12 to 18 hours after being picked at normal temperature, and the long-distance transportation, storage and fresh keeping are difficult. In recent years, the planting area of the mulberries is increased, the yield of the mulberries is rapidly increased, but the storage and preservation problems of the mulberries cannot be well solved, and in addition, the mulberries are concentrated on the market in 4-5 months, the sales volume of fresh mulberries is limited, so that the mulberries are in a state of self-generation and self-extinction and cannot be developed and utilized, and huge waste and loss of resources are caused.
The low-energy beverage has low calorie, fat content, sugar content, etc., has certain effect of preventing obesity and some chronic diseases, and is suitable for sub-health people. One of the reasons for sub-health is that high-energy food is always eaten due to usual eating habits, and especially many special people (such as the old, children, patients or people with high physical energy consumption) eat more nutrition to cause sub-health problems such as obesity and the like.
Therefore, the mulberry is comprehensively processed by using modern food processing technology except local and nearby fresh selling, the mulberry is brewed to obtain mulberry raw wine, the mulberry raw wine is distilled to obtain mulberry distilled wine, and the dealcoholized mulberry wine left after distillation is fully utilized to process to obtain the low-energy mulberry alcoholic beverage, namely the low-sugar and low-alcohol mulberry wine, so that the digestion and utilization of mulberry resources are effectively promoted, the product types and consumption modes of the mulberry are enriched, the additional value of the mulberry is increased, and the economic benefit of the mulberry industry is increased.

fermentation circulation: activating 300mg/L yeast with 10 times of 39 deg.C 5% sugar water for 28 min; after activation, pumping into a fermentation tank by a wine pump, and performing closed circulation for 30 min; after inoculation, continuously controlling the temperature to be 20 ℃ and fermenting for 12 days; in the fermentation process, the closed circulation is carried out for 2 times every day, and if the peculiar smell is found in the identification, the open oxygen circulation is carried out; and detecting physical and chemical indexes of the fermented mash, namely indexes of soluble solid TSS, pH, total acid and volatile acid every day;
③ transferring the pot: detecting total sugar at later stage of fermentation, pouring into a tank when the sugar content is equal to 4.36g/L, clarifying at low temperature of 2 deg.C, and removing bottom residue after 3 days to obtain Mori fructus wine base;
(4) and (3) distillation: carrying out reduced pressure secondary distillation on the raw wine obtained in the step (3), wherein the reduced pressure distillation conditions comprise the distillation temperature of 64 ℃, the distillation temperature of 40 ℃ and the vacuum degree of-80 kPa; removing the foreshot and the feints by primary distillation, and taking 0.5-85% of distillate per volume to obtain 37% vol primary distilled liquor; distilling the primary distilled liquor under reduced pressure again to remove wine body and wine tail, and collecting 1.0-80% of distillate per volume to obtain 58% vol mulberry distilled liquor;
(5) soaking and ageing: putting the mulberry distilled liquor obtained in the step (4) into a stainless steel wine tank; collecting mulberry which is eliminated every year in a mulberry planting base, cutting mulberry roots, cleaning, peeling off root barks, cleaning and sterilizing, cutting into pieces, drying in the sun, and baking at 200 ℃ for 30min to obtain yellow-brown mulberry root slices; adding 6g/L of mulberry root slices into the mulberry distilled liquor for soaking, and storing and ageing for 6 months to obtain mulberry root slice brandy;
(6) and (3) distillation: carrying out reduced pressure distillation on the reduced pressure secondary distillation residual liquid obtained in the step (4), wherein the reduced pressure distillation conditions are that the distillation temperature is 60 ℃, the distillation temperature is 30 ℃ and the vacuum degree is-85 kPa; distilling under reduced pressure until the volume of the distilled alcohol is 3%, stopping distilling, and leaving dealcoholized mulberry wine;
(7) and (3) filtering: clarifying the dealcoholized mulberry wine obtained in the step (6) at a low temperature of 0 ℃, and filtering the clarified wine by using a 0.45-micrometer membrane filter after 3 days of clarification to obtain the low-alcohol mulberry wine;
(8) blending: adding stevioside 0.30g/L, momordica grosvenori glycoside 0.20g/L and potassium metabisulfite 300mg/L into the low-alcohol mulberry wine obtained in the step (7); the adding method comprises weighing stevioside and mogroside, dissolving with pure water, grinding with colloid mill, and adding into low alcohol mulberry wine; mixing, and filtering with 0.22 μm membrane filter to obtain low-sugar and low-alcohol Mori fructus wine.
