A kind of making method of gasified wine of lichee
One, technical field:
The present invention relates to a kind of making method of drinks, especially relate to a kind of making method of gasified wine of lichee.
Two, background technology:
Lichee (Litchi chinensis Sonn.) is that Sapindaceae (Sapindaceae) lichee belongs to (Litchi) aiphyllium, the torrid zone, the important fruit tree in subtropics, there is the cultivation history in more than 2000 year in China, culture area and output account for more than 80% of the world, and its main place of production is in provinces such as China Guangdong, Fujian.The tender succulence of lichee, aromatic flavour, be rich in the nutritive ingredient of multiple needed by human, have nourishing and pharmaceutical use, be described as the treasure of China.
Litchi pulp contains a large amount of sugars, vitamins C, phosphorus, calcium and a small amount of protein, fat, iron, vitamins B etc., has a sweet taste good to eat, and be rare excellent tonic product.System analyzes according to central Institutes of Health Research trophology, the per 100 g edible portion water content of lichee 84 g, carbohydrate 14 g, albumin 0.02 mg, riboflavin 0.04 mg, nicotinic acid be mg, xitix 36 mg O.7, contain in addition robust fibre, organic acid, amino acid, Hu trailing plants I-element and the mineral elements such as Zn, Mg.
But lichee affects fortune far away and commodity value because of the characteristic of " look on the one becomes, two days and fragrant the change, three days and flavor become ", and very easily brown stain and rotting is difficult to preservation and freshness after adopting.So carry out lichee fresh fruit processing and development and use, solve that the current product working modulus that faces is low, added value is low, fresh keeping time is short, can't open up the series of problems in lichee at a specified future date market, economic benefit and social benefit after giving full play to lichee and gathering.
Light sparkling wine is a kind of drinks that is popular on the world market, and year consumption is very large, and light sparkling wine normally adopts tame berry fermented soy to form.Traditional light sparkling wine raw material mainly is to carry out Secondary Fermentation with grape juice to form.Do not brewage light sparkling wine with lichee as raw material, and there are a lot of problems in Secondary Fermentation, for example: the production cycle is long, and production process is numerous and diverse, and cost is high, poor quality's control etc.These problems have been brought certain difficulty to kind and the production of light sparkling wine.
Three, summary of the invention:
The present invention provides a kind of making method of gasified wine of lichee in order to solve the weak point in the above-mentioned background technology, and the gasified wine of lichee of making has in this way kept aroma characteristic and the nutritive ingredient of litchi fruits itself.
For achieving the above object, the technical solution used in the present invention is: a kind of making method of gasified wine of lichee comprises following operation steps:
(1) gathers the lichee fresh fruit as raw material; (2) shell, stoning; (3) press extracting juice, add sulfurous gas; (4) clarification; (5) zymamsis; (6) turn tank; (7) fermentation stops; (8) refrigeration ageing; (9) press filtration, the can such as.
The described lichee fresh fruit of gathering is that (when the sugar content of fruit rises to stationary value) manually gathers when the raw material ripening degree reaches best ripening degree as raw material.
The described sulfurous gas that after pressing extracting juice, adds 50mg/L.
Described in the juice clarification process, in fruit juice, add wilkinite, the 500mg/L of 1g/L PVPP,, in 0 ℃ of environment, leave standstill 24 hours after, separate clear juice.
Described in alcoholic fermentation process, add the 0.2g/L yeast, temperature is controlled at 15~20 ℃.
Described when changing sealed can over to, change sealed fermenting tank relaying supervention ferment when treating the residual sugar amount to 24g/L over to, in the fermenting process, the observation pressure carbon dioxide changes, when pressure reaches 0.6 MPa, show that zymamsis finishes, then change over to and stop fermentation in-3~0 ℃ of environment.
Described refrigeration ageing: 0 ℃-4 ℃ approximately 6 months lower ageing times.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
The present invention adopts the lichee fresh fruit as the raw material of light sparkling wine first, the technique that the present invention adopts and processing parameter are so that the finished product of making has kept the aroma characteristic of litchi fruits itself, preserve its natural value, during the fermentation, after residual sugar arrives certain numerical value, turned tank, carry out sealed fermenting, the change fermenting twice is one time fermentation, has simplified production process, has shortened the production cycle, reduce cost, improved the quality of wine.Do not add the chemical substances such as any synthetic food color, spices and sanitas in the production process.Wine body of the present invention limpid transparent, that the litchi spiciness is strongly fragrant, clean taste relaxes is suitable, the due pleasant style of tool gasified wine of lichee.
Four, description of drawings:
Fig. 1 is process flow sheet of the present invention.
Five, embodiment:
The present invention be with litchi fruits shell, stoning, squeezing, clear juice zymamsis by keeping the gas in fermentation later stage, obtains gasified wine of lichee.The implementation step is as follows:
(1) adopt first the lichee fresh fruit as the raw material of light sparkling wine.(when the sugar content of fruit rises to stationary value) manually gathers when raw material reaches best ripening degree.
(2) cooling: by deepfreeze, make temperature reach 2 ℃ grape fruit.
(3) shell, stoning: remove fruit shell and centronucleus, note not remaining in the pulp.
(4) press extracting juice: during squeezing, the control crushing juice rate adds sulfurous gas 50mg/L, to prevent the fruit juice oxidation 50% after the squeezing.
(5) clarification: in fruit juice, add the wilkinite of 1g/L and the PVPP of 500mg/L, in 0 ℃ of environment, leave standstill 24 hours after, separate clear juice.
(6) zymamsis: the yeast that adds 0.2g/L ferments, and temperature is controlled at 15~20 ℃.
(7) change sealed can over to: change sealed fermenting tank relaying supervention ferment when treating the residual sugar amount to 24g/L over to, in the fermenting process, observe pressure carbon dioxide and change, when pressure reaches 0.6 MPa, show that zymamsis finishes, then change over to and stop fermentation in-3~0 ℃ of environment.
(8) refrigeration ageing: 0 ℃-4 ℃ approximately 6 months lower ageing times.
(9) filtration, can: under-3~0 ℃, filter with canned.
