Description

Lichee wine that the smell of fruits is very sweet and preparation method thereof
Technical field
The present invention relates to technical field of beverage, and in particular to lichee wine that the smell of fruits is very sweet and preparation method thereof.
Background technology
Lichee is known as " four big fruit of the southern part of the country " together with banana, pineapple, longan.Lichee (Litchi chinensis Sonn. it is) Sapindaceae (Sapindaceae) lichee category (Litchi) aiphyllium, is fruit tree tropical, that subtropical zone is important, China has more than 2000 years cultivation history, culture area and yield to account for about 80% of the world or more, and the main place of production is at me The provinces such as state Guangdong, Fujian.Lichee south native to China, is subtropical fruit tree, and aiphyllium is about 10 meters high.Pericarp has fish-scale Shape protrusion, it is scarlet, it is purplish red.Pulp production translucent congealed fat shape, savory U.S. when fresh.The tender succulence of lichee, aromatic flavour, rich in a variety of Nutritional ingredient needed by human has nourishing and medical value, is known as the treasure of China.It is lichee tastes sweet, acid, warm-natured, enter the heart, Spleen, Liver Channel;Pulp have effects that tonifying spleen and liver, qi-regulating enrich blood, warm in pain, heart tonifying and tranquilizing;Core has qi-regulating, dissipating bind, stops The effect of pain;Hiccup can be stopped, only diarrhea, be the diet good food of intractable hiccup and diarrhea before dawn person, while have cerebrum tonifying body-building, whetted the appetite Beneficial spleen has the effect of promoting appetite.But lichee heat, more foods are easily got angry, and can cause " litchi sickness ", moreover, lichee is intolerant to storage Hide, because " discoloration due to one day, two days and it is fragrant become, three days and taste becomes " characteristic and influencing far transport and commodity value, it is easily brown after adopting Become and rot, it is difficult to preservation and freshness.So carrying out the processing of lichee fresh fruit and developing and using, processed with solving the product currently faced Rate is low, added value is low, fresh keeping time is short, can not open up the series of problems such as lichee market at a specified future date, and lichee is given full play to reach The purpose of economic benefit and social benefit after harvesting.
Litchi pulp is tender, and containing higher sugar point, appropriate organic acid and a variety of amino acid, nutritive value is high, unique flavor. It is existing studies have shown that containing abundant fragrance component, including alcohols, alkene terpene and esters etc. in fresh lichee, alkene terpene total amount At most, 17.31% is accounted for, wherein deodar alkenes content accounts for 6.42%;Followed by alcohols accounts for 16.74%, mainly geraniol, Geraniol is the substance to play a crucial role to lichee characteristic flavor on basis;Esters only have ethyl acetate, content 15.21%, all Content highest in aroma substance, it has smell as strong ether, and clear clever, micro-strip fruity aroma is easily spread, not persistently;Terpene The kind of class compound major part source and fruit is fragrant, its fragrance threshold value is often very low, just will produce in very low concentration Dense fragrance, and all there is typical fruit flavor and flowery odour.Alcohols and ester type compound volatility are less than alkenes, therefore The main component for constituting the pure and fresh head perfume of lichee is alkenes component.Lichee typical case flavor and nutritional ingredient are significantly different from other water Fruit, but it in machining process, the fruity meeting of lichee is all or the overwhelming majority is lost, to seriously affect lichee wine Therefore quality studies the dynamic change that entire lichee makes brewing process fragrance component, understand lichee and make fragrance master in process It wants the type and content of ingredient to change, discloses the changing rule that lichee typical case flavor makes different process operating unit in processing lichee And influence factor, you can establish and retain the lichee of lichee typical case's flavor to greatest extent and make the manufacturing technique method of class product and corresponding Technical parameter, promoted lichee make processing overall technology is horizontal and product competitiveness.

4, result:
5, it analyzes:
Pol, the acidity of Lychee juice itself are not suitable for direct fermentation, therefore are required for adjusting component or sugar before fermentation Sour ratio, Lychee juice alkene terpene substances type and total content after adjusting component obviously increase, and perfume (or spice) is promoted after illustrating adjusting component The volatilization of gas substance, aroma substance volatilization increase, it is meant that loss in the subsequent process can also increase, this is fruit during lichee is made One of loss of aroma reason.And embodiment 3 avoids the reduction of alkenes substance by adding litchi extract solution.
3 aromatic substance of embodiment also increased, and most of aromatic compounds have distinctive armaticity, therefore right The contribution that lichee makes fragrance cannot also be ignored.
With the increase of process, lichee makes alkene terpene substances in fragrance component and falls sharply, and increases with the number of working process, terpene Substance is gradually reduced.With alkene terpene substances on the contrary, alcohols material content and type or in rising trend, content is also begun to Increase.
In fermentation process, Ester is higher with respect to alcohols material content, and ester can generate apparent fragrance.Lichee is made When trial test, almost all of fragrance is generated by esters, alkenes substance.The forming amount of ester depends primarily on yeast strain, And it is influenced by fermentation condition.The type and quantity of ester are different, determine the fragrance and style of wine.Other than the content of ester, The composition of ester and distribution also play a part of gill fungus to the mouthfeel of wine and want.The content of esters not only wants high, more wants harmonious, could assign Lichee makes excellent mouthfeel.
