Group physical and chemical index.
The physical and chemical index analytical table of 3 various dose irradiation height white wine of table
Reaction equation 1：
Reaction equation 2：
Reaction equation 3：
White wine its total acid, total ester from table 3 this it appears that after electron beam irradiation, ethyl acetate, lactic acid second
Ester, ethyl hexanoate have different degrees of increase.This is primarily due to white wine and is irradiated by beam radiation, and it is free to generate high energy
Base, to which initiated oxidation is reacted, accelerating reaction makes the process of reaction equation 1,2, and the high spirit total acid after irradiation increases；With
The substantial increase of acid, the balance for advancing reaction equation 3 move right, and total ester is consequently increased in high spirit.With irradiation agent
The increase of amount, the total acid content in high spirit are being continuously increased, but total ester first increases and subtracts afterwards, so irradiation dose is 2.6kGy
When, total ester content is maximum, and 28.8% is improved compared to the control of non-irradiated white wine.When irradiation dose is increased to 3.5kGy, relatively
Non-irradiated white wine improves 17.3%, but for the white wine of 2.6kGy, its total ester is reduced to 11.5% to relative irradiation dosage.This
May be because when irradiation dose is excessive, the ingredient for causing the free radical of water in high spirit is increasingly complex, makes its side reaction
Generation and cause.To sum up, it is to be illuminated white wine total content highest that irradiation dose, which is 2.6KGY, and distilled spirit fragrance is apparent.
By 3 kinds of main esters of the high spirit of various dose electron beam irradiation, irradiated influence is different
The increase of degree, wherein ethyl acetate variation are most apparent, play the effect of the white wine accelerated ageing after electron irradiation.

Best results, taste are coordinated and have aftertaste lingering fragrance.Secondly it is 1.8kGy>3.5kGy>White wine after 0kGy, 3.5kGy radiation treatment
Pungent and rear taste slightly hardship are increased slightly, this is primarily due in white wine H in the increase of aldehyde content and free radical2O2Concentration compared with
Caused by 1.8KGY, 2.6KGY are slightly higher, so strictly to control irradiation dose range in this irradiation technique, electron accelerator is used
Irradiation white wine effectively can artificially control the power of irradiation output electron beam or control the flow velocity of white wine under beam, reach irradiation agent
