Embodiment 1
[0020] Example 1 Preparation of freeze-dried powder of protective agent. The freeze-dried SOD powder was uniformly mixed with the aqueous solution of protective agent at 0°C-4°C. The amount of protective agent was 1 to 7% by weight, and then made into freeze-dried powder, protective agent Is lactose, galactose, sucrose, trehalose, arabinose, mannitol, dextrose, polysucrose, amino acid, ascorbic acid, tocopherol, lipoic acid, glutathione, vitamin E, cyclodextrin, or n species (3≥n≥1), SOD activity: 100U / ml to 200U / ml, lyophilized into a protective agent freeze-dried powder at a temperature of -20℃ to -5℃. Under the temperature of -20℃ to 10℃, add the protective agent and freeze-dried powder to the liquor (ethanol) with a degree of 20°(%) to 50°(%), the added amount to ensure the activity of the wine: 10U / ml To 20U / ml. Then it is allowed to stand, and the wine is filtered into a clear finished wine with a 200 to 500 mesh filter at an ambient temperature of 5°C to 20°C.
Embodiment 2
[0022] Prepare the freeze-dried powder of the protective agent. The SOD freeze-dried powder is uniformly mixed with the aqueous solution of the protective agent at 0°C-4°C. The amount of the protective agent is 1 to 7% by weight, and then manufactured into a freeze-dried powder. The protective agent is lactose, Trehalose, amino acids (glycine Gly, aminolevulinic acid Ala), ascorbic acid, vitamin E. Any one or n species of (3≥n≥1), SOD activity: 100U / ml to 200U / ml, lyophilized into protective agent freeze-dried powder at a temperature of -20℃ to -5℃. At the temperature of -20℃ to 10℃, add the protective agent freeze-dried powder to liquor (ethanol) with a degree of 20°(%) to 50°(%), and the amount of addition to ensure the activity of the wine: 10U / ml to 20U / ml. Then it is allowed to stand, and at an ambient temperature of 5°C to 20°C, it is filtered into a clear finished wine with a filter screen of 200 to 500 mesh.
Embodiment 3
[0024] Prepare the freeze-dried powder of the protective agent. The SOD freeze-dried powder is uniformly mixed with the aqueous solution of the protective agent at 0°C-4°C. The amount of the protective agent is 1 to 7% by weight, and then manufactured into a freeze-dried powder. The protective agent is lactose, Trehalose, amino acids (glycine Gly, aminolevulinic acid Ala), ascorbic acid, vitamin E. Any one or n species of (3≥n≥1), SOD activity: 100U / ml to 200U / ml, lyophilized into protective agent freeze-dried powder at a temperature of -20℃ to -5℃. Under the condition of temperature -20℃ to 10℃, add the freeze-dried powder of protectant into white wine (ethanol) with a degree of 35°(%) to 45°(%), the added amount to ensure the activity of the wine: 10U / ml To 20U / ml. Then it is allowed to stand, and the wine is filtered into a clear finished wine with a 200 to 500 mesh filter at an ambient temperature of 5°C to 20°C.
