Problems solved by technology

[0005] It can be seen that the addition of urea-degrading enzymes, or the use of foreign yeast strains that are not native to the scope of protection, directly violates the regulations of GB / T17946-2008, and the rice wine produced cannot be called Shaoxing wine
The use of adsorbent materials to absorb EC in rice wine body is suspected of violating the traditional technology, and will damage the traditional flavor of Shaoxing wine to a certain extent.

Embodiment 1

[0024] 10-15 days before the beginning of winter in the lunar calendar, the water from Baijia Lake in the upper reaches of Jianhu Lake is drawn and stored in the water storage tank. A zeolite aeration plate is arranged for each square decimeter at the bottom of the water storage tank. All the aeration plates are connected to an ozone generator through pipelines. connect. The ventilation rate of the ozone generator is set so that the ozone concentration remains at 0.15-0.25ppm under 1 standard atmospheric pressure; ozone.

[0025] After the introduction of ozone is completed, let the water in the tank stand for 12 hours, and install a filter at the outlet of the tank to ensure that the water is clear. The above-mentioned clarified water is passed through the first filter tank filled with KDF55 with a particle size of 20-50 mesh, and then through the second filter tank filled with ceramsite with a particle size of 2.5-3 cm. The inner diameter of the filter tank is 30cm, the le...

Embodiment 2

[0030] Extract Jianhu water and store it in the water storage tank. An aeration plate made of zeolite is arranged on each square decimeter at the bottom of the water storage tank. All aeration plates are connected to an ozone generator through pipelines. The ventilation rate of the ozone generator is set so that the ozone concentration is maintained at 0.20-0.30 ppm at 1 standard atmospheric pressure. In this embodiment, the time for introducing ozone is 40 minutes, and 1.0 cubic meters of ozone is introduced per cubic meter of water.

[0031] After the introduction of ozone is completed, let the water in the tank stand still for 36 hours, and install filter cotton at the water outlet of the tank to ensure that the water body is clear. The above-mentioned clarified water is passed through a filter tank filled with a particle size of 20-50 mesh KDF55, and then through a filter tank filled with a particle size of 2.5-3cm ceramsite. The inner diameter of the filter tank is 30cm,...

Embodiment 3

[0036] Extract Jianhu water and store it in the water storage tank. An aeration plate made of zeolite is arranged on each square decimeter at the bottom of the water storage tank. All aeration plates are connected to an ozone generator through pipelines. The ventilation rate of the ozone generator is set so that the ozone concentration is maintained at 0.20-0.30 ppm at 1 standard atmospheric pressure. In the present embodiment, the time for introducing ozone is 50 minutes, and 0.5 cubic meters of ozone is introduced per cubic meter of water.

[0037]After the introduction of ozone is completed, let the water in the tank stand for 24 hours, and install filter cotton at the water outlet of the tank to ensure that the water body is clear. The above-mentioned clarified water is passed through a filter tank filled with a particle size of 20-50 mesh KDF55, and then through a filter tank filled with a particle size of 2.5-3cm ceramsite. The inner diameter of the filter tank is 30cm,...

Abstract

The invention belongs to the technical field of food processing and in particular relates to a production method of low-EC (ethyl carbamate) Shaoxing wine. The method comprises the following steps of screening raw material rice, and removing nitrogen, lead and zinc ions from a raw material water source; performing yellow wine brewing on the screened raw material rice in the processed water source by adopting a 'rice feeding' method in a conventional process of Shaowing wine to obtain the low-EC Shaoxing wine. The method is simple and effective, and the content of EC in the Shaoxing wine can be effectively reduced while the flavor of the Shaoxing wine is kept.

Description

technical field [0001] The invention belongs to the technical field of food processing and relates to a production method of Shaoxing wine with low EC content. Background technique [0002] Ethyl carbamate (Ethyl carbamate) is referred to as EC, also known as Urethane, which was listed as a class A2 carcinogen by the International Agency for Research on Cancer in 2007. It may have gene carcinogenic effects and can cause lung tumors, lymphomas, liver cancers, skin cancers, etc. EC in food is mainly produced by the reaction of carbamyl compounds with ethanol. According to the research conclusion published by the Food Safety Center of the Hong Kong Special Administrative Region Government in October 2009, the 39th issue of "Food Safety Focus", the EC content in rice wine is about 140-390 μg / L. Although the EC content in rice wine is lower than the EC standard content of EU fruit brandy (less than 400 μg / L), the EC content in rice wine is still higher than the international sta...
