Abstract

The invention discloses a method for removing odor and taste of a potassium lactate solution. According to the invention, the odor and taste of the potassium lactate solution are removed by putting columnar activated carbon in a lactic acid solution. In the method, the columnar activated carbon with a special grain size is used as a main raw material for removing the odor and the taste of the potassium lactate solution, and the columnar activated carbon has the characteristics of reasonable pore structure, good absorption property, high mechanical strength, low construction cost and the like, and is easy to repeatedly regenerate. The columnar activated carbon is used so as to treat potassium lactate, so that the bad odor and taste substances in potassium lactate can be removed, treated potassium lactate fundamentally has no metal odor and bitter taste as well as strong and irritant smell, astringent and fermentable flavor.

Description

technical field [0001] A method for removing the odor and taste of potassium lactate solution. Background technique [0002] The potassium lactate solution obtained after the reaction of lactic acid and potassium hydroxide shows bad taste and odor substances such as bitterness. Potassium lactate is mainly used in meat processing, but the disadvantage of most potassium salts is that they cause a bitter taste. Therefore, there is a need for potassium lactate with improved taste and odor properties, usually treated with activated carbon. It is found in production that the potassium lactate solution has an erosive effect on the activated carbon after long-term use, thereby affecting the quality of the potassium lactate solution. The impact of activated carbon with low particle size is particularly serious; The height of the columns reaches several meters, so the structural strength and hardness of the activated carbon are very important. Contents of the invention [0003] Th...
