Why to add potassium sorbate to wine

Introduction: wine is a very sweet drink, it is said that wine contains potassium sorbate, so why does wine add potassium sorbate? Xiaobian will introduce you in this article Wine is a very popular drink in people's daily life Many people don't know how to make wine very well Then why does wine add potassium sorbate? I'd like to introduce it to you In the production of sweet wine, sorbic acid is often used as a preservative The antibacterial effect of sorbic acid will play a greater role only under the synergistic effect of sulfur dioxide Sorbic acid is allowed to be used in the national standard, but the maximum limit of the standard should be paid attention to in the use process, and should not exceed the standard At the same time, we should pay attention to the relationship between sorbic acid and sulfur dioxide, alcohol, so as to give full play to the anti-corrosion effect of sorbic acid Sorbic acid is an unsaturated fatty acid, non-toxic, can be fully absorbed by the human body It has a special anti yeast effect, is a stable fungal inhibitor; it can inhibit the reproduction of wine yeast, and has a higher inhibition efficiency when isolated from the air; it can inhibit the sugar fermentation ability of yeast without killing them According to the national standard gb15037-2006 wine, the maximum allowable quantity is 200mg / L all levels of inspection institutions can detect the existence of sorbic acid and determine its added quantity However, it should be noted that some countries do not allow the import of wine treated with sorbic acid, so it is necessary to pay attention to and understand clearly when producing export products The anti yeast ability of sorbic acid will be greatly enhanced due to the presence of ethanol, but the solubility of sorbic acid is relatively small In the actual production process, we often encounter the use of potassium sorbate Now, according to the standard dosage of sorbic acid, the author converts it into the dosage of potassium sorbate, which will be picked up in the Portuguese and Chinese wine Journal: mailing code 23, article source: cnwinenews.com China wine industry wind vane wine industry news network-189 The local post office can subscribe to the following table of recommended dosage of sorbic acid or potassium sorbate after grape wine has been sterilized and filtered, according to the different requirements of alcohol, for reference of peers Please note that sorbic acid has no antibacterial effect no matter how much dose is used Although it can avoid the re fermentation of sweet wine, it can not prevent the acetic acid bacteria pollution of wine and the lactic acid bacteria pollution of wine When sorbic acid disappears, the risk of bacterial contamination increases, and wine has an unpleasant smell, similar to that of Geranium oil, because ethylene glycol has been produced Only in the presence of certain ethanol concentration and sulfur dioxide can sorbic acid show satisfactory results It can strengthen the effect of the latter, but it can never replace them The solubility of sorbic acid in water is not very large, and its more soluble form is potassium sorbate The potassium sorbate solution of 270g / L contains 200g / L sorbic acid Due to the low solubility of sorbic acid, it is necessary to be careful when adding it to wine Add it slowly, stir it strongly, and mix it well with circulation pump In the following conditions, sorbic acid can effectively inhibit the activation of yeast in wine: 1 According to the alcohol content and acidity of the wine, use enough 2 The processed wine has been carefully clarified and effectively sterilized and filtered 3 Mix with wine quickly and completely 4 After treatment, the content of free sulfur dioxide in wine is generally 60mg / l-80mg / L, which is enough to prevent oxidation and bacterial growth Food additives have almost become an indispensable problem in the process of food production It's better to use a food safety tester to test them after the completion of production Learning more about food additives can bring benefits to people's diet in the future Among them, what's the role of potassium sorbate?
