Let me show you Take half spoon of alkali powder and put it into the wine, stir evenly After half a minute, if the color changes to blue black or black, it can be preliminarily determined as true wine, and the wine with no change in color is fake wine Then, add a spoonful of vinegar to the red wine whose color changes, and the wine that turns blue black when meeting alkali powder will return to the original purplish red color, it can be judged as true wine, otherwise it is still fake wine According to the national standard, the principle of color change is that the real wine must be 100% grape juice, and there must be anthocyanins in the grape juice, and the anthocyanins will react with alkali, and the original purple will become purple black and blue black Therefore, when the wine changes color with alkali, it is true After adding white vinegar, the anthocyanin reacts with acid after reacting with alkali again, which changes back to the original purple, further proving that wine is indeed a real wine with 100% grape juice However, there is no grape juice in the mixed fake wine, and the color is just the pigment mixed out, while the pigment and alkali will not react with alkali noodles and vinegar, so there will be no discoloration reaction Today's small edition of Baibai safety net introduces how to distinguish fake red wine with vinegar If you want to know more about vinegar selection, seasoning and food safety, please continue to pay attention to our website, and hope today's content can help you Editor in charge: sun Dianwei
