How to buy tips
The festival is thick and short: The number of knots does not affect the quality. When shopping, it is necessary to pick a stubby knot, mature enough, and taste better.
Longer pitches: The longer the spacing between tangles and knots, the higher the maturity of lotus roots and the softer the mouthfeel.
The shape should be full: The lotus root must have a full shape. Do not choose lotus roots with incomplete shapes.
With wet mud: Lotus roots without wet mud are usually treated, and are not resistant to preservation. Lotus roots with wet mud are better preserved and can be placed in a cool place for about 1 week.

How to prevent helium from getting dark
In fact, it is not difficult to keep lotus roots white. Boiled in 100 °C boiling water for 70 seconds can make all the polyphenol oxidase lost, also called the stop polyphenols to the quinone transformation process. However, this method may only be suitable for dishes such as ribs, stewed lotus root, which require soft chewy texture. If you use this method to make cold glutinous rice, black is not dark, but it also loses its crisp taste.
Do not worry, in addition to high temperature treatment, appropriate addition of acidic substances can also bind the hands and feet of polyphenol oxidase. In the production of cold selenium tablets, vinegar is immediately added to hot selenium tablets, which can largely avoid the catalysis of polyphenol oxidase and maintain the white lotus color. In fact, some instant-packaged selenium tablets have added substances such as citric acid that inhibit polyphenol oxidase activity.
Those fresh hawks who bought it could not finish eating in a short time. How can they remain clean? This is not difficult, although polyphenol oxidase has a strong catalytic effect, but the need for oxygen participation, phenolic compounds in lotus root can be oxidized into helium, so isolating oxygen is also a method. Soaking lotus root in water can delay the blackening of lotus root.
