The differences between horseradish and mustard are: different definitions, different tastes, different places of origin and time of appearance, and different initial functions.

1, different definitions:

Most of the cheaper "green mustard" on the market are made of horseradish. It belongs to the genus Raphanus in Cruciferae. However, the roots of wasabi are pale yellow and white, and after adding green pigment, it becomes what it looks like in the market. The English name of horseradish is horsebrain, which literally translates as horseradish.

In the traditional sense, mustard actually refers to a condiment made by grinding mustard seeds. It is one of the most popular and oldest spices in the world.

2. Different tastes:

Horseradish contains pungent isothiocyanate compound, which has bactericidal effect.

The whole mustard seed itself is not spicy. After the mustard seed is crushed and added with water, the glucosinolates and glucosinolates contained in it will be hydrolyzed to produce spicy isothiocyanates.

3. The origin, appearance time and initial function are different:

Horseradish originated in Central Europe and was originally used as a medicinal plant to treat cough, rheumatism and other diseases. Mustard seeds appeared in the Stone Age. In ancient Europe, mustard seed was generally regarded as medicine rather than food, which was used to treat a series of diseases such as toothache.

Extended data:

Wasabi can be planted in spring and autumn, but mainly in spring. The best planting time is from late March to early April. According to the plant spacing of 30-33cm and the depth of15-20cm, holes are punched on the ridge tops. The hole must be inserted at an angle of about 45 degrees to the ground. Then insert the head of the seed root upward into the hole, and do not plant it upside down. After planting, cover the soil for 3~5.

After planting, the ridge top is leveled and thinned, and then herbicide (acetochlor) is sprayed and covered with plastic film. When laminating, be sure to tighten, compact and press around to prevent the wind from blowing. After covering, the hole of each kind of wasabi will be pierced with a 3-5cm round hole, and then the hole will be covered tightly with fine wet soil, with a thickness of 2cm, which is beneficial to lead the seedlings out of the film and prevent the leaves from burning out.
