Is horseradish an acid or base?

Horseradish is neither an acid nor a base; it is a root vegetable that contains compounds like sinigrin, which gives it its characteristic sharp flavor. When grated or ground, horseradish releases volatile oils that can create a pungent, spicy sensation, but it does not fit into the categories of acid or base in a chemical sense. Its pH level is typically neutral to slightly acidic.
