What is the main compound responsible for the flavor profile of horseradish?
The main compound responsible for the flavor profile of horseradish is allyl isothiocyanate, a volatile oil that is released when the plant’s cells are damaged. This compound is a result of the enzymatic breakdown of glucosinolates, which are sulfur-containing compounds found in the plant’s cells. When horseradish is grated or crushed, the enzyme myrosinase comes into contact with the glucosinolates, breaking them down into allyl isothiocyanate and other compounds.
The unique flavor and pungency of horseradish are due to the properties of allyl isothiocyanate. This compound is highly volatile, which means it evaporates quickly and binds to the olfactory receptors in the nose, producing a pungent and irritating sensation. The intensity of the flavor and heat of horseradish can vary depending on factors such as the freshness of the plant, the amount of damage to the cells, and the individual’s sensitivity to the compound. Overall, the unique combination of allyl isothiocyanate and other compounds in horseradish gives it a distinctive flavor profile that is both pungent and aromatic.
How does the flavor profile of horseradish change when it is cooked or heated?
When horseradish is cooked or heated, its flavor profile undergoes significant changes. The heat breaks down the volatile compounds, including allyl isothiocyanate, which are responsible for the pungency and flavor of the plant. As a result, cooked horseradish tends to be milder and less pungent than raw horseradish. The heat also breaks down the enzymes that are responsible for the breakdown of glucosinolates, which means that the formation of new volatile compounds is slowed down.
The changes in the flavor profile of horseradish when it is cooked or heated can be desirable in certain dishes, where a milder flavor is preferred. For example, cooked horseradish can be used as a flavoring agent in sauces and soups, where its pungency is not desired.
