8 health benefits of black garlic
Black garlic differs nutritionally from ordinary garlic and provides various distinct health benefits.

Raw garlic has a pungent flavor and is a staple in day-to-day cooking. The regular white raw garlic turns into black garlic when it is fermented under controlled high temperatures and humidity.

Black garlic is more nutritious than white garlic and provides various health benefits. Despite its health benefits, black garlic is largely underused.

What is black garlic?

The use of black garlic dates to ancient Egypt and it has been used in traditional medicine in India and China. Unpeeled white garlic bulbs are aged for about 40 days in high heat and humidity, resulting in a black bulb. This method of cooking garlic has been used in other nations for centuries and has recently gained popularity in the West.

  • Some of the chemicals in ordinary garlic break down because of this, notably those that give garlic its spicy, pungent flavor (particularly allicin).
  • When these chemicals degrade over time, they give a savory and sweet flavor to the garlic.
  • The heating method reduces allicin concentration but enhances the total antioxidant content of garlic.
  • This reduces gastrointestinal discomfort, which may occur from regular garlic.

Black garlic differs nutritionally from ordinary garlic and provides various distinct health benefits, so it is commonly used in high-end cooking applications. You do not usually find black garlic as a common component because it is both difficult and expensive to produce.

Black garlic is consumed alone, pounded into a powder, infused in oil, added to vegetable meals, and chopped into sauces or glazes. It has a milder flavor than white garlic.
