Aged Allium sativum Bulb Source & Identity
The botanical entity is Allium sativum L., the cultivated garlic of the onion family. The part used is the whole bulb, held for weeks under controlled heat and humidity until the cloves turn soft, dark and sweet. Leaves, scapes, sprouts and roots are not part of this black garlic extract. The darkening is mainly Maillard browning during the heated aging, and the result is still the same species.
Aging changes the chemistry sharply. The alliin that gives raw garlic its allicin pungency falls steeply within the first days of aging, while sugars such as fructose build up, most likely from the breakdown of the bulb’s fructan reserve, so the cloves turn sweet, balsamic and mild. With little alliin left, crushing aged cloves no longer releases the sharp odor of raw garlic. That makes black garlic extract a different ingredient from ordinary garlic extract in flavor and in smell.
