Black garlic, or Black Garlic, is ordinary garlic that is fermented under specific conditions and is thereby 80 times richer in healthy active compounds.
This special method was developed in the 2000s in Japan. White garlic is fermented for several weeks in a closed environment at temperatures of 60 to 90 degrees Celsius and high humidity (70 to 90%). A natural chemical reaction occurs: the amino acids and sugars in the garlic are converted into browning compounds called melanoidins, which have strong antioxidant activity. This process gives the garlic its black colour, a soft, slightly sticky texture and a very distinctive taste of plum, vanilla, caramel and liquorice.
The typical sulphurous smell of fresh garlic is caused by the odourless volatile substance alliin, which is converted into the strongly smelling compound allicin when the clove is cut or chewed. Fermentation converts these sulphur-containing components of fresh garlic into stable, odourless substances. For this reason, black garlic leaves no unpleasant breath or body odour. It is also much gentler on the stomach.
Benefits of ordinary garlic include well-documented antibiotic, antioxidant, antithrombotic and blood-pressure-lowering effects. Black garlic contains only about half as much water, so its vital and nutrient values and its health effects are higher.
In addition, new valuable compounds are produced during the maturation process that are responsible for many of black garlic's benefits. These include probiotics, which are important for our gut flora and support the immune system, and secondary plant compounds that neutralise free radicals.
Studies show that the content of polyphenols and phenolic compounds in black garlic increases by 3- to 4-fold and the content of flavonoids by 2- to 8-fold compared with white garlic. Sulfur compounds such as S-allylcysteine, which are present in black garlic at concentrations 3 to 6 times higher than in fresh garlic, act as radical scavengers and protect our cells.
Black garlic also contains vitamins A, C, E and B vitamins, calcium, phosphorus, sodium, potassium and magnesium.
The active compounds in black garlic have a positive effect on the cardiovascular system. People from the Mediterranean region, who traditionally eat a lot of garlic, suffer less from cardiovascular disease. Several studies have examined arterial stiffness, systolic blood pressure and pulse wave velocity after several weeks of fermented garlic consumption and reported positive results. Platelet aggregation and thus the formation of blood clots were also impaired.
A meta-analysis evaluating studies on the effectiveness of black garlic concluded that it can help lower the “bad” LDL cholesterol. Furthermore, black garlic alleviates vascular damage and makes blood vessels more elastic.
Recent research has shown that black garlic has a positive effect on certain inflammatory and immune markers and thus on the intact function of the immune system in overweight people.
