Fermented Black Garlic
Allium sativum L.
Garlic is belonging to the Alliaceae family, which is a frequently used ingredient in gastronomy. Black garlic is emerging as one of the most well-known functional food in the market. Black garlic (BG) is the garlic that has been fermented at a high temperature for 60 to 90 days, under high humidity (80-90%) without any additional treatment. During the heat process, the garlic turns black or dark due to Maillard reaction. After the process, the garlic will gives a sweet taste and alters their consistency to chewy and jelly-like. The duration of fermentation varies depending on cultures, manufacturers, and purposes. Due to reduced content of allicin, black garlic does not release a strong off-flavor.
Black Garlic is known to contain much more functional compounds than fresh garlic. Black garlic become one of the prominent products in functional food market and nutraceuticals with a remarkable growth of consumption demand due to its abundant amount of bioactive compounds and its health benefits.

|In vivo animal studies|
|Subject||3 week-old db/db mice|
|Group||(1) AIN-93G diet
(2) 5% dried-garlic diet
(3) 5% aged black garlic diet
|Dosage||5% w/w in diet|
|Parameters analyzed||(1)hepatic levels of lipid peroxides
(2)activities of antioxidant enzymes
|Outcomes||(1) Consumption of aged black garlic significantly decreased hepatic thiobarbituric acid reactive substances (TBARS) level than control group (p<0.05).
(2)Results show that aged black garlic exerts stronger antioxidant activity than garlic in vitro and in vivoFigure 1: Effect of garlic and aged black garlic on the levels of hepatic TBARS of db/db mice.
*TBARS = thiobarbituric acid reactive substances
(Lower TBARS lower rate of lipid peroxidation (cell damage))Figure 2: Effect of garlic and aged black garlic on the hepatic activities (a) SOD, (b) catalase, and (c) GSH-Px of db/db mice.
|Funtions||As prolonged hyperglycemia of diabetes induces overproduction of ROS and free radicals that trigger diabetic complications, the high antioxidant effects of black garlic may be useful in preventing diabetic complications.|
|In vitro and in vivo studies
|Subject||SGC-7901 human gastric cancer cells
Kunming mice (bearing murine foregastric cancer)
(2) Aged black garlic extract-treated cells/mice
|Duration||In vitro = 48 hours 7
In vivo = 2 weeks
|Dosage||In vitro = 0-100 mg/mL
In vivo = 0, 200, 400 and 800 mg/kg (intraperitoneally)
|Parameters analyzed||In vitro = apoptosis analysis In vivo = tumour growth inhibition|
|Outcomes||-Extract of black garlic has inhibited proliferation of gastric cancer cells and triggered apoptosis of cancer cells.
-In tumor-bearing mice, significant antitumor effects of aged black garlic extract were observedFigure 1: Effect of aged black garlic extract on the proliferation and apoptosis of SGC-7901 cells in vitro.

|Functions||Black garlic extracts may possess significant anticancer actions.|
|In vivo lab experiment|
|Subject||Sprague-Dawley rats aged 4 weeks (n = 32)|
|Group||(1) Normal diet (NF)
(2) High fat diet (HF)
(3) High fat diet + 0.5% black garlic extract (HFBG0.5)
(4) High fat diet + 1.5% black garlic extract (HFBG1.5)
|Dosage||0.5% (w/w) or 1.5% (w/w) black garlic extract|
|Parameters analyzed||In vitro = apoptosis analysis In vivo = tumour growth inhibitionBody weights and blood biochemical levels (lipid)|
|Outcomes||-Significant differences were observed in the final weights between the 1.5% black garlic extract and high fat diet groups.
-Intake of 1.5% black garlic extract showed more distinct effect in decreasing the kidney and epididymal fat in high-fat models.
-Black garlic extract is observed to lower the plasma level of total lipid, total cholesterol, and triglyceride; and also increases the level of high-density lipoprotein cholesterol (HDL) – the good cholesterol in rats.

|Functions||Black garlic is known to have prominent lipid and weight-lowering properties.|
