Black garlic has been used for thousands of years by oriental countries, especially in China and Korea, due to its medicinal properties. Recently, because its unique taste and flavor, black garlic has been utilized by great chefs in culinary in the occident. The bulbs of garlic develop black color by chemical and biochemical reactions, under determined controlled temperature and humidity. The final product eliminates the harsh and irritating compounds, and its antioxidant properties are increased, which have been related to the formation of phenolic compounds. This work aimed to study the physical and chemical properties of black garlic because very few scientific reports have been published. The black garlic bulbs were produced in our laboratory and some bought on the supermarket for comparison. Total soluble solids (TSS), pH, titratable acidity (TA), firmness, color and total phenolic compounds (Folin-Ciocalteu) were determined from bulbs and cloves in triplicate. Each 1.0 g of garlic was extracted with 10 mL of methanol at room temperature and centrifuged at 10,000 x g for 15 minutes. The supernatant was used to measure the total phenolic compounds. The data showed that the pH of black garlic (4.70) is much lower than the garlic in natura (6.67), confirmed by TA of black garlic that increased from 6.1 to 15%. On the other hand, TSS (23.00) in black garlic was greater than in natura (7.80). The mean of total phenolic contents in the commercial black bulbs were 377.00 mg GAE 100g-1 while the total phenolics in the in natura bulbs were 82.00 mg GAE 100g-1. This result indicates that black garlic has antioxidant properties (in vitro) enhanced by the chemical and biochemical reactions during the ageing process.
