Garlic breath is allegedly alleviated by eating fresh parsley. Abundant sulfur compounds in garlic are also responsible for turning garlic green or blue during pickling and cooking. Under these conditions (i.e., acidity, heat) the sulfur-containing compound alliin reacts with common amino acids to make pyrroles, clusters of carbon-nitrogen rings.
Laba garlic is a vinegar-preserved garlic from Chinese cuisine. Its refined color is green or blue and its taste is sour and slightly spicy. Because it is usually made in the 8th day of the 12th month of the Chinese Lunar calendar, the Laba Festival, it was named Laba garlic.

Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air.

The Gallic acid reagent is used as a simple spot-test to presumptively identify drug precursor chemicals. It is composed of a mixture of gallic acid and concentrated sulfuric acid. [1] 0.05 g of gallic acid is used for every 10 mls of sulfuric acid. [2] The same ratio of gallic acid n-propyl ester in sulfuric acid can also be used. [3]
Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
