Lipoic acid (LA), also known as α-lipoic acid, alpha-lipoic acid (ALA) and thioctic acid, is an organosulfur compound derived from caprylic acid (octanoic acid). [3] ALA, which is made in animals normally, is essential for aerobic metabolism. It is also available as a dietary supplement or pharmaceutical drug in some countries.
Thioacetic acid is an organosulfur compound with the molecular formula CH 3 C(O)SH. It is a thioic acid: the sulfur analogue of acetic acid (CH 3 C(O)OH), as implied by the thio-prefix. It is a yellow liquid with a strong thiol-like odor. It is used in organic synthesis for the introduction of thiol groups (−SH) in molecules. [4]

The preservation of foods has evolved greatly over the centuries and has been instrumental in increasing food security. The use of preservatives other than traditional oils, salts, paints, [clarification needed] etc. in food began in the late 19th century, but was not widespread until the 20th century. [2] The use of food preservatives varies ...
The combination of kojic acid, 10% glycolic acid and tranexamic acid “act synergistically for brightening skin overall and lightening dark spots,” says Castilla, who notes that it’s a ...
Colour retention agents are food additives that are added to food to prevent the colour from changing. Many of them work by absorbing or binding to oxygen before it can damage food (antioxidants). For example, ascorbic acid (vitamin C) is often added to brightly coloured fruits such as peaches during canning. [citation needed]
Acid is widely used as a preservative. In red wine, Sulfurous anhydride or sulfur dioxide (SO2), in particular, is the most frequently used source. [4] Acid protects wine from bacteria by regulating the pH value, which affects the growth and vitality of yeast during fermentation. [2] Acidity also directly affects color, balance and taste. [2]
In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...
