Conventional chemical preservatives used in prevention of food spoilage caused by microorganisms have shown adverse effects and found to be of low effectiveness. This challenging situation stimulated research to find alternatives. As a result, numerous natural product-based compounds have been patented for use as antimicrobial food preservatives. These compounds comprise phenolic and non-phenolic ones. The phenolic agents include mainly those composed of a single aromatic ring and flavonoid-derived molecules. The phenolic compounds display multifunctional activities, while the nonphenolic do not. Polyhydroxybenzene derivatives exhibit high potential as effective antimicrobial or as antioxidants agents. Among the later category is 1,2,3,4-tetrahydroxybenzene (THB). THB has been recently patented as a highly effective antimicrobial and antioxidant agent. It showed significant and broad-spectrum antimicrobial activity versus a wide range of grampositive, gram-negative bacteria, yeasts, and fungi, including pathogenic and non-pathogenic organisms. Its effectiveness as an antioxidant is equal or superior to commonly used antioxidants such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). Production of 1,2,3,4-tetrahydroxybenzene was accomplished efficiently by adopting a bioengineered synthesis, that is recently disclosed. In addition, there is also a patented simple chemical method.
