发明人：FROST JOHN W
权利人:UNIV MICHIGAN STATE
摘要:The present invention provides a bioengineered synthesis scheme for the production of gallic acid from a carbon source. Methods of producing gallic acid from a carbon source based on the synthesis scheme are also provided. The gallic acid produces from these methods can be further converted to pyrogallol. Methods for the biosynthesis of pyrogallol from gallic acid are also provided.

摘要:The present invention provides an emulsifying agent that can suitably be used to stabilize oil-in-water emulsions and that is prepared from natural ingredients without the use of organic solvents or chemical synthesis. n The invention provide a process of preparing such an emulsifying agent, said process comprising: n• providing a plant-derived starting material containing: no reducing monosaccharides; no phenolic compounds; no free amino acids; no pectin; and no of water; n n• heating the starting material to a temperature of at least 60°C for at least one minute to produce an emulsifying agent; n nwherein at least 95% of the dry matter contained in the starting material is plant-derived; and wherein the absorbance at 405 nm of the emulsifying agent is at least 0.05 units higher than that of the starting material.

摘要:Metal and metal oxide nanoparticles can be prepared via a simple synthesis by using a hydrolysable gallotannin, such as tannic acid, to reduce a metal precursor compound and to act as a stabilizer for the resultant nanoparticles. By controlling the molar ratio of hydrolysable gallotannin to metal precursor and/or the initial pH of the reagents one can achieve control over the size and polydispersity of the resultant nanoparticles. In particular, the controlled addition of a metal precursor into a solution of the hydrolysable gallotannin, as described herein, can yield small nanoparticles, for example 1 nm to 40 nm diameter nanoparticles, with low polydispersity. The methods disclosed herein can be performed at room temperature.
