Usage

General Description

Aspartic acid, homopolymer is a biodegradable and non-toxic substance that is used in a variety of industries, including food and pharmaceuticals. It is a polymer made up of repeating units of aspartic acid, a non-essential amino acid commonly found in the human body. As a food additive, it is used as a thickening agent and stabilizer, and it can also be used in medical applications as a drug delivery system. It is known for its environmentally friendly properties, as it is easily biodegradable and does not accumulate in the environment. Additionally, aspartic acid, homopolymer is considered safe for consumption and has been approved for use in various food and pharmaceutical products.

PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
