본 발명은, 알칼리 금속염 존재 하에, 3-하이드록시프로피온산을 300 g/L 이상 포함하는 농축액에서 3-하이드록시프로피온산염의 결정을 형성하는 단계 및 상기 농축액에서 3-하이드록시프로피온산염의 결정을 분리하고 3-하이드록시프로피온산을 전환하는 단계를 포함한 3-하이드록시프로피온산의 회수 공정과, 상기 3-하이드록시프로피온산염의 결정에 관한 것이다. Provided is a process of recovering 3-hydroxypropionic acid and a crystal of 3-hydroxypropionate, wherein the process includes the steps of: forming a crystal of 3-hydroxypropionate in a concentrate containing 3-hydroxypropionic acid in an amount of 300 g/L or more of in the presence of an alkali metal salt; and separating the crystals of 3-hydroxypropionate from the concentrate and converting into 3-hydroxypropionic acid.
