[0002] γ-Aminobutyric acid (GABA), as an important inhibitory neurotransmitter, not only plays a role in the central nervous system of animals, but is also widely used in the food and pharmaceutical fields due to its physiological effects such as lowering blood pressure and improving sleep quality. In order to obtain high-purity GABA, an extraction device is required in the production process to perform steps such as fermentation, purification, and crystallization. These steps are essential to achieve efficient conversion and fine separation of products, thereby ensuring the quality and safety level of the product and meeting the requirements of food-grade standards. By optimizing the purification method and crystallization process, GABA products with higher purity and yield can be obtained.
