Artificial gastric juice consisting of Aqua bidest / ultrapure water, sodium chloride and hydrochloric acid is used to simulate the digestive process under controlled laboratory conditions. This single solution enables the study of drug dissolution, food decomposition and the interactions of ingredients with the gastric environment.

The chemical components of the solution are aqua bidest / ultrapure water (CAS No.: 7732-18-5), sodium chloride (NaCl, CAS No.: 7647-14-5) and hydrochloric acid (HCl, CAS No.: 7647-01-0). The hydrochloric acid gives the artificial gastric juice its acidic pH, which is similar to that of natural gastric juice. Ultrapure water serves as the solvent, and sodium chloride simulates the natural salt content in the stomach.

The reactions and chemical properties of the solution are controlled by the interaction between the components. The acidic environment created by the hydrochloric acid reacts with the various samples to allow chemical transformations and releases or dissolution of substances relevant to the study.

Possible results that can be obtained from the use of artificial gastric juice include the evaluation of drug release kinetics or the chemical stability of drugs and food ingredients under gastric juice-like conditions. In conclusion, artificial gastric juice can be described as an important tool for studying the gastric environment and the reactions of substances in the stomach.
