STABILITY OF MONK FRUIT SWEETENER SIAMENOSIDE I UNDER ACIDIC AND THERMAL CONDITIONS AND ITS DEGRADATION PRODUCTS
AbstractThis study evaluated the stability of siamenoside I, a minor sweet component of Siraitia grosvenorii (Monk Fruit), under pH and temperature conditions representative of commercial beverage storage, as well as under photostability conditions. Mock beverage solutions, formulated to ~500 mg/L siamenoside I, were prepared at four pH values (2.8-4.2)) and stored at temperatures of 5°C-40°C for 26 weeks and degradation products were quantified at scheduled intervals. Under all conditions, siamenoside I exhibited high stability. Six known degradation products/impurities (compounds 3,6,7,8,9 and 14) were detected at levels ≥0.500 mg/L (≥0.100% of the starting concentration). Photostability testing indicated minimal degradation under fluorescent light exposure. No changes in appearance were observed; all samples remained colorless and clear. Siamenoside I in mock beverages demonstrated chemical stability under conditions simulating both typical and extreme commercial beverage storage and handling, including light exposure, supporting their suitability for use in acidic, ready-to-drink formulations.
