Sucrose Acetate Isobutyrate丨CAS 34482-63-8

CAS: 34482-63-8
Chemical Formula/Abbreviation: C18H30O13

Sucrose Acetate Isobutyrate (SAIB) is a high-molecular-weight ester compound obtained by esterifying sucrose with acetic acid and isobutyric acid. It is typically a colorless to pale yellow, highly viscous liquid. Due to its excellent density-adjusting capabilities, good chemical stability, and compatibility in oily systems, Sucrose Acetate Isobutyrate is widely used in beverages, food additives, and related formulations, making it an important material in functional food formulations.

Sucrose Acetate Isobutyrate Key Features

Excellent density adjustment capability

Sucrose Acetate Isobutyrate has a high density and is often used to adjust the density difference between the oil and water phases, making it an important functional ingredient for achieving stable dispersion in beverage systems.

Excellent chemical stability

Under suitable processing and storage conditions, SAIB is not prone to hydrolysis or oxidation reactions and maintains stable performance over a wide temperature range.

Highly compatible with oily systems

This product exhibits excellent compatibility in vegetable oils, essential oils, and various lipid-soluble formulations, facilitating the formation of a uniform and stable system structure.

Mature application foundation

SAIB has been widely used in the food and beverage industry, boasting a long history of application, mature processes, and a well-defined quality control system.

Sucrose Acetate Isobutyrate Main Applications

Beverages and food additives

Sucrose Acetate Isobutyrate is commonly used as a weighting agent in oil-containing beverage systems to improve the dispersion stability of the oil phase and prevent separation or floating.

Fragrances and flavorings

In fragrance formulations, SAIB can be used as an oily carrier component, helping to stabilize the fragrance distribution and improve the physical stability of the system.

Functional food formulations

In the development of specific functional foods or special formulations, Sucrose Acetate Isobutyrate can be used as a structural modifying agent to optimize product appearance and stability.

Food industry

Due to its stability and established application history, SAIB is frequently used in laboratory research and pilot-scale development of food formulations.

Precautions

  1. It is recommended to store the product in a sealed, dry, and well-ventilated environment, avoiding prolonged exposure to high temperatures.

  2. Avoid contact with or storage alongside strong oxidizing agents, strong acids, or strong bases to prevent structural degradation.

  3. It is recommended to wear protective gloves during operation to avoid prolonged direct skin contact with high-viscosity liquids, which could cause injury.

  4. During production or use, excessive moisture should be prevented from entering the system to avoid affecting its stability.

  5. If SAIB accidentally comes into contact with the skin, wash thoroughly with soap and water; if any discomfort occurs, seek medical attention immediately.

  6. Waste materials must be disposed of in accordance with local regulations regarding food additives or organic ester chemicals, and must not be dumped indiscriminately.
