FlavScents AInsights Entry: Locust Bean Gum (CAS: 9000-40-2)

1. Identity & Chemical Information

• Common Name(s): Locust Bean Gum, Carob Gum
• CAS Number: 9000-40-2
• FEMA Number: Not applicable
• Other Identifiers: E410 (European food additive number)
• Material Type: Natural complex material derived from the seeds of the carob tree (Ceratonia siliqua)
• Key Constituents: Primarily composed of galactomannans, a type of polysaccharide

Locust bean gum is a natural thickening and gelling agent extracted from the seeds of the carob tree. It is a polysaccharide consisting mainly of galactose and mannose units. The gum is valued for its ability to form viscous solutions and gels, which are used in various food and industrial applications.

7. Toxicology, Safety & Exposure Considerations

Locust bean gum is considered safe for consumption with no significant toxicological concerns at typical use levels. It is non-irritating and non-sensitizing for dermal exposure, making it suitable for use in both food and cosmetic applications. Inhalation exposure is minimal due to its low volatility.

8. Practical Insights for Formulators

Locust bean gum is valued for its ability to improve texture and stability in formulations. It synergizes well with other hydrocolloids like xanthan gum to enhance gel strength and viscosity. Formulators should be aware of its potential to form lumps if not properly dispersed in water.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
