What is Carbohydrase From Aspergillus Oryzae?
Carbohydrase from Aspergillus oryzae is an enzyme preparation sourced from the fungus Aspergillus oryzae. Carbohydrases are a class of enzymes that catalyze the breakdown of carbohydrate molecules into simpler sugars. The Aspergillus oryzae strain has a long history of use in fermentation and food production, particularly in Asian food manufacturing where it is employed in sake, miso, and soy sauce production.
Enzyme preparations derived from Aspergillus oryzae are generally recognized as safe microorganisms in food processing. However, the specific commercial formulation with CAS number 977017-32-5 has limited publicly available documentation regarding its exact substrate specificity and intended applications.
Common Uses
While the precise applications for this specific enzyme preparation are not clearly documented, carbohydrase enzymes are typically used in food manufacturing to:
- Break down complex carbohydrates into fermentable sugars
- Improve texture and consistency in processed foods
- Enhance enzymatic processes in fermentation
- Modify starch properties in baked goods and other products
Aspergillus oryzae-derived enzymes have traditional applications in Asian food fermentation industries, suggesting this preparation may be used in similar contexts, though specific product applications require manufacturer documentation.
Safety Assessment
Aspergillus oryzae is classified as a safe organism for food use and has a history of safe use in traditional fermentation. The microorganism does not produce known mycotoxins and is distinct from pathogenic Aspergillus species.
According to FDA records, there are zero reported adverse events and zero recalls associated with this specific enzyme preparation, indicating no documented safety issues in commercial use. However, the lack of adverse event reports does not necessarily indicate comprehensive safety data has been published or that the additive has undergone extensive formal safety testing.
As with all enzyme preparations, potential considerations include:
- Allergenicity: Some individuals may react to fungal-derived enzymes
- Purity specifications: The safety of enzyme preparations depends on manufacturing standards and contaminant levels
- Thermal stability: Processing conditions may affect enzyme activity and safety
Individuals with mold sensitivities should exercise caution with fungal-derived enzyme preparations.
Regulatory Status
This additive does not hold FDA GRAS (Generally Recognized As Safe) status in the United States, meaning it has not undergone the formal GRAS notification process. This does not indicate the substance is unsafe, but rather that formal GRAS documentation has not been submitted to or accepted by the FDA.
The lack of GRAS status suggests limited commercial use in the United States food supply. Enzyme preparations may be regulated differently depending on their specific application and whether they remain active in the final food product.
International regulatory status varies by country. Aspergillus oryzae-derived enzymes may have different approval status in the European Union, Japan, and other regions with established food enzyme regulations.
Key Studies
Public scientific literature on this specific enzyme preparation (CAS 977017-32-5) is limited. Published research on Aspergillus oryzae and its enzyme products generally supports the safety of this organism in food applications, but detailed toxicological or efficacy studies specific to this formulation are not readily available in open-access databases.
Research on Aspergillus oryzae in fermentation demonstrates the organism's safe application in traditional food manufacturing. However, systematic safety data on this particular carbohydrase formulation would require review of manufacturer documentation or proprietary research databases.
Further information about this additive's intended use, substrate specificity, and safety testing would require direct contact with manufacturers or regulatory submissions.
