Understanding the Multiple Codes for Maltodextrin
Maltodextrin is a common food ingredient and a versatile substance used in many industries, from pharmaceuticals to cosmetics. Given its widespread use, it is identified by several different types of codes depending on the context. The question, "What is the code for maltodextrin?" can have several correct answers depending on whether you're dealing with food regulations, chemical inventories, or international shipping. This article breaks down the primary identifiers associated with maltodextrin to provide a clear understanding of each one.
The Maltodextrin CAS Number: 9050-36-6
The most definitive and universally recognized code for maltodextrin from a chemical perspective is its Chemical Abstracts Service (CAS) registry number, which is 9050-36-6. The CAS number is a unique numerical identifier for chemical elements, compounds, and alloys. It is essential for researchers, chemical suppliers, and regulatory bodies worldwide to ensure they are referencing the same substance. For maltodextrin, this single number points to the exact polysaccharide produced from the partial hydrolysis of starch, regardless of its source (e.g., corn, potato, rice) or its specific dextrose equivalent (DE) value.
The Maltodextrin E-Number: The E1400 Nuance
For food labeling and regulation within the European Union, substances are often assigned an E-number. The E-number commonly associated with starch derivatives like maltodextrin is E1400. However, there is a critical distinction to be made: E1400 is the code for dextrin, a broader category of starch hydrolysis products. In the EU, maltodextrin is typically considered a bulk ingredient rather than a food additive due to its nutritional properties as a carbohydrate. This means it often does not require an E-number and is simply listed on ingredient labels as "Maltodextrin." This nuance is important for both consumers and food manufacturers to understand when interpreting product labels. The classification depends on the specific function and degree of hydrolysis.
The Maltodextrin HS Code: A Trade-Specific Identifier
For international trade and customs, maltodextrin is classified under a Harmonized System (HS) code. This is not a single code but a category-based system, and the specific code can vary based on the product's characteristics and the importing country's regulations. The general HS code for dextrins and modified starches is typically within Chapter 35, with specific sub-headings for different types. Some relevant HS codes for maltodextrin and related products found in trade data include:
- 35051000: General code for dextrins and other modified starches.
- 17029090: Another frequently used code for maltodextrin, particularly certain forms or those with a higher Dextrose Equivalent (DE).
- 17029050: Specifically for maltodextrine and syrup.
The dextrose equivalent (DE) value, which measures the degree of starch hydrolysis, is a primary factor in determining the correct HS code for customs declaration.
FDA Status in the United States
In the United States, the Food and Drug Administration (FDA) regulates maltodextrin under its "Generally Recognized as Safe" (GRAS) status. The specific regulation for maltodextrin as a direct human food ingredient is 21 CFR Part 184.1444. This status indicates that the substance is considered safe by experts and is not subject to the extensive premarket approval process required for food additives. This is a crucial distinction in the U.S. regulatory landscape compared to the EU's approach.
Comparison of Maltodextrin Codes
| Code Type | Identifier | Purpose | Applicability | Context-Dependent? |
|---|---|---|---|---|
| CAS Number | 9050-36-6 | Unique chemical identification | Global | No, it is the same for the chemical compound. |
| E-Number | E1400 | European food additive classification | European Union | Yes, applies to dextrin, but maltodextrin often listed as an ingredient. |
| HS Code | 35051000, 17029090, etc. | Customs and international trade | Global | Yes, depends on product specifics (e.g., DE value). |
| FDA GRAS Status | 21 CFR 184.1444 | U.S. food safety and regulation | United States | No, applies to the substance itself as safe. |
Conclusion
Ultimately, there is no single answer to what is the code for maltodextrin. Instead, the correct identifier depends on the industry and the specific purpose. For a chemist, the CAS number 9050-36-6 is the key. For a European food manufacturer, it's understanding why maltodextrin is typically an ingredient and not an additive like E1400. For an importer, the specific HS code is critical for clearing customs. For the average consumer, recognizing maltodextrin on an ingredient list is the most important takeaway. For those seeking authoritative information on US food safety, the FDA's GRAS status and its corresponding regulation are the key references.
