Transglutaminase enzyme

The most critical factor is Enzyme Activity, usually measured in Units per gram (U/g). Standard commercial concentrations typically range from 100 U/g to 1000 U/g. You must also verify the Carrier Material (such as Maltodextrin or Sodium Caseinate), as this affects solubility and application. Ensure the product has a high pH stability range (typically 5.0 to 8.0) and an optimal reaction temperature (40°C to 55°C) to suit your specific food processing needs.

As a food additive, Transglutaminase must meet strict safety standards. Buyers should prioritize suppliers with ISO 22000 or FSSC 22000 Food Safety Management Systems. For global market access, HALAL and KOSHER certifications are often essential. Additionally, ensure the supplier provides a Certificate of Analysis (COA) for every batch and complies with FCC (Food Chemicals Codex) or local regulations like FDA (USA) or EFSA (EU) regarding GRAS (Generally Recognized as Safe) status.

TG Enzyme is highly application-specific. For Meat Processing (e.g., restructured steaks), you need a formula that excels at protein cross-linking to improve texture and sliceability. For Dairy Products (e.g., yogurt), the enzyme is used to increase viscosity and reduce syneresis (whey separation). In Bakery, it strengthens the gluten network. Always specify your end-use to the supplier so they can provide the correct enzyme-to-substrate ratio and formulation.

Transglutaminase is bio-active and sensitive to environmental factors. It must be stored in a cool, dry place (below 20°C), though refrigeration (4°C) is preferred for long-term stability. The product is typically vacuum-sealed to prevent oxidation. Once the packaging is opened, the activity level can drop rapidly; therefore, look for suppliers offering moisture-proof aluminum foil packaging and check that the shelf life is at least 12 months under sealed conditions.

Request temperature-controlled logistics (Cold Chain) if the transit time exceeds two weeks in hot climates. Ensure the supplier uses vacuum-packed aluminum bags and sturdy outer cartons. It is highly recommended to conduct a third-party activity assay upon arrival to verify that the U/g levels match the COA provided by the seller.

Focus on Tiered Pricing based on enzyme activity levels rather than just weight. Request pre-shipment samples for lab testing (usually 50g-100g). Negotiate for customized formulations if your production line has specific pH or temperature constraints. For long-term contracts, seek price stability clauses to protect against fluctuations in raw material costs (like fermentation media).

Utilize Secured Payment services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For large bulk orders, consider using a Letter of Credit (L/C) or a 30% deposit with the 70% balance payable after a third-party inspection (e.g., SGS or Intertek) confirms the quality and enzyme activity.

Ensure the supplier provides a clear HS Code (typically 350790) and a detailed Material Safety Data Sheet (MSDS). Some countries require a Health Certificate or a Non-GMO Declaration. Verify if your local customs requires an import permit for biological agents to avoid costly delays at the port.
