Ensuring Compliance with Food Additives and Preservatives

Food additives testing is a critical step in verifying product safety and regulatory compliance. Under FDA 21 CFR regulations, manufacturers must ensure that ingredients like chemical preservatives and synthetic color additives remain within safe consumption limits (known as GRAS status).

Whether you are verifying the concentration of antimicrobial preservatives like Sodium Benzoate to inhibit microbial growth, or ensuring your synthetic dyes match their FD&C specifications for purity, our laboratory utilizes High-Performance Liquid Chromatography (HPLC) to deliver accurate data you can trust. We also verify label claims like 'Sugar-Free' via nutritional analysis.

Why Food Additives Testing Matters

Regulatory Compliance

Strict adherence to FDA limits for restricted food additives is non-negotiable to prevent costly recalls.

Labeling Accuracy

Verify claims such as "No Artificial Preservatives" and specific color declarations (e.g., "Yellow No. 5") with analytical proof.

Export Certification

Screen products for international export readiness, ensuring compliance with bans on specific dyes or synthetic antioxidants.

Targeted quantification methods and food additives testing for chemical preservatives and dyes.

Preservatives Testing & Quantification

Preservatives Testing

Common antimicrobial preservatives are essential for extending shelf life stability but are heavily regulated. Our specialized food additives testing protocols quantify these agents to ensure they are effective without exceeding FDA maximum usage levels. Ensure your food quality parameters like pH are optimal for preservative efficacy.

Analytes

Sodium Benzoate, Potassium Sorbate, Parabens (Methyl, Ethyl, Propyl), Sulfites (SO2), and Calcium Propionate.

Test Methods

HPLC-UV (High-Performance Liquid Chromatography) or Ion Chromatography for Sulfites.

Technical Specs

Sample Size: 100g | LOD: < 10 ppm | Shipping: Ambient or Refrigerated

Accreditation & TAT

ISO 17025 Accredited | 3-5 Business Days

Synthetic Dyes and Color Additives Analysis

Synthetic Dyes and Color Additives Analysis

The FDA requires batch certification for synthetic color additives used in food. We perform comprehensive food additives testing for synthetic dyes to detect the presence and concentration of the seven allowable FD&C colors, ensuring they meet strict purity specifications.

Analytes

FD&C Red #40 (Allura Red), Yellow #5 (Tartrazine), Yellow #6 (Sunset Yellow), Blue #1 (Brilliant Blue), Blue #2, Green #3, Red #3.

Test Methods

HPLC-DAD (Diode Array Detection) or UV-Vis Spectrophotometry.

Technical Specs

Sample Size: 100g | LOD: < 1 ppm | Shipping: Ambient (Protect from light)

Accreditation & TAT

ISO 17025 Accredited | 5 Business Days

Food Antioxidants Testing Laboratory

Food Antioxidants Testing Laboratory

Synthetic antioxidants are widely used to prevent lipid oxidation and rancidity in fats and oils. However, their use is strictly limited by weight of fat/oil content. Our food additives testing for antioxidants provides precise quantification to validate that your formulation remains within safe limits for consumer health.

Analytes

BHA (Butylated Hydroxyanisole), BHT (Butylated Hydroxytoluene), TBHQ (Tert-Butylhydroquinone), and Propyl Gallate.

Test Methods

HPLC or GC-MS (Gas Chromatography-Mass Spectrometry).

Technical Specs

Sample Size: 100g | LOD: < 5 ppm | Shipping: Refrigerated (Protect from light & air)

Accreditation & TAT

ISO 17025 Accredited | 5-7 Business Days

Common Questions About Additive Testing

Why is food additives testing important for regulatory compliance?
Food additives testing is essential to verify that your product meets strict regulatory limits set by agencies like the FDA. Ensuring ingredients such as preservatives and colors are within safe consumption levels (GRAS) helps prevent costly recalls and protects public health.
What specific preservatives do you test for?
Our laboratory commonly tests for antimicrobial preservatives including Sodium Benzoate, Potassium Sorbate, Sulfites, Parabens, and Calcium Propionate, which are widely used to extend shelf life in various food products.
How do you verify the purity of synthetic food dyes?
We use High-Performance Liquid Chromatography (HPLC) to analyze synthetic dyes (such as Red 40, Yellow 5, and Blue 1). This ensures they meet FD&C purity specifications and confirm accurate label declarations.
Can you detect prohibited additives or illegal dyes?
Yes, our advanced screening methods can detect unauthorized colorants (like Sudan dyes) and other non-permitted additives, ensuring your products are safe for both domestic consumption and international export.
What methods are used to quantify antioxidants in fats and oils?
We utilize gas chromatography (GC-MS) or HPLC to precisely quantify synthetic antioxidants such as BHA, BHT, and TBHQ. This confirms that these additives do not exceed the maximum allowed limits based on the fat or oil content.
What is the typical turnaround time for additives testing?
Standard turnaround time for most food additives testing requests is 5-7 business days. Expedited services may be available depending on the specific analytes and current laboratory capacity.
