FSTest Nitrite Detection Kit

Rapid Semi-Quantitative Detection of Nitrites in Edible Bird’s Nest, Water & Food Samples

Nitrite (commonly sodium nitrite) is a potentially harmful food contaminant. Though permitted in small quantities for certain meat products, excessive levels may pose serious health risks — as little as 0.3–0.5g can cause acute poisoning or death. In bird's nest products, nitrite may form naturally during processing or storage and is strictly limited to 30 mg/kg under Chinese food safety regulations.

The FSTest Nitrite Detection Kit offers a simple, accurate, and rapid on-site screening solution for nitrite contamination in solid and liquid food products, especially edible bird’s nests, with colorimetric results in just 5 minutes.

Applications

This test is suitable for detecting nitrite residues in:

✔ Edible bird’s nest

✔ Noodles, rice flour, jellyfish, instant food

✔ Drinking water, herbal drinks, and clear liquids

✔ Export goods inspected by customs authorities

✔ Especially effective for bird’s nest exporters/importers complying with China GB standards (nitrite limit: 30 mg/kg).

How It Works – Testing Procedure

✅ For Liquid Samples

Use colorless or lightly colored liquids directly as test solution.

✅ For Solid Samples (e.g., bird’s nest)

Chop 1g of sample finely.

Add 10mL distilled water and sonicate for 10 mins (or stir + stand for 5 mins).

Centrifuge if needed, then collect the supernatant as test solution.

✅ Color Development & Result Reading

Pipette 1mL test solution into a 1.5mL tube.

Add 1 drop each of Detection A and B. Shake well.

React for 5 minutes, then compare color with the standard chart:

• Light pink = low/none

• Purple-red = high nitrite concentration

Storage Conditions

Store sealed in a cool, dry place, 4–30°C

Shelf life: 12 months

Keep away from light and humidity
