FSTest Borax Boric Acid Test Card (20 Tests/Kit)

Product Overview

The FSTest Borax Boric Acid Test Card is an ultra-fast, user-friendly screening solution designed for the qualitative and semi-quantitative detection of borax and boric acid in food products. Borax and boric acid are toxic chemical compounds illegally added to foods by some vendors to artificially enhance elasticity, texture, and shelf-life, despite posing severe health risks to human organs. This highly portable test card empowers food processors, market regulators, and quality control inspectors to filter out adulterated food lots instantly.

Test Principle

This product modernizes classic food chemistry for modern field deployment based on the time-tested traditional turmeric chemical reaction. When the test card reacts with borax or boric acid in a dried state, it undergoes a distinct color transformation used for visual determination:

Target Industries & Applicable Matrices

This kit is highly recommended for meat processing facilities, industrial bakeries, noodle manufacturers, wholesale food markets, and health inspection departments. It is fully optimized for screening a wide range of common consumer staples, including:

· • Meat & Seafood Products: Pork, beef, fish, and shrimp meatballs, as well as meat stuffing.

· • Pastries & Desserts: Various desserts and baked pastries.

· • Traditional Staples: Rice dumplings, rice noodles, and related grain items.

Key Advantages & Application Scenarios

· Optimized for Field Use: Requires no heavy laboratory machinery, centrifuges, or pipettes. The testing workflow is entirely self-contained, requiring only basic auxiliary items (like a beaker, scissors, and a hair dryer), making it perfect for mobile food carts, kitchens, and receiving docks.

· Dual-Verification Technology for High Reliability: Features an optional built-in dual-confirmation mechanism. By moistening the white tablet on the card, folding it to overlap with the yellow tablet, and reopening it, operators can observe a much clearer color result, ensuring maximum accuracy and minimizing false negatives.

· Trace-Level Detection Limits (LOD): Offers high sensitivity across different food states, tracking down to 50 mg/L for liquid samples and 250 mg/kg for solid food matrices.

Simple Step-by-Step Assay Procedure

Achieve clear, semi-quantitative visual validation in minutes by following these steps:

1. Sample Preparation:
• Solid Samples: Cut 10 g of food into small pieces, add it into a beaker with 50 mL of pure or distilled water, and let it soak for 5–10 minutes. (Note: If the solution contains heavy fat or grease, filter it through filter paper first).
• Liquid Samples: Collect the supernatant directly; it is immediately ready for analysis.

2. Card Immersion: Take a test card out, tear off the top cover film, and insert the yellow tablets directly into the sample solution.

3. Drying & First Reading: Take the card out and dry it completely using the hot air setting of a hair dryer. Match the resulting color (yellow/gray vs. orange/reddish brown) against your reference standard to determine a semi-quantitative result. (Always run a pure or distilled water sample alongside as a blank control).

4. Optional Double-Check (Dual-Confirmation): Moisten the white tablet of the card with pure water, fold the card tightly to overlap the yellow and white tablets, then open it up to read a much clearer, highly reliable color presentation.
