Borax, also known as sodium borate, is a chemical compound banned in many countries from use in food due to its potential health risks. However, some unscrupulous food vendors still use it to make noodles appear chewier and more elastic. The problem? It’s nearly impossible to detect by sight or taste — and vendors will rarely admit to using it.

But there's good news: you can test for borax in just 5 seconds using a simple trick at home.

❗ Why Borax Is Dangerous

While borax may improve the texture of noodles, it comes with a serious cost to your health. Prolonged exposure — even in small amounts — can lead to:

• Nausea and vomiting

• Reproductive issues

• Liver and kidney damage

• In severe cases, even cancer or death with prolonged consumption

That’s why detecting it early is key, especially in foods like fresh noodles, rice vermicelli, or tofu, which may be tampered with.

✅ The 5-Second Borax Test (Using Turmeric Paper)

All you need is turmeric test paper, which is available online or at most pharmacies and science stores.

How to Test:

1. Moisten the surface of the noodle slightly.

2. Rub or press a strip of turmeric paper against it.

3. Wait 5 seconds.

4. If the paper turns reddish-brown, borax is likely present.

🔬 Turmeric paper reacts with borax due to its alkaline properties, causing a clear color change that’s easy to spot.

🛡️ How to Protect Yourself

• Buy noodles only from trusted sources.

• Choose noodles that look natural — too white or too springy can be a red flag.

• Always rinse fresh noodles thoroughly before cooking.

• Keep a pack of turmeric paper in your kitchen if you often buy fresh noodles or rice products.
