How to Inspect Poha (Flattened Rice)
Poha is often colored with turmeric (natural) or synthetic dyes to appear more attractive. It can also contain iron filings from processing machinery.
1. The Tartrazine Test:
Soak Poha in warm water for 15 minutes. If it releases a bright, fluorescent yellow color into the water, it likely contains synthetic dyes. Turmeric releases a milder, natural yellow.
2. The Iron Filings Check:
Run a magnet through a heap of Poha. If any black particles stick to the magnet, these are iron filings which are dangerous if ingested.
3. The Dust & Impurity Test:
Place Poha in a sieve and shake it. Check the residue below. Excessive white dust or black particles indicate poor processing or unhygienic storage.
4. Texture & Smell:
Natural Poha has a mild rice aroma. If it has a musty or chemical smell, or feels unnaturally hard/brittle, it may be old or poorly processed.
