Detect wax and oil coating for shine in brinjal
Inspection Guide

Brinjal Wax Coating Detection
Brinjals (eggplants) are often coated with wax or oil to give them an attractive glossy purple appearance and extend shelf life.
**1. The Shine Test:**
Natural fresh brinjal has a slight natural sheen but mostly a matte finish. If the brinjal looks like it's been polished with an unnatural, mirror-like glossy shine, it's wax or oil-coated.
**2. The Fingernail Scrape Test:**
Gently scrape the skin with your fingernail. If you can scrape off a waxy or oily layer (appears as white/clear residue under your nail), it's coated. Natural brinjal won't produce this residue.
**3. The Tissue Wipe Test:**
Wipe the brinjal with a dry tissue or cloth. If the tissue shows oily marks or waxy residue, or if the brinjal's shine reduces after wiping, it indicates coating.
**4. The Hot Water Test:**
Pour hot water over the brinjal. Wax coating will start to melt and appear as white streaks or patches. The surface will feel slippery or slimy.
**5. The Natural Texture Check:**
Natural brinjal skin has very fine, almost invisible wrinkles and slight texture. Wax-coated brinjals look perfectly smooth with no texture variation.
Quick Safety Tips
- Check for mirror-like glossy shine (unnatural)
- Fingernail scrape test for waxy residue
- Always peel brinjal if heavily wax-coated
- Wash with warm water and vegetable brush
