Cashew Chemical Whitening Detection

Cashews are bleached with chemicals to appear whiter and oiled excessively for glossy appearance. 1. The Paper Towel Test: Place cashews on a white paper towel or tissue for 5 minutes. Natural cashews release minimal oil. If you see: - Large oil stains spreading on paper - Translucent marks - Excessive oil absorption It indicates heavy oil treatment to mask oldness or improve appearance. 2. The Color Comparison Scale: Natural cashews are ivory/cream colored with natural variations - some lighter, some slightly darker. Chemically whitened cashews are: - Bright artificial white (like chalk) - Uniform color across all nuts - Lack natural cream undertones Very white cashews = bleached with chemicals. 3. The Taste Test: Natural cashews have a mild, natural sweet flavor. Chemically treated cashews may taste: - Bitter or chemical aftertaste - Metallic flavor - Rancid if old and oil-coated to hide age - Lack of natural sweetness 4. The Surface Shine Test: Hold cashew under light. Natural cashews have a slight natural sheen but mostly matte finish. Chemically treated cashews look: - Unnaturally glossy and shiny - Wet appearance from excessive oil - Mirror-like reflection 5. The Smell Test: Natural cashews have a mild, pleasant, nutty aroma. Chemical-treated cashews may smell: - Chemical or like sulfur - Rancid (if old and oil-coated) - Lack natural aroma
