Common adulterants: Sugar, glucose and sugar syrup If a cotton ball dipped in honey burns right away, the honey is pure; otherwise, it is not.
Common adulterants: Chalk powder, lead chromate and metanil yellow To verify purity, add one teaspoon of turmeric powder into a glass of warm water. Without shaking or stirring, let it sit for 20 minutes. If the powder settles at the bottom during this time, the turmeric is pure; if it dissolves, it indicates potential adulteration.
Common adulterants: Vegetable oil, starch and vanaspati In a bottle, combine a pinch of sugar with a teaspoon of melted ghee. Shake the mixture thoroughly. After five minutes, inspect for a colour change to red; if observed, it indicates the presence of vegetable oil.
Common adulterants: Brick powder and artificial colours To assess purity, place a tablespoon of red chili powder into a glass of water and stir thoroughly. If the particles settle at the bottom, it might indicate the presence of brick powder. Conversely, if the water's colour transforms into a bright red hue, it suggests the potential use of artificial colours.
Common adulterants: Wax coating To determine purity, gently scrape the peel of an apple. If you observe a white substance, it indicates the presence of wax. Another method is to pour hot water over apples to check for the same.
Common adulterants: Chalk powder To test for purity, combine a tablespoon of salt with a glass of water. If the water turns white and particles settle at the bottom, it suggests the presence of chalk powder.
Common adulterants: Water, urea, starch, detergent and synthetic milk If you place a drop of milk on a slope and it runs down leaving a white trail, the milk is pure. Otherwise, if there is no white spot, it likely contains water.
Common adulterants: Palm oil, engine oils, argemone oil and paraffin Place coconut oil in the refrigerator; if it solidifies, it is genuine. Otherwise, if it remains in a liquid state, it likely contains adulterants.
