 Look for only foreign objects’ discoloration or unusual order in the spice.

-Taste test

Take a small sample of the spice and test it. If the taste differs then it may be an adult action chemical analysis have a laboratory Test the Spices for any substance.

-Thin layer chromatography (TLC)

This test is used to detect adulteration in species by separating the Components of the Sample and comparing them to a known one! Standard.

– High-performance Liquid Chromatography (HPLC)

This test is used to detect adulteration in Spices by separating the components.

-GAS chromatography

This is also the same technique but in advanced shape.

How to check adulteration in juices

Chemical Analysis

 Acidity test

This test is used to detect the presence of acids in juices. It was done by adding a few drops of phenolphthalein indicator to the juice sample. If the juices are acidic will turn pink or red.

Refractometer test

This test is used to detect the presence of sugar in juices. It’s done by measuring the refractive index of the juice sample.

Brix test

This test is used to detect the presence of sugar in juices.

Formaldehyde taste

This test is used to detect the presence of formaldehyde in Juices.

 PH test

 This test is used to detect the pH of Juice. Generally, mango juice has a pH of around 3.5 to 4.5. the pH of orange Juice is 3.3 to 4.2.
