Frequently Asked Questions (FAQ): Extenders in Food and Spice Adulteration

1. What are food extenders made of?

The term extender is often used for protein-rich ingredients, whereas filler refers mainly to powders with a high carbohydrate content. A wide range of ingredients can be used, both as fillers and extenders for food: grain flour, cellulose, oats, or olive stone flour. In foods where the extender/filler is also supposed to add nutritional properties, chia seeds, chinoa or ground beans are also popular options. Certain foods also contain mineral powders such as precipitated silica.

There is little specific data about the most widely used spice adulteration powders. Most well known are mineral powders such as chalk, starch, sawdust or grain flour, but researchers also mention quite peculiar options such as lead chromate, argemone, ground papaya seeds, tomato skin or different fruit/vegetable husks.

Identification of adulterants in spices by visual or sensory means is generally difficult, if not impossible.

Certain ingredients used for spice adulteration can be detected by means of reactivity, aroma, or water tests. Chemicals added for spice adulteration can also be identified through appropriate reactive testing.

4. What is the most adulterated spice?

There are different studies that evaluated the percentage of spices in which adulterants were found. The top ranking spices were – among others – oregano, cardamon, pepper, curcuma, saffron and chili/paprika.
