Cinnamon — Visual Screen for Cassia Bark

This is a substitution check, not a safety alarm

FSSAI recognizes cinnamon and cassia as distinct spice products. Cassia is therefore not automatically an illegal adulterant when it is correctly sold and labelled as cassia. The Kitchen Check question is whether thicker cassia bark has been substituted or presented as cinnamon.

What DART says to look for

FSSAI DART describes cinnamon bark as very thin and capable of being rolled around a pencil or pen. Cassia is thicker and shows several layers between rough outer and smoother inner layers. The visual difference is easiest on whole bark, not powder.

Use the label first

A package marked 'cassia' should not fail because it looks like cassia. A package marked 'cinnamon' deserves closer review if most pieces look strongly cassia-like. Kitchen Check should always show the claimed product beside the visual result.

Do not test powder visually

Once the bark has been ground, thickness and rolling structure are lost. Colour alone cannot reliably distinguish cinnamon powder from cassia powder. The app should disable this test for powder and say that botanical or compositional confirmation needs a different validated method.

Aroma is supportive, not decisive

DART mentions cinnamon's distinct smell, but aroma changes with age, storage and individual smell sensitivity. The app should not make the user taste or chew bark. Shape and layers are the main consumer observations.

Natural pieces will not all look identical

Whole spices vary naturally, and broken pieces may be harder to interpret. Kitchen Check should look at several representative pieces rather than one fragment. If the sample is mixed or unclear, avoid a firm accusation.

Recommended result wording

Use 'Appearance consistent with the declared product', 'Visual result unclear', or 'Product sold as cinnamon but several pieces look strongly cassia-like—substitution screen suspicious'. Do not label cassia itself as unsafe.

Use several intact bark pieces

A broken fragment may be too short to show the rolling structure clearly. Kitchen Check should ask the user to inspect several intact pieces when possible. If most pieces are thin, delicate and tightly rolled, that supports cinnamon-like appearance; if most are thick and strongly layered, that supports cassia-like appearance. The result is still a substitution screen, not botanical laboratory identification. A mixed sample should be marked unclear rather than forced into one category.

Do not force the pencil-roll step

If the bark is too short or brittle, do not bend it aggressively around a pen. The roll description is a visual aid, not a requirement to break the product. Thickness, quill structure and layers can usually be inspected without damaging the sample. A damaged or mixed sample should be marked unclear.

This check is for whole bark only.
