100% tech grade d-limonene

A certain mainstream store near me has "100% tech grade d-limonene" for sale at an inexpensive price.

Is there any reason to suspect this would not be suitable for spice?

Last time I extracted was over a decade ago, I was living in a different country, and ordered my limonene from a supply shop that no longer exists. (Pinching myself) I was expecting more of a scavenger hunt. :lol:

If it's labelled correctly it should be fine. Sometimes orange oil terpenes get labelled as limonene and oxygenated minor components such as citral can make things get messy. Stirring - maybe while gently heating - a sample of it with solid caustic soda would inform of the presence of oxygenated terpenoids by producing a brown, tarry discoloration after some minutes.

The other thing to be wary of is any coloration in the product. Limonene should be a clear, water-white liquid. If it's orange that means it's expressed oil rather than steam-distilled and it will contain non-volatile impurities.

Awesome, thank you. That's great to know about the color - I've seen reviews for it in other places where people complained it was clear and not orange :lol:
