Does anyone tried to freeze dry essential oil. I need it in form of solid.. But mine just become more viscous. And still in liquid form
I am not sure what is your final purpose regarding solid, but certainly you can use liquid nitrogen to solidify your oil.
I am agree with Noel regarding loss of many components if you decide to produce solid at room temperature.
Project
At what vacuum should the rubber plugs be squeezed by the drying shelves so that the vacuum is kept in the bottle and the cork does not stick to the freeze drying shelf during its raising? Raising shelves occurs with vacuum, at atmospheric pressure?
Goal: correct freeze drying mode. vacuum preservation in a bottle. Rubber plugs should not adhere to the freeze drying shelves during lifting. The integrity of the tablets in the vial. Selection of a drying medium for live vaccines.
Dear Roberta
I think this article can help you.

The essential oil never freezes, but you can have a precipitation of one of the compounds generally sesquiterpenes C15. In the standards, essential oil can be stored under nitrogen at 6 C.
What you can do is to emulsify the essential oil in a water-soluble polymer such as Gum Arabic, then after emulsification, you can freeze-dry it to get a dry powder which consists of essential oil encapsulated in a polymer.
