I have a freeze dry machine and am thinking of freeze drying glands first as freeze dry stuff can be turned into fine powder easily. If you want fresh gland lure just add water or urine and instantly you’d have fresh paste gland lure. If you want it rotted mix and let rot for a super creamy paste. Anyone heard of doing this. Also freeze dry stuff sealed properly lasts practically forever.

Very intresting idea and concept. Be great if it works. Only way to know for sure if the odor and pheromones stay true after freeze drying and re hydration would be to do some comparison testing. Glands would be much easier to grind freeze dried. Let us know what your results are after testing, I'd be very intrested.

When food is properly freeze dried and packaged it keeps nutritional quality 25 years. Freeze dried ice cream is really weird. It is super lite but the second you put it in your mouth it turns creamy and feel and tastes the same as fresh except it’s not cold. I’m confident freeze dried and then powdered glands would be great. It would be super concentrated so a learning curve on how much powder to use. If aging just add enough water to make thickness desired and age

As long as ur confident they are great they will be then

Your probably one of those that tell how good a lure is by smelling it to.

I can see it working well on Food and Beaver Castors.
Most glands are Fatty or Oily. How do you dry Oil?
Also many Glands benefit greatly from rotting down for several years!!!
I would like to see You try it. Then let us know if it works?
The Old methods of grinding, rotting, ageing are hard to beat imho!

Not freeze dried, but I’ve been known to spread some glands out and let them dry just a bit.

I don’t have a fancy, powerful, high speed grinder so stuff with a lot of connective tissue (like glands) is always a royal pain in the a$$ to grind.

I’ve found letting em get just a little tacky makes grinding a lot smoother process.

Oil and do not Freezdry well although when pets are freeze dried they last if done right for decades and they have lots of fat in them. But as far as glands go the Freezdry process does nothing to alter the glad except to dry all tissue. Freeze dry skin is far easier to powder than air dried because it dosnt shrink when drying and becomes very porus. Freeze drying works by turning the moisture to ice crystals and then slowly gets extracted out the pours. You have to have the specimen froze solid at the beginning of the process if you don’t want shrinkage. If not frozen it will greatly distort when 6 tons of vacuum becomes present. You can have the specimen chamber at 65 degrees above and put a glass of water in and turn it on and when the microns reach a certain level the water will begin violently boiling and then instantly freeze solid. Yes freeze solid at room temperature. Anyway back to oil and greasy gland substances. After freeze drying these glands will be super easy to turn to a super fine medium. Even a blender will do this No need to grind. Then you can handle the glands the same as you always have like rotting for years or adding fresh to lures or baits. Nothing has changed in the gland except it’s consistency and there is zero moisture in it. There are 2 types of freeze dry machine. The small ones they sell for doing small amounts of food which actually get hot during the process and get product done very fast. Or machines for freeze drying flowers or taxidermy or food which work at subzero temperatures and is a very slow process. A machine like mine to buy now would be around $40,000. It’s 52” long and 24” diameter.
