'Importing' freeze dry

Freeze drying sublimes frozen water out of frozen produce, under vacuum. I have heard that the "pores" in food remain open under vacuum meaning that the food can be dried more effectively than...:

Dehydrating typically involves evaporating liquid water out of room temperature, or even slightly warmer, produce

If I were to guess, nutritionally, keeping food at a higher temperature until the water evaporates may lead to certain nutritional components degrading more than if the produce is frozen. Query also the likelihood of bacterial spoilage.

I got the backcountry freeze dried ones at the Supermarket in Picton. I think it may have been a Fresh Choice supermarket.

Thanks for all the info. I have spoken with AQIS and done further searches on the ICON database. Meat is a definite no go, certain vegetarian should be ok. Have ordered some, will find out in 10 days or so if my interpretation of the rules is right!!

Cheers for the replies!
