I am trying to make crunchie fruit chips, without a freeze drier, does anyone have information on any other process, excluding also conventional drying.
I think the Instant controlled pressure drop technique could help you in this issue.
If sugar content is not an issue you can improve the structure of conventionally dried fruit slices with a prior osmotic drying step-
Dry at low temperature with dehumidified air.. Circulate air @50 Deg C and RH less than 10%.
You can use a drum dryer, comparatively much cheaper than freeze dryer
After staining and solidifying my agarose gel, I load the first well of the dried agarose gel with the TrackIt Ladder (10488058) from Invitrogen and load my unstained DNA samples into the other...
