Abstract

Host foods and associated microorganisms contain water which in the vacuun of an electron microscope would rapidly evaporate at ambient temperature . In addition constituent fats may melt under the electron beam. Cryopreservation and examination at low temperature avoids these problems. The structure of emulsified or foamed products can be revealed by freeze-fracture techniques. Products such as ice cream which are not stable even under normal pressures at ambient temperature can be prepared rapidly and examined for prolonged periods.
