Changes in Membrane Permeability During Rehydration of Freeze-Dried Weissella paramesenteroides LC11

An Improved Test to Study the Changes in Membrane Permeability During Rehydration of Freeze-Dried Weissella paramesenteroides LC11

The objective of this study was to assess changes in membrane permeability during rehydration of freeze-dried Weissella paramesenteroides LC11. Viability was assessed using the electrical conductivity measurement (ms cm -1 g -1 dry weight) and the plate count method (cfu g -1 dry weight). The symptoms of injury included an increase in the electrolyte leakage during the first 4 h of rehydration ...

Rehydration characteristics of freeze-dried avocado (Persea americana)

The avocado is a tropical fruit whose nutritional value is due mainly to its high lipid content. The aim of this work was to evaluate the rehydration of freeze-dried avocado (variety Collinson) powder and slices. The rehydration kinetics was determined using an experimental apparatus that monitored the volume of water absorbed by the sample with the time. Peleg and Weibull equations were used t...

Freeze-dried B.C.G.

Freeze-dried B.C.G. of British manufacture became available for experimental work in 1955. The main reason for introducing it was the need for a vaccine which would retain its potency under conditions of prolonged storage. On reconstitution for injection the vaccine should produce a uniform suspension with minimal clumping, resulting in a uniform viable bacterial count. These properties mean th...
