Bloom or gel strength:
It is a measure of cohesive
strength of cross-linkage that occurs between
molecules and is proportion to the molecular weight
of gelatin.
Bloom is determined by measuring the weight in grams
required to move a plastic plunger of 0.5inches in
diameter, 4mm into a 6
2/3
% gelatin that has held at
10°C for 17 hrs.
The unit of bloom is grams and it is between 150-250g
