The Elastic Properties of Gelatin Jellies.

Thermal Degradation of Gelatin as Applied to Processing of Gel Mass

“…1) characterizes the gelatin rigidity in a form analogous to the stress-strain diagram of an elastic body, confirming earlier observations (12). However, the lack of a welldefined dimensional relation with respect to the force, area, and deformation in the penetrative type of compression precluded the calculation of rigidity or shear modulus.…”

“…The viscosity degradation of the gel mass differs substantially from that of the dilute gelatin; instead of a fifth-order decay, the kinetic data follow more closely a second-order model as defined by: Earlier work had shown that the rigidity of the gel mass was higher than that of the dilute gelatin not only because of the increased gelatin concentration but also because of the additional rigidity contributed by molecular interactions with plasticizers such as glycerin (12,15). For a specific composition of the gel mass, however, the rigidity is expected to be proportional to the rigidity of the dilute gelatin in the standard 6% concentration.…”

The protein of intermediate moisture meat stored at tropical temperature

“…What the nature of the protein breakdown and crosslinking reactions are one can only speculate but glycerol is known to crosslink proteins (Sheppard & Sweet, 1921;Hatschek, 1932;Gelatin Res. SOC.…”

An improved method for measurement of gel strength and data on starch gels

“…As no change was observed in gel strength after 15 minutes, this time of heating was chosen as standard. Data obtained with d iffer ent sizes of disks embedded various depths in Amaizo cornstarch gels are given in table 7. It was found t hat the concentrated pastes could not be prepared in b eak ers and then transferred to other containers.…”

“…Of these, mention may be made of the ASTM [1]1 and Fuchs [2] penetrometers, the Bloom [3] gelometer, the TalTBaker [4,5] gel tester, the Brimhall-Hixon [6] rigidometer, the Sheppard [7,8] torsion dynamometer , the Rosinger-Vetter [9] static-loading membrane method, and the Saare-Martens [10] disk method. All of these have specific advantages.…”
