The gel strength tester is suitable for testing the breaking strength, elasticity, ductility, tensile strength, adhesion and recovery of gel, pectin, silica gel, gellan gum, carrageenan, agar, arabic gum, xanthan gum, konjac gum and guar gum. Gel strength tester is also called freezing strength tester, gelatin gel strength tester, tissue analyzer or freezing strength tester.
Meet standards:
1. The national standard GB6783-2013 Food Additives Gelatin contains the determination method of gel strength.
Prepare a specified concentration of gelatin solution, and after the sample solution preparation process such as standing still, water bath heating, stirring, and dissolution, and cold water bath, take and place it in a specific sample cup. Select a specific gel test probe to conduct puncture test on the central point of the sample cup. Thus, the strength of gel can be measured.
2. European Pharmacopoeia EP 8.0.
Cylindrical probe: 12.7 ± 0.1 mm; Sample: Gelatin solution with a concentration of 6.67% at 10 ℃; Sample bottle specification: 59 ± 1 mm (inner diameter) * 85mm (height); Speed during testing: 0.5 mm/s; Penetration depth: 4 mm
Test method of gel strength tester: take 7.5g of the sample to be tested and put it into the sample bottle, add 105ml of water, cover it and keep it still for 1-4 hours, heat it in a 65 ± 2 ℃ water bath for 15min, and stir it during the heating process of the water bath. Cool at room temperature for 15 minutes, then add a rubber stopper and place the sample bottle in an ice bath at 10.0 ± 0.1 ℃ for 17 ± 1 hour. Wipe off the water on the outer wall of the sample bottle and measure the gel strength. The measuring point is the center point of the sample surface. Take the average value of the peak points of the two groups of measured curves as the reported value of gel strength, in Bloom g.
