ABSTRACT A mechanical tester with punches of different sizes and shapes was used to determine the effect of penetration speed, penetration depth, and gelatin concentration on the resistance of gelatin gels to penetration. Penetration speed in the range of 0.04–0.12 cm s‐1had no significant effect on force readings. A straight line relationship existed between the square of gelatin concentration and penetration force. Depth of penetration was found to be an important factor in the measurement of the mechanical behaviour of the material. Coefficients of determination showed a high correlation between punch shape, circumference, depth of penetration, gelatin concentration and force readings.
