Method for measuring hardness of compressed solid food with low dispersion

The invention discloses a method for measuring the hardness of compressed solid food with low dispersion. The method is based on the basic principle of a physical property tester, and overall design and test evaluation are carried out on main factors influencing the hardness measurement result of the compressed solid food according to the quality characteristics of the compressed solid food. The relatively stable parameter ranges of the influence factors are as follows: the distance between the support frames is 50mm, the speed before the test is 0.75 mm/s-1. 25mm/s, the test speed is 1mm/s-1.5mm/s, and the triggering force is 50g-90g. The hardness measurement result obtained by the method is small in dispersion, high in stability and good in reproducibility; a set of standard and stabletesting method is provided for hardness evaluation of compressed solid food products, scientific basis and technical support are provided for formula process research and taste quality improvement, and reference can also be pr
