Artificial Tactile Sense Technique for Predicting Beef Tenderness Based on FS Pressure Sensor

摘要

We present a rapid system for predicting beef tenderness by mimicking the human tactile sense. The detection system includesa FS pressure sensor, a power supply conversion circuit, a signal amplifier and a box in which the sample is mounted. Asample of raw Longissimus dorsi (LD) muscle is placed in the measuring box; then a rod connected to the pressure sensor ispressed into the beef sample to a given depth; the reaction force of the beef sample is measured and used to predict the tenderness.Sensory evaluation and Warner-Bratzler Shear Force (WBSF) evaluation of samples from the same LD muscle are usedfor comparison. The new detection system agrees with established procedure 95% of the time, and the time to test a sample isless than 5 minutes.
