Quantitative Descriptive Analysis (Tragon QDA®), spider plots, and Product Optimization (PROP™) are but a few of the commonly used sensory tools that were invented by Tragon. Today, that tradition of doing things better continues. Our direct-data entry system is unrivaled in its abilities; our proprietary algorithms will create a serving block that balances both the products’ fixed position and relative position (Latin squares balances only the fixed position) regardless of the number of products in the study. In 1974 Tragon was a pioneer in the field of sensory evaluation – that proud tradition continues today.
