Ethyl acetate, one of the most common presently used solvents for printing food contact materials, could cause many sensory problems with its very low odor threshold of 10 mg/kg. Assuming a complete transfer of ethyl acetate from the packaging into the product, it is calculated that the threshold level in Table 13-6 is reached with a package surface area to product mass of > 1 m2/kg based on a content in the material of 10 mg ethylacetate per m2. This could only be the case for small packages or for foods with a low fill weight (e.g. potato chips). With the present state-of-the-art technology the residual amounts of ethylacetate are usually under 10 mg/m2 and can be monitored analytically without difficulty. 

These specialists utilize highly trained judges and sophisticated test designs and analysis to solve sensory problems. Consumer testing in most industry applications now is done with consumers. Even with the continuing development of instrumentation to replace the human judge, sensory analysis continues to expand its contribution to flavor analysis. 

As can be understood from the above sensory problem, data alone do not determine what is an object and what is a variable. This goes back to the problem definition. Only when a stated purpose of the data is provided can the nature of the ways be deduced.
