Description:

The presence of proteins in environment provides for a hotbed for rapid propagation of microorganisms;  and the protein itself is one of the vital structure components of bacterial cells.  The FSTest surface hygiene test card is a paper-based testing sensor that reacts with protein residue on tableware and food processing equipment by changing colors.  By comparing the results with the standard colorimetric card, the hygiene degree of surface is semi-quantitative evaluated.
