Konica Minolta CR-410FF French Fry Colorimeter

Konica Minolta CR-410FF French Fry Color Index Meter

Konica Minolta CR-410FF French Fry Color Index Meter: The Golden Standard for Food QA/QC

In the fast-food processing and large-scale French fry/potato chip manufacturing industries, the color of the product after emerging from the frying oil is a critical factor determining brand quality and consumer acceptance. A standard batch must have a uniform golden-brown doneness, without being over-burnt or too pale. The Konica Minolta CR-410FF French fry color index meter is the ultimate specialized optical measurement instrument, helping to digitize food color standards with absolute accuracy.
