Color Quality Control Ensures Yellow Mustard Brand Consistency


Posted on July 10, 2017

Brand Consistency Is an Essential Ingredient for Mustard Manufacturers

Brand consistency is a key product feature for manufacturers of yellow mustard. Simply put, yellow mustard needs to be yellow. Bottle after bottle, batch after batch, whether it’s being sold in Boston or Beijing, consumers expect their mustard to be exactly the same shade of yellow. If for some reason—variation in raw materials, or a mistake during the manufacturing process—the mustard isn’t yellow, customers are likely to notice. In the finicky world of food safety, off-color batches can cause damage to a company’s reputation. This damage can lead to a decline in sales and a loss of market share.

Spectrophotometers Ensure Objective Color Quality Control

To avoid this, manufacturers implement color quality control regimens. Before mustard is bottled, samples must be tested to ensure they are the proper color. This can be achieved rapidly and effectively with the aid of instrumental color quality control devices like spectrophotometers. These instruments measure color by assessing changes in bursts of light that they reflect off objects. This allows them to ascertain the exact shade of an object rapidly and accurately.

To implement color quality control in a mustard production process, manufacturers must test a representative number of samples. In the quality control lab, technicians should test these samples against a pre-programmed standard color.  If they return results within an acceptable tolerance range, the batches they represent are clear for bottling. If they return results outside the acceptable range, the batches should be corrected and retested before processing.

The use of instrumental color quality control is preferable over human observers for its reliability and recordkeeping. Human observers see color subjectively. We lack the language to describe color with any true degree of specificity. Further, we can be thrown off by differences in lighting or texture. Spectrophotometers, by contrast, measure color objectively. They describe color as a series of numerical values, with decimal accuracy. This not only allows for accurate measurement, but for objective documentation as well. As spectrophotometers use controlled lighting to measure color, they cannot be thrown off by ambient light conditions.
