Global snack sales totalled $374 billion annually ending March 2014—an increase of 2 percent year-on-year. That’s because more consumers are snacking today than ever before and snacking more frequently. In fact, it’s estimated that on average, 24 percent of our daily calorie intake comes from snacks. With nearly one in four calories consumed outside a meal, the snack is no longer just a treat; it’s become a fourth meal.
As public scrutiny of food manufacturers continues to escalate and consumers increasingly turn to social media to voice complaints, snack processors have become more reliant on food inspection equipment to protect consumers and reduce the risk of brand-damaging product recalls in order to stay ahead of their rivals.
However, many snack applications can prove challenging for traditional product inspection equipment.
Why Are Snacks Such a Challenge to Inspect?
The unique challenges manufacturers face when striving to produce safe and quality-assured snacks can be summarized in the following issues.
Variety of potential contaminants. Often snacks contain a wide variety of ingredients that are all open to different types of contaminants. Fruits, vegetables, and nuts may be contaminated with stones or a piece of wire from the farm, while dairy products can be suspect to metal or plastics from processing.
High salt content of products. Many snacks, such as nuts and potato chips, contain high doses of salt and are conductive. When they pass through a metal detector, they can create a disturbance of the detection field, triggering false rejects. Product temperature and moisture content can also affect a metal detector’s detection sensitivity.| | | Next → | Single Page
