Fanchi-tech on Candy Industry or Metallized Package

If candy companies are switching to metallized packaging, then maybe they should consider food X-ray inspection systems instead of food metal detectors to detect any foreign objects. X-ray inspection is one of the first lines of defense to identify the presence of foreign contaminants in food products before they have the chance to leave the processing plant.

Americans need no new excuses to eat candy. In fact, the US Census Bureau reported in 2021 that Americans consume about 32 pounds of candy year-round, much of it is chocolate. Over 2.2 million metric tons of chocolate are imported annually, and 61,000 Americans are employed in manufacturing sweets and treats. But Americans aren’t the only ones who have sugar cravings.  A US News article reported that in 2019 China consumed 5.7 million pounds of candies, Germany consumed 2.4 million, and Russia 2.3 million.

And despite the cries from nutritional experts and concerned parents, candy plays a dominant part in childhood games; one of the first being the board game, Candy Land, with Lord Licorice and Princess Lolly.

So it comes as no surprise that there is actually a National Candy Month – and it’s June.  Started by the National Confectioner’s Association — a trade association that advances, protects and promotes chocolate, candy, gum and mints – National Candy Month is used as a way of celebrating over 100 years of candy production and its impact on the economy.

“The confectionery industry is committed to providing consumers with information, options and support as they enjoy their favorite treats. Leading chocolate and candy makers have pledged to offer half of their individually wrapped products in sizes that contain 200 calories or less per pack by 2022, and 90 percent of their best-selling treats will display calorie information right on the front of the pack.

This means that candy manufacturers may have to adjust their food safety and production technologies to accommodate new packaging and ingredients. This new focus may affect food packaging demands because they may require new packaging materials, new packaging machinery, and new inspection equipment – or at least new procedures and methods throughout the plant. For example, metallized material that is automatically formed into bags with heat seals on either ends may become more common packaging for candy and chocolates. Folding cartons, composite cans, flexible material laminations and other packaging alternatives may also be customized for new offerings.

With these changes, it may be time to look at the existing product inspection equipment and see if the best solutions are in place.  If candy companies are switching to metallized packaging, then maybe they should consider food X-ray inspection systems instead of food metal detectors to detect any foreign objects.  X-ray inspection is one of the first lines of defense to identify the presence of foreign contaminants in food products before they have the chance to leave the processing plant. Unlike metal detectors that offer protection from many types of metal contaminants encountered in food production, X-ray systems can ‘ignore’ the packaging and find virtually any substance that is denser or sharper than the object containing it.

If metallized packaging is not a factor, maybe food processors should upgrade to latest technologies, including multiscan metal detectors, where three frequencies are run to help get the machine close to ideal for any type of metal you might encounter. Sensitivity is optimized, as you also have the optimal frequency running for each type of metal of concern. The result is that the probability of detection goes up exponentially and escapes are reduced.
