Wild blueberry farming and processing enterprise keeps a keen Eagle eye on product quality with advanced user-friendly X-Ray product inspection system.
Not all blueberries are created equal. It’s a fact that many consumers freely take for granted without much afterthought, but it’s one that also drives a lot of hard work and research done by many Canadian farmers and processors doing business with the Quebec Wild Blueberries Inc. co-operative.
As a key commercial agent for local Quebec wild blueberry farmers and processors, Quebec Wild Blueberries insists on maintaining a high level of quality excellence throughout the value chain to ensure its international clientele reaps all the sought-after health benefits of the fruit, as widely noted in many health studies, as well as to enjoy its uniquely sweet taste profile well after the harvest.
Unlike cultivated blueberries produced and packed in mass commercial quantities, wild blueberries naturally pack more flavor into their blue spheres, while also producing a higher content of anthocyanin—a strong antioxidant that helps kill free radicals in the human body.
As such, anthocyanin is widely lauded as an effective natural aid for preventing cell and tissue damage that could potentially lead to cellular disease and illness.
According to a recent study conducted by Dr. Wilhelmina Kalt of Agriculture and Agri-Food Canada, “The blue pigment that is found in wild blueberry skin contains a high concentration of anthocyanins that have property to destroy free radicals in the human body, which are responsible for diseases like cholesterol, diabetes, cancer, etc.
“As it also turns out,” Kalt points out, “the concentration of anthocyanins in wild blueberries is higher than in most fruits found in the Americas.”
Other research even suggests additional berry health attributes in helping to prevent early onset of memory-related diseases such as Parkinson’s and Alzheimer’s dementia.
While many such claims remain to be validated scientifically, there is nothing doubtful about the high Vitamin C content and the awesome taste of Quebec wild blueberries grown across the province for hundreds of years.
Over time, wild blueberries have steadily become a staple ingredient for chefs and recipes all over the world—retailing far and wide in fresh, frozen, dehydrated and concentrated formats and formulations.
Widely used in beverage production and canned products, it is also a popular natural ingredient in a wide range of desserts, baked goods and commonplace breakfast fare like cereal, yogurt, pancakes, waffles, muffins, jams, etc.
Founded in 1984 in the heart of the Lac Saint-Jean region—about 200 kilometers north of Quebec City—the Quebec Wild Blueberries enterprise enjoys enviable proximity to some of the best-tasting blueberries anywhere in the world, according to many food authorities.
With the product now reaching customers in over 30 countries—including the U.S., China, Japan, Australia, France, Belgium, South Korea, Italy, Spain, Germany, Switzerland, U.K., The Netherlands, Israel and Mexico—wild blueberry farming today ranks as the second-largest agricultural activity in the Lac Saint-Jean region after the dairy sector. According to Quebec Wild Blueberries director of operations Pascal Hudon, the co-op’s growers annually collect a combined total of 65 million pounds of wild blueberries from the designated picking areas across the region—all within a very tight time-frame between August and mid-September.
During the month of June, wild blueberry fields turn white as the plant’s flowers bloom, and then into a sea of blue as the fruit ripens through early the beginning of August. That’s when the wild blueberries—visibly smaller than their cultivated cousins—are ready to be harvested.
As Hudon explains, the Quebec Wild Blueberries farm operators use special rakes to collect the organic wild blueberries in the forested areas, whereas the nonorganic wild blueberries are picked in the fields using mechanical or semi-mechanical picking methods.
Once harvested, the tiny fruit are immediately shipped to one of the company’s four nearby processing plants in Saint-Bruno, Saint-Félicien, Dolbeau or Newport, where they are graded for size, individually quick-frozen (IQF) and stored in a clockwork-like process that keeps Quebec Wild Blueberries sufficiently stocked to be able to ship its product to customers throughout the year.
“The wild blueberries are picked, sorted, packaged and frozen at a steady pace for about 35 to 40 days,” Hudon explains. “As soon as the fruit is picked, we transport it to one of our four ice plants, where workers place them into containers of differing sizes, depending on the precise specifications of each of our customers.
“Doing it this way ensures that we maintain all the high-quality aspects of the wild blueberries that our customers expect,” Hudon states.
For international customers, Hudon explains, the blueberries are maintained in their frozen state through shipping to make sure the bulk product arrives at the clients’ processing facilities in perfect condition.
Boasting both ISO 9001:2000 quality management and HACCP (Hazard Analysis Control Critical Points) food safety certifications, the company’s facilities maintain in-house laboratories, a biological research department, and well-qualified technicians to help ensure optimal product quality control and safety, backed up by strategic investment in leading-edge quality control technologies.
In May of 2015, for example, the Saint-Bruno facility installed a brand new model Pack 400 HC X-Ray product inspection system, manufactured by Eagle Product Inspection and distributed in Canada by the Orangeville, Ont.-based automated packaging systems integrator PLAN Automation.
“We selected this system for the Saint-Bruno facility primarily because of its ability to detect the inclusion, and to activate the removal of, small shards of glass, metal fragments, mineral stones, some plastic and rubber compounds, and even calcified bone materials,” says Hudon, saying the new X-Ray detector was expertly integrated into the plant’s packaging line, which also includes:
- a THS 21 metal detection system from CEIA S.p.A., supplied by Saint-Julie, Que.-based Techno Pak;
- product coding and marking systems manufactured by Linx Printing Technologies and Markem-Imaje Inc.;
- a fully-automatic Ishida weighscale, and a Vegatronic series vertical bagger manufactured by ILAPAK, both supplied by Techno Pak.
As Hudon relates, the plant’s management did extensive market research and a lot of legwork before selecting the Pack 400 HC X-Ray detector.
“We visited a number of industrial trade shows and then went into many factories that utilized a metal detection and/or X-Ray system, so that we could see how each worked in real-life situations,” Hudon recalls.
“After members of our team organized their own thoughts, we sat down together and discussed our analysis until it was crystal clear which equipment best met our needs,” says Hudson.
“Ultimately, we determined that the safety inspection unit that best matched our current and future needs was what Eagle Product Inspection was offering,” says Hudon, citing important value-added features such as:
- improved robust construction featuring thicker stainless steel and plates cut and welded together, rather than bolted, to eliminate possible food debris collection points;
- an AMI (American Meat Institute)-approved sanitary design and the IP69K rating required for reliable food inspection in harsh wash-down environments;
- interlocked hinged louvers that are easily lifted to allow access to the conveyor—eliminating the need to dismantle traditional heavy louvers to clean inside the machine—and easy belt removal.
The Pack 400 HC X-Ray system provides 400-mm of detection coverage at the belt, according to Eagle Product Inspection, and is capable of high-speed imaging of up to 60 meters (200 feet) per minute.
“The overall system design and the ease of cleaning ultimately convinced us to purchase the Pack 400 HC X-Ray system,” says Hudon.
“It is refreshingly easy to use and easy to clean: unlike some similar products from other manufacturers that almost require a university degree to maintain on a daily basis,” he notes.
“Because we work around the clock, five-days-a-week, cleaning our facility and equipment is a daily challenge,” says Hudon, complimenting the Eagle X-Ray detector’s ability to withstand the Saint-Bruno’s plant’s challenging cold-room environment.
“We needed to find a high-performance machine that was also capable of operating in cold environments where we have to keep the product chilled at a temperature of around -30°C,” says Hudon, also
citing the availability of PLAN Automation’s Quebec office in Boucherville as another deciding factor.
“It was a key selling point for us that there was local service available should we ever have a problem with the new X-Ray unit,” Hudon states. “Having PLAN Automation nearby means less downtime for
us should anything happen.” So far, the new Pack 400 HC system at the Saint-Bruno facility has performed as well as promised, Hudon confides. “We are so pleased with the performance
achieved by the Pack 400 HC system at the Saint-Bruno plant, that we are currently in the process of installing a second such unit at our Saint-Félicien facility.
