Cranberry Harvesting and Processing Cranberry Juice

Cranberry – a fruit native to North America – is recognized for its bright red color, tart taste, and versatility for product manufacturing. Major cranberry products include cranberry juice, dried cranberry, cranberry sauce, frozen cranberry, cranberry powder, and dietary supplements containing cranberry extracts.

Every autumn (usually from mid-September until around mid-November in North America and March through May in Chile), cranberries reach their peak of color and flavor and are ready for harvesting. That’s when our growers harvest millions of pounds of cranberries. If you ask us, it’s really quite beautiful.
WET HARVESTING
A lot of people think that cranberries grow under water. Makes sense, since we usually see the berries floating on top of the water. But, what we’re seeing is actually the result of wet harvesting. The bog is flooded with up to 18 inches of water the night before the berries are to be harvested. The growers then use water reels, nicknamed “eggbeaters,” to churn the water and loosen the cranberries from the vine. Each berry has tiny pockets of air that allow it to float to the surface of the water. From there, they’re corralled together, loaded into trucks, and shipped off to become the Ocean Spray® products that fill your grocery aisles.
DRY HARVESTING
Fresh cranberries, the ones you buy in the produce aisle every fall, are harvested using the dry method. It’s the best way to get the absolute freshest of berries. For this, cranberry growers use a mechanical picker that looks like a large lawnmower. It has metal teeth that comb the berries off the vine and deposit them in a burlap sack at the back of the machine. Helicopters are sometimes used to transport the sacks to protect the vines from the traffic of heavy trucks.
Tales From the Bog: Inside a New England Cranberry Harvest | Oyster.comOnce the fruits are gathered from the marsh, they are transported to the facility for sorting, washing and grading for sale as a fruit, juice or for the pressing of oil. Each cranberry contains approximately 30 seeds of which takes approximately 15kg of cranberry fruits to produce as little 50mil of oil. That is a lot of cranberries!
Dry berries are taken to the plant to be sorted. Machines sort out unsuitable berries by bouncing them over a 1 in (2.54 cm) high “bounce board.” Firm, round berries bounce over the board, while rotten or bruised berries remain trapped and are discarded. Berries that clear the bounce boards are carried away by conveyor belts and are packaged by machines that check weight and package accordingly.
The beauty of this product (other than its inherent benefits) is that there is zero waste in the production of Cranberry Oil. The low-grade fruits are separated and used for the processing of the oil, because ultimately the seeds are all that are required to produce the oil. The seeds are dried, cold pressed, then filtered for the oil. The cold pressing process is 100% natural and does not require and processing aids. The by-product of the pressing process (the meal) is also utilised. This is a cracking antioxidant scrub that can be used in a wealth of cosmetic formulations.
