The second process involves the hazelnuts. Once the hazelnuts have arrived at the processing plant, a quality control is issued to inspect the nuts so they are suitable for processing. A guillotine is used to chop the nuts to inspect the interior. After this process the hazelnuts are cleaned and roasted. A second quality control is issued by a computer-controlled blast of air, which removes the bad nuts from the batch. This ensures that each jar of Nutella is uniform in its look and taste. Approximately 50 hazelnuts can be found in each jar of Nutella, as claimed by the company.
