Bone contamination occurs regularly in all types of packaging (boxes, bottles, jars, cans, pouchers) and in all food industries. We are talking about chicken, pig and/or beef bone particles. Bone is a light product with a low Sg value. Nevertheless, bone can generally be detected. That’s because the X-ray systems measure the calcium in the bone and see it as contamination. Therefore, the bone must be calcined. (Cartilage is not bone and contains no calcium!)
Many chicken products are processed in the food and therefore the remains of chicken bone frequently occur as contaminants.
Bone residue contamination should always be tested to determine whether detection is possible
ScreenTec therefore always tests with bone contamination to determine the validation of the screening.
Normally parts of about Ø3mm can be found.
