Hyperspectral imaging (HSI) technology is increasingly being used as a
dynamic analytical tool for food inspection. HSI creates a spatial map of
spectral features that enables the identification of material components and
their spatial distributions. Being a non-destructive and non-contact technique with
the ability to simultaneously determine several parameters in real time, hyperspectral
imaging has become particularly successful in the space of food assessment.
Scitech presents the Hyperion hyperspectral imaging system from Camlin
Photonics, a complete end-to-end solution for making robust, reliable, accurate
and repeatable hyperspectral measurements that are easily adaptable to a wide
variety of processes and applications. Hyperion provides users with an
all-in-one system that can measure, display, prepare calibration models and
analyse HSI data, with a clearly defined workflow.
Hyperspectral imaging is widely used in food assessment and inspection
applications including effectively determining many parameters of fruit and
vegetable quality such as the presence of bruises or damage, pH, soluble
solids, as well as the colour and appearance of skin; measuring cereals and
other grains to identify a number of key characteristics such as size, shape,
colour and appearance; investigating the chemical composition of kernels and
oils; and measuring chemical composition of dairy products.
Hyperspectral imaging is also applied to different red meat species to
predict freshness, assess tenderness, and determine fat, protein, collagen, and
water levels as well as colour, drip loss, and pH. The technology can also be adapted
to predict the freshness of fish by analysing the effects of storage conditions
and storage times, chilling and freezing, blood and melanin spots, and amino
and fatty acids, as well as detect the presence of bones in fillets.
Additionally, hyperspectral imaging can be used to strengthen high speed
sorting and grading as it allows for the excellent determination of substandard
products, contamination, presence of foreign bodies and defects.
