‘Nut’ is used to describe a wide range of seeds with a seed coat or shell. Because of high-energy content, micronutrients and positive global health impact, nuts have been present for centuries in human diet. However, over recent decades they have increasingly been found to induce adverse health effects. With an increasing number of individuals affected with allergenic reactions, nuts allergies are a growing global concern. Nuts are common food allergens and are the leading cause of fatalities from food-induced allergenic reactions in developed countries. Allergenic conditions arising from the consumption of nuts are generally thought to be life-long and typically severe. No definite treatment is yet available for nut and seed allergies. Dietary avoidance is the primary way to manage these allergies and requires the ability in the food industry to identify peanuts or tree nuts…

Hyperspectral imaging combines digital imaging with precise spectral information in each image pixel. It enables composition mapping in food and agricultural raw materials and products based on differences in the spectral signatures of the various chemical ingredients. Advances in hyperspectral cameras and image processing solutions are now making hyperspectral imaging an efficient tool for high throughput laboratory analyses, and even making it possible to apply it on-line in quality assurance and process control applications.
Near infrared (NIR) spectroscopy is widely used in the global agri-food industry for the non-destructive assessment of both the compositional and physical characteristics of a wide range of raw materials and finished products. This is particularly so in the cereals and related industries where, following the commercial development of suitable NIR instrumentation in the 1970s, the technique rapidly became the main means of determining a range of compositional properties which form the basis of trading operations worldwide.
