Food analysis and sorting

Food analytics and sorting by NIR
Food analysis and sorting by NIR

Strict guidelines and regulations in food industries result in a high demand for analytical control of raw materials and products. The analytical control is commonly provided by expensive and time-consuming laboratory-based methods. NIR-spectroscopy is a fast and cost-efficient alternative for many applications. Solids, powders, granulates, pastes and liquids can be analysed by NIR spectroscopy either after easy sampling or directly on a conveyor belt in a non-contact measurement.

Portable NIR-spectrometer are used for incoming goods inspection or for a quantitative rapid analysis of the nutrient composition in food. The imaging NIR process spectrometer uniSPEC1.7HSI and uniSPEC1.9MPL-24V allow a wider range of applications. Easy integration of the spectrometer components in industrial plants provides non-contact inline NIR measurements for control purposes. Fresh produces such as fruit, vegetables, meat and fish or convenience and bakery products can be controlled. Either the detection of foreign materials or identification of sub-standard goods by semi-quantitative analysis of nutrients is available.

Application Foreign Body Detection

Whether fruits or vegetables (e.g. apples, tomatoes, onions, beans or berries,...), the products can be quickly and reliably identified by using NIR technology uniSPEC1.7HSI to detect impurities such as wood, paper, plastics, stones or insects. As a result, this technology is ideally suited for the usage in optical sorting systems. In contrast to conventional RGB sensor systems, differences in colour and shape between product and impurity is are not necessary for a successful sorting process.

The identification using NIR technology is based on differences in the chemical composition. Therefore, leaves, branches, stems and shells of the same colour can be distinguished. The hyperspectral measurement technology is able to reliably detect and accurately analyse objects with up to a minimum size of 2 mm (standard model). Special lenses are optionally available to reduce the minimum size up to 0.5 mm. Due to high spatial resolution and a very fast measurement speeds, processes can be safely monitored even at conveyor belt speeds of up to 2 m/s. The identification routines are created specifically for each sorting task and adapted to customers requirements upon request.

Application Content Analysis

The hyperspectral imaging NIR technology uniSPEC1.7HSI can be used for semi-quantitative Analysis of carbohydrates and for determining the water content. LLA technology can be integrated directly into the production process. The measurement is contact-free e.g. installed above a conveyor belt.

Such systems will be applied for
■ the analysis of quality class in the respective product,
■ determination of the optimal degree of the maturity or
■ early detection of bruises

The analysis result can be visualised for each location point. Additionally, for homogeneous products, an object related analysis result is available. The result can be used for a monitoring solution or a sorting process.

Application spatially resolved compounds analysis in laboratory analytics

A spatially resolved quantitative analysis of carbohydrates as well as the determination of water content on a laboratory scale can be quickly and easily performed with the hyperspectral scanning system ProScan-HSI in combination with uniSPEC1.7HSI. The measurement is carried out contact-free without any extensive sample preparation. The analysis result of the whole samples is available within seconds either as false color image to evaluate the homogeneity or displayed as statistical object-related analysis result. The identification routines are customized and calibrated towards the results of the reference analytics. This may cover customer-specific limit values, e.g. in semi-quantitative applications.
