Hyperspectral imaging (hsi): applications in animal and dairy sector

Abstract

Hyperspectral imaging (HSI), also known as imaging spectroscopy or 3D spectroscopy, combines imaging and spectroscopy into a single system. With a high resolution measurement of spectral signatures, HSI is able to provide critical information of the target. Thus it is useful for various scientific and industrial applications, including food safety and disease diagnosis. Due to constantly increasing demands for safe animal products, there is pressure on the processing sector for applications of advanced, high throughput methods for non-destructive quality analysis of animal products. In this context, HSI finds its applications for grading, classification, quality & composition analysis of animal products including meat, egg, milk etc. Further, the technique is also a useful tool in poultry sector for assessment of wholesomeness and quality control of chicken carcasses, as well as, chicken meat products. In fish industry also, the technique has established its potential for determining freshness and quality attributes of sea-foods. Apart from quality control of animal products, HSI has also demonstrated its usefulness for disease diagnosis in animal models and for detection of mammary cancers in dogs. Thus, the future of HSI technology in animal industry is promising and associated with multivariate analysis, HSI technique will further dominate in animal products authentication and analysis in the future also.

Trends in feed evaluation for poultry with emphasis on in vitro techniques

“…Thus, not only the feed ingredient or complete feed type but also their other physical properties need to be considered ( Jha and Tiwari, 2016 ). Although, in NIRS technique several quality parameters can be analyzed simultaneously but, it is unable to determine distribution of chemical constituents within the sample ( Wu et al., 2008 ; Kumar et al., 2016 ). There is new technique called hyperspectral imaging (HSI) or imaging spectroscopy which combines properties of imaging and spectroscopy.…”

“…The HSI technique is able to provide simultaneous detection and quantification and localization of chemical constituents of the sample. Due to combined features of imaging and spectroscopy, HSI has become a promising technique for non-destructive food quality, as well as, safety analysis, particularly in the meat industry, the technology has gained significant attraction ( Kumar et al., 2016 ).…”

Advanced Multi-functional Sensors for In-situ Soil Parameters for Sustainable Agriculture

“…It was designed to collect light in the visible, near-infrared, and short-wave infrared (SWIR) spectrums between 400 nm and 2500 nm. 28 In a field study conducted in Illinois and Missouri, HSI was employed to study soil fertility parameters such as P, K, Ca, Mg, pH, EC, and organic matter. Here, a PLSR model was used to characterize the soil fertility based on the reflectance data.…”

Hyperspectral imaging of the degradation of meat and comparison with necrotic tissue in human wounds

“…In recent years HSI has found its way into several areas such as environmental science, agriculture, food, pharmaceuticals, medicine and others. 1 In the food industry it is used, amongst other applications, for monitoring meat quality and analysis of meat composition (muscle, intramuscular fat, subcutaneous fat, water etc.). [2][3][4] Due to its non-invasiveness, HSI in the visible and near infrared (NIR) spectral range from 500 nm to 1000 nm has been proved to provide a large amount of relevant information about physiological parameters (e.g.…”
