چکیده انگلیسی


• Hyperspectral imaging using a number of devices has been applied to freeze-dried broccoli florets.
• Quantification and localisation of total glucosinolates in florets has been examined.
• The spectral region between 950 and 1650 nm was optimum.
• Glucosinolate compounds were mainly located in the external part of florets.

The use of hyperspectral imaging to (a) quantify and (b) localise total glucosinolates in florets of a single broccoli species has been examined. Two different spectral regions (vis–NIR and NIR), a number of spectral pre-treatments and different mask development strategies were studied to develop the quantitative models. These models were then applied to freeze-dried slices of broccoli to identify regions within individual florets which were rich in glucosinolates. The procedure demonstrates potential for the quantitative screening and localisation of total glucosinolates in broccoli using the 950–1650 nm wavelength range. These compounds were mainly located in the external part of florets.
