, it became evident that the main contribution to the regression model comes from a region around 890-930 nm. A smaller contribution can be found around 960-980 nm. The region around 960 nm is known to contain the second overtone from the O–H bond in water molecules [25]. This may seem contradictory, but the C–H bond in starch may, according to Williams and Norris [25], have a strong absorption band at 979 nm. This may explain the positive contribution from this area. 878 and 901 nm are also pointed out as two starch absorption bands by Williams and Norris
