Determination of hemicellulose, cellulose and lignin contents of dietary fibre and crude fibre of several seed hulls. Data comparison

The contents of hemicellulose, cellulose and lignin in neutral-detergent fibre, and acid-detergent fibre in hulls of hazelnuts, peanuts, coconuts, sunflower seeds, pumpkin seeds, acorns and chestnuts were determined. Similar cell-wall characteristics for sunflower-acorn, peanut-pumpkin and hazelnut-chestnut pairs can be deduced from their similar composition. High amounts of hemicellulose and lower ones of cellulose and lignin are dissolved in the process of determining crude fibre. The results are discussed.
