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, sun- flower seeds, p u m p k i n seeds, acorns and chestnuts were determined. Similar cell-wall characteristics for sunflower-acorn, peanut-pumpkin and hazelnut-chest- nut pairs can be deduced from their similar composi- tion. High amounts of hemicellulose and lower ones of cellulose and lignin are dissolved in the process of de- termining crude fibre. The results are discussed.
