Cultivar and Environment Effects On Fiber Composition of Wheat Bran.

During wheat milling, a large amount of by-product, wheat bran, are disposed as waste. The high percentage of water-insoluble fiber could be advantages for wheat bran as reinforcing material. We have explored the effect of cultivars and environments on bran components such as dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (Cell), hemicellulose (Hemi), calcium (Ca), fat, starch, and acid detergent lignin (ADL) of six cultivars grown in three different environments. The DM, ash, Ca, Cell, starch, and ADL contents were influenced by environments and along with CP and fat, the ash and Ca contents were also influenced by genotypes. All of the bran components were influenced by environment and genotype interactions. We observed significant negative correlation of Cell with CP and ADL which make wheat bran a suitable reinforcing material however surface treatment of bran fiber would make it more efficient.
