| Abstract: | The effects of solvent extraction and drying on neutral detergent fiber (NDF) values of foods of high sugar content were evaluated. It was found that Soxhlet extraction with a 1:l mixture of acetone and petroleum ether resulted in 117% higher NDF value for raisins than was observed for the untreated sample. This solvent mixture extracted approximately 5wo as much lipid material as did diethyl ether. The addition of sugar as glucose or sucrose and cooking at low boil for five minutes did not affect the NDF value of whole wheat flour. However, cooking caused the 1:l acetone petroleum ether extractables to be decreased. Soxhlet extraction and subsequent drying did not affect the NDF values of spinach, parsnips, cherries, or raspberries. The conservative use of heat as in Soxhlet extraction and subsequent drying did not consistently affect NDF values of the foods studied. |
