Second interim report of the A.O.A.C.-A.O.C.S. Crude Fiber Liaison Committee

Conclusions The results obtained in this collaborative study show that none of the methods tested offer sufficient advantages in precision and accuracy to warrant selection as an official method to the exclusion of other methods studied. Also the precision of all methods tested show these methods to be inadequate for checking crude fiber specification limits set up by the N.S.P.A. on soybean oil meal. This statement would also apply to any other product where specification limits on crude fiber are narrower than the precision shown in Table VI. Ease and speed for manipulation are also an important criterion for choosing an official method. A poll of committee members showed no definite preference for any one method studied; every method received the support of two or more of the committee members. The Liaison Committee is still hopeful that a method can be devised that will give a precision in line with trade specifications and practices. The committee will continue to work toward the development of such a method.
