Abstract This study entitled “Pulverized Crab Shell Flour as a Potential Substitute for The Commercial Flour” has aimed to determine on the effectiveness of Crab Shell as a substitute for flour. The Researchers want to compare the similarities and differences of the Nutritive Value and Acceptability Level (taste‚ odor/aroma‚ color‚ texture) of Pulverized Crab Shell Flour and Commercial Flour. They used two set up. In set A‚ Pulverized Crab Shell Flour and in set B‚ Commercial Flour. After
