In this study, the effect of incorporating pasta regrinds with the flour used for producing of sapghetti was investigated .Experimental treatments were produced by mixing of flour with 0 (blank sample), 5,10,15,20,25,50 and 100 percent pasta regrinds, respectively. Spaghetti was produced in a semi-continuous process at Shiar Macaron Factory. Quality experiments such as cooking quality tests (determination of cooking loss percent and cooked weight) and sensory evaluation by trained test panel were the major tests that accomplished on products. The results of experiments showed that with increasing the amounts of regrinds, quality of spaghetti decreases but no considerable difference was observed between blank sample (0%) and with 5, and 10 percent treatments. Whereas further increase in regrind percent i.e. 15% and more, caused considerable reduction of final quality in spaghetti. Finally, the results of this study showed that addition upto 1-0% pasta regrinds has no adverse effect on final quality (obtained by sensory evaluation) and cooking quality of spaghetti.
