"Starch fragmentation in relation to processing conditions ... Characterization of the fragmented starch occurring during milling is presented. Depending on processing conditions, the average molecular weight of the branched polymer was 1.5 × 10 6 to 1.1 × 107 Da. Resulting starch fragmentation was shown to strongly impact bowl life and overall sensory quality of the finished corn flakes.
Cement Industry Overview - Portland Cement Association The domestic cement industry is regional in nature. The cost of shipping cement prohibits profitable distribution over long distances. As a result customers traditionally purchase cement from local sources. Nearly 98 percent of U.S. cement is shipped to its customers by truck. Barge and rail modes account for the remaining distribution modes.
