摘要

This research reported the effect of peeling naked oats with a peeling machine equipped with the flexible alloy blade.Results showed that the flexible alloy blade could achieve the same effect as traditional abrasive rolls. Furthermore, the new peeling method had hardly damage to the oat kernels. The result of scanning electron microscopy indicated the surface of peeled naked oats by the flexible alloy blade is homogeneous. The gap between the flexible alloy blade and the slotted screen could change the particle sizes of the flours obtained, which differed from traditional peeling machines. In addition, peeling for 15 seconds significantly reduced the microbial contaminants. The removal of outer layer decreased the lipase activity. The technological parameters were optimized by orthogonal L9（34） test, the results showed a 30 s peeling time and 2% second-addition of water contributed to the peeling rate. The texture analysis demonstrate that the hardness of cooked groats decreases obviously after peeling treatments.
