In order to get the shear mechanical properties of flaxseed, the Texture Analyzer was used to study the shear properties of flaxseed. First flaxseeds were dried, and then the effect of moisture content and loading rate on shear mechanical properties was studied. The results showed the curve of drying time and moisture content was established. The maximum shear force of flaxseed was between 10.43 N and 12.55 N, and the shear power was 2.277 mJ to 3.677 mJ. Under the same loading rate, shear force and shear power of flaxseed with different moisture content had a difference. The analysis of variance show that the moisture content has a significant impact on the maximum shear force and the shear power(P<0.05). And the loading rate does not indicate a significant impact (P>0.05).
