The study which has been done in the ministry of health labs, Industrial Research and Testing center, labs belong to Directorate of supply in Damascus, and Department of Food Science at Faculty of Agriculture during February and march of 2017, aimed to determine the physiochemical properties of 10 flaxseed samples(A,B,C,D,E,F,G,H,I,J), (6 local from Hama, 2 Indian and 2 Egyptian).

The highest and lowest values were: moisture (3.45-4.306)%, fat (37.33- 41.99)%, protein (21.57-23.29)%, fibers (9.73-12.03)%, ash (3.466-4.26)% , carbohydrates (16.34-22.79)%, C16:0 (Palmitic acid)(4.98-7.027)%, C18:0 (Stearic acid)(3.87-5.05)%, C18:1 (oleic acid)(20.22-25.97)%, C18:2 (linoleic acid)(12.88- 15.08)%, C18:3 (linolenic acid)(49.046-53.71)%, total phenols (0.717-1.34)mg/g, water absorption (2.02-2.55)g/g, oil absorption (1.5-2.02)g/g, foam capacity (10.13-12.5)ml and foam stability (7.3-9.46)ml.

The local samples showed the highest values in: protein (in sample F), carbohydrates (A), C16:0 (D), C18:0 (E), C18:1 (C), foam capacity (F) and foam stability (F).

While the imported samples recorded the highest values in: moisture (in sample I), fat (J), fibers (G), ash (J) , C18:2 (I), C18:3 (J), total phenols (I), water absorption (in G), oil absorption (G).

The results showed that there were some significant differences between local samples and between local and imported ones.
