| Abstract: |
| With eleven different varieties of walnuts from four main production areas in Xinjiang as raw materials, the contents of water and crude fat in walnut kernels after shelling were analyzed, and the acid value, peroxide value and fatty acid composition of the pressed walnut oils were analyzed. The results showed that the contents of crude fat and water in walnut kernels of eleven different varieties were 4909%-68.95% and 2.12%-3.10%, respectively. The acid value and peroxide value of pressed walnut oils were 0.26-0.51 mgKOH/g and 0.12-3.27 mmol/kg, all of which were within the range of quality indicators required by the national standard. The fatty acid composition in walnut oil was dominated by unsaturated fatty acids, in which the content of oleic acid was 14.42%-31.46%, the content of linoleic acid was 50.49%-62.78%, and the content of linolenic acid was 9.56%-14.69%. |
