| Abstract: |
| The elemental library and nutrient composition of donkey fat were studied. The quality indexes of donkey oil extracted and separated from donkey fat were determined. The 37 metal elements in donkey fat were scanned and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that all the metal elements in donkey fat were not detected. The main components of donkey fat samples were scanned by multi-mass analyzer combined with mass spectrometer at MSn level. It was found that there were 16 kinds of amino acids and their derivatives, 11 kinds of organic acids and 46 kinds of lipids. In addition, there were many ingredients such as carbohydrates and vitamins. The physicochemical properties of donkey oil extracted by ultrasound-assisted solvent were determined as follows: relative density 0.908, moisture content 0.68%, acid value 0.58 mgKOH/g, peroxide value 0.018 g/100 g, iodine value 85 gI/100 g. The effect of storage temperature on peroxide value of donkey oil were studied. The results showed that donkey oil could be stored at room temperature. Donkey oil could be used as research and development materials for food and cosmetics, and had broad application prospects. |
