| Abstract: |
| In order to improve the nutrient content of grapefruit seed oil and develop high-quality safe oil, Meizhou grapefruit seed was taken as the research object, and the change rule of grapefruit seed oil quality in the process of germination was studied. The results showed that the oil yield of grapefruit seed decreased gradually with the prolonging of germination time. After germination for 9 d, the oil yield of grapefruit seed was (52.18±001)%, which was 3.56 percentage points lower than that without germination. The fatty acid composition of grapefruit seed oil unchanged during germination, and the content of oleic acid increased slightly, while both the contents of linoleic acid and linolenic acid decreased slightly. The acid value and peroxide value of grapefruit seed oil after germination for 5 d were (1.19±004) mgKOH/g and (1.98±0.02) mmol/kg, which met the national standards of vegetable oil. The contents of fat-soluble nutrients tocopherol and squalene increased first and then decreased, and the contents of tocopherol and squalene after germination for 5 d were (265.29±0.05) μg/g and (36.10±0.01) μg/g, which reached the maximum value and increased by 3.74 times and 7.60 times compared with ungermination, respectively. Therefore, short-term germination can improve the nutritional value of grapefruit seed oil. |
