| 中文摘要: |
| 为了探讨菜籽清蛋白作为食品添加剂和蛋白强化剂的可能性，对从菜籽粕中提取的菜籽清蛋白进行主要成分分析和急性毒性试验。结果表明：相比于菜籽粕，超声辅助提取的菜籽清蛋白中的抗营养因子植酸、单宁和硫甙含量明显降低，蛋白质含量大幅提高，水分、灰分和粗脂肪含量有所降低；急性毒性试验结果初步表明菜籽清蛋白无毒，可考虑将其作为蛋白添加剂或营养强化剂应用于食品工业中。 |
| 英文摘要: |
| To explore the possibility of rapeseed albumin as a food additive and protein fortifier, main component analysis and acute toxicity test of rapeseed albumin extracted from rapeseed meal were carried out. The results showed that compared with rapeseed meal, the contents of anti-nutritional factors such as phytic acid, tannin and glucosinolate in rapeseed albumin extracted by ultrasound-assisted extraction significantly decreased, protein content increased greatly, and contents of moisture, ash and crude fat decreased to some extent. The acute toxicity test preliminarily showed that rapeseed albumin was nontoxic and could be considered as a protein additive or nutritional supplement used in the food industry. |
