Flaxseed contains valuable nutritional composition with functional and bioactive properties. These characteristics make flaxseed an attractive source of functional ingredients for the preparation of foodstuffs. An extensive comparative study was conducted using raw and defatted flaxseed flours (DFF), investigating their functional properties, antioxidant potential (ABTS, DPPH, and FRAP assays), thermal properties by differential scanning calorimeter, microstructure by scanning electron microscope (SEM), and Fourier transformed infrared (FTIR) spectroscopic analysis. Flaxseed flour contains a considerable amount of cyanogen glycosides that have certain harmful effects on human health. Therefore, different processing methods (microwave processing, water boiling, autoclaving, soaking, solvent extraction, and ultrasound‐assisted detoxification) were compared to reduce this harmful compound in DFF. As seen in results, significant increase in proximate composition was observed in DFF. Similarly, DFF showed better antioxidant activity and functional properties. FTIR spectra revealed that the characteristic peaks associated with protein and carbohydrates were more prominent in DFF. Additionally, all tested detoxification methods significantly depleted HCN content. Among all, water boiling method found to be higher in reduction of HCN content followed by ultrasound assisted detoxification method. These findings revealed that DFF possess good nutritional, functional, and antioxidant properties, suggesting the potential application as a functional ingredient and as a supplement in foods.

原料和脱脂亚麻籽粉的结构和功能特性以及使用不同加工方法降解芥子油的含量

亚麻籽含有具有功能和生物活性的宝贵营养成分。这些特性使亚麻籽成为制备食品的功能成分的诱人来源。使用生和脱脂亚麻籽粉(DFF)进行了广泛的比较研究,研究了它们的功能特性,抗氧化潜力(ABTS,DPPH和FRAP分析),差示扫描量热仪的热性能,扫描电子显微镜(SEM)的微观结构和傅立叶变换红外(FTIR)光谱分析。亚麻籽粉中含有大量的氰苷,这些糖苷对人体健康具有一定的有害作用。因此,有不同的处理方法(微波处理,水煮沸,高压灭菌,浸泡,溶剂萃取,和超声辅助解毒比较以减少DFF中的这种有害化合物。从结果中可以看出,在DFF中观察到附近成分的显着增加。同样,DFF显示出更好的抗氧化活性和功能特性。FTIR光谱显示与蛋白质和碳水化合物有关的特征峰在DFF中更为突出。此外,所有测试的排毒方法均显着减少了HCN含量。其中,发现水煮法降低HCN含量更高,其次是超声辅助解毒法。这些发现表明DFF具有良好的营养,功能和抗氧化特性,表明其作为功能性成分和食品补充剂的潜在用途。在DFF中观察到近端成分的显着增加。同样,DFF显示出更好的抗氧化活性和功能特性。FTIR光谱显示与蛋白质和碳水化合物有关的特征峰在DFF中更为突出。此外,所有测试的排毒方法均显着减少了HCN含量。其中,发现水煮法降低HCN含量更高,其次是超声辅助解毒法。这些发现表明DFF具有良好的营养,功能和抗氧化特性,表明其作为功能性成分和食品补充剂的潜在用途。在DFF中观察到近端成分的显着增加。同样,DFF显示出更好的抗氧化活性和功能特性。FTIR光谱显示与蛋白质和碳水化合物有关的特征峰在DFF中更为突出。此外,所有测试的排毒方法均显着减少了HCN含量。其中,发现水煮法降低HCN含量更高,其次是超声辅助解毒法。这些发现表明DFF具有良好的营养,功能和抗氧化特性,表明其作为功能性成分和食品补充剂的潜在用途。FTIR光谱显示与蛋白质和碳水化合物有关的特征峰在DFF中更为突出。此外,所有测试的排毒方法均显着减少了HCN含量。其中,发现水煮法降低HCN含量更高,其次是超声辅助解毒法。这些发现表明DFF具有良好的营养,功能和抗氧化特性,表明其作为功能性成分和食品补充剂的潜在用途。FTIR光谱显示与蛋白质和碳水化合物有关的特征峰在DFF中更为突出。此外,所有测试的排毒方法均显着减少了HCN含量。其中,发现水煮法降低HCN含量更高,其次是超声辅助解毒法。这些发现表明DFF具有良好的营养,功能和抗氧化特性,表明其作为功能性成分和食品补充剂的潜在用途。
