This study aimed to investigate the possibility of utilizing oat by-products for fiber preparation. Oat husk (OH) and oat bran (OB) were micronized and used to prepare a novel product rich in fiber and with enhanced antioxidant properties. The basic chemical composition and phenolic acid profile were determined in OH and OB. The antioxidant properties of OH and OB were also analyzed. The type and strength of interactions between the biologically active compounds from their mixtures were characterized by an isobolographic analysis. The analyses showed that the sum of phenolic acids was higher in OH than in OB. Ferulic acid was dominant in both OH and OB; however, its content in OH was over sixfold higher than that in OB. The results also suggested that both OH and OB can be used for preparing fiber with enhanced antioxidant properties. The optimal composition of the preparation, with 60-70% of OH and 30-40% of OB, allows for obtaining a product with 60-70% fiber and enhanced antioxidant activity due to bioactive substances and their synergistic effect. The resulting product can be a valuable additive to various food and dietary supplements.
本研究旨在探讨利用燕麦副产品制备纤维的可能性。对燕麦壳（OH）和燕麦麸（OB）进行了微细化处理，并将其用于制备一种新型的富含纤维且具有增强抗氧化性能的产品。测定了 OH 和 OB 的基本化学成分和酚酸组成。还分析了 OH 和 OB 的抗氧化性能。通过等立体分析，对其混合物中生物活性化合物之间的相互作用类型和强度进行了表征。分析表明，OH 中的总酚酸含量高于 OB。阿魏酸在 OH 和 OB 中均占主导地位；然而，其在 OH 中的含量是 OB 中的六倍多。结果还表明，OH 和 OB 均可用于制备具有增强抗氧化性能的纤维。制备物的最佳组成，60-70%的 OH 和 30-40%的 OB，可获得 60-70%纤维和增强的抗氧化活性的产物，这归因于生物活性物质及其协同作用。所得产品可作为各种食品和膳食补充剂的有价值的添加剂。
