摘要:

本研究旨在为探索双螺杆挤压膨化技术对小麦麸皮及其在馒头中的应用潜力,以期开发出兼具优良品质和营养价值的含麸馒头。通过以‘徐麦44’小麦为原料,将经过双螺杆挤压膨化处理的麸皮回添至馒头中,利用质构仪、扫描电子显微镜(SEM)和气相色谱-质谱联用(GC-MS)等技术,对不同处理方式下馒头样品的理化、感官及营养品质进行了深入评估。研究结果表明,与添加未膨化麸皮的馒头相比,添加膨化麸皮的馒头在蓬松度、色泽、弹韧性、食味性和适口性等各项感官指标上均表现出显著优势,最终获得了86.9分。膨化改性后的麸皮显著改善了馒头的微观结构,赋予了其更佳的弹性、咀嚼性,使得馒头食用起来更加劲道爽口。此外,挤压膨化技术还显著提升了含麸馒头的风味多样性,检出了46种烘烤香气相关的挥发性化合物,并使其膳食纤维含量达到5.65%。综上所述,双螺杆挤压膨化技术能够有效提升麦麸回添馒头的感官品质、营养价值和风味特征,证明了膨化改性后的麸皮是一种极具潜力的膳食纤维补充原料,为麸皮的高值化利用提供了强有力的技术支持。

Abstract:

This study aimed to investigate the effects of twin-screw extrusion puffing technology on wheat bran and bran-containing steamed bread, with the goal of developing steamed bread products with nutritional value and improved quality. Extruded-puffed bran was added back into steamed bread made from Xumai 44 flour. Various analytical techniques, including texture analyzer, SEM, and GC-MS, were employed to evaluate the physicochemical properties, sensory, and nutritional qualities of the different steamed bread samples. The results showed that steamed bread with extruded-puffed bran exhibited superior fluffiness, color, springiness and toughness, palatability, and overall eating quality compared to that with untreated bran, achieving a sensory score of 86.9. In contrast to the steamed bread with untreated bran, the puffed-bran-supplemented bread not only displayed a more intact microstructure but also demonstrated significantly enhanced springiness and chewiness, resulting in a firmer and more refreshing mouthfeel. Furthermore, the extrusion puffing technology also significantly improved the flavor diversity of bran-containing steamed bread, detected 46 kinds of baking aroma-related volatile compounds, and made its dietary fiber content reach 5.65 %. In summary, extrusion puffing technology effectively improved the sensory, nutritional value, and flavor qualities of bran-back-added steamed bread. The puffed-modified bran represents a more promising raw material for dietary fiber supplementation.
