Abstract

Brewer's Spent Grain (BSG) is a by-product of the brewing industry, rich in dietary fibers that offer various health benefits. This review delves into the molecular and structural transformations of BSG and dietary fibers (arabinoxylan, beta-glucan, cellulose etc.) extracted from BSG, triggered by recent advancements in extraction technologies. Through an analysis of current methodologies, such as advanced solubilization methods and emerging technologies like ultrasonication, this paper discusses their significant improvement in yield of BSG-dietary fiber and impact on the structural and functional properties of BSG-dietary fibers (BSG-DF). The review highlights how these technologies enhance fiber solubilization and modify physicochemical properties, thereby improving their functionality in food applications. Furthermore, the review aims to bridge gaps in current research and suggest future directions for optimizing extraction processes to better exploit these fibers in the food industries.

综述：研究现代提取技术对啤酒糟膳食纤维中纤维素和半纤维素的功能和结构特性的影响

啤酒糟（BSG）是酿造业的一种副产品，富含膳食纤维，具有多种健康益处。本综述深入探讨了 BSG 和从 BSG 中提取的膳食纤维（阿拉伯木聚糖、β-葡聚糖、纤维素等）的分子和结构转变，这些转变是由近期提取技术的进步所引发的。本文通过分析当前的方法，如先进的增溶方法和超声波等新兴技术，讨论了这些方法对 BSG-膳食纤维产量的显著提高以及对 BSG-膳食纤维（BSG-DF）结构和功能特性的影响。综述重点介绍了这些技术如何提高纤维增溶和改变理化特性，从而改善其在食品应用中的功能。此外，该综述还旨在弥补当前研究的不足，并提出优化提取工艺的未来方向，以便在食品工业中更好地利用这些纤维。

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
