阿拉伯木聚糖(AXs)是具有高营养价值和适用性的化合物,包括益生元或补充成分,在食品制造业。不幸的是,AXs的回收可能需要先进的分离和集成策略。这里,讨论了从谷物及其副产品中提取AXs的新兴技术的分析。这篇综述涵盖了过去2-3年实施的不同方法,确定方法的类型,提取源,AX理化性质和预处理条件是影响回收率的主要因素。碱性提取是目前最常用的方法之一,主要是由于其简单和高回收率。同时,及时审查了在食品应用中应用的回收AXs,例如潜在的面包成分,作为益生菌封装的壁材,在啤酒和非酒精饮料制造中,烘焙产品和饼干中的补充成分,中国面条的改良剂,用于输送平台的3D食品打印和纳米结构设计。
Arabinoxylans (AXs) are compounds with high nutritional value and applicability, including prebiotics or supplementary ingredients, in food manufacturing industries. Unfortunately, the recovery of AXs may require advanced separation and integrated strategies. Here, an analysis of the emerging techniques to extract AXs from cereals and their by-products is discussed. This
review covers distinct methods implemented over the last 2-3 years, identifying that the type of method, extraction source, AX physicochemical properties and pre-treatment conditions are the main factors influencing the recovery yield. Alkaline extraction is among the most used methods nowadays, mostly due to its simplicity and high recovery yield. Concurrently, recovered AXs applied in food applications is timely reviewed, such as potential bread ingredient, prebiotic and as a wall material for probiotic encapsulation, in beer and non-alcoholic beverage manufacturing, complementary ingredient in bakery products and cookies, improvers in Chinese noodles, 3D food printing and designing of nanostructures for delivery platforms.
