Abstract

In this research, ultrasound-assisted extraction (UAE) coupled with response surface methodology was used to identify the optimal process parameters (temperature, time, and solvent composition (ethanol-water ratio)) for bioactive compounds extraction from stalks and debranning products. Extraction efficiency was assessed in terms of total phenolic compounds (TPCs) and antioxidant activity (AA), and phenolic profiles were identified using HPLC-DAD for the four samples of byproducts (two samples from stalks, C1 and C2, and two samples for debranning products, C3 and C4, from two different farms). The optimized extract containing the highest amount of TPC at different levels was used to enrich bread to evaluate the ability of extending their shelf life using a hyperspectral imaging device (935-1720 nm). Under the optimal conditions, the amounts of phenolics on average in stalk increased by about 79.5% and 47.0% in debranning products, whereas the relative AA increased by about 28.5% (C1 and C2 samples) and 63.0% (C3 and C4 samples) when UAE was applied with respect to the traditional technique. The characterization of stalk phenolic acids profile revealed that gallic, ferulic, and 4-coumaric acids were the prevalent ones. Otherwise, caffeic, syringic, and 3-coumaric acids were the most abundant in debranning products. As expected, enriched bread showed a significant increase in TPC and AA values without influence on organoleptic characteristics. Finally, enriched bread showed a shelf-life increase of about five days.

高粱副产品中酚类物质的提取:升级回收策略及食品应用。
在本研究中,采用超声辅助提取(UAE)结合响应面法确定了从秸秆和去皮产物中提取生物活性化合物的最佳工艺参数(温度、时间和溶剂组成(乙醇-水比))。以总酚类化合物(TPCs)和抗氧化活性(AA)为指标评价了提取效率,并利用HPLC-DAD对4个副产物样品(2个秸秆样品C1和C2, 2个去皮产品样品C3和C4,来自两个不同的农场)进行了酚类分析。利用高光谱成像装置(935 ~ 1720 nm),对不同含量的TPC含量最高的最佳提取液进行面包发酵,评价其延长面包保质期的能力。在最优条件下,脱皮产物中酚类物质的平均含量比传统脱皮工艺分别提高了79.5%和47.0%,相对AA含量分别提高了28.5% (C1和C2)和63.0% (C3和C4)。秸秆酚酸谱分析表明,未食子酸、阿魏酸和4-香豆酸是主要的酚酸。此外,咖啡酸、丁香酸和3-香豆酸在去皮产品中含量最多。正如预期的那样,营养丰富的面包在不影响感官特性的情况下显著增加了TPC和AA值。最后,营养丰富的面包的保质期延长了大约5天。

期刊介绍: Antioxidants (ISSN 2076-3921), provides an advanced forum for studies related to the science and technology of antioxidants. It publishes research papers, reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
