Electrodialysis with ultrafiltration membrane (EDUF) is currently investigated at semi-industrial scale (560 cm2 of effective electrode surface) for the separation of bioactive cationic peptides. In this study, the focus was put on the impact of the initial whey protein hydrolysate (WPH) concentration, and the effect of current intensity have been tested. Experiments at 2%, 4% and 8% (w/v) WPH showed that a proportional relationship exists between the initial WPH concentration, and the quantity of peptides recovered. The cationic recovery fractions contained 16 peptides in similar amount as the previous work although including newly identified sequences. Thus, selectivity of the cationic recovery fraction was even improved. The working parameters used allowed obtaining a final 4.7% peptide yield after 6-h runs at 8% WPH. Aiming at nutraceutical applications built on the important ACE-inhibitory and DPP-IV inhibitory activities observed (6 times and 4 times higher than those of the initial WPH, respectively), two types of eco-efficiency scores were established based on those bioactivity values. Considering these scores, using the cationic recovery fractions as an antidiabetic product seems to be the most promising avenue. Preliminary results yielded by an experiment at higher current intensity are also very encouraging due to a barely increased environmental impact cost conjugated to a significantly higher peptide yield and preserved bioactivities. With all these new results, EDUF can be viewed as a promising industrial technology for the recovery of bioactive peptides in the perspective of ecoefficient strategies.

进料浓度与生物活性阳离子肽回收率之间的关系:对半工业规模 EDUF 生态效率的影响

超滤膜电渗析 (EDUF) 目前在半工业规模 (560 cm 2有效电极表面)用于生物活性阳离子肽的分离。在这项研究中,重点放在了初始乳清蛋白水解物 (WPH) 浓度的影响,并测试了电流强度的影响。在 2%、4% 和 8% (w/v) WPH 下的实验表明,初始 WPH 浓度与回收的肽量之间存在比例关系。阳离子回收部分包含 16 个肽,其数量与之前的工作相似,但包括新鉴定的序列。因此,甚至提高了阳离子回收部分的选择性。使用的工作参数允许在以 8% WPH 运行 6 小时后获得最终的 4.7% 肽产量。针对基于观察到的重要 ACE 抑制和 DPP-IV 抑制活性(分别是初始 WPH 的 6 倍和 4 倍)的营养保健应用,基于这些生物活性值建立了两种类型的生态效率评分。考虑到这些分数,使用阳离子回收部分作为抗糖尿病产品似乎是最有希望的途径。在较高电流强度下进行的实验所产生的初步结果也非常令人鼓舞,因为环境影响成本几乎没有增加,同时肽产量显着提高并保留了生物活性。凭借所有这些新结果,从生态效益战略的角度来看,EDUF 可以被视为回收生物活性肽的有前途的工业技术。根据这些生物活性值建立了两种类型的生态效率评分。考虑到这些分数,使用阳离子回收部分作为抗糖尿病产品似乎是最有希望的途径。在较高电流强度下进行的实验所产生的初步结果也非常令人鼓舞,因为环境影响成本几乎没有增加,同时肽产量显着提高并保留了生物活性。凭借所有这些新结果,从生态效益战略的角度来看,EDUF 可以被视为回收生物活性肽的有前途的工业技术。根据这些生物活性值建立了两种类型的生态效率评分。考虑到这些分数,使用阳离子回收部分作为抗糖尿病产品似乎是最有希望的途径。在较高电流强度下进行的实验所产生的初步结果也非常令人鼓舞,因为环境影响成本几乎没有增加,同时肽产量显着提高并保留了生物活性。凭借所有这些新结果,从生态效益战略的角度来看,EDUF 可以被视为回收生物活性肽的有前途的工业技术。在较高电流强度下进行的实验所产生的初步结果也非常令人鼓舞,因为环境影响成本几乎没有增加,同时肽产量显着提高并保留了生物活性。凭借所有这些新结果,从生态效益战略的角度来看,EDUF 可以被视为回收生物活性肽的有前途的工业技术。在较高电流强度下进行的实验所产生的初步结果也非常令人鼓舞,因为环境影响成本几乎没有增加,同时肽产量显着提高并保留了生物活性。凭借所有这些新结果,从生态效益战略的角度来看,EDUF 可以被视为回收生物活性肽的有前途的工业技术。
