In Mexico, whey is discarded into drains without treatment, which represents an environmental problem. It is known that whey is a mixture of nutrients that increase biochemical demand (BOD) and chemical oxygen demand (COD), exceeding the limits established by national and international standards. Some uses of whey have been proposed to reduce the negative impact it produces on the environment. Some of these uses are the production of high‐value raw materials, separation of macromolecules of industrial interest, and the generation of energy, among others. The integral use of waste under a biorefinery scheme represents a viable alternative for the use of this waste. In this way, the chemical composition of the waste can be used to recover compounds with high added value. The main objective of this review is to propose a dairy whey biorefinery to use components of commercial interest. This biorefinery process involves three stages: the first is the separation of lactoferrin using a polyacrylamide matrix (PAM) impregnated with copper; the second is lactic fermentation using the residue resulting from the separation of lactoferrin, from which lactic acid, hydrolyzed proteins, and probiotics will be obtained. Finally, in the third stage, the residue from the previous stage can be used to generate biogas. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

使用生物精炼厂对乳清进行增值

在墨西哥,乳清未经处理就被丢弃到排水沟中,这是一个环境问题。众所周知,乳清是营养物质的混合物,会增加生化需求(BOD)和化学需氧量(COD),超过国家和国际标准所确定的限制。已经提出了乳清的一些用途,以减少其对环境产生的负面影响。其中一些用途是高价值原材料的生产,具有工业意义的大分子的分离以及能源的产生。在生物精炼厂计划中废物的综合利用是使用这种废物的可行替代方案。这样,废物的化学成分可用于回收具有高附加值的化合物。这篇综述的主要目的是提出一种乳清乳清生物精炼厂,以使用具有商业意义的成分。该生物精炼过程涉及三个阶段:第一阶段是使用浸渍有铜的聚丙烯酰胺基质(PAM)分离乳铁蛋白;第二种方法是乳酸发酵,它使用分离乳铁蛋白的残渣进行发酵,由此可得到乳酸,水解蛋白和益生菌。最后,在第三阶段中,前一阶段的残留物可用于产生沼气。©2020年化学工业协会和John Wiley&Sons,Ltd 第二种方法是乳酸发酵,它使用分离乳铁蛋白的残渣进行发酵,由此可得到乳酸,水解蛋白和益生菌。最后,在第三阶段中,前一阶段的残留物可用于产生沼气。©2020年化学工业协会和John Wiley&Sons,Ltd 第二种方法是乳酸发酵,它使用分离乳铁蛋白的残渣进行发酵,由此可得到乳酸,水解蛋白和益生菌。最后,在第三阶段中,前一阶段的残留物可用于产生沼气。©2020年化学工业协会和John Wiley&Sons,Ltd
