The late 1970s was the onset of literature about the first research outputs on alternatives to create added-value to agro-food byproducts focused on the reduction of the dependency on raw materials and, simultaneously, helping to reduce the environmental impacts of the agricultural activities. This trend, increased over the years and during the past decade, has been boosted by the growing concern of the socio-economic impact of wastes from agro-food activities, however, with little success of the proposed applications. Throughout four decades an array of studies have emerged, aimed to gain evidence on the relevance of innovation in the agro-food industry, as well as to overcome this situation. To our knowledge, only a few cases, summarized in the present perspective, represent the main alternatives currently available for the valorization of agro-food byproducts, with indications of some constraints that need to be addressed, in the coming years, to obtain a real profit from these products.

从四个十年来实现农业食品副产品价格平衡的漫长梦想中醒来：朝着获得的知识的实际应用迈进

1970年代末期是关于替代品的第一项研究成果的文献的开始，这些替代品旨在为农业食品副产品创造增值，其重点是减少对原材料的依赖，同时有助于减少农业活动对环境的影响。在过去的十年中，这种趋势在过去十年中有所增加，但由于人们越来越关注农业食品活动产生的废物对社会经济的影响，因此这种趋势得到了加强，但是所提出的申请却很少成功。在过去的四十年中，出现了一系列研究，旨在获得有关农业食品工业中创新的相关性的证据，并克服这种情况。据我们所知，从目前的角度来看，只有少数情况，
