Waste in the food industry is characterized by a high ratio of product-specific waste. Not only does this mean that the generation of this waste is unavoidable, but also that the amount and kind of waste produced, which consists primarily of the organic residue of processed raw materials, can scarcely be altered if the quality of the finished product is to remain consistent. The utilization and disposal of product-specific waste is difficult, due to its inadequate biological stability, potentially pathogenic nature, high water content, potential for rapid autoxidation, and high level of enzymatic activity. The diverse types of waste generated by various branches of the food industry can be quantified based on each branches' respective level of production. Moreover; the origins of each type of waste and a tabulated overview of the traditional agricultural methods for reusing the waste are discussed. Additionally, alternative methods of waste management have emerged, which target the most important contents of the waste. In conclusion, new possibilities for the utilization of food industry waste are described.
食品工业中的废弃物具有特定产品废弃物比例高的特点。这不仅意味着这种废弃物的产生不可避免,而且还意味着,如果要保持成品质量一致,那么所产生的废弃物的数量和种类(主要由加工原料的有机残渣组成)几乎无法改变。由于特定产品废弃物的生物稳定性不足、具有潜在致病性、含水量高、有快速自动氧化的可能性以及酶活性水平高,其利用和处置都很困难。食品工业各分支产生的不同类型的废弃物可以根据各分支各自的生产水平进行量化。此外,还讨论了每种废弃物的来源以及传统农业再利用废弃物方法的列表概述。此外,已经出现了针对废弃物最重要成分的替代废弃物管理方法。总之,描述了食品工业废弃物利用的新可能性。
