Effects of cold plasma on chlorophylls, carotenoids, anthocyanins, and betalains

Food Res Int. 2023 May;167:112593. doi: 10.1016/j.foodres.2023.112593. Epub 2023 Feb 17.ABSTRACTPlasma is considered by several researchers to be the fourth state of matter. Cold plasma has been highlighted as an alternative to thermal treatments because heat induces less degradation of thermolabile bioactive compounds, such as natural pigments. In this review, we provide a compilation of the current information about the effects of cold plasma on natural pigments, such as the changes caused by plasma to the molecules of chlorophylls, carotenoids, anthocyanins, and betalains. As a result of the literature review, it is noted that can degrade cell membrane and promote damage to pigment storage sites; thereby releasing pigments and increasing their content in the extracellular space. However, the reactive species contained in the cold plasma can cause degradation of the pigments. Cold plasma is a promising technology for extracting pigments; however, case-by-case optimization of the extraction process is required.PMID:37087222 | DOI:10.1016/j.foodres.2023.112593
