Summary: Enzymatic and nonenzymatic oxidation of linoleic (LA) and alpha-linolenic acid (ALA) during pressing and storage of plant oils leads to the formation of various oxylipins. The concentrations of oxylipins are found to be correlated with the peroxide value (PV) of the oils, while secondary volatile aldehydes do not show similar correlations. Comprehensive analysis of different types of hydroxy-, epoxy-, and dihydroxy-LA/-ALA provides new insights into the composition of plant oils and ongoing oxidation processes.

Summary: Biodegradable plastic mulches (BDMs) have the potential to be an eco-friendly alternative to conventional plastic mulches in agriculture. However, their long-term impacts on soil ecosystems are still uncertain, and further research is needed. Incorporating BDMs into the soil may stimulate microbial activity, but there is also a risk of incomplete degradation and release of residual microplastics and additives.
