Hydrolysis oxidation

Most plastics do not biodegrade readily, however, they do still degrade in the environment because of the effects of UV-light, oxygen, water and pollutants. This combination is often generalised as polymer weathering. Chain breaking by weathering causes increasing embrittlement of plastic items, which eventually causes them to break apart. Fragmentation then continues until eventually mic… WebThere are two important pathways leading to rancidity: oxidation and hydrolysis (Robards et al., 1988). Oxidation leads to oxidative rancidity and is the result of oxygen attacking glycerides. Oxidation can be initiated by heat, pro-oxidants, certain enzymes (lipoxygenases) or light (Robards et al., 1988).
