With the extension of heat processing, the oxidation and formation of harmful substances in oils appeared. The effect of the high-temperature stages (180 °C, four stages I, II, III, and IV were divided according to the heating-up period) on the fatty acid profile, the thermal properties, the composition of total polar compounds, and the physicochemical properties of rapeseed oil (RSO) were investigated. As the heating processing, carnosic acid (CA) significantly reduces the peroxide value, p-anisidine value, trans-fatty acid, the action of alkyl radicals, and the formation of oxidized triglyceride monomers (Ox-TGM).

- - The study examined Ziziphi Spinosae Semen, a Chinese herbal medicine, for aflatoxin contamination and identified fungi responsible for it by analyzing 32 samples from different processing stages using specialized methods.
- - Aflatoxins were found in 28 samples, with the highest contamination from washing, exceeding safety limits set by the Chinese Pharmacopoeia; specifically, aflatoxin B1 was present in three samples.
- - Fungal contamination increased through processing, particularly due to composting and washing, with Aspergillus flavus identified as the main source of aflatoxins, emphasizing the need for monitoring during production.
