In addition, thyme extract can also inhibit the reproduction of bacteria during the cold storage of Chinese sausages.

★ Antioxidant effect

Thyme methanol extract has one of the strongest antioxidant activities among all the wild plant extracts collected. The antioxidant capacity of thyme aromatic oil added to 1200mg/kg was close to that of 200mg/kg dibutyltoluene (BHT), and it did not affect the color and smell of soybean oil. Taking the scavenging effect of diphenylpichydrazine free radicals (DPPH) as an index, the evaluation results of the antioxidant effects of 16 kinds of thyme volatile oils showed that among these 16 kinds of plants, thyme volatile oils had moderate antioxidant effects. Thyme extract also has a certain anti-fat oxidation effect. Studies have shown that Thymus vulgaris L. has stronger antioxidant activity than known antioxidant vitamin E and BHT.
