The use of synthetic additives is one of the main approaches for preventing microbial growth and oxidative reactions in meat products. These preservatives were recently marked as unhealthy to humans; therefore, the consumers demand for fresh, natural, and negligibly processed products with lower content of artificial additives is increasing.

Experimental:  

The effect of Satureja bachtiarica Bunge essential oil (EO) and tomato powder (TP) to optimize sausage formulation with reduced nitrite content was investigated. Response surface methodology (RSM) was used to investigate the effects of different levels of EO (200-400 ppm), TP (5-15%) as Hurdles, and sodium nitrite (SN) (0-300 ppm) in sausage formulation during storage (0- 24 days). Dependent variables including residual nitrite, pH, color indices, microbial load, and hardness were investigated and finally model optimization and validation were conducted.

The results showed that residual nitrite was strongly depending on initial added nitrite and storage time (p<0.001), so the use of nitrite substituent was undeniable to have an improved sausage formulation without microbial defect. RSM represented a quadratic model for all responses except in texture which was linear and the pH and microbial load showed interaction. The optimized predicted values for SN, EO and TP were 56 ppm, 378 ppm and 5%, respectively. The model validation revealed that the results of the experiments were in good agreement with the predicted values.

Recommended applications/industries:

 The results of the present study can be useful for consideration in meat products industry to reduce the nitrite level in sausage formulation.

Due to the unfavorable side effects of some commonly used chemical drugs, the trend in the public has shifted towards using herbal medicines to treat central nervous system disorders like depression. The present experimental study was designed to evaluate the effect of Marze (Satureja bachtiarica Bunge) essential oil on reserpine-induced depression in rats.
In total, 48 male Wistar rats were randomly divided into 6 groups: 1) control, 2) reserpine, 3-5) reserpine with 50, 75 and 100 mg/kg of Marze essential oil, respectively, and 6) reserpine and fluoxetine. The forced swimming test was used to evaluate the antidepressant activity of the essential oil. Total antioxidant capacity (TAC) and MDA levels of serum and brain were also determined.
Reserpine induced a significant increase in the immobility time of rats in the forced swimming test (P=0.02) and treatment with Marze essential oil (50, 100 mg/kg) ameliorated the reserpine induced changes (P=0.04, P=0.03, respectively). Reserpine-induced reduction in brain TCA was improved using Marze essential oil at a dose of 100 mg/kg (P=0.04). Marze essential oil at 100 mg/kg dose significantly decreased the MDA level in the brain tissues of reserpine-treated rats (P=0.04).
Marze (Satureja bachtiarica Bunge) essential oil has the ability to prevent depression induced by reserpine probably via its antioxidant activity.

Cervical cancer is the most common   female genital cancer and the second most common cancer in women in the   world. Since the herbal ingredients have been used for centuries to treat   cancer, purpose of the present study was to determine the cytotoxic   effect of hydroalcoholic extract from Satureja bachtiarica Bungeon   Hela cancer cells line. Hela cells line and natural fibroblast cells line were cultured in RPMI 1640 and DMEM Containing fetal bovine serum and antibiotics, respectively. The cells were exposed to different doses of hydroalcoholic extract of Satureja bachtiarica Bunge (0.156, 0.312, 0.625, 1.25, and 2.5 mg/ml) and were incubated for 24, 48 and 72 hr, respectively. After the incubation period, the modified MTT colorimetric test was used in order to determine cell toxicity of the extract. The results of MTT test Showed that hydroalcoholic extract of Satureja bachtiarica Bunge has dose-dependent anti-cancer effect on Hela cancer cells, so that by increasing the concentration of extract and incubation in 72h, the most percentage of cell death was observed (p < 0.05). The extract of plant didn’t show any significant cytotoxicity on natural fibroblast cell line. Therefore, it seems that its compounds will be applied in treating cancer through more researches. Considering the low side effects of herbal medicines, especially antioxidants including Satureja bachtiarica Bunge can be used to treat cancer with drug therapy.

Satureja bachtiarica Bunge, an endemic species with relatively wide distribution, is traditionally used as a medicinal and spice plant in Iran. Essential oils composition, antioxidant activities and phenolics content of wild and cultivated S. bachtiarica of Yazd origin were determined in this study. Hydrodistilled essential oils were analyzed by GC-FID and GC-MS. Folin-Ciocalteu and AlCl3 methods were served to determine total phenolics and flavonoids of methanol extracts, respectively. Antioxidant activities of the extracts were examined by DPPH and FRAP methods and their rosmarinic acid content was measured by using HPLC. The oil content of cultivated and wild plants was 1.8% and 0.9% v/w, respectively. Oxygenated monoterpens (78.3 - 79.5%) constituted the major fraction of essential oils with carvacrol (71.4% and 57.4% in cultivated and wild plants, respectively. p - Cymene (8.6 - 12.5%) was another major components of essential oils. Methanol extract from wild growing plants exhibited the higher levels antioxidant activities in both DPPH and FRAP methods (29.04 and 58.25 mg Trolox/g, respectively). This extract also contained the higher amounts of total phenolics (24.5 mg caffeic acid /g sample), total flavonoids (87.99 mg catechin /g sample) and rosmarinic acid (3.73 mg/g dry weight) in comparison to cultivated ones (16.2 mg caffeic acid /g sample, 40.55 mg catechin /g sample and 1.73 mg/g dry weight, respectively). Obtained results may be helpful for domestication of this plant and development of natural antioxidants for use in different industries.
