Linoleic acid contained in sunflower seed oil is an essential fatty acid for human body. It constitutes the basic component of various cells. It can regulate metabolism, maintain blood pressure balance and reduce blood cholesterol. Sunflower seed oil contains trace phytol and phospholipid, which can prevent the increase of serum cholesterol. The carotene contained in sunflower seed oil can be converted into vitamin A after being absorbed by human body, which can prevent night blindness, dry skin and other diseases, and has an anti-cancer effect. At the same time, sunflower seed oil is light and transparent and can retain the flavor of natural food when cooking, and its smoke point is also very high, which can avoid the harm of lampblack to human body.

A charcoal grilled chicken is prepared by using the following grilling method:
Step 1: chicken was cut into strips with a thickness of 1 cm and soaked for 1 h in soaking solution at 4° C.; each 1000 mL of soaking solution included 8 mL of edible vinegar, 1 g of baking soda in the solvent of water; the soaking ratio of chicken in the soaking solution was 1000 g/1000 mL; the pH of the soaking solution was 3.3; the soaked chicken was evenly dispensed into boxes with sealing covers, sunflower seed oil was added into the boxes and sealed, the ratio of sunflower seed oil to the weight of chicken was 50 mL/1000 g;
Step 2, the chicken in Step 1 was subjected to plasma treatment; the specific method was that the sealed chicken was placed in high-voltage electric field cold plasma non-thermal sterilization equipment, treatment parameters are set as an electrode gap being 4.0 cm, the voltage of the high-voltage electric field being 80 kV, and discharging time being 180 s.
Step 3, chicken treated by plasma was grilled on the stainless-steel grill; the specific method was that solid alcohol blocks were used to ignite charcoal fire; after the open fire of all the charcoal was ended, the sample meat was put on the grill which is far away from the fire source by 5 cm; the meat was turned over every 2 min; when the grilling time was 12 min, the internal temperature of the sample was measured with a probe thermometer; when the internal temperature reached 75° C., the grilling was stopped; when the internal temperature did not reach 75° C., grilling was continued, until the internal temperature reached 75° C.; when the internal temperature reached 75° C., the surface temperature of charcoal fire at the moment was measured using an infrared thermometer, and the surface temperature of charcoal fire was kept to be 180˜220° C.

The meat used in all the above examples and comparative examples is the same raw chicken breast purchased in the same batch.
The contents of polycyclic aromatic hydrocarbons in grilled chicken prepared in the above examples 1˜9 and comparative example 1 were measured: the measurement method of polycyclic aromatic hydrocarbons refers to GB 5009.265˜2016 method 1 National Food Safety Standard: Measurement Method of Polycyclic Aromatic Hydrocarbons in Food.
Table 1 shows the contents of several polycyclic aromatic hydrocarbons (PAHs) in the charcoal grilled chicken prepared by the above examples and comparative example. Table 2 shows variations of content of polycyclic aromatic hydrocarbons in different examples and comparative examples.
The generation of polycyclic aromatic hydrocarbons (PAHs) in grilled food is largely because of pyrolysis, oxidation and cyclization of oils and fats in the food system. In the open fire grilling process, the oil is leached from the meat and dripped onto the burning charcoal fire and wood. The smoke generated by combustion of oil and heat source adheres to the surface of the meat, which may cause considerable pollution. Therefore, antioxidant capacity and fatty acid composition (unsaturation degree) of grilling oil have a significant impact on the generation of polycyclic aromatic hydrocarbons (PAHs) in grilled meat. Compared to examples 1, 2 and 3, It is shown that under the condition that the amounts of edible oil are the same during the grilling process, different kinds of edible oils have significant influence on the content of polycyclic aromatic hydrocarbons (PAHs) in charcoal grilled chicken. Compared to rapeseed oil in example 2 and soybean oil in example 3, sunflower seed oil in example 1 can significantly reduce the content of polycyclic aromatic hydrocarbons in charcoal grilled chicken; compared to example 1 and comparative example 1, it can be seen that compared to comparative example 1 in which edible oil is not added, the use of sunflower seed oil in grilling process not only does not increase the content of polycyclic aromatic hydrocarbons, but also effectively reduces the content of Benzo(b)fluoranthene. Therefore, the sunflower seed oil adopted in the disclosure can effectively control the content of polycyclic aromatic hydrocarbons in charcoal grilled meat.
Compared to examples 3 and 4, it can be seen that on the premise of the same edible oil variety, the chicken is first soaked with the soaking solution of the disclosure in the process of grilling, which can significantly reduce the content of polycyclic aromatic hydrocarbons in the charcoal grilled meat.
Compared to examples 3 and 5, it can be seen that on the premise of the same edible oil variety, the sealed chicken is first treated with plasma in the process of grilling, which can significantly reduce the content of polycyclic aromatic hydrocarbons in the charcoal grilled meat.
Compared to examples 1 and 6 as well as examples 2 and 7, it can be seen that when edible oil uses sunflower seed oil or rapeseed oil, when the addition amount of sunflower seed oil or rapeseed oil is 50 mL/1000 g and 25 mL/1000 g, the content of polycyclic aromatic hydrocarbons (PAHs) in charcoal grilled meat is not obviously affected. Considering the sensory flavor of charcoal grilled meat, it is proper that 50 mL edible oil is used for each 1000 g meat.
