Abstract

The disclosure relates to the technical field of food processing, particularly to a grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat. The grilling method comprises: Step 1, dispensing to-be-grilled meat into boxes with sealing covers, and adding edible oil into the boxes, wherein a ratio of edible oil to the weight of meat is 25˜50 mL/1000 g, and sealing the covers; Step 2, carrying out plasma treatment on the meat sealed in Step 1; and Step 3: placing the meat treated using plasma onto a grill and grilling. The grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat is simple, convenient, and easy to operate; it is not needed adding unessential food additives, thereby significantly reducing the content of polycyclic aromatic hydrocarbons in meat products, saving cost and improving safety while remaining the flavor of food itself.

First claim

What is claimed is:

1. A grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat, comprising the following steps:
step 1, dispensing to-be-grilled meat into boxes with sealing covers, and adding edible oil into the boxes, wherein a ratio of edible oil to the weight of meat is 25˜ 50 mL/1000 g, and sealing the covers;
step 2, carrying out plasma treatment on the meat sealed in step 1; and
step 3: placing the meat treated using plasma onto a grill and grilling, wherein the edible oil is sunflower seed oil;
wherein before dispensing, the meat is cut into strips with a thickness of 1˜2.5 cm, and then soaked into soaking solution which is prepared by water, an acidic flavoring agent and edible baking soda;
wherein the acidic flavoring agent is vinegar, the pH of the soaking solution is 3.3˜3.8,
wherein a ratio of to-be-grilled meat to soaking solution is 1000 g/1000 mL, and the condition of soaking is soaking for 1˜4 h at 4° C.; and
wherein in step 2, the specific plasma treatment method is that the sealed meat is placed in a electric field plasma non-thermal sterilization equipment, treatment parameters are set as an electrode gap being 4.0 cm, the voltage of the electric field being 80 kV, and discharging time being 120˜180 s.

2. The grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat according to claim 1 , wherein the specific grilling method in step 3 is as follows: a solid alcohol block is used to ignite a charcoal fire; after the open fire of all the charcoal is ended, the sample meat is placed on the grill which is far away from a fire source by 5 cm; the meat is turned over every 2 min; when the grilling time is 12 min, the internal temperature of the sample is measured with a probe thermometer; when the internal temperature reaches 75° C., the grilling is stopped; when the internal temperature does not reach 75° C., the grilling is continued, until the internal temperature is 75° C.

3. The grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat according to claim 2 , wherein when the internal temperature of the sample reaches 75° C., the surface temperature of the charcoal fire at the moment is measured with an infrared thermometer, and the surface temperature of the charcoal fire is kept to be 180˜220° C.

4. The grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat according to claim 1 , wherein the kinds of meat comprise chicken, duck, beef, pork and mutton.
