Embodiment 1

[0045] Embodiment 1: Adopt the device that adopts nitric oxide gas fumigation to improve pork quality;

[0046] 1), open the airtight door on the fumigation container 1, place the pork slices 4 flatly above the plastic mesh plate 2 in the fumigation container 1, and then close the airtight door;

[0047] 2), Nitrogen flushing: Open the nitrogen cylinder, the nitrogen concentration in the cylinder is 99.9%, turn the nitrogen pressure reducing valve, adjust the nitrogen flow rate through the rotameter, pass the nitrogen into the aluminum foil 9 and the syringe 7 through the nitrogen pipe; adjust the one-way The valve 8, the three-way valve 6, and the air intake valve 5 make the aluminum foil bag 9 and the syringe 7 communicate with the fumigation container 1, and open the exhaust valve 3 on the fumigation container 1; the nitrogen in the aluminum foil bag 9 passes through the first pipe 10-1 , three-way valve 6, second pipe 10-2, air intake valve 5 flow into the fumigation conta...

Embodiment 2

[0053] Embodiment 2: the control treatment of fresh pork fumigated without nitric oxide gas;

[0054] Step 1), pork pre-treatment: Remove the visible fascia and fat from the longissimus muscle of the back of the fresh pig within 6 hours after slaughter, and trim it to 5×5×2cm 3 (weight 60g) meat slices (pork slices), the meat slices are placed flatly above the plastic net inside the fumigation container.

[0055] Nitrogen flushing: open the nitrogen cylinder, turn the nitrogen pressure reducing valve, adjust the nitrogen flow rate through the rotameter, pass the nitrogen into the aluminum foil 9 and the syringe 7 through the nitrogen pipe; adjust the one-way valve 8, the three-way valve 6, and the intake valve 5. Make the aluminum foil bag 9 and the syringe 7 communicate with the fumigation container 1, and open the exhaust valve 3 on the fumigation container 1; the nitrogen in the aluminum foil bag 9 passes through the first pipe 10-1, the three-way valve 6, and the second pi...

Embodiment 3

[0058] Example 3: Fumigate fresh pork with nitric oxide gas at a concentration of 40 μL / L;

[0059] Step 1), pork pre-treatment: Remove the visible fascia and fat from the longissimus muscle of the back of the fresh pig within 6 hours after slaughter, and trim it to 5×5×2cm 3 (weight 60g) meat slices (pork slices), the meat slices are placed flatly above the plastic net inside the fumigation container.

[0060] Step 2), nitrogen flushing device: open the nitrogen cylinder, turn the nitrogen pressure reducing valve, adjust the nitrogen flow rate through the rotameter, and pass the nitrogen into the aluminum foil 9 and the syringe 7 through the nitrogen pipe; adjust the one-way valve 8 and the three-way valve 6. The air intake valve 5 makes the aluminum foil bag 9 and the syringe 7 communicate with the fumigation container 1, and the exhaust valve 3 on the fumigation container 1 is opened; the nitrogen in the aluminum foil bag 9 passes through the first pipe 10-1, the three-way ...

Abstract

The invention relates to a device for improving pork quality by adopting nitric oxide gas fumigation and a method using the device. The device comprises a fumigation container, an aluminum foil bag and a three-way valve, the three-way valve is sequentially connected to a first pipe, a second pipe and an injection pipe; one end of the first pipe is communicated with the three-way valve, and the other end of the first pipe is communicated with the aluminum foil bag; a one-way valve is mounted on the first pipe; one end of the second pipe is communicated with the three-way valve, and the other end of the second pipe is communicated with the top of the fumigation container; a gas inlet valve is mounted on the second pipe; the aluminum foil bag is communicated with the fumigation container through the first pipe, the one-way valve, the three-way valve, the second pipe and the gas inlet valve; and one end of the injection tube is communicated with the three-way valve, and the other end is connected to an injector. The device and method are simple to operate, low in cost, free of harmful chemical residues and wide in application prospect.

Description

technical field [0001] The invention relates to a device and a method for improving the quality of pork by nitric oxide gas fumigation, and belongs to the technical field of pork processing. Background technique [0002] Pork occupies an important position in people's dietary life, and it is also the most consumed meat food by Chinese residents. At present, with the improvement of people's living standards, high-quality fresh meat has gradually become the primary goal pursued by meat producers and consumers. However, the current low level and instability of pork quality affect the development of production enterprises and the satisfaction of consumers. Drip loss is an important indicator of pork quality. According to reports, the drip loss of pork in my country is as high as 5%, which is 1.5% higher than the average in developed countries. Juice, mouthfeel and other quality indicators have a negative impact. Therefore, seeking effective measures to minimize the drip loss o...
