Embodiment 1

[0021] After mixing 10g (4.0g litsea cubeba oil, 3.0g turmeric oil, 3.0g eucalyptus oil) plant essential oil compound with 20.0g ethanol and 20.0g Tween80, ultrasonic for 30 minutes, added distilled water to 100mL, mixed, and then heated at 60Mpa Homogenize in a homogenizer for 60 minutes to obtain an antiseptic and fresh-keeping composition emulsion. After the emulsion is diluted 10 times, it is sprayed to process cold fresh pork or green peppers, sealed with PE plastic wrap, and placed in a climate box at 15°C and a humidity of 80%. storage.

Embodiment 2

[0023] After mixing 15g (8.0g litsea cubeba oil, 3.0g turmeric oil, 4.0g eucalyptus oil) plant essential oil compound with 23.0g ethanol and 23.0g Tween80, ultrasonic for 40 minutes, added distilled water to 100mL, mixed, and then heated at 70Mpa Homogenize in a homogenizer for 90 minutes to obtain an antiseptic and fresh-keeping composition emulsion. After the emulsion is diluted 10 times, it is sprayed to process cold fresh pork or green peppers, sealed with PE plastic wrap, and placed in a climate box with a humidity of 80% at 15°C. storage.

Embodiment 3

[0025] 18.0g (6.0g litsea cubeba oil, 8.0g turmeric oil, 6.0g eucalyptus oil) plant essential oil complex mixed with 31.0g ethanol, 31.0g Tween80, ultrasonic 30 minutes, add distilled water to 100mL, mix, then in Homogenize in a homogenizer at 80Mpa for 70 minutes to obtain an antiseptic and fresh-keeping composition emulsion. After the emulsion is diluted 10 times, it is sprayed to process cold fresh pork or green peppers, sealed with PE plastic wrap, and placed in a climate box at 15°C and a humidity of 80%. in storage.

Description

technical field [0001] The invention relates to a plant essential oil antiseptic and fresh-keeping composition based on litsea cubeba oil. Background technique [0002] Fresh food is prone to rot and deterioration due to mechanical damage, microbial contamination, and physiological aging. The gap between my country's anti-corrosion and fresh-keeping technology and developed countries is large. The post-harvest loss of vegetables in my country is as high as 40-50%, and fruits are also up to 30%, causing huge losses. Economic loss, while the average rot rate of fruits and vegetables in developed countries is less than 7%. Therefore, the preservation and preservation of fresh food is one of the important issues faced by my country's food industry and agricultural and sideline products processing industry. At present, the anti-corrosion and fresh-keeping technologies of fresh food at home and abroad mainly include: physical technology preservation, chemical anti-corrosion preser...
