Embodiment 1
[0030] Accurately weigh 66g of the pretreated tomato, put it into the extraction tank, add 1600mL of pure water, seal the tank, turn on the agitator, adjust to 120r / min, turn on the heater, heat to 110°C and pressurize, when When the pressure gauge reaches 1 MPa, stop pressurizing, and continue heating and extracting at 110°C for 30 minutes. After the extraction, turn on the circulation pump, cool the steam released from the extraction tank with cooling water, and then further cool down after passing through the low-temperature cooling tank, and finally the extract enters the receiving tank, and the extraction rate is 342.4 μg / g measured by ultraviolet spectrophotometry.
Embodiment 2
[0032]Accurately weigh 66g of the pretreated tomato, put it into the extraction tank, add 1600mL of pure water, seal the tank, turn on the agitator, adjust to 120r / min, turn on the heater, heat to 120°C and pressurize, when When the pressure gauge reaches 1 MPa, stop pressurizing, and continue heating and extracting at 120°C for 30 minutes. After the extraction is finished, turn on the circulation pump, cool the steam released from the extraction tank with cooling water, and then further cool down after passing through the low-temperature cooling tank, and finally the extract enters the receiving tank, and the extraction rate is 848.0 μg / g measured by ultraviolet spectrophotometry.
Embodiment 3
[0034] Accurately weigh 66g of the pretreated tomato, put it into the extraction tank, add 1600mL of pure water, seal the tank, turn on the agitator, adjust to 120r / min, turn on the heater, heat to 130°C and pressurize, when After the pressure gauge reached 1 MPa, the pressurization was stopped, and the extraction was continued at 130°C for 30 minutes. After the extraction, turn on the circulation pump, cool the steam released from the extraction tank with cooling water, and then cool it further after passing through a low-temperature cooling tank. Finally, the extract enters the receiving tank. The extraction rate is 689.6 μg / g measured by ultraviolet spectrophotometry.
