Embodiment 1

[0022] Take 200g of fresh Salmonella fruit, add 50ml of water to infiltrate it, put it into a steam explosion reactor, feed saturated water vapor, after 1.4MPa treatment for 4min, release it rapidly from the reactor and explode it, take 30g of Salmonella fruit after drying Steam-explode the billet, add 200ml of n-hexane, reflux extraction at 80°C for 2 hours in a Soxhlet extractor, filter, evaporate the obtained oil solution with a rotary evaporator at 40-60°C and 0.08-0.09MPa under reduced pressure, and recover the organic solvent. The fruit oil of Salmonella was obtained, and the oil yield was 18.02%. Add 70% ethanol solution to the oil meal at a solid-to-liquid ratio of 1:10, extract in a water bath at 80°C for 2 hours, repeat 3 times, and combine the filtrates to obtain a flavonoid solution with an extraction rate of 2.70%. The residue of oil and flavonoids extracted was placed in a pyrolysis reactor and treated at 500°C for 2 hours to obtain activated carbon with a yield ...

Embodiment 2

[0024] Compared with Example 1, the steam explosion treatment conditions are different.

[0025] Take 200g of fresh Salmonella fruit, add 100ml of water to infiltrate it, put it into a steam explosion reactor, feed saturated water steam, and after 1.5MPa treatment for 5min, release it rapidly from the reactor and blast it. After drying, take 30g of Salmonella fruit steam Explode the raw material, add 200ml of n-hexane, reflux extraction in a Soxhlet extractor at 80°C for 2h, evaporate the obtained oil solution with a rotary evaporator at 40-60°C and 0.08-0.09MPa under reduced pressure, recover the organic solvent, and obtain the salt skin Tree fruit oil, the oil yield is 18.13%. Add 70% ethanol solution to the oil meal at a solid-to-liquid ratio of 1:10, extract in a water bath at 80°C for 2 hours, repeat 3 times, and combine the filtrates to obtain a flavonoid solution with an extraction rate of 2.89%. Put the residue of extracted oil and flavonoids into a pyrolysis reactor ...

Abstract

The invention discloses a technology for the steam explosion treatment of a yellow wood fruit and the comprehensive utilization of grease and flavone thereof, and the like. In the method, the yellow wood fruit is firstly arranged in a steam explosion reactor and is pumped with saturated steam for treatment for 3 to 10 minutes under the pressure condition of 1.4MPa to 2.0MPa; then the mixture is quickly discharged from the reactor for explosion; a blank obtained through the steam explosion is naturally dried or arranged in a drying box for drying; an organic solvent is added for reflux extraction; a rotary evaporator is used for decompressing and evaporation; the solvent is recycled, thus obtaining the oil of the yellow wood fruit. An ethanol liquid is added into the oil meal and then a flavone liquid is obtained through reflux extraction. The remainder after extracting the grease and the flavone are manufactured into active carbon through thermal treatment, thus realizing the comprehensive utilization of the yellow wood fruit.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of plant fruits, and in particular relates to a technology of steam explosion treatment, oil and flavonoid extraction and comprehensive utilization of the fruit of Salmonella chinensis. technical background [0002] Rhus chinensis Mill., a species of Rhus chinensis Mill. in the Anacardaceae family, also known as Galla, is one of the main economic tree species in my country. Saltwood is widely distributed and rich in resources, but it has been left to itself and has not been rationally developed and utilized. According to the survey and statistics, there are about 500,000 mu of wild Salmonella forests in the Dabie Mountains in western Anhui alone, and there are about 5 million wild Salmonella trees. On average, each plant of Salmonella can harvest at least 2kg of fruit per year, and the total output is very considerable. [0003] Salmonella is an oil-rich plant, the oil content of the frui...
