Benefits of technology

This patented process involves treating citrus fruits called Torrefa plants (or sweet cherries) before they grow on trees or other crops. By applying heat and pressurized water at certain temperatures, it breaks down some parts of these plant tissue into smaller molecules like hydroxyproline and carvone glycosides while leaving behind more important compounds such as linalool-3 - an alpha pinane found naturally occurring in many species of this genus. These extracted components have potential benefits beyond their original purpose due to its unique chemical structure. They could potentially help make food smoking easier without adding too much sugar during combustion compared to conventional methods used alone.

Problems solved by technology

Technologies described by Liaoqiu Yankeana (LJPY) include different techniques like sublimination, hydrothermal evaporation, microspray pyro lycopheresis, sonochemistry, laser irradiation, thermal decomposition, molecular imprinted technique, and nano-paraffins. These technics aim at providing new sources of useful compounds while minimizing harmful side effluents during industrial processes.

Embodiment 1

[0023]Weigh a certain amount of fresh Torreya aril, wash it with water, remove surface dust and impurities, and crush it until the particle size is 0.5-2mm. Put 500 g of crushed torreya aril particles into a steam explosion device, add deoxygenated deionized water at a liquid-solid mass ratio of 0.4:1, control the steam pressure at 1 Mpa, and perform steam explosion treatment for 5 minutes. Then transfer the torreya aril treated by steam explosion to a stainless steel extraction tank, transport deoxygenated deionized water to the extraction tank at a flow rate of 15mL / min, extract at a pressure of 5Mpa and a temperature of 110°C for 30min, and then release the pressure , to collect the first part of the extract. Keep the pressure at 5Mpa, increase the temperature to 150°C, extract for 60min, release the pressure, and collect the second part of the extract. The first part of the collected extract was subjected to AB-8 non-polar macroporous adsorption resin chromatography, and ...

Embodiment 2

[0025] Weigh a certain amount of fresh Torreya aril, wash it with water, remove surface dust and impurities, and crush it until the particle size is 0.5-2mm. Put 500 g of broken aril particles of Torreya torreya into the steam explosion device, add deoxygenated deionized water according to the liquid-solid mass ratio of 0.8:1, control the steam pressure to 3Mpa, and carry out steam explosion treatment for 8 minutes. Then the torreya aril treated by steam explosion was transferred to a stainless steel extraction tank, and deoxygenated deionized water was delivered to the extraction tank at a flow rate of 15mL / min. Under the condition of 6Mpa, the temperature was raised to 120°C, and the extraction was carried out for 30min. Release the pressure, collect the first part of the extract; maintain the pressure at 6Mpa, continue to raise the temperature to 170°C, extract for 90min, release the pressure, and collect the second part of the extract. The first part of the collected extra...

Embodiment 3

[0027] Weigh a certain amount of fresh Torreya aril, wash it with water, remove surface dust and impurities, and crush it until the particle size is 0.5-2mm. Put 500g of broken particles of Torreya torreya aril into the steam explosion device, add deoxygenated deionized water at a liquid-solid mass ratio of 0.6:1, control the steam pressure at 2Mpa, and carry out steam explosion treatment for 10 minutes. Then transfer the torreya aril treated by steam explosion to a stainless steel extraction tank, transport deoxygenated deionized water to the extraction tank at a flow rate of 15 mL / min or less, raise the temperature to 130°C under the condition of 7Mpa, and extract 60min, release the pressure, collect the first part of the extract; maintain the pressure at 7Mpa, continue to raise the temperature to 180°C, extract for 120min, release the pressure, and collect the second part of the extract. The first part of the collected extract was chromatographically treated with AB-8 non-p...

Abstract

The invention discloses a method for continuously extracting torreya grandis flavone and essential oil from torreya grandis aril. The torreya grandis aril is taken as a raw material, and torreya grandis flavone and essential oil products are obtained through four steps of cleaning breaking, steam explosion treatment, subcritical water level extraction and separation purification. According to the method, a steam explosion pre-treatment technology and a subcritical water extraction technology are applied to the torreya grandis flavone and essential oil active ingredient research, continuous extraction of torreya grandis flavone and essential oil is realized, not only is the extraction ratio increased, but also the problems of long extraction time, residual solvents, environmental pollution and the like are solved, and the content of alpha-pinene in the essential oil product is quite high.
