Embodiment

[0078] Oak Flavor Extraction

[0079] Use 150ml tap water or 12% ethanol / water or 100% ethanol to extract 40g oak. The sample was stirred (control sample) or sonicated for 10 seconds and 30 seconds, and then the liquid sample was sieved (about 0.8mm mesh), and then filtered with No. 1 Whitman filter paper. The filtrate sub-sample was diluted 3.5 times with water and sent to the Australian Wine Research Institute for oak flavor analysis by GC-MS.

[0080] Result

[0081] The quantitative limit of chemical substances identified by GC-MS (the amount expressed in μg / L in the diluted extract) is guaiacol 3.5, eugenol 35, oak lactone 35, vanillin 35 and furfural 35. Other chemical substances analyzed but below the quantitative limit are: 4-methylguaiacol, 4-ethylphenol, 4-ethylguaiacol and 5-methylguaiacol.

[0082] The extraction data shows that in the same extraction time, compared with the control sample, the use of the above method for ultrasonic treatment can promote the extraction o...

Abstract

The present invention describes a method and apparatus for aqueous extraction of chemical compounds from solid material in which the solid material is entrained in an extraction liquid phase that flowed around immersed sonotrodes emitting radial or focused high energy ultrasonic waves. A significant increase in extracted material and decreases in extraction time is observed.

Description

technical field [0001] The present invention relates to improving the liquid phase extraction of important chemical constituents in materials by using a preferably submerged sonotrode. Background technique [0002] Wooden barrels have long had an important place as common containers for liquids and food. However, with the development of material handling methods and other structural materials that are more practical in today's conditions, wooden barrels have been almost completely replaced except for the aging of wines and spirits. [0003] Wines and spirits stored in oak barrels have ideally alluring organoleptic properties, composition and organoleptic qualities. Therefore, oak barrels are used in the production of many crafted catering red wines and white wines. Most of the wooden barrels used for wine aging all over the world have a volume of 190 to 500 liters. For table wine, a volume of about 225 liters is most common. [0004] Oak contains cellulose, hemicellulose...
