Description
Technical field
The utility model relates to the aroma component extraction equipments such as a kind of fruit, vegetables.
Background technology
Aroma component as affecting, eat raw, the key factor of processing quality by fruit, and its component, kind and content are one of important composition factors of taste of fruit quality, is also the important indicator that fruit quality is evaluated.
The aroma component of fruit often adopts after extraction binding analysis instrument again to analyze and detect.Solid-phase Microextraction (Solid Phase Micro-extraction, SPME) as a kind of novel non-solvent fruit aroma, analyze pre-treating method, its selective extraction characteristic has overcome the shortcomings such as the pre-treatment sample demands such as traditional vapor distillation method, solvent extraction, supercritical fluid extraction are large, length consuming time; Be convenient to realize robotization and be easy to and the efficient separated detection means coupling such as chromatogram, electrophoresis, liquid phase, gas chromatography-mass spectrum (GC-MS), and being applicable to the pretreatment technology that gas, liquid and solid sample are analyzed.At present, fruit, vegetables aroma component are measured normal employing solid-phase microextraction technology, and this technology has been widely used in food and the analysis of garden crop aroma component.But adopt the supporting extraction flask of gas chromatography mass spectrometry instrument to find, because sample size few (about 8g) in its bottle, head space space are little, its analysis result can not accurately reflect that the drupe classes such as fruit aroma component, the particularly pomaceous fruit such as pears, apple, peach, apricot, orange class, potato class, the fruits and vegetables quantitative test time error that melon equal-volume is larger are very large.
Summary of the invention
For fruit, vegetables aroma components such as accurate, complete extractions, the utility model provides a kind of analysis result accurate, simple in structure, easy to operate fruits and vegetables aroma component extraction equipment and method of making of knowing clearly, and its technical scheme of taking is:
This device comprises iron stand, test tube clamp, sample introduction handle, solid phase micro-extracting head, tool plug wide-necked bottle and constant-temperature heating magnetic stirring apparatus, the right-hand member of test tube clamp is fixed on the top of iron stand, the left end of test tube clamp and sample introduction handle fix, lower end and the solid phase micro-extracting head of sample introduction handle fix, and solid phase micro-extracting head can move up and down, tool plug wide-necked bottle is arranged on constant-temperature heating magnetic stirring apparatus, solid phase micro-extracting head can insert the tool plug wide-necked bottle that is positioned at its below, constant-temperature heating magnetic stirring apparatus is provided with rotating speed display screen, rotor speed setting knob, temperature display and Temperature Setting knob.Tool plug wide-necked bottle can be replaced by triangular flask.
This extraction equipment can be selected sample stripping and slicing or making beating according to detecting sample, heating-up temperature and balance are set, adsorption time, with respect to the supporting extraction flask of gas chromatograph-mass spectrometer (8g), greatly increased sample scope (10g-100g), overcome the large defect of testing result difference that big-and-middle-sized fruits and vegetables cause because sampling amount is little, by regulating the rotating speed of extraction temperature and rotor to guarantee the even of fragrance, stable distributing, strengthened the adsorpting aggregation of extracting head to each component in head space in bottle, when machine is detected, aroma component kind and content are resolved more abundant, analysis result more tends towards stability, accurately, more can express the aroma component of fruits and vegetables completely.
This extraction equipment has the features such as reasonable in design, simple in structure, workable, has the advantages such as extraction cost is low, analytical effect is good when fruits and vegetables fragrance is analyzed.
