Description

Method that is a kind of while measuring flavor substance in Chinese prickly ash and/or rattan green pepper and its oil product
Technical field
Present invention relates particularly to a kind of methods for measuring flavor substance in Chinese prickly ash and/or rattan green pepper and its oil product simultaneously.
Background technique
Commercially available Chinese prickly ash commodity mainly include Chinese prickly ash (ZanthoxylumbungeanumMaxim.) and rattan green pepper Two kinds of (Zanthoxylumarmatum DC.) is a kind of product of the dual-purpose of drug and food of characteristic.As edible product, " fiber crops, perfume " is Its main flavor characteristic is with spicy fresh perfume for flavouring indispensable in the Sichuan cuisine of characteristic;As medicinal product, embody The chemical component of " fiber crops, fragrant " is also its main active constituent, research find the active constituent in Chinese prickly ash commodity to digestive system, In terms of nervous system, the circulatory system and anti-inflammatory, analgesia, antitumor, anti-oxidant, antibacterial desinsection there is stronger pharmacological activity to make With.Currently, Chinese prickly ash (rattan green pepper) master is used in the form of two kinds of Seasoning Ingredients and processed goods (Zanthoxylum essential oil/Tengjiao oil) as food, flower Green pepper oil (Tengjiao oil) is directly to impregnate Chinese prickly ash (rattan green pepper) or application organic solvent extraction, SCF-CO 2 etc. side with edible oil Chinese prickly ash made from method (rattan green pepper) essential oil mixes the made flavored oils with spicy hot taste with appropriate amount of edible oil.
Fragrance matter in Chinese prickly ash commodity is mainly the volatility such as volatile oil, including alkenes, alcohols, ketone, aldehydes, esters Ingredient, volatile oil is higher with limonene, linalool content in Chinese prickly ash, wherein limonene content highest, and rattan green pepper is with linalool, lemon Alkene content is higher, wherein linalool content highest;Spicy components are mainly using sanshool as the unsaturated fat of the chain of representative Sour amide substance mainly includes hydroxyl-alpha-sanshool, hydroxy-beta-sanshool, hydroxyl-γ-sanshool etc., Chinese prickly ash and rattan green pepper In all with hydroxyl-alpha-Chinese pepper cellulose content highest.Currently, in the quality assessment standard of Chinese prickly ash (rattan green pepper) and Zanthoxylum essential oil (Tengjiao oil) In, mostly using sensory evaluation as main method, and the bound requirements of each standard have difference, this make to Chinese prickly ash (rattan green pepper) and The spicy hot taste of Zanthoxylum essential oil (Tengjiao oil) determines that shortage is scientific, does not have accuracy and objectivity, it is difficult to realize standardization and determine Quantization.Although part research has carried out quantitative analysis to spicy components or fragrance matter, the flavor substance of Chinese prickly ash includes fiber crops Taste substance and fragrance matter.Single measurement fragrance matter content or the content of spicy components are as Chinese prickly ash or Zanthoxylum essential oil Quality assessment standard does not have representativeness, cannot really reflect the inherent product of Chinese prickly ash (rattan green pepper) and Zanthoxylum essential oil (Tengjiao oil) comprehensively Matter.
Spicy components detection method of content mainly has ultraviolet spectrophotometry and high performance liquid chromatography (HPLC) etc. at present, The case where wherein what spectrophotometry measured is the content of total spicy components, cannot reflect each spicy component.HPLC method has easy Operation, the features such as high sensitivity and stability are good, it has also become the main method of analysis measurement spicy components.However in Zanthoxylum essential oil In the measurement of (Tengjiao oil) spicy components, frequently with the spicy components in methanol extraction Zanthoxylum essential oil (Tengjiao oil), to being formed after extraction Immiscible two liquid carry out liquid separation methanol solution taken to be analyzed, method easily causes Zanthoxylum essential oil (Tengjiao oil) spicy components Not exclusively, quantitative analysis is inaccurate for extraction.Currently, fragrance matter assay frequently with gas chromatography measurement limonene and Linalool content, and gas chromatography operation is more complex, danger coefficient is higher, and popularization is more difficult, using high performance liquid chromatography Measurement Chinese prickly ash (rattan green pepper) and Zanthoxylum essential oil (Tengjiao oil) fragrance matter are seldom related to, and do not measure spicy components and flavor more simultaneously The report of matter.Therefore, a kind of easy, accurate numb taste object analyzed in measurement Chinese prickly ash (rattan green pepper) and Zanthoxylum essential oil (Tengjiao oil) is established Matter and fragrance matter are the method for corporate target, and the objective quality standard of science is established to it, to Chinese prickly ash (rattan green pepper) and its The quality of Related product controls and scientific evaluation is of great significance.
