Description
Technical field
The invention belongs to technical field of food detection, in particular it relates to a kind of specified plant oil safe screen look into detection method,
Equipment and system.
Background technology
Vegetable oil is that resident uses most common flavouring, while being again the medium for heating raw material, has seasoning and heat transfer concurrently
Effect.Vegetable oil as needed by human body one of important nutrient, be our daily life indispensable requisites.But
It is that vegetable oil quality problems constantly threaten the health of people in recent years, even waste oil is returned the report of dining table and seen repeatly not
It is fresh：There are some bad retailers that reusable vegetable oil returned into dining table again by simple process, and the plant of Reusability
Thing oil constitutes significant threat for health.
Differentiate method primary chemical detection method, large-scale instrument method, fluorescence method, the Rapid Screening method of poor oil at present.Chemistry
The method of detection is usually to need to be extracted with organic reagent, separate etc. just be tested after pre-treatment step, preceding place
Reason process operation is complicated and can use to poisonous organic reagent；The existing method by detecting acid value and peroxide value is only
Can simply judge whether vegetable oil is expired, and the safe examination of vegetable oil cannot be identified, coverage rate is narrow.And report on the market
Some precision instruments for example then need to purchase very expensive large-scale instrument using methods such as nuclear magnetic resonance, mass spectrums, and to instrument
Storage environment and very harsh to the requirement of the professional technique of operating personnel, it is impossible to realize live real-time detection；Wherein, use
Detection technique of fluorescence needs also exist for using chemical extraction pre-treatment come the method for differentiating poor oil, and instrument used is also relatively more high
The sepectrophotofluorometer of expensive such as Shimadzu Corporation, and some use the method for three-dimensional fluorescence to also need at substantial amounts of follow-up data
Reason.The method that the method for quick discriminating poor oil detects polar compound such as the electrical conductivity of German moral figure on the market at present, is current
With immediate technical scheme of the invention, but it can only judge the quality of frying oil, and detection temperature needs control in 40-
Between 200 DEG C, also periodically instrument is corrected in addition, program is cumbersome.And, with the fast sieve side of electrical conductivity principle
Method can only detect one index of polar compound, so be only capable of detecting the poor oil that polar compound is exceeded, adulterated for olive oil,
Sesame oil is adulterated, cross poor oil of shelf-life etc., and this kind of quick screening cannot be detected.
At present, to using physico-chemical method, gas chromatography and liquid chromatography the discriminating of olive oil more.These three methods are all
Needs carry out chemical pre-treatment, and complex operation, detection single cost is very high.And nuclear magnetic resonance technique is because expensive, it is difficult to general
And, it is limited to research work more.
Additionally, in the vegetable fat field of circulation, sesame oil adulteration happens occasionally and has increasingly serious gesture, urgently
Need to set up scientific, rapid and accurate, effective detection method, carry out the adulterated detection of sesame oil.China's grain and oil health detection mark
There is no the announcement of sesame oil quantitative approach in standard.Method now conventional to sesame oil detection has Weiler mikey method and Bo Duoyin
Method, both approaches measuring principle is identical, i.e., using sesamol and the developer reaction in sesame oil, produce red product to go forward side by side
Row is determined.Both approaches are required for carrying out chemical pre-treatment, complex operation.
It is therefore desirable to develop a kind of relatively simple easy-to-use method and its equipment, system be used to detect include olive oil and
Quality of the sesame oil in interior specified plant oil.It is desirable that quickly, simply, easily specified plant oil is existing desirable to provide one kind
Field real-time detection method, it can be used for supervision law enforcement, restaurant and oil enterprise and checks oneself, or even the regular self-inspection of family's oil product.
The content of the invention
Detection method is looked into it is an object of the present invention to provide a kind of specified plant oil safe screen, the method includes：It is determined that
The health factor y of the specified plant oil；And according to the health factor y of the identified specified plant oil, it is determined that described
The quality of specified plant oil.
It is a further object to provide specified plant oil safe screen inspection measurement equipment, the equipment includes：Exciting light
Source, the light for going out specific wavelength to the specified plant fry dried food ingredients；Fluorescence signal acceptance division, for receiving the specified plant oil
The fluorescence signal sent under the exciting of the light of the specific wavelength；And signal processing part, for the fluorescence to the reception
Signal is processed, to obtain the data signal of the intensity for characterizing the fluorescence signal..
A further object of the present invention is to provide a kind of detecting system of the safe examination of specified plant oil, and the system includes：
Foregoing equipment, as detection induction end；And the data communicated with the detection induction end by communication
Control terminal；Wherein, the data control terminal is received from the detection induction end by communication and characterizes specific plant
Thing oil specific wavelength excite light irradiation under produce fluorescence signal intensity data signal, and according to foregoing method come

Specific embodiment
To make those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
The invention will be further described for formula.It may be noted that in the present invention, specified plant oil refers to olive oil or sesame oil.
In the present invention, the principle of fluorescence can be produced under the exciting of the exciting light of specific wavelength according to specified plant oil,
Specified plant oil is excited with the light of specific wavelength, and gathers specified plant oil and sent in the case where the light of above-mentioned specific wavelength is excited
Fluorescence signal.Afterwards, the data signal for characterizing above-mentioned fluorescence signal intensity is obtained.For example, being changed fluorescence by a series of
(i.e. its longitudinal axis value is big for the peak area of aforementioned fluorescent signal in spectrum curve (its transverse axis is wavelength, and the longitudinal axis is fluorescence signal intensity)
In the area that the part of baseline is covered) corresponding data signal is converted to, the data signal is and characterizes the fluorescence signal
