Description
Technical field
This utility model belongs to food test technical field, is specifically related to a kind of food colour chemical analysis device.
Background technology
The color of food is a key factor of food sensible quality, and people, when making food, are frequently used food colour as food additive, but, food colour adds excess and can threaten the healthy of people.Therefore, it is necessary to the pigment content in food is detected and controls.
In prior art, the extraction of food colour, it usually needs through solvent extraction and filtration step, and the chemical analysis device of most of food colour, it is that extraction equipment is separated with defecator so that complex operation step, easily causes the loss of pigment extract.
Utility model content
The purpose of this utility model is to provide a kind of food colour chemical analysis device, can solve existing pigment chemistry verifying attachment and be separated with defecator by extraction equipment, the complex operation step caused, the problem that pigment extract easily loses.
The technical scheme of this utility model a kind of food colour chemical analysis device is, including extraction element and colorimetric device, described extraction element includes sample cell and flask with a scale, described sample cell is positioned at the inside of flask, and between the upper end of sample cell and the bottleneck of flask, being sealed by seal member, the mouth of pipe of described sample cell is sealed by the first plug, and lower end is loose structure；Described colorimetric device includes colorimetric comb and sample liquid pipe.
Preferably, described seal member is rubber ring；
Preferably, described sample cell is built-in with filter course, and described filter course is close to the loose structure of sample cell, and is completely covered by described loose structure；
Preferably, described filter course is filter cloth；
Preferably, the outside of described flask is provided with transfer tube, the bottleneck being located proximate to flask of described transfer tube, and one end of transfer tube is connected with described flask, and the other end is sealed by the second plug.
This utility model food colour chemical analysis device provides the benefit that, is combined with defecator by extraction equipment, and operating procedure is simple, does not easily cause the loss of pigment extraction liquid, and can be with the pigment content in fast qualitative or estimation food.

Detailed description of the invention
Below in conjunction with the accompanying drawings, a detailed description of the invention of the present utility model is described in detail, it is to be understood that protection domain of the present utility model is not limited by detailed description of the invention.
As Figure 1-3, a kind of food colour chemical analysis device that this utility model provides, including extraction element and colorimetric device, described extraction element includes sample cell 2 and flask 1 with a scale, and described sample cell 2 is positioned at the inside of flask 1, between upper end and the bottleneck of described flask 1 of described sample cell 2, sealed by dismountable seal member 3, and sample cell 2 can move up and down in flask 1, the mouth of pipe of described sample cell 2 is sealed by the first plug 4, and lower end is loose structure；Described colorimetric device includes colorimetric comb 8 and sample liquid pipe 9, described colorimetric comb 8, is pre-loaded with the standard pigment solution to be measured of concentration known, and the concentration of the pigment solution in each pipe of colorimetric comb 8 is different, and described sample liquid pipe 9 is used for filling pigment extract.
Preferably, described seal member 3 is rubber ring.This utility model food colour chemical analysis device, the food samples 10 of constant weight is positioned in sample cell 2, then in sample cell 2, add the extraction agent of extraction pigment, such as acetone, ethanol etc., meanwhile, extraction agent flow in flask 1 from the bottom of sample cell 2, thus has extraction agent in realizing sample cell 2 and flask 1, but food samples 10 exists only in sample cell 2.After process to be extracted terminates, owing to sample cell 2 can move up and down in flask 1, sample cell 2 is pulled out in flask 1, solution in sample cell 2 outwards leaches, after the solution in sample cell 2 has been filtered, solution is settled to the scale of flask 1, obtain pigment extract, then partial pigment extracting solution is taken in sample liquid pipe 9, the color contrast of pigment solution to be measured with the standard in colorimetric comb 8, get final product qualitative or estimate the pigment content in pigment extract, further, it is possible to achieve the pigment content in fast qualitative or estimation food samples 10.It addition, upper end first plug 4 of sample cell 2 seals, the volatilization of pigment extract can be avoided, when if desired adding extraction heat pigment, it is also possible to the mouth of pipe at sample cell 2 connects condensing tube.
Preferably, preparing the loose structure of the lower end of sample cell 2 for convenience, it makes material and can select corrosion-resistant, high temperature resistant and be difficult to the pottery reacted with other materials.
Preferably, described sample cell 2 is built-in with filter course 5, and described filter course 5 is close to the loose structure of sample cell 2, and is completely covered by described loose structure.Owing to the aperture of filter course 5 is the least, can filter out the impurity of small volume in sample, improve the transparency of pigment extract, on the other hand, filter course 5 is also applied for filtering the sample of small volume.
Preferably, described filter course 5 selects the filter cloth of 600-800 mesh.
Preferably, the outside of described flask 1 is provided with transfer tube 6, the bottleneck being located proximate to flask 1 of described transfer tube 6, and one end of described transfer tube 6 and connects with described flask 1, and the other end is sealed by the second plug 7.Remove the second plug 7, hose connection by transfer tube 6 and vacuum filtration machine, by the assosting effect of vacuum filtration machine, the rate of filtration can be improved；When need not the assosting effect of vacuum filtration machine, with the second plug 7, transfer tube 6 is sealed, thus avoid pigment extract to volatilize from converting interface, and then avoid environmental pollution.
This utility model food colour chemical analysis device, combines extraction equipment with defecator, and operating procedure is simple, does not easily cause the loss of extract, and can be with the pigment content in fast qualitative or estimation food.
An only specific embodiment of the present utility model disclosed above, but, this utility model is not limited to this, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
