Abstract
The utility model discloses a reagent strips for grape wine sulfur dioxide residual amount detection, including the reagent strips body of many test paper strips and fixed test paper strip, many test paper strips are parallel to each other to tile with the mode that can tear and fix on the reagent strips body, still are fixed with a set of colorimetric card on the reagent strips body, the one end top of test paper strip has the couple, and the lower part is provided with the color development layer that can take place colour variable in sulfur dioxide gas environment in the other end. The utility model has the advantages of simple structure, detect quick, aspect and carry to the concentration range of the sulfur dioxide volume of remaining in the corresponding grape wine of can judging according to the colorimetric card.
Description
Technical field
The utility model relates to a kind of detection reagent bar, is a kind of reagent strip for the detection of grape wine sulfur dioxide residual quantity specifically.
Background technology
The brewing process of grape wine all needs add sulfurous gas, mainly contain the effect of two aspects: 1, sterilization provide protection, because sulfurous gas has the effect killing Pericarpium Vitis viniferae surface miscellaneous bacteria; 2, antioxygenation, because sulfurous gas itself is a kind of antioxidant, can protect the characteristics of fruit of wine liquid, moreover it is possible to prevent the oxidation of activeconstituents in wine liquid in wine brewing process. But sulfurous gas addition is not The more the better, human body can be produced the disadvantageous effects such as allergy, acute poisoning by the sulfurous gas of too high amount. Thus, sulfur dioxide residual quantity in grape wine there is strict restriction by national standard. But national standard method comprises multiple steps such as distillation, colorimetric titration, operates loaded down with trivial details.
Practical novel content
The utility model is to solve in existing grape wine sulfur dioxide residual quantity crosses problem that is long and that not easily carry detection time, it is provided that a kind of reagent strip for the detection of grape wine sulfur dioxide residual quantity.
In order to address this problem, scheme of the present utility model is: a kind of reagent strip for the detection of grape wine sulfur dioxide residual quantity, comprise the reagent strip body of many test strip and fixing test strip, many test strip are fixed on reagent strip body with the tiling that is parallel to each other of tearable mode, reagent strip body is also fixed with one group of colorimetric card, the top, one end of described test strip with hook, the color layer that in the other end, bottom is provided with in sulfur dioxide gas environment color can be occurred to change.
Described reagent strip body is rectangle, and test strip is elongated rectangle strip.
Described one group of colorimetric card and many test strip are respectively at up and down two position of reagent strip body with face.
The color layer of described one group of colorimetric card and many test strip is respectively at up and down two position of reagent strip body with face.
Hook in described test strip is PVC material.
The beneficial effects of the utility model are: the advantages such as structure is simple, detection is quick, aspect is carried, and can judge the concentration range of sulfur dioxide residual quantity in corresponding grape wine according to colorimetric card.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reagent strip for the detection of grape wine sulfur dioxide residual quantity of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, reagent strip for the detection of grape wine sulfur dioxide residual quantity of the present utility model, comprise the reagent strip body 1 of many test strip 2 and fixing test strip, many test strip 2 are fixed on reagent strip body 1 with the tiling that is parallel to each other of tearable mode, reagent strip body 1 is also fixed with one group of colorimetric card 4, the top, one end of described test strip 2 with hook 5, the color layer 6 that in the other end, bottom is provided with in sulfur dioxide gas environment color can be occurred to change.
Described reagent strip body 1 is rectangle, and test strip 2 is elongated rectangle strip.
Described one group of colorimetric card 4 and many test strip 2 are respectively at up and down two position of reagent strip body 1 with face.
Preferably, the color layer 6 of described one group of colorimetric card 4 and many test strip 2 is respectively at up and down two position of reagent strip body 1 with face.
Hook 5 in described test strip 2 is PVC material.
Test strip 2 can be fixed on reagent strip body 1 by Double-face gummed paper band, the mode such as water.
The color layer of test strip of the present utility model is the color layer containing gaseous sulfur dioxide fluorescent probe, grape wine will add a certain amount of strong acid, sulfurous gas is released, react with the fluorescent probe in color layer, thus color layer generation color is changed, now, the color show color layer and colorimetric card contrast, can know the roughly scope of sulfur dioxide residual quantity in sample grape wine. Colorimetric card of the present utility model is provided with 5 colour codes, and colour code 1, in deep yellow, represents that in grape wine, amount of sulfur dioxide is greater than 200mg/L; Colour code 2, in yellow, represents that in grape wine, amount of sulfur dioxide is greater than 150mg/L; Colour code 3, in light yellow, represents that in grape wine, amount of sulfur dioxide is greater than 100mg/L; Colour code 4, in faint yellow, represents that in grape wine, amount of sulfur dioxide is greater than 50mg/L; Colour code 5, in white, represents that in grape wine, amount of sulfur dioxide is less than 25mg/L.
During use, test strip 2 being torn, be suspended in test bottle by hook 5, color layer generation color changes, and can obtain test result with colorimetric card contrast.
Above-described embodiment is only for illustration of technological thought of the present utility model and feature, its object is to enable those skilled in the art to understand content of the present utility model and implement according to this, only can not limit patent scope of the present utility model with the present embodiment, namely the equal change that the spirit that all the utility model disclose is done or modification, still drop within the scope of patent of the present utility model.
