Abstract
The utility model relates to an oxidation detector for unsaturated fatty acid in emulsion. The utility model is used for detecting the oxygen consumption of substances which are easy to oxidize in an emulsion system under a simulated packing state, particularly for the oxidation detection of a substance which is easy to oxidize and is unsaturated fatty acid in the food system, the cosmetic system and the emulsion system during a shelf life. The utility model belongs to the technical field of detection of substances which are easy to oxidize in industries, such as food and cosmetics. When simulating a packing state, the device comprises three conditions of air, vacuum pumping and vacuum pumping nitrogen filling. An oxidation kinetics model or a correlation curve is established in a way that when carrying out oxygen consumption detection, the device is matched with advanced detecting measures, such as high-pressure liquid phase, gas chromatograph, etc. By adopting the oxygen consumption detection of the device, conclusions of products which are produced in volume production in a factory can be directly concluded through the model or the correlation curve, omitting the using costs of a noble instrument and advanced detecting measures, such as high-pressure liquid phase, gas chromatograph, etc. which have high prices.

Background technology:
Before the utility model was made, in prior art, the unsaturated fatty acid that has only pure oil body to be adopted the detection of advanced meanses such as high-pressure liquid phase, gas chromatography.Detection in the emulsion system of most of actual conditions is still needed in conjunction with advanced meanses such as high-pressure liquid phase, gas chromatographies.Experiment by this device, cooperate advanced detection meanss such as high-pressure liquid phase, gas chromatography, after setting up oxidation kinetics model or related experiment curve, adopt the oxygen consumption of this device to detect, can directly infer conclusion, save use costs valuable and advanced detection meanss such as the high-pressure liquid phase consumptive material costliness, gas chromatography by model or empirical curve.
Summary of the invention:
The utility model is imitation during packed state, comprises air, vacuumizes, under three kinds of situations of vacuum nitrogen filling, easy the to be indirect oxygen consumption oxidation pick-up unit of the readily oxidizable substance in food, the cosmetics emulsion system---unsaturated fat acid oxidase.
Main solution of the present utility model is achieved in that
In the utility model device, quantitative emulsion fluid to be measured is housed below the reacting tank body 11, by regulating each valve, the top of reacting tank body 11 can be realized containing air, vacuumized, three kinds of situations of vacuum nitrogen filling, and one group of a plurality of oxygen electrode is installed on the electrode tip holder 16 hermetically; Experiment by this device, every the corresponding time, pass by annular pressing plate 19 with injection needle and to be pressed in sheet rubber 18 on the annular flange 17, the height of each electrode tip holder 16 of one group is extracted emulsion fluid out in the reacting tank body 11, and reads the reading of the oxygen electrode on the corresponding electrode seat 16; In conjunction with advanced detection meanss such as high-pressure liquid phase, gas chromatographies, the oxidation of extracting emulsion fluid out is tested, set up oxidation kinetics model or related experiment curve; To the product of same batch process, factory can adopt this device, according to above-mentioned oxidation kinetics model or correlation curve, finishes inspection process, need not high-pressure liquid phase, advanced detection means such as gas chromatography.
Compared with the prior art the utility model has the following advantages:
Imitation is during packed state, comprises air, vacuumizes, under three kinds of situations of vacuum nitrogen filling, when the oxygen consumption by this device detects, cooperates advanced detection meanss such as high-pressure liquid phase, gas chromatography, sets up the oxidation kinetics model; Adopt the oxygen consumption of this device to detect again, can directly infer conclusion, saved the use cost of the advanced detection meanss such as high-pressure liquid phase, gas chromatography of expensive instrument and high price consumptive material by model.Easy the to be indirect oxygen consumption oxidation pick-up unit of the readily oxidizable substance in food, the cosmetics emulsion system---unsaturated fat acid oxidase.
