Problems solved by technology

[0006] First of all, it is edible oil that dissolves Sudan Red, and the cost is relatively high;
[0007] Secondly, the alcohol directly volatilizes into the air and cannot be used repeatedly, which further increases the detection cost;
[0008] Third, there is no professional testing tool provided

specific Embodiment 1

[0033] The Sudan red detection device in the chili food of the present embodiment, the structural diagram is as follows figure 1 shown. The device includes symmetrically distributed evaporating containers 1 and condensing containers 2, the evaporating container 1 and the condensing container 2 are connected at the top by a pipe 3, and the pipe 3 is provided with a valve 5; the top of the evaporating container 1 is provided with a rubber Plug 4, the evaporation container 1 is composed of upper and lower parts made of transparent material with sealed threaded connection, and the condensation container 2 is composed of upper and lower parts made of transparent material with sealed threaded connection.

[0034] In the above-mentioned Sudan red detection device in chili food, a heating device 6 is provided at the bottom of the evaporation container 1, and a cushion block 7 is provided at the bottom of the condensation container 2.

[0035] The Sudan red detection device in the abo...

specific Embodiment 2

[0047] The object detected in this embodiment is the sample that turns red after the green peppers purchased in the market are placed for a period of time. Because what buy is green capsicum, therefore can determine that can not contain Sudan red in this capsicum, verifies the method of the present invention with this.

[0048] The detection method comprises the following steps:

[0049] Step a, washing the chili food to be tested

[0050] The chili food is put into water and washed repeatedly until the washing liquid is colorless;

[0051] Step b, soaking the chili food to be tested

[0052] Close the valve 5 on the pipeline 3, put the chopped chili food to be tested in the evaporation container 1, inject acetone from the rubber stopper 4, until the chili food to be tested is submerged, soak for 24h, and then put the chili food to be tested from Take out in evaporation container 1; step c, evaporate acetone solution

[0053] Open the valve 5 on the pipeline 3, heat the ev...

Abstract

The invention relates to a device and a method for detecting Sudan red in chili food, belonging to the field of food detection. The device comprises an evaporation container and a condensation container which are symmetrically distributed; the top of the evaporation container is connected to the top of the condensation container through a pipeline; a rubber plug is arranged at the top of the evaporation container; the evaporation container and the condensation container respectively consist of an upper part and a lower part which are connected by a sealing thread and are made of transparent materials. The method comprises the following steps: firstly, washing chili food to be detected, then soaking the chili food to be detected, evaporating an acetone solution, and finally, judging whether the chili food contains the Sudan red. The device and the method for detecting the Sudan red in the chili food can be used for detecting whether the chili product contains the Sudan red by adopting physical means, and are simple and easy to operate and convenient to popularize; furthermore, by adopting the device and the method, volatile liquid cannot volatilize into the air, thus the harm of the volatile liquid to the human body is avoided; the device and the method are safe and environment-friendly, and the liquid can be repeatedly used, so that the detection cost is reduced.

Description

technical field [0001] A detection device and method for Sudan red in chili food belongs to the field of food detection, in particular to a detection device and method for Sudan red in chili products. Background technique [0002] Sudan Red is a synthetic red industrial dye, but it is prohibited from being used in food due to its mutagenic and carcinogenic properties. [0003] However, some unscrupulous traders, regardless of national laws, add Sudan red as food coloring to food in order to pursue commercial interests and to make food more beautiful. Chili food is the most common, which has brought great harm to our food safety. Challenge, therefore, it is necessary to detect whether pepper food contains Sudan red. [0004] The traditional detection method is high performance liquid chromatography, which can not only detect the type of Sudan red, but also determine the exact content of each type. However, for the majority of consumers, not only is HPLC too professional and...
