Embodiment 1

[0015] Example 1. An integrated rapid test tube for rapid detection of the purity of sesame oil: Weigh 1g of sucrose, dissolve it in 10mL of concentrated hydrochloric acid with a concentration of 36%-38%, and then use concentrated hydrochloric acid to make it to 100mL, and take 1mL to make it to volume The solution was dispensed into the speed test tube.

[0016] The method of quickly detecting the purity of sesame oil with an integrated rapid test tube: take 0.1mL of a sesame oil sample and add it to the above-mentioned sesame oil purity rapid test tube, shake well, wait for a 5-minute reaction time, and determine the purity of the sample sesame oil according to the discoloration of the rapid test tube.

Embodiment 2

[0017] Embodiment two, do standard addition experiment with pure sesame oil.

[0018] Use sesame oil with a purity of 5%, 10%, 30%, 50%, 80%, and 100% respectively, and test according to the method in Example 1.

[0019] Sesame Oil Purity 5% 10% 30% 50% 80% 100% Color rendering basically colorless light red light red Pink red dark red

[0020] Color development results: sesame oil with a purity of 5% is basically colorless; sesame oil with a purity of 10% is light red; sesame oil with a purity of 30% is light red; sesame oil with a purity of 50% is pink; sesame oil with a purity of 80% Red; 100% pure sesame oil is dark red. It can be seen from the above structure that the detection limit of the kit of the present invention is 5%.

[0021] In summary, the present invention is suitable for sesame oil, which improves the versatility and detection efficiency. The present invention is simple in operation, high in sensitivity, applicable in tech...

Abstract

The invention discloses an integrated rapid detection tube and method for rapidly detecting the purity of sesame oil, which relate to the field of the purity of sesame oil. The integrated rapid detection tube for rapidly detecting the purity of sesame oil is prepared by the following steps of weighing 1g of cane sugar, dissolving the cane sugar in 10 mL of concentrated hydrochloric acid, fixing the volume to 100 mL by using the concentrated hydrochloric acid, and sub-packaging 1 mL of the solution with the fixed volume into the rapid detection tubes, adding 0.1 mL of a sesame oil sample into the sesame oil purity rapid detection tube, uniformly shaking, waiting for 5 minutes of reaction time, and judging the purity of the sesame oil sample according to the color change condition of the detection tube. The method is suitable for the sesame oil, improves universality and detection efficiency, is simple to operate, high in sensitivity, applicable in technology, environment-friendly and safe, can perform field detection, does not need instrument assistance, conforms to related principles and requirements of popularization and application, can be directly operated by simple training or according to a specification, does not need professional technicians, and is short in detection time, high in efficiency, and low in cost. The detection limit is 5%, and the detection blank of the sesame oil purity in the market can be filled.

Description

technical field [0001] The invention relates to the field of detection of the purity of sesame oil, in particular to an integrated rapid detection tube and method for rapidly detecting the purity of sesame oil. Background technique [0002] In recent years, the phenomenon of sesame oil adulteration has become more serious. In order to make huge profits and disregard the interests of consumers, some criminals have mixed sesame oil with other edible oils (rapeseed oil, soybean oil, salad oil, etc.) , Not only harmed the vast number of consumers, but also disrupted the order of the market economy. [0003] The main components of sesame oil are unsaturated fatty acids, accounting for 85%-90%, oleic acid and linoleic acid basically each account for 50%, and also contain protein, sesamin, vitamin E, lecithin, sucrose, calcium, phosphorus, iron and other minerals. Unsaturated fatty acids in sesame oil can promote cholesterol metabolism, eliminate deposits on arteries, and can eff...
