Integrated rapid detection tube and method for rapidly detecting purity of sesame oil

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...
