Description

TECHNICAL FIELD

[0001] The application relates to the technical field of garlic oil detection devices, in particular to a water absorption prevention type garlic oil water content detection device. BACKGROUND

[0002] As a common condiment and health food, the quality stability of garlic oil is crucial. The water content is one of the key indicators for measuring the quality of garlic oil. Excessive water content not only promotes the breeding of microorganisms, leading to oil spoilage, but also accelerates the hydrolysis rancidity and oxidation reaction of oil, seriously affecting the shelf life, flavor and edible safety of garlic oil. Therefore, it is of great practical significance to detect the water content of garlic oil in the production process and finished product quickly and accurately. At present, the methods commonly used in the industry for detecting the water content in oil mainly include Karl Fischer method, which is a classic and benchmark method for determining water content and has high accuracy. The principle is to use iodine and sulfur dioxide in pyridine and methanol solution to determine water. However, this method has obvious drawbacks when applied to garlic oil detection. Karl Fischer reagent is extremely sensitive to water in the air. During sampling, weighing and titration, the garlic oil sample is exposed to the environment for a long time. Garlic oil is sticky, and the sampling and transfer process is slow, which easily absorbs water vapor in the air, resulting in a detection result higher than the true value, causing a "false positive" error. Garlic oil contains active sulfur compounds such as allicin, which may have side reactions with iodine and other components in Karl Fischer reagent, interfering with the titration end point judgment and affecting the detection accuracy. This method requires professional chemical analysts, expensive special reagents and complex glassware, and needs thorough cleaning and drying after each detection, which is time-consuming and labor-intensive, and is difficult to meet the requirements of rapid and frequent detection on the production line.
