Adulterated peanut oil detector and adulterated peanut oil detection method

Abstract

The present invention provides an adulterated peanut oil detector and an adulterated peanut oil detection method, and pertains to the technical domain of product analysis. The detector comprises a casing, a LCD and Return key, Enter key, Up key, Down key, a power switch, a power socket, and a USB interface arranged on the casing, and a microprocessor and a power supply unit mounted in the casing and electrically connected to the components on the casing, wherein, a module cover is arranged on the top surface of the casing, and a pretreatment module and a detection module are mounted in the space under the module cover. The pretreatment module comprises a heating body and cuvette slots, and the detection module comprises an axial fan, a radiating plate, a refrigerating plate, and cuvette slots. The detection method comprises sample preheating procedure and slow refrigeration procedure. The detector and method provided in the present invention can quickly and easily detect whether the peanut oil sample is adulterated and the percentage of adulteration, and is applicable to quick on-spot detection of rapeseed oil, sunflower oil, maize oil, cotton oil, palm oil, and soybean oil, etc. admixed in peanut oil.

Description

FIELD OF THE TECHNOLOGY[0001]The present invention pertains to the technical domain of product analysis, and relates to an easy-to-use, sensitive, and quick on-spot adulterated peanut oil detector, in particular to an analytical apparatus and a detection method for quickly detecting rapeseed oil, sunflower oil, maize oil, cotton oil, palm oil, and soybean oil adulterated in peanut oil on the spot.BACKGROUND TECHNOLOGY[0002]Peanut oil is famous for its rich nutrients, and is one of edible oil products sold at the highest price among edible oil products in the market. Under normal conditions, peanut oil is in light-yellow, transparent, and clear color and luster, with aromatic smell and delicious taste, and is an edible oil product easy to digest. Peanut oil contains unsaturated fatty acids at 80% or higher percentage (including 41.2% oleic acid and 37.6% linoleic acid). In addition, peanut oil contains saturated fatty acids such as palmic acid, stearic acid, and arachidic acid. Moreo...
