Device for extracting lipid in complex food sample matrix

Abstract

The invention provides a device for extracting lipid in a complex food sample matrix, belongs to the technical field of food extraction, and solves the problems of single function, low extraction efficiency, complex operation and the like of an existing lipid extraction device. Comprising a drying box, a roll shaft conveyor, a filtering and stirring mechanism and a material injection pump, a standing phase taking tank is arranged at the feeding end of the roll shaft conveyor, a weighing machine and a displayer are sequentially arranged at the discharging end of the roll shaft conveyor, and a first heating box and a second heating box are arranged on the outer side of the filtering and stirring mechanism and the outer side of the standing phase taking tank correspondingly; the first heating box and the second heating box are connected with the air inlet cover through pipelines, the material injection pump is connected between the filtering and stirring mechanism and the standing and phase taking tank through a pipeline, and a material crushing assembly and a material mixing assembly are arranged on the filtering and stirring mechanism. Hot air circulation can be achieved, and energy consumption is low; a complex food sample can be finely crushed and fully mixed with an extracting agent, and stirring mixing, filtering, phase splitting, evaporation drying concentration and weighing of the complex food sample and the extracting agent are achieved.

Description

technical field [0001] The invention belongs to the technical field of food extraction, and relates to a lipid extraction device, in particular to a lipid extraction device in a complex food sample matrix. Background technique [0002] Lipids are the main nutrients in food, mainly including 8 categories: fatty acids, glycerides (including triglycerides, diglycerides, monoglycerides), glycerophospholipids (phosphatidylcholine PC, phosphatidylethanolamine PE, phospholipids) Acyl-inositol PI, phosphatidylserine PS, phosphatidylglycerol PG, phosphatidic acid PA), sphingolipids (ceramide Cer, sphingomyelin SM), glycolipids (ganglioside GM, GD), sterol lipids, Pregnenolone lipids, polyvinyls. Since the concept of lipidomics was proposed in 2003, the importance of food lipidomics for health and disease prevention has gradually been recognized. [0003] When designing various solid and liquid foods, lipid composition is an important aspect of their nutritional function. Especiall...
