Description

Technical Field

The invention relates to the technical field of food detection, in particular to a pretreatment device for identifying the quality of chafing dish oil.

Background

The hotpot condiment needs a large amount of grease in the boiling and boiling processes, and the beef tallow has special grease flavor, so that the beef tallow can increase the flavor of the hotpot and improve the rinsing taste in the frying and boiling processes, and therefore, most of traditional hotpot condiment in ChuanYu areas mainly comprises beef tallow. However, the beef tallow has higher saturated fatty acid, and is not good for human health when being eaten in large quantity, so that the improvement of the health quality of the beef tallow by controlling the fatty acid composition is widely applied. The improvement methods mainly comprise the following steps: selecting beef tallow in specific regional environment, feeding conditions and specific part adipose tissues; adopting different grease raw materials for compounding; improving the oil refining process and the like. Therefore, the production of the hot pot beef tallow with higher healthy quality inevitably generates higher production cost, and in order to prevent the problem of adulteration in the market, which is caused by inferior quality (lower healthy quality is used as higher healthy quality), the fatty acid composition of the hot pot beef tallow needs to be effectively identified.

At present, for the detection of fatty acid in grease, a detection method allowed by national standards is gas chromatography, and before entering a gas chromatograph for analysis, appropriate and effective sample pretreatment needs to be performed, such as procedures of fatty saponification, fatty acid methyl esterification, supernatant extraction, and the like.
