A processing technology for reducing benzopyrene content in refined oil during sesame frying

Abstract

The invention discloses a processing technology for reducing the content of benzopyrene in finished oil during sesame frying. Step 1, frying sesame: pour sesame into frying equipment for frying process, and start the spin-off during the frying process. A dust removal device and a fan at the bottom thereof, the fan extracts smoke generated in the frying equipment through an air intake pipe at the top of the frying equipment, and the invention relates to the technical field of food processing. The processing technology for reducing the content of benzopyrene in the refined oil during the sesame frying process is to heat-treat the sesame by setting multiple sets of equipment such as frying equipment, feeding hopper, material receiving mechanism and layered smoke exhaust device, and cooperate with the intake pipe to reduce the benzopyrene content. The smoke generated after the sesame is fried is pumped out, which can remove most of the benzopyrene in the smoke, thereby reducing carcinogens, and by setting the heat recovery pipe, the heat in the discharged hot smoke can be recovered , reducing the waste of heat, and the recovered heat can be used for heat preservation and heating of sesame, which is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing technique for reducing the content of benzopyrene in refined oil in the process of frying sesame. Background technique [0002] Benzopyrene is a condensed aromatic hydrocarbon containing a benzene ring. The fused position of the benzene ring is different, and benzopyrene is divided into two types: the common 1,2-benzopyrene (also called 3,4-benzopyrene) is a sheet crystal, CAS number: 50-32-8, Melting point 178~179℃, carcinogenic; another 4,5-benzopyrene is yellow crystal, CAS number: 192-97-2, melting point 179~179.3℃, has strong carcinogenicity, protein, fat, carbohydrate This carcinogen is produced when it is charred, so be careful when cooking food. Benzopyrene is insoluble in methanol and ethanol, insoluble in water, and easily soluble in organic solvents such as benzene, toluene, xylene, acetone, ether, chloroform, and dimethyl sulfoxide. It was orig...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a processing technology for reducing the content of benzopyrene in the finished oil during sesame frying, which solves the problem that smoke will be generated during the frying process of sesame, and a large amount of benzopyrene will be contained in it. Pyrene, after being incorporated into sesame oil, will affect food safety, and if the smoke is removed by blowing, the temperature of sesame will be reduced, affecting the output of oil extraction, and a large amount of heat will be exhausted with the smoke, which is also a wasteful problem
