Problems solved by technology

[0005] In the leaching process, the content of benzo(a)pyrene in sesame crude oil is relatively high, which mainly comes from the machine-pressed cake; while in the refining process, although it has gone through deacidification, decolorization, degumming, deodorization, filtration and other processes, However, the content of benzo(a)pyrene has hardly decreased, so the content of benzo(a)pyrene in sesame oil is still high, exceeding the requirements of national standards

Embodiment Construction

[0014] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention

[0015] A process for removing benzo(a)pyrene in sesame oil, the process method is as follows:

[0016] 1). Using the pressing method to make oil, the sesame seeds are screened, roasted, steamed and pressed, filtered once, naturally settled, and filtered twice to obtain sesame oil;

[0017] 2). Weigh about 100g of sesame crude oil or finished sesame oil into a clean container;

[0018] 3). Put the container in a constant temperature water bath. When the oil temperature reaches 80°C, add 1g of activated carbon or activated clay, stir ...

Abstract

The invention discloses a process for removal of benzo (a) pyrene in sesame oil. The optimal technological conditions for the production of refined sesame oil are as below: 1% of white clay and 0.8%of activated carbon; adsorption time of 45min; and adsorption temperature of 80 DEG C. the production of light sesame oil product needs secondary adsorption. The optimal conditions as below: 5% of white clay and 0.8% of activated carbon. Under the optimal technological conditions, the finished product of sesame oil has benzo (a) pyrene content reaching the national standard of 10 mug / kg, but does not reach the EU standard of 2.0 mug / kg. Therefore, the activated carbon is used for re-adsorption on the refined sesame oil; and the results show that the finished product of sesame oil has benzo (a) pyrene content reaching the EU standard of no more than 2.0 mug / kg.

Description

technical field [0001] The invention relates to a process for removing benzo(a)pyrene in sesame oil. Background technique [0002] Benzo(a)pyrene is one of the three recognized carcinogens in the world. It has strong carcinogenicity and is closely related to our diet. Studies have shown that vegetable oil itself does not contain or rarely contains benzo(a)pyrene, but it is often contaminated during planting, processing, transportation, storage and cooking. Understanding the structure and properties of benzo(a)pyrene, the way to control the source of benzo(a)pyrene in vegetable oil, and mastering the detection method of benzo(a)pyrene in food are extremely important for ensuring food safety and protecting human health significance. [0003] The sources of benzo(a)pyrene in edible oils and fats include: processing pollution, raw material pollution and environmental pollution, among which the main source is from food processing, such as smoking, roasting, cooking, etc., which...
