Embodiment 1

[0021] A method for eliminating benzopyrene in Camellia oleifera seed oil, comprising the steps of:

[0022] Pump 1000 kg of Camellia oleifera seed crude oil with a benzopyrene content of 50.5 μg / kg into the degumming tank, add 1.5 kg of degumming agent food-grade citric acid, stir at a speed of 50 r / min, degumming temperature of 60 ° C, and degumming time of 60 min. Place for 1 hour, then drain the lower water layer; pump the degummed camellia seed oil into the deacidification tank, add 5kg of food grade NaOH with a concentration of 25%, the temperature is 30°C, the time is 20min, the stirring speed is 100r / min, and then the temperature is raised to 70°C, let it stand for 1 hour, drain the saponins, etc.; wash the oil with 30kg of hot water at 90°C each time, the oil temperature is 85°C, and the stirring speed is 80r / min, until the pH value of the water layer is equal to 7; Camellia oleifera seed oil is pumped into the dehydration tank, heated to 90°C, and the vacuum degree i...

Embodiment 2

[0025] Pump 800 kg of benzopyrene content of 50.5 μg / kg camellia seed oil crude oil into the degumming tank, add 1.0 kg of degumming agent food grade citric acid, stirring speed is 90r / min, degumming temperature is 30°C, degumming time is 120min, let stand 1 hour, then discharge the lower water layer; the camellia seed oil after degumming is pumped into the deacidification tank, adding 4.0kg concentration is 25% edible grade NaOH, temperature 10 ℃, time 50min, stirring speed is 150r / min, then heat up to 70°C, let it stand for 1 hour, drain the saponins, etc.; wash the oil with 50kg of water, 50°C hot water, the oil temperature is 60°C, and the stirring speed is 80r / min, until the pH value of the water layer is equal to 7; the washed camellia seeds The oil is pumped into the dehydration tank, the temperature is raised to 100° C., and the vacuum is 0.08 MPa for drying and dehydration; the dehydrated camellia oleifera seed oil is pumped into the decolorization tank, and 15 kg of a...

Embodiment 3

[0028] Pump 1000 kg of camellia seed oil crude oil with a benzopyrene content of 50.5 μg / kg into the degumming tank, add 5.5 kg of degumming agent food-grade citric acid, stir at a speed of 150 r / min, degumming temperature of 40 ° C, and degumming time of 80 min. Place for 1 hour, then drain the lower water layer; pump the camellia seed oil after degumming into the deacidification tank, add 6kg concentration of 25% food grade NaOH, temperature 20°C, time 40min, stirring speed is 30r / min, then heat up to 70°C, let it stand for 1 hour, drain the saponins, etc.; wash the oil with 30kg of hot water at 85°C each time, the oil temperature is 80°C, and the stirring speed is 80r / min, until the pH value of the water layer is equal to 7; Camellia oleifera seed oil is pumped into the dehydration tank, heated to 80°C, and the vacuum degree is 0.098MPa for drying and dehydration; the dehydrated camellia oleifera seed oil is pumped into the decolorization tank, and 30kg of activated carbon a...

Abstract

Provided is a method for removing benzopyrene in oil-tea camellia seed oil. Crude oil-tea camellia seed oil with benzopyrene exceeding the standard serves as a raw material, by means of the processes including degumming, deacidification, washing, adsorption and deodorization refining, particularly selection and control of an adsorbent, benzopyrene in the original oil-tea camellia seed oil with benzopyrene exceeding the standard can be removed or reduced to meet the requirement of national standard. The method for removing benzopyrene in oil-tea camellia seed oil is simple and practical and can remarkably reduce content of benzopyrene in the oil-tea camellia seed oil, and extra refining equipment is not needed.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a method for eliminating benzopyrene in camellia oleifera seed oil. Background technique [0002] Camellia oleifera belongs to the family Theaceae Camellia, and is known as the world's four major woody oil plants together with olive, oil palm, and coconut. It originated in China and has a history of cultivation and utilization for more than 2,000 years in my country. It is mainly distributed in the Yangtze River Basin and its south 14 provinces (autonomous regions, municipalities) of China. [0003] Camellia oleifera seed oil is the oil obtained by pressing or extracting camellia oleifera. The chemical composition and fatty acid ratio of camellia oleifera seed oil are similar to olive oil, and some indicators are higher than olive oil. It is known as "Oriental olive oil". Tea seed oil is resistant to storage, not easy to rancidity, does not produce carcinogenic aflatoxin, and is ric...
