Description
Technical field
The present invention relates to a kind of method of refining of edible oil and fat, particularly a kind of method of utilizing the refining camellia oil of tea seed crude oil.
Background technology
The camellia seed is grown in China mountain area, subtropical zone, south and hilly country, the refining camellia oil by using of domestic market supply at present all is the products that follow conventional lines method for refining raw food oil, obtain through the high temperature refining, its degree of purity can be compared with pure water, this oil product of crossing through the high temperature refining treatment, when having removed harmful substance, also cause multiple functional nutrient material contained in the camellia oil to be run off in a large number, this part material that is run off is the bioactivator that human body is had the highly nourishing health care effect.Now, progress along with science and technology, through both at home and abroad many famous edible oil and fat and nourishing healthy scholar studies confirm that in recent years, edible oil is by the refinery practice technical method of existing routine, the a large amount of loss of multiple functional nutrient material that has caused the highly nourishing health care that contains in the camellia seed oil that compares favourably with high-grade edible olive oil of generally acknowledging in the world to be worth, occur making camellia seed oil being worth the problem that always is not so good as generally acknowledged in the world olive oil that embodies, and cause people for a long time edible overrefinement edible oil make human body lack fat-soluble functional nutrient material, a large amount of problems that take place of disease that national multiple functional nutrient thing disappearance is brought have appearred; And on conventional deodorizing technology, also have the harmful substance (as a spot of trans acids and polymer) that can produce some, in fact there is the problem of bringing adverse effect to human body.
For example, a kind of domestic applications number are the method for 200510100247.1 refining camellia oil, its key step is: (1) is got 100 parts of impurity contents by weight percentage and is warmed to 60～70 ℃ less than 0.2% tea seed crude oil, add 0.2～0.3 part of citric acid, stirred 15～20 minutes, then, add 10～15 parts of 65～75 ℃ of water, stirred 8～12 minutes, left standstill 4～6 hours, remove impurity and water; (2) crude oil is at 230～240 ℃, and vacuum is greater than under the 200PA, and steam distillation makes free fatty in the crude oil less than 0.5%; (3) crude oil is in the time of 40～50 ℃, add concentration 15% sodium silicate solution, stirred 8～12 minutes, then, add concentration 8% sodium hydroxide solution, stirred 28～35 minutes, add 70～80 ℃ of water of 10～15 parts of temperature again, left standstill 2～3 hours, and removed water and soap stock, make the crude oil acid number be not more than 0.2MGKOH/G; (4) when 65～75 ℃ of crude oil temperature, add 12～18 parts of 70～80 ℃ of water, left standstill 1～2 hour, remove water, at vacuum-0.095MPA, 100～110 ℃ of temperature, drying, water content is less than 0.5%; (5) the crude oil temperature is raised to 100～110 ℃, adds 3～5 parts of atlapulgites, under vacuum-0.095MPA, is cooled to 75 ℃ after 23～28 minutes, filters; (6) 210～220 ℃ of temperature, vacuum was distilled 40～60 minutes greater than 260PA, got the deodorization camellia oil; (7) the deodorization camellia oil slowly is cooled to 4～5 ℃, the solid fat crystallization, and static pressure filters, and obtains refining camellia oil.
At present, adopt the refining camellia oil of high temperature process can cause in the camellia oil distinctive various functional nutrient materials destroyed, can produce harmful substance and overweight camellia oil distinctive smell simultaneously in process of production.
