The process disclosed by the invention is simple, environmental pollution caused by alkali refining and deacidification and damages to bioactive substances and nutritional components in traditional steam heating and deodorization can be avoided, and the quality and health-care function of finished product tea oil can be further improved.
Description
Technical field
The present invention relates to a kind of deacid-deodoring method of tea oil, be specifically related to a kind of method that adopts the CO 2 fluid abstraction technique tea oil crude oil to be carried out depickling and deodorization.
Background technology
Tea oil is the woody grease that obtains from Theaceae tea oil tree seed, has another name called tea-seed oil, Camellia oil, is the distinctive woody grease of China.Tea oil mainly is comprised of unsaturated fatty acidss such as oleic acid, linolic acid, palmitinic acid and linolenic acid, with universally acknowledged quality plant grease---and the composition composition of sweet oil is closely similar, and the physics-chem characteristic of tea oil is also closely similar with sweet oil.Tea oil has the blood vessel elasticity of enhancing and toughness, delays atherosclerosis, increases the stomach absorptive function, promotes internal secretion body of gland hormone secretion, prevents that neural function from descending, and improves the effects such as body immunity.In recent years, along with the improvement of diet formula, the enhancing of people's health care consciousness, the favor that tea oil obtains the human consumer with its abundant nutrition and function, development is rapidly.
For a long time, China's tea oil is to produce crude oil with two kinds of methods of mechanical expression and extraction, crude oil again through coming unstuck, the techniques such as depickling, dehydration, decolouring and deodorization, obtain refining tea oil.Traditional tea oil process for refining has the destruction of biologically active substance and nutritive ingredient in complex process, the tea oil and loss is large, use the alkali depickling easily to cause shortcomings such as there being dissolvent residual in environmental pollution and the product.Occurred in recent years utilizing supercritical carbon dioxide extraction technology from tea seed, to extract the method for tea oil, the method is more common in each journal and patent document, be the patent of invention " a kind of working method of edible camellia oil " of CN101194713B such as publication number, the production method that proposes edible camellia oil is, adopt supercritical carbon dioxide extraction method from tea seed, to extract tea oil, through coming unstuck and alkali-refining deacidification, obtain refining tea oil again.Supercritical carbon dioxide extraction tea oil from tea seed can be simplified refining procedure, improves the tea oil quality, and value has additional nutrients.But because the raw material that the method is processed is solid, extraction process relates to higher pressure, the loading and unloading of solid materials become a very large problem, thereby cause that overcritical facility investment is large, extraction cost is high, brought very large resistance for the industrialization practical application of supercritical carbon dioxide extraction process.The notable difference of solubleness in CO 2 fluid based on tea oil free fatty acid and the compositions such as stink substance and triglyceride level.We propose the tea oil crude oil with the production of the methods such as mechanical expression or extraction, adopt CO 2 fluid (comprising supercritical carbon dioxide fluid, subcritical CO 2 fluid and Liquid carbon dioxide) abstraction technique to carry out the tea oil purification techniques of depickling and deodorization processing.
Summary of the invention
The object of the present invention is to provide a kind of new tea oil deacid-deodoring method, transform conventional tea oil refining technique, the destruction of biologically active substance and nutritive ingredient in the minimizing refining process, quality and its nourishing function of raising finished product tea oil, the environmental pollution of avoiding traditional alkali-refining deacidification to cause.
To achieve these goals, the present invention has adopted following technical proposal:
By CO 2 fluid extraction or CO 2 fluid counter-current extraction tea oil being carried out deacid-deodoring processes.
The concrete mode that CO 2 fluid extraction tea oil deacid-deodoring is processed is: the tea oil crude oil is put into extraction kettle, pass into carbonic acid gas and extract, extraction conditions is: extraction temperature 20-70 ℃, and extracting pressure 7-30MPa, separating still I pressure 5-15MPa, 30-80 ℃ of separating still I temperature, separating still II pressure 4-7MPa, 30-50 ℃ of separating still II temperature, extraction time 10-240min, collect raffinate oil and extract, the acid number of refining rear tea oil is 0.1-3mgKOH/g, and stink obviously alleviates.
The concrete mode that CO 2 fluid counter-current extraction tea oil deacid-deodoring is processed is: the tea oil crude oil is pumped into the counter-current extraction post from counter-current extraction post top, pass into carbonic acid gas from counter-current extraction post bottom and carry out counter-current extraction, extraction conditions is: extraction temperature 20-70 ℃, extracting pressure 7-25MPa, separating pressure 4-8MPa, separation temperature 30-50 ℃, can carry out continuous extraction, collect raffinate oil and must make with extra care tea oil, the acid number of refining rear tea oil is 0.1-3mgKOH/g, and stink obviously alleviates.
Present method compared with prior art has following advantages and effect:
(1) depickling and deodorization are carried out simultaneously, and technique is simple;
(2) alkali is not used in present method depickling, the environmental pollution of having avoided traditional alkali-refining deacidification to cause;
(3) present method can be avoided the destruction of biologically active substance and nutritive ingredient in traditional steam heating deodorization, improves quality and its nourishing function of finished product tea oil;
(4) select nontoxic carbonic acid gas as extraction solvent, do not have hazardous solvent residual.
