Abstract
The invention discloses a method for extracting camellia oil by using a microwave assisted aqueous extraction method, belonging to the technical field of grease preparation. In the method, dried tea seeds are husked, baked, crushed and ground and then are subjected to water feeding, microwave extraction, centrifugal separation, emulsion breaking, washing and vacuum dehydration to obtain the camellia oil. The method has the advantages of simpleness in process operation, favorable grease quality, high extraction speed, high extraction rate, less pollution to the environment and low cost and is suitable for industrial scale production.
Description
Technical field
The present invention relates to grease preparation technique field, specifically is a kind of microwave-assisted water extracts Camellia oil for method method.
Background technology
Tea seed is one of the world's four big woody oleiferous plants, mainly is distributed in China Jiangxi, Hunan, Anhui, Guangxi Si Sheng, and is maximum with the Hunan.Camellia oil is through the grease that squeezes or lixiviate obtains with camellia seed kernel, according to the literature, the camellia oil colours perfume (or spice) of distinguishing the flavor of clearly, unsaturated fatty acids during its lipid acid is formed---oleic acid and linoleic content is up to 83%～90%, the long-term edible diseases such as arteriosclerosis, hypertension and obesity that help preventing.Have good reputations such as " east sweet oil ", " treasure in the oil ".
In the main producing region of China's tea seed, main at present employing milling process and lixiviation process are produced tea oil.The workshop-based squeezing process of most employings, not only the cost height, to go out rate low, and contain more recuding sugars in the tea seed, in expressing process, grease color is deepened, made the oil quality difference and price is not high, purposes is restricted and its squeeze cake also is difficult to utilize because of being subjected to high temperature that brown stain easily takes place.Also have factory to adopt lixiviation process, but the organic solvent that adopts is volatile, is difficult to satisfy requirement of safe production for midget plant, easy residual solvent in cost height, the big for environment pollution and processed oil, even carcinogens exceeds standard, the harm human consumer is healthy.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of microwave-assisted water extracts Camellia oil for method method.
This microwave-assisted water of the present invention comprises following processing step for the method for method extraction Camellia oil:
A, peel off: adopt disk huller that dried tea seed shell is smashed, benevolence, shell are separated, the tea seed shell is thinner, and moisture is lower after drying, is easy to fragmentation;
B, bake: the camellia seed kernel after will peeling off bakes 15～30min at 160～280 ℃, makes the cohesion of protein receptor thermally denature, gathers together after tiny oil droplets in the cell is heated and be distributed in, and helps fuel-displaced;
C, pulverize defibrination: the camellia seed kernel after will peeling off is pulverized and is ground to granularity＜10 μ m, and the pulpous state liquid behind the mill is based on oil, and its suspension can emulsification;
D, add the water microwave extracting: the tea seed slurry that will pulverize after grinding is 1: 3～5 uniform mixing with water by mass ratio, the heated and stirred extraction, and 60～70 ℃ of extraction temperature are under the microwave-assisted of 800W at power, extraction time 30～45min;
E, centrifugation: adopt the spiral shell settling centrifuge that crouches to isolate oil in water emulsion and albumen screenings, separate the albumen screenings that obtains and behind concentrate drying, can be used as the animal feed protein powder;
F, breakdown of emulsion-washing-dehydration: the oil in water emulsion that separation is obtained adds 10～20% hot washes, centrifugation removes freight, obtains Camellia oil after the vacuum hydro-extraction after stirring breakdown of emulsion.
The method that this microwave-assisted water provided by the invention extracts Camellia oil for method is different with traditional milling process, lixiviation process oil-producing technique: water for method with water as medium, realize oily water separation, wholely put forward oily process and be equivalent to the process that oil has passed through " washing ", removed impurity and the peculiar smell in the Camellia oil.Nowadays the exuviating technology of tea seed has been realized mechanize, and camellia seed kernel oleaginousness height, belongs to soft oil plant, is suitable for oil extraction by water substitution.Advantages such as microwave is a kind of frequency electromagnetic waves, and the microwave auxiliary extraction Camellia oil has that extraction rate is fast, grease extraction yield height, solvent consumption are few.Adopt microwave-assisted water to extract the requirement that Camellia oil meets " safety, nutrition, green " fully, and technological operation oil quality simple, that extract is good, low in the pollution of the environment, cost is low for method.
Description of drawings
Accompanying drawing extracts the technological process of production figure of Camellia oil method for method for microwave-assisted water of the present invention.
Embodiment
By accompanying drawing as can be known, adopt disk huller that dried tea seed shell is smashed, benevolence, shell are separated, the camellia seed kernel after peeling off bakes 30min at 180 ℃, pulverizes then and is ground to granularity＜10 μ m.Is 1: 4 uniform mixing with water by mass ratio with the tea seed slurry of pulverizing after grinding, and in 70 ℃ of heated and stirred extractions of temperature, power is under the microwave radiation of 800W, extractive reaction 30min.The extraction liquid that reaction obtains adopts the spiral shell settling centrifuge that crouches to isolate oil in water emulsion and albumen screenings.In oil in water emulsion, add after emulsion splitter stirs breakdown of emulsion, add 10% hot wash, centrifugation removes freight, obtains Camellia oil after the vacuum hydro-extraction.The method that adopts microwave-assisted water to extract Camellia oil for method has that technological operation is simple, by product is few, extraction rate is fast, solvent consumption is few, the environmental pollution degree is low, and the Camellia oil that extracts is best in quality, extraction yield is than characteristics such as height, is fit to scale operation.
