Abstract
The invention discloses an extracting process regulating grease ratio of colza oil, comprising: drying the water content of rapeseed to 5-15%, adding into an extruding bulking machine to extrude grease, and forming the rapeseed into grains; adding the grains into water, heating, adding composite enzyme, and stirring for reaction; heating to destroy the enzyme, filtering, and collecting filter slag; adding water into the filter slag for leaching, heating and stirring, then centrifuging to separate oil, sewage and solid sediment; combining obtained oil with the grease in step (1) to obtain grease. By controlling the water content of the rapeseed and extracting process parameters, the process improves the ratio of linoleic acid to linolenic acid in the grease obtained by extruding, and improves nutrient value of the grease. According to the extracting process, the rapeseed is not required to be peeled, no organic solvent is adopted in the whole process, the obtained grease is safe, and a process route is green and environment-friendly and high in grease yield.
Description
Technical field
The invention belongs to fundamentals technical field, be specifically related to a kind of regulate and control the squeezing process of rapeseed oil grease ratio.
Background technology
Semen Brassicae campestris is because becoming one of important oil crops in the world and China containing abundant grease and amino acid form excellent protein.According to FAO (2002) statistics, in whole world oil crops, Semen Brassicae campestris output is only second to soybean, palm and cottonseed, occupies the 4th.First of the rapeseed cultivation area of China and the current Jun Ju world of output.In order to make full use of this high-quality resource of Semen Brassicae campestris, the highly-efficient processing of countries in the world to Semen Brassicae campestris utilizes technology all to expand extensive and deep research.
Rapeseed peeling cold press bulking process remains the emphasis of countries in the world research, and current decortication technology solves substantially, but after decortication, the cold-squeezing of material is still the difficult point of research.Main because material oleaginousness is high after decortication, content of cellulose reduces.In squeezing grease process, the high crude fiber content of seed coat both can increase the porosity squeezing material matrix in squeezing thorax, was convenient to the infiltration of grease, can increases rubbing factor again, was conducive to squeezing the conveying of material in squeezing thorax.After vegetable seed decortication, the physical property of material, as rubbing factor, perviousness etc., great changes will take place, is unfavorable for that oil is got in squeezing; Secondly, the rapeseed dehulled after decortication is when cold press, and enter machine oil material and do not carry out the pre-treatment such as any heating and strip plate, cell wall damage degree is little, and the avidity of lipid body and protein is still very strong, is unfavorable for that grease is squeezed out.Therefore, oil is got in the cold press needing the structure changing existing screw oil expeller could realize rapeseed dehulled.
The rapeseed Processing technique generally adopted at present is pre-pressing extraction technology, only has at some small-sized oil-fat plants and adopts milling process to get oil; Because the rate of recovery of pre-pressing extraction technology grease can more than 96%, and squeezing process oil recovery rate only has 80% usually.But more and more higher along with what require aspects such as environment and safety in recent years, not extractive technique is with an organic solvent received much concern.If organic solvent can not be adopted can to obtain the oil recovery rate close with organic solvent extraction technology, then the technology not adopting organic solvent will be more competitive.
Summary of the invention
The object of this invention is to provide a kind of regulate and control the squeezing process of rapeseed oil grease ratio, by controlling water content and the squeezing process parameter of rapeseed oil, improving the grease obtained Linoleic acid of squeezing and linolenic ratio, improving the nutritive value of grease.
To achieve these goals, the technical solution used in the present invention is:
Regulate and control a squeezing process for rapeseed oil grease ratio, comprise the steps:
1) Semen Brassicae campestris being dried to water ratio is 5 ~ 15%, adds in extruder and extrudes, extrude and obtain grease, and Semen Brassicae campestris forms material grain through extruding;
2) material grain step 1) obtained is added to the water, and is warming up to 25 ~ 40 DEG C, adds prozyme, with the rotating speed stirring reaction 1 ~ 3h of 120 ~ 150rpm; Be warming up to 90 ~ 100 DEG C, go out enzyme 5 ~ 10min, filters, and collects filter residue;
3) to step 2) filter residue in add flooding, be warming up to 50 ~ 70 DEG C, stir 1 ~ 3h, then centrifugation obtains oil, waste water and solid phase precipitation, is merged by the grease in the oil of gained and step 1), obtains grease.
In step 1), Semen Brassicae campestris is dried to water ratio is 8 ~ 12%.
Step 2) described in prozyme be cellulase, polygalacturonase and proteolytic enzyme (1 ~ 10) in mass ratio: 1:(1 ~ 10) be composited.
Step 2) in every 1g expect the water adding 1 ~ 5mL in grain.
Step 2) expect that grain is added to the water, be warming up to 30 DEG C.
Step 2) in add after prozyme with the rotating speed stirring reaction 2h of 130rpm.
The water of 1 ~ 5mL is added in every 1g filter residue in step 3).
Be warming up to 60 DEG C in step 3), stir 2h.
Rotating speed centrifugal in step 3) is 12000 ~ 18000rpm.
Beneficial effect:
Provided by the invention a kind of regulate and control the squeezing process of rapeseed oil grease ratio, by controlling water content and the squeezing process parameter of rapeseed oil, improving the grease obtained Linoleic acid of squeezing and linolenic ratio, improving the nutritive value of grease.
Squeezing grease technique of the present invention, without the need to carrying out decortication process to Semen Brassicae campestris, do not adopt organic solvent, grease obtained safety, operational path environmental protection, and grease yield is high in whole technique.
The water ratio of the Semen Brassicae campestris of drying after usually receiving is about 10%, and the Semen Brassicae campestris of results can directly be squeezed by present invention process, without the need to pretreatment technology, cost-savingly improves oil yield simultaneously.
Semen Brassicae campestris first adds in extruder and extrudes by the present invention, and while extruding part grease, Semen Brassicae campestris forms material grain through extruding, and material grain is by ferment treatment, and can improve oil yield, the setting of this step instead of traditional grinding steps, simplifies the operation further.
