Abstract
The invention relates to a method for processing cold-pressed walnut oil, belonging to the technical field of production of edible oil. The method comprises the following steps: hydraulically cold-pressing, spirally cold-pressing, roughly filtering, charging nitrogen and refined-filtering. The method has the beneficial effects that nutritional ingredients in walnut can be effectively preserved so that the walnut oil obtained through production is stable in quality and rich in nutrients.
Description
Technical field
The present invention relates to the edible fat production technical field, be specifically related to a kind of working method of cold press walnut oil.
Background technology
Walnut, belong to Juglandaceae deciduous tree dry fruit, is listed in one of the world's four large nuts, mainly is distributed in America, Europe and Asia.In China, also have and plant widely and apply, because of its abundant nutritive value, by increasing people, praised highly.
In walnut kernel, contain abundant walnut oil, in walnut oil, contain abundant unsaturated fatty acids, the trace elements such as multivitamin and calcium, iron, magnesium, can be used for health care, is a kind of xylophyta oil of high nutrition, has been subject to liking of consumers in general.
Existing method of producing walnut oil mainly contains following several: the high temperature pressing method that (1) is traditional; Because the walnut oil unsaturated fatty acid content is high, high temperature can accelerated oxidation become sour, and causes oil product defective.(2) for removing taste pained in walnut oil, add to remove bad mouthfeel into various additives, also can remove the nutritive ingredient in walnut oil simultaneously, cause nutritive ingredient seriously to run off, and productive rate is lower.(3) adopt solvent to extract, can make in oil product to have dissolvent residual, have potential safety hazard.
Summary of the invention
The working method that the purpose of this invention is to provide a kind of cold press walnut oil, can make the stay in grade of walnut oil, nutritious, can also improve productive rate.
The technical solution used in the present invention is a kind of working method of cold press walnut oil, comprises the following steps:
A, hydraulic cold: walnut kernel is placed in hydraulic oil press equipment, and at room temperature pressurization, treat that pressure is to 15kg/cm
2～25kg/cm
2The time, pressurize is fuel-displaced, then is forced into 35kg/cm
2～45kg/cm
2, pressurize is fuel-displaced, obtains slubbing pressed oil and the dregs of fat;
B, spiral cold press: the described dregs of fat are pulverized, then be placed in Spire oil manufacturing device, extruding ，De bis-road pressed oils;
C, coarse filtration: collect described slubbing pressed oil and two road pressed oils, filter, obtain just oil strain;
D, fill nitrogen: described just oil strain is placed under vacuum condition, fills nitrogen, standing;
E, essence filter: adopt 5 μ m～25 μ m fine filtering devices to filter, obtain finished product.
As preferably, the granularity of pulverizing in described step b is 3mm.
As preferably, in described step c, coarse filtration adopts the Plate Filtration device to filter, filter pressure≤3.5kg/cm
2.
As preferably, in described steps d, the standing time is 7～10 days.
As preferably, in described step e, fine filtering device is that filter screen is the vertical secondary filter of 10 μ m.
The invention has the beneficial effects as follows:
(1) can effectively guarantee the quality of walnut oil, meet the related request of GB22327-2008; And can effectively retain the nutritive ingredient in walnut kernel, make in walnut oil to be rich in unsaturated fatty acids and abundant trace element etc.
(2) can improve the yield of walnut oil, its yield is about 80%, compares existing approximately 50% yield and has improved a lot.
(3) walnut oil that adopts working method of the present invention to obtain, the delicate fragrance nature, mouthfeel is good, without pained taste, can directly add in cold dish to eat or be used to dipping in food.
(4) working method of the present invention, craft science is reasonable.Whole oil expression process is carried out under normal temperature condition, can guarantee that oil product can oxidizedly not become sour, and has avoided because adopting conventional high temperature squeezing process, and the impurity such as the colloid in walnut kernel are blended in oil product, thereby have simplified complete processing.In another the present invention's processing, adopted and filled nitrogen technique, can guarantee the oil product standing storage, can be not oxidized.By complementing each other of each technique, realized simplification technique, also kept simultaneously the oil product high-quality of walnut oil, good mouthfeel.
