Abstract
The invention discloses a method for preparing idesia oil, which is characterized by comprising the following steps of: filtering crude idesia oil by a filtering cloth to remove mechanical impurities; adding 100 parts of the filtered crude idesia oil into 0.5 to 2.0 parts of degumming agents at 75 to 80 DEG C; stirring for 20 to 35 minutes; cooling and centrifuging to separate the colloid in the lower layer; washing the idesia oil in the upper layer by using deionized water to a neutral state to obtain degummed idesia oil; dehydrating the degummed idesia oil at a vacuum degree of 4000 to 5000 Pa and the temperature of 60 to 80 DEC C for 20 to 30 minutes; continuously deacidifying the dehydrated idesia oil at the temperature of 105 to 130 DEG C, the pressure of 10 to 20 Pa, the feed rate of 80 to 120 mL/h and the film scraper rotation speed of 150 to 200 r/min, wherein the light component is removed free fatty acid, and the heavy component is product oil. The method has the advantages that the colloid and the fatty acid are removed completely, the production period is short, the effective ingredients, such as vitamin E and the like in the grease are effectively remained; the prepared edible idesia oil has the advantages of high yield, high smoke point, stable property in a storage process, no precipitate, and invariant color; and a special deodorization technology is not needed.
Description
Technical field
The present invention relates to a kind of preparation method of edible idesia oil, belong to the processing technique field of edible oil.
Background technology
Root or bark of Nepal Mallotus (Idesia polycarpaMaxim.var.vestita Diels) is a strong wind section root or bark of Nepal Mallotus platymiscium, and deciduous tree is distributed in China Yangtze valley, and especially there is a large amount of wild resources on ground such as Sichuan, Shaanxi.The root or bark of Nepal Mallotus oleaginousness is up to 36-38%, and the individual plant oil offtake is up to 25-30kg, and becomes to reach term 40-50.Idesia oil contains abundant unsaturated fatty acids, is rich in nutritive value, and early stage research and the producing region edible process of local peasant reality has for many years also proved its security.China has a large population to plough and lacks in addition, and the plantation of root or bark of Nepal Mallotus does not occupy cultivated land, and makes full use of the root or bark of Nepal Mallotus resource and helps satisfying the demand of China people to edible oil, alleviates arable land pressure, meets the national strategy requirement.
The general crude oil of producing from oil crops is called crude oil, contain impurity, do not satisfy the daily life needs, some in addition contain harmful material, as the gossypol in the Oleum Gossypii semen, therefore erucic acid in the rapeseed oil etc. need make with extra care the plant standard that reaches to crude oil.Vegetables oil is refining to be needed through coming unstuck depickling, decolouring, operations such as deodorization.
So come unstuck and be also referred to as dephosphorization because the grease colloid is mainly phosphatide, technology has the aquation method to come unstuck at present, acid system comes unstuck, embrane method is come unstuck and enzymatic degumming.The aquation method is to remove a kind of traditional method of gelationus in the grease, hydration degum is to utilize gelationus wetting abilities such as hydrated phospholipid, under agitation hot water is added in the oil, make phosphatide water-swelling cohesion, other colloid in the grease energy absorb oil after the expansion, the solubleness of colloid in oil is reduced, through natural subsidence and separating of oil.Phosphoric acid degumming is not come unstuck or the pH value of regulation system such as hydration degum oil heated phosphoric or citric acid, nonhydratable phosphatide is dissociated, afterwards the phosphatide cooling is added water and make phosphatide form stable liquid crystal under the state at a slow speed, these crystal can fetter sugar and metal ion effectively, precipitate.At present the treating process of idesia oil has often been ignored the importance of coming unstuck, and does not often come unstuck or only carries out hydration degum.
High-acid value grease is if adopt chemical alkali refining or physics distillatory acid stripping method in the present industrial production that certain limitation is arranged.Because the acid value of oil and fat height, the excess alkali consumption that adds in the chemical bases sweetening process is big, alkali with the N-process of free fatty acids in, also saponification a large amount of neutral oils, make refining yield on the low side; The depickling of physical refining water vapor stripping, grease need be handled under the high temperature of long period, influences oil quality, in the grease some effective constituents as: meetings such as VE and sterol are overflowed with the water vapor stripping, have reduced health nutrient value.Molecular distillation technique is that the residence time is short because the material heating temperature is low, and advantages such as Heat stability is good provide approach to the processing of high molecular, high viscosity, heat-sensitive material.Preserve the effective constituent in the grease when adopting the molecular distillation technique separation of free fatty acids, removed the peculiar smell in the grease.
Summary of the invention
The present invention seeks to provide a kind of preparation method of idesia oil at the deficiencies in the prior art, be characterized in idesia oil come unstuck, depickling handles, and obtains colory edible idesia oil.It has the hygienic standard that loss of effective components in yield height, the grease meets national edible oil for a short time.
Purpose of the present invention is realized that by following technology wherein said raw material umber is parts by weight except that specified otherwise.
The preparation method of idesia oil may further comprise the steps:
