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
Idesia (Idesia polycarpaMaxim.var.vestita Diels) is a strong wind section idesia platymiscium, and deciduous tree is distributed in China Yangtze river basin, and especially there is a large amount of wild resources on ground such as Sichuan, Shaanxi.The idesia oil content is up to 36-38%, and the individual plant oil production is up to 25-30kg, and becomes to reach term 40-50.Idesia oil contains abundant unrighted acid, 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 idesia does not occupy cultivated land, and makes full use of the idesia 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 from oil crops, producing is called crude oil; Contain impurity; Satisfied not the daily life needs, some in addition contain harmful material, like the gossypol in the cottonseed oil; Therefore erucic acid in the rapeseed oil etc. need make with extra care the plant standard that reaches to crude oil.Vegetable 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 conventional method of colloid in the grease; Hydration degum is a hydrophily of utilizing colloids such as hydrated phospholipid; Under agitation hot water is added in the oil, make phosphatide imbibition cohesion, the grease after the expansion can adsorb other colloid in the grease; The solubility of colloid in oil is reduced, separate with oil through natural subsidence.Phosphoric acid degumming is with not coming 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 subtractive 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 the acid stripping method of chemical alkali refining in the present commercial production of employing or physics distillation has certain limitation.Because acid value of oil and fat is high, the excess alkali consumption that adds in the chemical bases sweetening process is big, alkali with the N-process of free fatty in, also saponification a large amount of neutral oils, make refining yield on the low side; The depickling of physical refining water vapour stripping, grease need be handled under the high temperature of long period, influences oil quality, in the grease some active ingredients as: meetings such as VE and sterol are overflowed with the water vapour stripping, have reduced health nutrient value.Molecular distillation technique is that the holdup time is short because the material heating temperature is low, and advantages such as Heat stability is good provide approach to the processing of HMW, high viscosity, heat sensitive material.Preserve the active ingredient 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 to the deficiency of prior art, be characterized in idesia oil come unstuck, depickling handles, and obtains colory edible idesia oil.It has the sanitary standard that loss of effective components in yield height, the grease meets national edible oil for a short time.
The object of the invention realizes 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:
(1), preliminary treatment
