Problems solved by technology

Different types of adsorbents have their own advantages and disadvantages. Using a single adsorbent cannot meet the decolorization requirements. Two or more adsorbents are reasonably selected to make a mixed decolorant in order to obtain the best decolorization effect most economically.

Embodiment 1

[0016] A method for decolorizing medicinal raw material grade Camellia oleifera seed oil, comprising the following steps:

[0017] A. The preparation of the decolorizing agent comprises the following steps: (1) mixing clay and 8% hydrochloric acid with a mass concentration of 8% hydrochloric acid in a ratio of 1:3 in mass to volume ratio g / mL, shaking and mixing in a water bath at 80° C. for 3 hours, suction filtration, and filter cake Wash with deionized water until the pH value of the filtrate is 7, dry, pulverize, and pass through a 200-mesh sieve to obtain activated clay; (2) Take activated clay and deionized water in a mass ratio of 1:3 under magnetic stirring at 80°C Mix to make a suspension, add 3% cetyltrimethylamine by mass of activated clay, mix evenly, then add a certain amount of NaOH solution with a mass concentration of 1% to adjust the pH of the system to 11, and stir for 3 hours , suction filtration, the filter cake was washed with 95% ethanol, dried, pulverize...

Abstract

The invention belongs to the technical field of grease refining, specifically provides a decoloring method of pharmaceutical raw material grade camellia seed oil. The method comprises the following steps: adding crude camellia seed oil after degumming and alkali refining in a decoloring tower, heating and warming to a certain temperature, adding self-made mixed decoloring agent, performing vacuum decoloring and drying, sufficiently decoloring and drying under a certain rotating speed, cooling to less than 50 DEG C, filtering, centrifuging and separating the filtrate to obtain the decolored grease. The decoloring method disclosed by the invention utilizes a feature that the modified activated clay is strong in capacity of absorbing the pigment in the oil, and utilizes the feature that the carbonized soybean hull ash has strong absorption capacity to the residual phospholipid, peroxide and free fatty acid; the decoloring speed is fast and the decoloring effect is good.

Description

technical field [0001] The invention belongs to the technical field of oil refining, in particular to a method for decolorizing medicinal raw material grade Camellia oleifera seed oil. Background technique [0002] Camellia oleifera seed oil is commonly known as camellia oil, also known as camellia oil and camellia seed oil. It is a pure natural high-grade edible vegetable oil extracted from the mature seeds of common camellia oleifera (Camellia oleifera Abel) in the family Theaceae. It is golden or light yellow in color and pure in quality. It is clear and transparent, with a delicate smell and a pure taste. Camellia oil is an excellent curative health-care nutritional oil, with an unsaturated fatty acid content as high as 85-97%, which is the crown of various edible oils. Camellia oil has good stability and anti-oxidation properties, long shelf life, high temperature resistance, easy digestion and absorption. Camellia oil contains specific physiologically active substanc...
