Problems solved by technology

However, because the free fatty acid content of crabapple seed crude oil is high in acid value, which can reach more than 15%, and the oil contains non-triglyceride components and xanthones (Xanthones) and coumarins that are not contained in other oil plants. (Coumarins), flavonoids (Flavonoids), terpenoids (Terpenoids) and other types of compound components, these substances have certain toxicity; in addition, non-triglyceride components also include pigments, bitter substances, volatile odor substances, etc. Make the prepared crude oil dark green and have a special smell similar to Chinese herbal medicine, and the crude oil also has a bitter taste
Therefore, tamanu seeds have been used as external medicine such as crude oil for its antibacterial effect, and have not been developed and utilized as edible oil.

Embodiment 1

[0059] (1) Weigh the crabapple seed crude oil and heat it to 70°C, first add phosphoric acid with a mass concentration of 85% according to 0.1% of the mass of the crabapple seed crude oil, stir at a speed of 10r / min for 25min, and then Add 4% of the oil quality into hot water at a temperature of 90°C, continue stirring at the same rotational speed for 30 minutes, leave to settle for 2 hours after stirring, remove the precipitate, and obtain degummed crude oil;

[0060] (2) At 40°C, according to the ratio of degummed crude oil:methanol (mass:volume) = 1:2.5, add methanol to the degummed crude oil and stir rapidly at a speed of 200r / min for 25min, and then separate after standing for 2h The lower oil phase was taken out, and then the step of adding methanol to the lower oil phase and standing for stratification was repeated 3 times, and the lower oil phase obtained by the last separation was rotary-evaporated at 70° C. to remove methanol, and the extracted crude oil was obtained;...

Embodiment 2

[0066] (1) Heat the crabapple seed crude oil to 60°C after weighing, first add phosphoric acid with a mass concentration of 90% according to 0.05% of the mass of crabapple seed crude oil, stir at a speed of 5r / min for 30min, and then Add 2% of the oil mass into hot water at a temperature of 95°C, continue stirring at the same speed for 20 minutes, leave to settle for 3 hours after stirring, remove the precipitate, and obtain degummed crude oil;

[0067] (2) At 45°C, according to the ratio of degummed crude oil: methanol (mass: volume) = 1:2, methanol was added to the degummed crude oil and stirred rapidly at a speed of 150r / min for 15min, and then separated after standing for 3h The lower oil phase was taken out, and then the step of adding methanol to the lower oil phase and standing for stratification was repeated 3 times, and the lower oil phase obtained by the last separation was rotary-evaporated at 80° C. to remove methanol, and the extracted crude oil was obtained;

Abstract

The invention discloses a refining method of crabapple seed crude oil, and the method comprises the following steps: heating the crabapple seed crude oil to 60-80 DEG C, adding phosphoric acid, stirring, adding hot water, stirring, and removing a precipitate to obtain degummed crude oil; adding methanol into the degummed crude oil at 35-45 DEG C, stirring, separating out a lower-layer oil phase, and then removing the methanol to obtain extracted crude oil; adding a NaOH solution into the extracted crude oil, quickly stirring at 50-70 DEG C and then slowly stirring to obtain a mixed solution; heating an upper-layer oil phase which is separated from the mixed solution to 70-90 DEG C, adding hot water, stirring, and removing solid substances to obtain deacidified, decolorized and debittered crude oil; heating the deacidified, decolorized and debittered crude oil to 220-240 DEG C, and stirring under the conditions of introducing water vapor and vacuumizing to obtain deodorized crude oil; and heating the deodorized crude oil to 70-80 DEG C, cooling to 17-23 DEG C, keeping the temperature, growing crystals, and removing the crystals to obtain refined crabapple seed oil. The invention provides a method for preparing edible oil meeting national standard requirements by refining the crabapple seed crude oil.

Description

technical field [0001] The invention relates to the technical field of edible oil, in particular to the technical field of edible oil refining, in particular to a refining method of crabapple seed crude oil. Background technique [0002] At present, the raw materials of edible oil are mainly soybean, rapeseed, peanut and so on. Edible oil is obtained by pressing and solvent leaching the above-mentioned oil to obtain crude fat, commonly known as crude oil, and then refining the crude oil. The main component of crude oil is triglyceride, and it also contains non-triglyceride components. Non-triglyceride components include suspended impurities, water, peptizing substances and oil-soluble substances. Non-triglyceride components are also known as impurities. The non-triglyceride components in crude oil will affect the safety and stability of edible oil. Therefore, crude oil needs to be refined to remove these impurities before it can be used as edible oil. [0003] The genera...
