Embodiment 1

[0019] After the dried jasmine fruit is crushed, after passing through a 16-mesh sieve, the jasmine fruit powder and deionized water are mixed in a mass ratio of 1:6, and pectinase with 1.8% of the mass of the jasmine fruit powder is added. Buffer solution, adjust pH=5.0, enzymatically hydrolyze in 50°C water bath for 2h. The enzymolysis solution is centrifuged directly, the centrifuge speed is 4000r / min, and the centrifugation time is 10min, and the free oil, emulsion, hydrolyzate and slag are separated, and the emulsion is centrifuged again to obtain free oil, and the obtained free oil is combined. By utilizing the Soxhlet extraction method (GB5009.6-85) to carry out the determination of the total oil content in the sample, using the formula, free oil yield (%)=total free oil / raw material total oil x 100% to calculate the free oil The yield was 65.8%.

Embodiment 2

[0021] After the dried water gardenia is crushed, after passing through a 16 mesh sieve, the gardenia fruit powder and deionized water are mixed with a mass ratio of 1:5, and pectinase with 2.4% of the quality of the gardenia fruit powder is added, and the enzymatic hydrolysis uses an acidic Buffer solution, adjusted to pH=5.3, enzymatically hydrolyzed in a water bath at 45°C for 4 hours. The enzymolysis solution is directly centrifuged, the centrifuge speed is 4000r / min, and the centrifugation time is 15min, the free oil, emulsion, hydrolyzate and slag are separated, the emulsion is centrifuged again to obtain free oil, and the obtained free oil is combined to obtain The rate is 66.0%.

Embodiment 3

[0023] After the dried jasmine fruit powder is pulverized, after passing through a 16-mesh sieve, the jasmine fruit powder and deionized water are mixed in a mass ratio of 1:8, and a combined enzyme with 3.5% of the quality of the jasmine fruit powder is added, wherein pectinase and The mass ratio of cellulase is 7:20, acid buffer solution is used for enzymolysis, pH=5.0 is adjusted, and enzymolysis is performed in a water bath at 45° C. for 3 hours. After adding 1 volume of petroleum ether to the centrifuge for extraction, the solvent was recovered under reduced pressure to obtain gardenia free oil, and the free oil yield was 88.3%.

Abstract

The invention relates to a method for aqueous enzymatic extraction of gardenia oil. The method adopts gardenia fruits as raw materials, which are subjected to crushing, enzymolysis and centrifugation, thus obtaining the gardenia oil. The gardenia oil prepared by the invention has high yield and high quality, is easy to refine, and maintains the natural nutrients and function of gardenia oil. Compared with the traditional squeezing method and organic solvent extraction method, the method has the advantages of simple production equipment, safe operation, less pollution, and low energy consumption, etc.

Description

technical field [0001] The invention relates to a method for extracting gardenia oil by an aqueous enzymatic method, and belongs to the technical field of oil extraction by an aqueous enzymatic method. Background technique [0002] Gardenia is the fruit of Gardenia jasminoides Ellis, a Rubiaceae plant. It is abundant in the mountainous areas of Jiangsu, Zhejiang, Fujian, Jiangxi, Hui, Hunan and other provinces. plant resources. Common cultivars and varieties are Shanzhizi, Huangzhizi and Water Gardenia. It has been recorded in detail in Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty: Gardenia has the functions of protecting the liver, promoting gallbladder, lowering blood pressure, calming, hemostasis, and reducing swelling; Blood pressure, diabetes etc. [0003] The oil content in gardenia fruit is similar to that of oil crop soybean. The fatty acids contained are mainly palmitic acid and linoleic acid, accounting for 91.4% of the fatty acid content. Th...
