Embodiment 1

[0024] Clean the papaya seeds (conventional water washing), dry (dry at 60°C until the water content is ≤5%), and crush until passing through a 40-mesh sieve; weigh 50 g of the crushed papaya seed powder, add 500 mL of petroleum ether, and stir and mix; Then insert the ultrasonic-emitting probe directly into the feed liquid, and extract for 45s under the condition of power of 360W; after the extraction is completed, filter with suction to remove the dregs to obtain the extract; evaporate the collected extract at low temperature, and recover the solvent at the same time; finally The papaya seed oil from which the solvent was removed was vacuum-dried (until the moisture content≤5%) to obtain 16.45 g of the papaya seed oil, with a yield of 32.9%.

Embodiment 2

[0026] Clean the papaya seeds, dry them, and crush them until they pass through a 40-mesh sieve; weigh 50g of crushed papaya seeds powder, add 250mL of petroleum ether, and stir to mix; then insert the probe that emits ultrasonic waves directly into the feed liquid. Extract under the same conditions for 30s; after the extraction, filter with suction to remove the residue to obtain the extract; evaporate the collected extract at low temperature, and recover the solvent at the same time; finally vacuum-dry the papaya seed oil from which the solvent has been removed to obtain 12.80 g of papaya seed oil , and its yield was 25.6%.

Embodiment 3

[0028] Clean the papaya seeds, dry them, and crush them to pass through a 40-mesh sieve; weigh 50g of the crushed papaya seeds powder, add 750mL of petroleum ether, and stir to mix; then insert the ultrasonic probe directly into the feed liquid, at a power of 480W Extract under the same conditions for 60s; after the extraction, filter with suction to remove the dregs to obtain the extract; evaporate the collected extract at low temperature, and recover the solvent at the same time; finally vacuum-dry the papaya seed oil from which the solvent has been removed to obtain 14.90 g of papaya seed oil , and its yield was 29.8%.

[0029] Experiment 1, the papaya seed oil that above-mentioned 3 embodiments are gained carries out the analysis of composition with GC-MS method, and the relative content (according to area normalization method) of main fatty acid is as follows table 1:

[0030] Table 1. Relative content of main fatty acids

Abstract

The invention discloses a method for quickly extracting papaya seed oil, comprising the steps of washing papaya seeds, drying at low temperature until water content is < / =5%, crushing the dried papaya seeds, and screening with a 40-mesh screen; adding an extracting agent to the screened papaya seed powder, and stirring and mixing; inserting an ultrasonic transmitting probe directly into extracting solution with the papaya seed powder, and ultrasonically crushing and extracting for 10-90 s; after extracting, performing suction filtering, and removing residue to obtain extract; evaporating the collected extract to recycle a solvent, and performing vacuum drying to obtain the papaya seed oil. The papaya seed oil is extracted by ultrasonic crushing in the invention, the ultrasonic transmitting probe is inserted directly into the solvent with papaya seed powder, the papaya seed powder is subjected directly to ultrasonic action, papaya seed oil in the papaya seed powder is accelerated to quickly dissolve in the solvent, the technical cycle is significantly shortened, extracting efficiency is improved, the cost is lowered, and the method is highly worthy of popularization and application.

Description

technical field [0001] The invention belongs to the field of extraction of effective plant components, and relates to a method for extracting papaya seed oil from papaya seeds. Background technique [0002] Papaya is known as the "King of Baiyi Fruits". It is a plant of the genus Papaya in the Rosaceae family, which integrates ornamental, edible and medicinal uses. Papaya is rich in more than 17 kinds of amino acids and a variety of nutritional elements. Regular consumption has the health effects of calming the liver and stomach, relaxing muscles and activating collaterals, softening blood vessels, and enhancing physical fitness. At present, the utilization of papaya fruits in China is mainly concentrated in fresh fruit and pulp processing, and there are few reports on the research and development of papaya seed oil, its by-product. Due to the scattered and small-scale planting of papaya resources, the development of its industrial chain has not been valued. During process...
