Embodiment 1

[0029] (1) Clean raw raw watermelon seeds, dry them with hot air at 40°C until dry, crush them and pass through a 10-mesh sieve, put them in sealed bags and place them in a desiccator for later use.

[0030] (2) Add 1% of the mass of watermelon seed powder compound cellulase and 1 times water to the watermelon seed powder, stir and stand still for 1 hour.

[0031] (3) Add the mixture in step (2) to the extraction kettle of the supercritical carbon dioxide extraction device, adjust the extraction pressure to 20Mpa, the extraction temperature to 45°C, and the time for 0.5 hours to obtain watermelon seed oil.

Embodiment 2

[0033] (1) Clean the raw watermelon seeds, dry them with hot air at 60°C until they are dry, crush them and pass them through a 50-mesh sieve, put them in a sealed bag and put them in a desiccator for later use.

[0034] (2) Add 3% watermelon seed powder compound cellulase and 2 times water to the watermelon seed powder, stir and stand still for 2 hours.

[0035] (3) Add the mixture in step (2) to the extraction kettle of the supercritical carbon dioxide extraction device, adjust the extraction pressure to 20Mpa, the extraction temperature to 45°C, and the time for 0.5 hours to obtain watermelon seed oil.

Embodiment 3

[0037] (1) Clean the raw watermelon seeds, dry them with hot air at 60°C until they are dry, crush them and pass them through a 50-mesh sieve, put them in a sealed bag and put them in a desiccator for later use.

[0038] (2) Add 3% watermelon seed powder compound cellulase and 2 times water to the watermelon seed powder, stir and stand still for 2 hours.

[0039] (3) Add the mixture in step (2) to the extraction kettle of the supercritical carbon dioxide extraction device, adjust the extraction pressure to 30Mpa, the extraction temperature to 50°C for 1 hour, in order to obtain watermelon seed oil.

Abstract

The invention discloses a method for extracting watermelon seed oil. The method comprises the following steps: (1) smashing watermelon seeds to obtain watermelon seed powder; (2) mixing the watermelon seed powder with cellulose and water; and (3) adding a mixture obtained in the step (2) into a supercritical carbon dioxide extracting device for extracting to obtain the watermelon seed oil. The method with the combination of enzymolysis and supercritical carbon dioxide extraction has the advantages of convenience, non-toxicity, low temperature, high extraction rate and the like. The obtained watermelon seed oil has high content of unsaturated fatty acid.

Description

technical field [0001] The invention relates to the field of food processing, and more specifically, the invention relates to a method for extracting watermelon seed oil. Background technique [0002] Watermelon has a long history of cultivation in our country. During the Ming Dynasty, Li Shizhen recorded in "Compendium of Materia Medica": "According to Hu Jiao's melon seeds in Huihe, the name is watermelon. Watermelon has entered China since the Five Dynasties, and it is present in both north and south." Today my country is already the largest watermelon producing area in the world, and it can be cultivated in most parts of the country. Watermelon seeds are the kernels of watermelons, which are edible and medicinal, and consist of shells and kernels. Watermelon seeds can be processed into spiced watermelon seeds, creamy watermelon seeds, multi-flavored watermelon seeds, etc. Watermelon seeds have now become one of the most popular snack foods in my country. [0003] Accord...
