Problems solved by technology

Except for solvent extraction, other methods all have the disadvantage of low oil yield. For example, the extraction rate of supercritical fluid extraction is 18%-22%, and the oil yield of pectinase method is 68%-72%. The oil efficiency is as high as 85%-90%, but there are disadvantages such as high cost, potential safety hazards, and some organic solvents remaining in the oil, which have a certain impact on the quality of the oil.

Embodiment 1

[0024] The preparation method of seabuckthorn fruit oil, concrete steps are as follows:

[0025] (1) Seabuckthorn fruit cleaning: put the seabuckthorn fruit in a washing machine, use 12°C-15°C drinking water that meets the national standard for drinking water to wash the seabuckthorn fruit, and drain the water for later use;

[0026] (2) Quick-freezing: spread the drained sea-buckthorn fruit in the quick-freezing tank. The thickness of each quick-freezing tank is 16cm-20cm. The quick-freezing tank is cooled by liquid ammonia, and the quick-freezing temperature is adjusted from -25°C to -28°C. ℃, quick freezing time 9 minutes -12 minutes;

[0027] (3) Beating: put the quick-frozen seabuckthorn fruit in a beater, beat for 3-5 minutes, filter and take the seabuckthorn pulp;

[0028] (4) Pectinase hydrolysis: use pectinase produced by Novozymes Biotechnology Co., Ltd. with an enzyme activity of 200,000 IU / g to hydrolyze seabuckthorn pulp. The hydrolysis temperature is 55°C-60°C. ...

Abstract

The invention provides a sea buckthorn berry oil preparation method which is implemented by the following steps: (1) cleaning sea buckthorn berries; (2) quickly freezing; (3) pulping; (4) hydrolyzing pectinase; (5) precipitating with alcohol; (6) freezing to stratify sea buckthorn berry oil; (7) extracting raw oil; (8) recovering ethanol by distillation; (9) carrying out secondary freezing and thawing to separate the sea buckthorn berry oil; and (10) refining to obtain the sea buckthorn berry oil. In the invention, poisonous and odorous organic solvents are not used, and the extraction process cost is low, thereby ensuring that the preparation method has a high use value.

Description

(1) Technical field [0001] The invention relates to a preparation method of seabuckthorn fruit oil, in particular to a method for secondarily freezing and thawing seabuckthorn fruit pulp at low temperature and separating seabuckthorn fruit oil, belonging to the field of food processing. (2) Background technology [0002] Seabuckthorn is a rare herbal medicine that can grow under harsh conditions and contains a variety of active ingredients. It is a common Chinese medicine used by Tibetan and Mongolian doctors in ancient my country to treat diseases. Pharmacological efficacy of promoting blood circulation and dispelling diseases. Every 100 grams of pulp contains 78 grams of water, 0.9 grams of protein, 2.3 grams of fat, 0.6 grams of crude fiber, 17.7 grams of carbohydrates, 0.5 grams of ash, 20 mg of carotene, 0.08 mg of thiamine, 0.1 mg of riboflavin, niacin 0.2 mg, 160 mg of ascorbic acid, 5.82 mg of vitamin E, etc. Sea buckthorn fruit oil is a substance extracted from sea...
