Embodiment 1

[0017] Embodiment 1: prepare seabuckthorn fruit oil from seabuckthorn pulp, and its preparation steps are as follows:

[0018] 1) Ask for 100kg of fresh seabuckthorn fruit pulp obtained by pressing, and measure the oil content of seabuckthorn fruit 2.98kg according to the method of "GB / T 14488.1-2008 Determination of Oil Content in Vegetable Oils" and using a conventional reflux extractor;

[0019] 2) Enzymatic hydrolysis treatment of the seabuckthorn pulp obtained in the above step: using compound pectinase and cellulase to process the seabuckthorn pulp. Be pectinase by mass ratio: compound compound enzyme in the ratio of cellulase=3: 2.0, 120g pectinase is mixed with 80g cellulase, make 200g compound enzyme (wherein pectinase and cellulase are respectively It is the product of Novozymes (China) Biotechnology Co., Ltd., wherein the activity of pectinase is 200000IU / g, and the activity of cellulase is 2000IU / g.; 100kg of seabuckthorn pulp obtained in step 1) is placed in the e...

Embodiment 2～ Embodiment 4

[0022] Embodiment 2~Example 4: Sea-buckthorn fruit oil is produced from fresh sea-buckthorn fruit pulp 100kg, and its preparation step is identical with embodiment 1, and its process condition and its oil yield value are shown in Table 1, other technological operations and The description is the same as in Example 1.

[0023] Embodiment 5~Example 7 are comparative examples, prepare seabuckthorn fruit oil from fresh seabuckthorn fruit pulp, the fresh sea buckthorn fruit pulp raw materials that get are respectively identical with embodiment 1~embodiment 3, and its preparation steps are the same as those in the implementation Same as Example 1, but only use pectinase alone to treat seabuckthorn pulp, its process conditions are respectively the same as those of Examples 1 to 3, its process conditions and oil yield values ​​are shown in Table 1, and other process operations and descriptions are the same as Example 1 is the same.

[0024] Table 1 (the raw material of each embodimen...

Abstract

The invention discloses a method for preparing sea buckthorn berry oil from sea-buckthorn pulp, comprising the following steps of: adding complex enzyme into sea-buckthorn pulp at the reaction temperature of 50-55DEG C, the rotating speed for stirring of 150-160r/min and the reaction time for 4-4h, wherein the mass ratio of pectinase to cellulose in the complex enzyme is 3:2-3 and the addition of the enzyme is 2.0-3.0g/1kg of the sea-buckthorn pulp; adding hot water with the temperature of 60-65DEG C into a sea-buckthorn pulp enzymolysis liquid obtained by enzyme treatment, wherein the volume ratio of the water adding amount to the enzymolysis liquid is 0.5:0.5-1; maintaining the water treatment temperature at 60-65DEG C, the rotating speed for stirring at 150-160r/min and the reaction time for 2-3h; freezing, centrifuging and separating the enzymolysis liquid subjected to water treatment at the rotating speed for stirring of 8,000-8,500r/min, the temperature of 5-10DEG C and the time for 20-25min; and obtaining an upper layer of light-phase substance of sea buckthorn berry oil after centrifuging with the oil yield up to about 97 percent.

Description

Technical field: [0001] The invention relates to a method for preparing seabuckthorn fruit oil, in particular to a method for extracting seabuckthorn fruit oil from seabuckthorn pulp. Background technique: [0002] Sea buckthorn fruit (Hippophae rhamnoides L.) is also known as vinegar willow, sour buckthorn and so on. Sea buckthorn fruit contains a variety of vitamins, rich in protein, amino acids, organic acids, sterols and trace elements. It is a nutritious wild fruit with high medicinal value. The seeds, pulp and peel of seabuckthorn fruit contain oily ingredients. [0003] Seabuckthorn fruit oil is rich in vitamin E, carotene, unsaturated fatty acids, phytosterols and free amino acids, etc. It has the effects of lowering blood cholesterol, anti-aging and enhancing immunity. Widely used in health products, food and cosmetics. [0004] In the prior art, solvent extraction and supercritical extraction. Solvent extraction method, such as Chinese patent CN91104383.7, has ...
