Description

A kind of cold-pressing preparation process of Tamanya seed oil

1. Technical field

The invention belongs to the technical field of vegetable oil processing and is suitable for the processing of tamanu seeds. the

2. Background technology

Qiongya crabapple (Calophyllum inophyllum Linn), also known as crabapple fruit, red thick shell, oregano, Pittosporum, gentleman tree, crabapple wood, is a high-yield woody oil plant, mainly distributed in Hainan, Guangdong, Guangxi in my country , Taiwan and other provinces and regions, Southeast Asia, South Asia, Africa and other tropical regions. In our country, Qiongya crabapple fruit is used to treat eye diseases, traumatic bleeding, rheumatic bone pain, bruises and so on. Research tests have shown that tamanu seed oil is rich in active substances such as xanthones, coumarin derivatives, flavonoids, triterpenoids, and begonia fruit acid, which have the functions of promoting tissue regeneration, anti-neuralgia, antibacterial, anti-inflammatory, and anti-inflammatory. Cytotoxin, anti-ulcer, anti-hepatotoxin, anti-rheumatism, anti-aging, anti-tumor, anti-leukemia, anti-HIV, inhibition of HIV21 reverse transcriptase, inhibition of HIV212KT replication and other activities. At present, there are many domestic studies on the active components of tamanu seed oil and their functions, but there are few reports on how to prepare tamanu seed oil rich in active components. The oil content of Tamanu chinensis pulp is very high, wherein the fruit part contains 25-30% oil, and the kernel part contains 48-55% oil. The content of unsaturated fatty acids in tamanu seed oil is very high, accounting for 60-75% of the total fatty acids, of which oleic acid and linoleic acid are very high. the

3. Contents of the invention

The object of the present invention is to provide a method for preparing tamanu seed oil with simple process, low energy consumption, less processing equipment, rich in natural active ingredients in the finished oil, and no solvent residue. The purpose of the present invention can be achieved through the following technical measures:

(1) the collected Tamanya fruit is dried and peeled off;

(2) Peel the tamanthus seeds with a sheller, and separate the kernels and shells;

(3) Select the high-quality Qiong Tay Begonia seed kernels and seed shells, and wash them with tap water to remove impurities adhering to the surface;

(4) Slice the kernels of Tamanya seeds, put them together with the shells in an oven for drying, the drying temperature is 30°C-60°C, and the drying time is 8h-25h;

(5) Mix the dried Tamanu seed kernels with the Tamanu seed shell in a certain ratio, and pulverize with a pulverizer;

(6) The crushed Tamanya seeds kernel seed husk is directly squeezed at normal temperature, and is filtered with a plate-and-frame filter;

(7) Heat the crude oil to 30°C to 50°C, add water slightly higher than the oil temperature, the amount of water added is 1% to 25% of the crude oil, stir rapidly, and centrifuge to remove the colloid;

(8) Vacuum drying the degummed oil to remove water therein to obtain the finished product Tamanuja seed oil. the

The shelling process of the present invention uses a cutter cage shelling machine for shelling, and the separation process adopts a vibrating screen combined with an air separator for separation.

The slicing process of the present invention uses a slicer to slice, so that the slice thickness is controlled between 0.5 mm and 5.0 mm. the

The drying process of the invention refers to drying the tamanu seeds to a moisture content of 0.1% to 5%. the

The pressing process of the present invention uses a static pressure oil press, the pressing pressure is 50-100 MPa, and the pressing time is 1h-5h. the

The vacuum drying process of the present invention is to vacuum dry for 0.5h to 3h under the conditions of a vacuum degree of 70KPa-110KPa and a temperature of 40°C-50°C. the

The present invention has the following characteristics:

(1) Select high-quality Tamanu seeds, wash the shells and remove impurities to ensure good quality of raw materials without pollution and improve the quality of oil extraction. the

(2) Slice and dry the kernels to ensure uniform drying of the kernels, shorten the drying time and improve work efficiency. the

(3) The seed kernel and seed shell are mixed and pressed in a certain proportion, which dredges the passage of oil and improves the oil yield. the

(4) The low-temperature cold-pressing process is adopted, and there is no high temperature intervention in the whole process, which protects the active ingredients in the tamanu seed oil from being damaged by high temperature. the

(5) No reagent is used in the process, which ensures that the active ingredients in the tamanu seed oil are not destroyed or lost, and that no reagent remains in the finished oil. the

(6) The refining process is simple, the finished tamanu seed oil has a unique dark green color, and the oil is clear and transparent. The degumming and dehydration process effectively improves the quality of the oil and prolongs the shelf life of the tamanu seed oil. the

4. Specific implementation

In order to illustrate the present invention in more detail, describe the present invention in detail below with specific embodiment:

Detailed ways:

Tamana fruits are collected, dried and peeled. The peeled tamanu fruit is sent to the cutter cage peeling machine for shelling, and the tamanu seed kernel and the tamanu seed shell are separated by a vibrating screen and a winnowing machine. The peeled and separated tamanu seed kernels and tamanu seed shells are graded, and high-quality tamanu seed kernels and seed shells are selected and washed with tap water to remove impurities adhering to the surface. Slice the selected tamanu seeds with a slicer, and the thickness of the slices is controlled between 0.5 mm and 5.0 mm. Put the sliced kernels and shells into an oven to dry at a drying temperature of 30°C to 60°C and a drying time of 8h to 25h until the moisture content of the tamanu seed kernels is between 0.1% and 5%. The dried tamanu seed kernels are mixed with the tamanu seed shells in a certain ratio, and pulverized by a pulverizer. After being crushed, it is sent to a static pressure oil press for cold pressing at room temperature, with a pressing pressure of 50-100 MPa and a pressing time of 1h-5h. Filter the crude oil with a plate and frame filter, then heat the crude oil to 30°C to 50°C, and add water slightly higher than the oil temperature, the amount of water added is 1% to 25% of the crude oil, stir quickly, and centrifuge , to remove the colloid. The degummed oil is vacuum-dried at a vacuum degree of 70KPa to 110KPa, at a temperature of 40°C to 50°C, and for a drying time of 0.5h to 3h, to remove the water in it, and obtain a clear dark green finished tamanu seed oil. The accompanying drawing is a process flow chart of the cold pressing preparation process.
