Embodiment 1

[0018] A preparation method of hazelnut oil is prepared by the following steps:

[0019] 1) Dry 100kg of peeled hazelnut kernels until the water content is 9%, put the dried hazelnut kernels into an airtight container, and store them away from light for 5 days;

[0020] 2) Crush the hazelnut kernels that have been stored away from light into 30 meshes to obtain hazelnut powder;

[0021] 3) Divide the hazelnut powder into two parts on average, one part of the hazelnut powder is rotated and roasted at 110°C for 20 minutes, and the roasted material is sent to an oil press for pressing to obtain a crude oil and a hazelnut meal;

[0022] 4) Press another portion of hazelnut powder directly in the oil press to obtain secondary crude oil and secondary hazelnut meal;

[0023] 5) Crush the primary hazelnut meal and the secondary hazelnut meal to 50 mesh, rotate and bake at 130°C for 30 minutes, and send the baked material to an oil press for pressing to obtain tertiary crude oil and t...

Embodiment 2

[0027] A preparation method of hazelnut oil is prepared by the following steps:

[0028] 1) Dry 100kg of peeled hazelnut kernels until the water content is 10%, put the dried hazelnut kernels into an airtight container, and store them in the dark for 4 days;

[0029] 2) Crush the hazelnut kernels that have been stored away from light into 35 meshes to obtain hazelnut powder;

[0030] 3) Divide the hazelnut powder into two parts on average, one part of the hazelnut powder is rotated and roasted at 105°C for 20 minutes, and the roasted material is sent to an oil press for pressing to obtain a crude oil and a hazelnut meal;

[0031] 4) Press another portion of hazelnut powder directly in the oil press to obtain secondary crude oil and secondary hazelnut meal;

[0032] 5) Crush the primary hazelnut meal and the secondary hazelnut meal to 60 mesh, and rotate and bake at 125°C for 35 minutes. The baked material is sent to an oil press for pressing to obtain tertiary crude oil and t...

Embodiment 3

[0036] A preparation method of hazelnut oil is prepared by the following steps:

[0037] 1) Dry 100kg of peeled hazelnut kernels until the water content is 11%, put the dried hazelnut kernels into an airtight container, and store them in the dark for 3 days;

[0038] 2) Crush the hazelnut kernels that have been stored away from light into 40 meshes to obtain hazelnut powder;

[0039] 3) Divide the hazelnut powder into two parts evenly, one part of the hazelnut powder is rotated and roasted at 100°C for 20 minutes, and the roasted material is sent to an oil press for pressing to obtain a crude oil and a hazelnut meal;

[0040] 4) Press another portion of hazelnut powder directly in the oil press to obtain secondary crude oil and secondary hazelnut meal;

[0041] 5) Crush the primary hazelnut meal and the secondary hazelnut meal to 70 mesh, rotate and bake at 120°C for 30 minutes, and send the baked material to an oil press for pressing to obtain tertiary crude oil and tertiary...

Abstract

The invention discloses a preparation method of hazelnut oil. The hazelnut oil is prepared according to steps as follows: hulled hazelnut kernels are dried, stored in an airtight container in a dark place and then ground, and hazelnut powder is obtained; the hazelnut powder is equally divided into two parts, one part of the hazelnut powder is subjected to hot squeezing, the other part of the hazelnut powder is subjected to cold squeezing, hazelnut meal obtained after hot squeezing and hazelnut meal objected after cold squeezing are mixed, ground and subjected to hot squeezing, crude oil obtained after three times of squeezing is mixed, filtered by a membrane and cooled, and the hazelnut oil can be prepared. The hazelnut kernels are dried, stored in the airtight container in a dark place and squeezed multiple times, and the oil yield of peony seeds can be effectively increased and can be as high as 52.1%; with the adoption of the oil squeezing manner combining cold squeezing and hot squeezing, the nutrition of the hazelnut oil is guaranteed, strong and pure fragrance of the hazelnut oil is guaranteed, and the product quality is high; loss of the fragrance and nutritional ingredients of the peony seed oil are reduced through membrane filtration; according to the method, no organic solvents are required, no residues are left, and the method is simple, easy to implement and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of edible oil, in particular to a preparation method of hazelnut oil. Background technique [0002] Hazelnut, belonging to the Betaceae Corylus plant, also known as mountain chestnut, pointed grain, hammer and so on. There are about 20 species of Corylus in the world, distributed in Asia, Europe and North America; in China, there are 8 species and 2 varieties, distributed in Northeast, East, North, Northwest and Southwest regions. Hazelnut is an excellent tree species with both fruit and material. Its fruit is shaped like a chestnut, with a hard shell, fat white and round kernel, aroma, and high oil content. It tastes particularly delicious and has a lingering aftertaste. It has the title of "King of Nuts". [0003] Hazelnut itself is rich in oil, most of which are unsaturated fatty acids, and its content reaches 60.5%, which makes the fat-soluble vitamins contained in it more easily absorbed by the human body, and ...
