Problems solved by technology

However, due to the high oil content of pine nuts and the fine and soft texture, it is difficult to obtain pine nut oil by traditional pressing methods
In the traditional pressing method, the pine nut kernels are directly added to the oil press for pressing, and the emulsion-like mixture formed due to the high oil content of the pine nut and the fine and soft texture will flow out of the oil press directly, and it is impossible to achieve oil and meal separation
Therefore, someone solves the problem that the texture of pine nuts is too soft by adding a certain proportion of pine nut shells to the pine nuts. However, due to the oily pine oil contained in the pine nut shells, it will bring heavy pine oil to the pressed pine nut oil. Taste, affect the edible quality of pine nut oil, not easy to

Embodiment 1

[0012] Weigh 95 kg of pine nut kernels, weigh 5 kg of screened and cleaned straw or wheat straw, rice husk, etc., mix them well according to the proportion, then put them into a wok and heat them to 50°C, and put the heated mixture into Press the oil in the oil press. The meal that has been squeezed for the first time still contains a certain amount of pine nut oil. According to the content, it can be squeezed 2 to 4 times until no more oil is produced from the meal. The pressed pine nut oil is naturally settled at 45.0°C for 4 days, which can effectively separate the oil from the residue, and transfer the supernatant oil to obtain light yellow and clear pine nut oil with the unique aroma of pine nuts .

Embodiment 2

[0014] Weigh 90 kg of pine nut kernels, weigh 10 kg of screened and cleaned straw or wheat straw, rice husk, etc., mix them well in proportion, then put them into a wok and heat them to 60.0°C, and put the heated mixture into Press the oil in the oil press. The meal that has been squeezed for the first time still contains a certain amount of pine nut oil. Depending on the content, it can be squeezed 1 to 4 times until no more oil is produced from the meal. The pressed pine nut oil is naturally settled at 40°C for 6 days, which can effectively separate the oil from the residue, and transfer the supernatant oil to obtain light yellow and clear pine nut oil with the unique aroma of pine nuts .

Embodiment 3

[0016] Weigh 85 kg of pine nut kernels, weigh 15 kg of screened and cleaned straw or wheat straw, rice husk, etc., mix them well in proportion, then put them into a wok and heat them to 70°C, and put the heated mixture into Press the oil in the oil press. The meal that has been squeezed for the first time still contains a certain amount of pine nut oil, which can be squeezed 2-4 times according to the content rate until no more oil is produced from the meal. The pressed pine nut oil is naturally settled at 35°C for 8 days, which can effectively separate the oil from the residue, and transfer the supernatant oil to obtain light yellow and clear pine nut oil with the unique aroma of pine nuts .

Abstract

This invention relates to a method for extracting pine seed oil from pine seeds without the need for solvent or complex apparatus. The method largely reduces the extraction cost, and does not use solvent, thus can maintain the natural quality of pine seed oil. The method comprises: crushing the husks of pine seeds, taking out the kernels, mixing with screened and cleaned rice hulls, wheat hulls or segments of rice straws and wheat straws at a volume ratio of (70 plus and minus 30) :(20 plus and minus 19), adding into an oil mill, extracting to obtain pine seed oil, and naturally precipitating at 10-50 deg.C for 1-15 days to separate oil and residues. The obtained pine seed oil is yellow, clear and fragrant.

Description

technical field [0001] The invention relates to a new processing method for preparing pine nut oil for food, medicine or daily use by pressing oil in pine nuts. Background technique [0002] With the improvement of people's living standards, people's consumption concept tends to be natural, green and healthy. Therefore, people's demand for natural and healthy edible oil is increasing, and the requirements are getting higher and higher. Not only the intrinsic quality requirements of edible oil It is very high, and there are also requirements for the processing method of edible oil. More and more people tend to eat edible oil obtained by stupid pressing method (traditional pressing method). [0003] Pine nut oil, as a new type of healthy nut edible oil with health care function, is gradually being recognized by people. However, due to the high oil content of pine nuts and the fine and soft texture, it is difficult to obtain pine nut oil by traditional pressing methods. In th...
