[0029] Example 1 Supercritical CO of pine nut oil 2 Extraction preparation method implementation 1

[0030] Whole pine nuts are used as raw materials, and the oil residue after oil extraction will be used to process soft-packed instant pine nuts, so the extraction process is required to cause little damage to the appearance of pine nuts, just extract part of the oil and keep it in the raffinate of fat is used to enhance the flavor of ready-to-eat pine nuts.

[0031]Turn on the main power supply; start the refrigeration device, start the heating device of the extraction kettle and the separation kettle, the extraction kettle adopts 45°C, the separation I adopts 8MPa, 40°C; the separation II adopts 5MPa, 35°C. Whole pine nuts shelled from pine nuts are used as raw materials, anti-oxidant raw material ginger powder is added to the raw material of pine nuts, the addition amount is 1% of the weight of the pine nuts, and the addition amount of the synergist citric acid is 0.05% of ...

[0033] Example 2 Supercritical CO of pine nut oil 2 Extraction preparation method implementation 2

[0034] One-half to one-quarter crushed and mixed pine nuts are used as raw materials, and the oil residue after oil extraction will be used to process soft-packed instant pine nuts. Therefore, it is required that the extraction process has little damage to the appearance of pine nuts, and part of the oil is extracted. Yes, the oil that remains in the raffinate is used to enhance the flavor of the ready-to-eat pine nuts.

[0035] Turn on the main power supply; start the refrigeration device, start the heating device of the extraction kettle and the separation kettle, the extraction kettle adopts 48°C, the separation I adopts 8MPa, 42°C; the separation II adopts 5MPa, 33°C. With 1 / 2 broken pine nuts after shelling of pine nuts as raw material, the antioxidant raw material ginger powder is added to the raw material of pine nuts, the addition amount is 1.2% of the weight of the pi...

[0037] Example 3 Supercritical CO of pine nut oil 2 Extraction preparation method implementation 3

[0038] A quarter of broken pine nuts are used as raw materials, and the oil residue after oil extraction will be used to process soft-packed instant pine nuts. Therefore, it is required that the extraction process has little damage to the appearance of pine nuts, and only part of the oil can be extracted and retained in the raffinate The oil in the pine nuts is used to enhance the flavor of instant pine nuts.

[0039] Turn on the main power supply; start the refrigeration device, start the heating device of the extraction kettle and the separation kettle, the extraction kettle adopts 40°C, the separation I adopts 10MPa, 45°C; the separation II adopts 6MPa, 30°C. Use 1 / 4 broken pine nuts after shelling of pine nuts as raw material, add anti-oxidant raw material ginger powder to pine nuts raw material, the addition amount is 2.5% of the weight of pine nuts, and the addition amou...

Abstract

Extraction of pine nut oil, residual oil dregs food after extraction as well as its producing method, that is obtaining pine nut after exuviating and removing skin; obtaining pine nut oil by exceed critical CO2 hydro-extraction; to get out the residual oil dregs after extraction to dry, then to grind into powder, and adding Chinese chestnut powder and walnut powder to mix as well as dry again to produce complex pine nut nutrition powder. Or using the pine nut as whole body, one-half crash, quarter crash to extract residual oil dregs, then to add into a flovoring liquid composed of common salt, liquorice, aniseed, pepertree, Chinese cinnamon, fine ginger and water to bloat, then produce dainty instant pine nut. Compared with the existing technology, the present invention improves the oil-displaced ratio, and produces dainty instant pine nut foods using extracting residual dregs, improves the using ratio of the pine nut; the line exceed critical CO2 hydro-extracting technics which takes raw ginger as anti-oxidant, ethanol as entrainer, is more advanced.

Description

technical field [0001] The present invention relates to a kind of supercritical CO of pine nut oil 2 Extraction method and comprehensive utilization of raffinate after oil extraction. Background technique [0002] Pine nuts are a traditional health-care product, and eating pine nut kernels can prolong life. According to measurements, every 100g of pine nuts contains 13.51-19.88g of crude protein, 51.72-69.13g of crude fat, 8.11-13.44g of total sugar, and 2.60-4.14g of crude fiber; the protein of pine nuts is composed of 18 kinds of amino acids, In particular, the content of various essential amino acids is quite rich. Crude fat contains 13 kinds of fatty acids, of which linoleic acid accounts for 35.77%-43.13%, linolenic acid accounts for 18.61%-37.93%, oleic acid accounts for 12.49%-27.17%, and the total amount of unsaturated fatty acid exceeds 60%. Calcium, phosphorus, manganese, cobalt, copper, zinc, iron and other trace elements. Pine nuts are not only a delicious fo...
