Problems solved by technology

Compared with other extraction methods, the pressing method has high energy consumption and low oil yield; although the solvent extraction method has a high oil yield, there are solvent residues, which cannot be completely removed in theory; and supercritical CO 2 It has high requirements for equipment and high cost, which is not conducive to the development of industrialization
The method has mild conditions, simple operation, low equipment requirements, no pollution, no residue, and the obtained peony seed oil has no impurities and good quality. This process for extracting peony seed oil has not been reported

Embodiment 1

[0025] Crush the raw materials and pass through a 40-mesh sieve. Take 50g of seed powder, add 250ml of water, and mix to form a slurry for later use. Use 1mol / L hydrochloric acid to adjust the pH of the slurry to 4.5, add 15mL of cellulose-pectin complex enzyme (Danish Novozymes complex cellulase Celluclast 1.5L: polygalacturonase (pectinase) Pectinex Ultra SP-L Mixed at 2:1, enzyme activity 1.2*10 5 U / g), stirring and extracting at 50°C for 2 hours to obtain enzymolysis solution A, adjust the pH of enzymolysis solution A to 7 with 1mol / L sodium hydroxide, add 6mL α-medium temperature amylase (Danish Novozymes medium temperature amylase BAN 480, enzyme Live 4*10 4 U / g), stirring and extracting at 70°C for 0.5h to obtain enzymolysis solution B, adjust the pH of enzymolysis solution B to 8.5 with 1mol / L sodium hydroxide, add 1g alkaline protease (Novozyme Alcalase 2.4L, enzyme Live 2.5*10 5 U / g), stirring and extracting at 60°C for 2 hours to obtain the final enzymolysis s...

Embodiment 2

[0034] Crush the raw materials and pass through a 40-mesh sieve. Take 1000g of seed powder, add 4L of water, and mix to form a slurry for later use. Use 1mol / L hydrochloric acid to adjust the pH of the slurry to 4.5, add 30g of cellulose-pectin complex enzyme (commercially available domestic cellulase: pectinase in 1:1, enzyme activity 5*10 4 U / g), stirring and extracting at 50°C for 2.5h to obtain enzymolysis solution A, adjust the pH of enzymolysis solution A to 7 with 1mol / L sodium hydroxide, add 20g α-medium temperature amylase (commercially available domestic α-medium temperature amylase, enzyme Live 1*10 4 U / g), stirring and extracting at 70°C for 1 hour to obtain enzymolysis solution B, adjust the pH of enzymolysis solution B to 8.5 with 1mol / L sodium hydroxide, add 50g alkaline protease (commercially available domestic alkaline protease, enzyme activity 1 *10 5 U / g), stirring and extracting at 60°C for 2 hours to obtain the final enzymolysis solution. Centrifuge ...

Embodiment 3

[0039] Crush the raw materials and pass through a 40-mesh sieve. Take 500g of seed powder, add 2.5L of water, and mix to form a slurry for later use. Use 1mol / L hydrochloric acid to adjust the pH of the slurry to 4.5, add 45g of cellulose-pectin compound enzyme (commercially available domestic cellulase: pectinase is compounded at 1:1, and the enzyme activity is 2*10 4 U / g), stirring and extracting at 50°C for 2.5 hours to obtain enzymolysis solution A, adjust the pH of enzymolysis solution A to 7 with 1mol / L sodium hydroxide, add 8g of α-medium-temperature amylase (commercially available domestic α-medium-temperature amylase, enzyme Live 1*10 4 U / g), stirring and extracting at 70°C for 1 hour to obtain enzymolysis solution B, adjust the pH of enzymolysis solution B to 8.5 with 1mol / L sodium hydroxide, add 35g alkaline protease (commercially available domestic alkaline protease, enzyme activity 5 *10 4 U / g), stirring and extracting at 60°C for 2 hours to obtain the final ...

Abstract

The invention discloses a method for extracting oil from peony seeds or peony seed dregs. The method comprises the following steps: (1) pretreatment; (2) enzymolysis; (3) centrifuging; (4) demulsification; (5) dreg washing. Free oil, an emulsion layer, protein hydrolysate and dregs are obtained after enzymatic hydrolysate is centrifuged, wherein the free oil is peony seed oil, and a certain amount of oil can also be recovered after the emulsion layer and the dregs are subjected to demulsification and dreg washing respectively. According to the method, the peony seed oil can be extracted without drying raw materials, the operation is simple, the requirement for equipment is low, the oil yield is high, the oil quality is good, solvent residues and environmental pollution are avoided, and the obtained protein hydrolysate and dregs can also be further used comprehensively.

Description

technical field [0001] The invention relates to a method for extracting edible peony seed oil from peony seeds or peony meal, and belongs to the field of deep processing of agricultural products. Background technique [0002] Peony is a shrub of Paeoniaceae of Ranunculaceae, which is widely planted in various parts of my country. The annual output of peony seeds is tens of thousands of tons. It is rich in resources and has great potential for development. In recent years, the development and utilization of peony seeds have received widespread attention. Numerous studies have shown that peony seeds have high nutritional value, with an oil content of about 29-34% and a protein content of about 18-22%. On March 22, 2011, peony seeds were approved by the Ministry of Health as a new resource food "Announcement of the Ministry of Health on Approving Ingot Maple Seed Oil and Peony Seed Oil as New Resource Foods" (2011 No. 9). [0003] The total content of unsaturated fatty acids i...
