Embodiment 1

[0010] Pulverize, sieve, and dry the turmeric, weigh 1000 g of turmeric powder in the extraction kettle, set the temperature to 50°C, and start heating. When it reaches 50°C, turn on the CO. 2 Steel cylinder, pressurize the system to 36MPa by high pressure pump, when the pressure of extraction kettle and separation kettle reach 36MPa, adjust CO at the same time 2 The flow rate is 15kg / h, and the state of constant temperature, constant pressure, and constant flow rate is maintained for 3 hours of extraction, and the extracted substance is released to obtain 52g of turmeric oil. It was determined that the extraction rate of the prepared turmeric oil was 96.5%, and the product yield was 5.2%.

Embodiment 2

[0012] Pulverize, sieve, and dry turmeric, weigh 1000 g of turmeric powder in the extraction kettle, set the temperature to 50°C, and start heating. When it reaches 45°C, turn on CO. 2 Steel cylinder, pressurize the system to 35MPa by high pressure pump, when the pressure of extraction kettle and separation kettle reach 35MPa, adjust CO at the same time 2 The flow rate is 14kg / h, and the state of constant temperature, constant pressure, and constant flow rate is maintained for 2 hours of extraction, and the extracted substance is released to obtain 50g of turmeric oil. The extraction rate of the prepared turmeric oil was 92.78%, and the product yield was 5.0%.

Abstract

The invention relates to a preparation method of curcuma oil and belongs to the field of food additives and preparation methods thereof. The preparation method comprises the following steps: grinding curcuma, screening, drying, weighing a certain amount of curcuma powder in an extraction kettle, setting the temperature, opening a CO2 steel bottle when the set temperature is reached, pressurizing a system through a high-pressure pump, adjusting the CO2 flow to reach a certain value when the pressure of the extraction kettle and a separation kettle reaches a selected value, extracting for a certain time in a state of keeping constant temperature, constant pressure and constant flow, and discharging extract, namely the curcuma oil. According to the preparation method, the curcuma oil is extracted by a supercritical CO2 extraction process; compared with a conventional method, the curcuma oil has the advantages of high purity, high yield, high quality and the like, the preparation method is simple in process, strong in operability and suitable for industrialized production, and the prepared curcuma oil has the extraction rate of 96.5% and the product yield of 5.2%.

Description

technical field [0001] The invention relates to a preparation method of turmeric oil, and belongs to the field of food additives and preparation methods thereof. Background technique [0002] Turmeric oil is an important food additive and one of the main components of turmeric. Turmeric tubers contain about 4% to 6% of turmeric oil. Pharmacological studies have shown that turmeric oil has good antioxidant, antibacterial and anti-mutation effects. The traditional methods of extracting turmeric oil mainly include steam distillation and organic solvent extraction. Due to the higher temperature of the water vapor in the steam distillation method, the spice with a low boiling point in the turmeric oil is easily destroyed, and the component with a high boiling point is not easily steamed out, and the distillation time is also long and other shortcomings; the use of organic solvents to extract ginger Butter has problems such as residual organic solvent and large solvent consumptio...
