Embodiment Construction

[0028] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0029] A tussah silkworm chrysalis oil ultrasonically enhanced supercritical CO 2 The preparation process of extraction is characterized in that: the steps of the preparation process are:

[0030] (1). Raw material pretreatment: use the tussah silkworm chrysalis of the genus Tussah species produced in Dandong City, Liaoning Province, and the variety is "Kangda". Tussah silkworm chrysalis powder.

[0031] (2). Put the tussah silkworm chrysalis powder obtained in step (1) into the extraction kettle, and when the temperature reaches 40-50°C, turn on the CO 2 Air is supplied from the cylinder, and when the extraction pressure reaches 18-25MPa, the flow rate is adjusted, and tussah silkworm chrysalis oil is extracted at constant temperature and...

Abstract

The invention relates to a preparation process for ultrasonic reinforced supercritical CO2 extraction of tussah pupa oil. The process comprises the following steps of: (1) pre-treating raw materials, namely sorting, cleaning, sterilizing and freeze-drying tussah pupas and crushing the tussah pupas into tussah pupa powder by adopting a high-speed crusher; (2) putting the tussah pupa powder obtained in the step (1) into an extraction kettle, opening a CO2 gas bottle when the temperature reaches 40 to 50 DEG C to blow gas, adjusting the flow when the extraction pressure reaches 18 to 25MPa, and extracting the tussah pupa oil for 60 to 120 minutes at constant temperature under constant pressure; (3) emitting ultrasonic wave to the supercritical CO2 fluid in the extraction kettle by adopting a built-in insertion ultrasonic reinforcing mode in the step (2) to reinforce the tussah pupa oil extraction process; and (4) collecting the tussah pupa oil at the outlet of a separation kettle. The preparation process can remarkably improve the production efficiency, save the production cost and reduce the production energy consumption, and has large-scale industrialized application prospect. The invention also relates to an ultrasonic reinforced supercritical CO2 extraction system for the tussah pupa oil. The system has the predominant advantages of reasonable design, convenience for control, high production efficiency, low energy consumption and the like.

Description

technical field [0001] The invention relates to a functional food preparation process, in particular to an ultrasonically enhanced supercritical CO 2 Extraction preparation process and system. Background technique [0002] In the 21st century, insects will become the third largest source of protein after microorganisms and cell organisms. Insect functional food is a hot spot in the world's food industry in the 21st century, and its nutritional and functional properties have been unanimously recognized by experts at home and abroad. Insect fever is about to begin. [0003] Tussah silkworm is a kind of silk insect with high economic value, which belongs to Arthropoda, Insecta, Lepidoptera, and Cephalidae. It goes through four metamorphosis stages: egg, larva, pupa, and adult. It is a complete metamorphosis insect. . Insects of the Cephaloidae family can be called giants in the insect world, and their huge individuals are more suitable for eating and processing. [0004] T...
