Problems solved by technology

The advantage of this method is that the cost is low, and the disadvantage is that the extraction rate is low.
[0005] Due to the lack of research on the oil of the black soldier fly, the poor extraction process, and the lack of utilization at present, there is still a broad space for the application and development of the black soldier fly

Embodiment 1

[0026] (1) Pretreatment of black soldier fly larvae

[0027] Soak the collected black soldier fly larvae in water for 30 minutes, make them spit out the undigested debris in the intestinal tract through self-purification, wash with clean water once, filter out the water and collect the worm bodies for later use;

[0028] (2) Drying of black soldier fly larvae

[0029] Drying conditions: power 12KW, time 15min;

[0030] (3) the black soldier fly larva dry product is pulverized, crosses 20 mesh sieves;

[0031] (4) Extraction

[0032] Weigh 10kg of the sieved black soldier fly powder and put it into the extraction kettle, close the valve, and pump in CO 2 gas. Extraction conditions: pressure 25Mpa, temperature 40°C, time 2h;

[0033] (5) primary separation

[0034] Open the valve so that the CO 2 The fluid enters the first separation tank from the extraction tank, and the separation conditions are: pressure 10Mpa, temperature 45°C, time 20min;

[0035] (6) Secondary sepa...

[0050] (6) Secondar...

Embodiment 3

[0056] Supercritical CO by gas chromatography 2 The extracted black soldier fly oil was quantitatively analyzed.

[0057](1) Methylation of black soldier fly insect oil: Weigh 0.25g of the insect oil obtained in Example 2 into a 50ml volumetric flask, add an appropriate amount of n-heptane to dissolve, dilute to the mark, and shake well. Accurately draw 2ml of n-heptane solution into a 10ml capped centrifuge tube, add 0.2ml of potassium hydroxide-methanol solution (4mol / L), shake vigorously for more than 1min, and place for 10min. Get the upper layer organic phase solution for subsequent use;

Abstract

The invention provides a method for preparing cosmetic raw materials from Hermetia illucens larvas. The method comprises the procedures of pretreatment, drying, smashing, screening, supercritical CO2 extraction and separation. The method for preparing the cosmetic raw materials has the advantages of being high in extracting efficiency, free of pollution and residues, environmentally friendly and the like, and extracted worm oil is rich in polyunsaturated fatty acid , has the moisturizing and anti-wrinkle effects and other effects on skin and can be used as the cosmetic raw materials.

Description

technical field [0001] The invention belongs to the technical field of insect agricultural product processing, in particular to a method and application for preparing cosmetic raw materials from black soldier fly larvae. Background technique [0002] Black soldier fly (black soldier fly), also known as bright flat-horned soldier fly, belongs to Diptera in insect taxonomy, and is a saprophytic insect that can transform a variety of organic solid wastes. The larvae and pupae of the black soldier fly are rich in essential amino acids and minerals, and have a high oil content. They have been identified as an important feeding resource insect and have been used in the production of animal protein feed, transformation of poultry manure and domestic waste. promote. [0003] At present, the application of black soldier flies in our country mainly stays in the treatment of solid waste. The deep processing of black soldier flies is mainly the preliminary research on drying them into ...
