Problems solved by technology

At present, the process of using fly maggots as raw materials to extract natural chitin by comprehensive processing technology of physical and chemical processes is still immature. The existing extraction process has complex principles and steps, demanding process conditions, high extraction costs, and poor environmental conditions. The product yield is low and the economic benefit is not obvious

Embodiment 1

[0025] A method for extracting chitin from fruit fly maggots includes the following steps:

[0026] (1) After disinfecting and cleaning the fresh fruit fly larvae, squeeze it with a pressing roller to separate the larva skin from the visceral mass slurry. The larva skin is used as the raw material for extracting chitin, and the larva skin is washed and drained. ,Place in a microwave oven, control the temperature at 75℃, and heat for 15min;

[0027] (2) The dried fly maggot skin obtained in step (1) is placed in a pulverizer for pulverization to obtain fly maggot powder. The fly maggot powder is added to a certain volume of water and stirred to obtain fly maggot slurry, and then the slurry is placed in power The compound protease is added to the 400W ultrasonic device for hydrolysis at a temperature of 55°C for a certain period of time; wherein the mass-volume ratio (g / mL) of the fly maggot meal to water is 1:15; the compound protease is trypsin, Papain and alkaline protease are co...

Embodiment 2

[0031] A method for extracting chitin from fruit fly maggots includes the following steps:

[0032] (1) After disinfecting and cleaning the fresh fruit fly larvae, squeeze it with a pressing roller to separate the larva skin from the visceral mass slurry. The larva skin is used as the raw material for extracting chitin, and the larva skin is washed and drained. ,Place in a microwave oven, control the temperature at 70℃, and heat for 20min;

[0033] (2) The dried fly maggot skin obtained in step (1) is placed in a pulverizer for pulverization to obtain fly maggot powder. The fly maggot powder is added to a certain volume of water and stirred to obtain fly maggot slurry, and then the slurry is placed in power In a 500W ultrasonic device at a temperature of 50°C, a compound protease is added for hydrolysis for a certain period of time; wherein the mass-volume ratio (g / mL) of the fly maggot powder and water is 1:20; the compound protease is trypsin, Papain and alkaline protease are co...

Embodiment 3

[0037] A method for extracting chitin from fruit fly maggots includes the following steps:

[0038] (1) After disinfecting and cleaning the fresh fruit fly larvae, squeeze it with a pressing roller to separate the larva skin from the visceral mass slurry. The larva skin is used as the raw material for extracting chitin, and the larva skin is washed and drained. ,Place in a microwave oven, control the temperature at 80℃, and heat for 10min;

[0039] (2) The dried fly maggot skin obtained in step (1) is placed in a pulverizer for pulverization to obtain fly maggot powder. The fly maggot powder is added to a certain volume of water and stirred to obtain fly maggot slurry, and then the slurry is placed in power In a 300W ultrasonic device at a temperature of 60°C, a compound protease is added for hydrolysis for a certain period of time; wherein the mass-volume ratio (g / mL) of the fly maggot powder and water is 1:10; the compound protease is trypsin, Papain and alkaline protease are co...

Abstract

The invention provides a method for extracting chitin from fruit fly maggots. The method mainly comprises the following processing steps of disinfecting, cleaning, removing protein, removing calcium, and discoloring. The chitin prepared by the processing steps has the advantages that the quality is higher; the yield rate of chitin is high, and reaches 81.80% or above by the content of chitin in fly maggot; the nitrogen content is high and reaches 6.32% or above, the ash content is low and is only 0.09 to 0.16%, and the water content is low and is only 0.6%; the discharge of wastes in processing steps is small, the processing steps are simple and feasible, and the larger prospect is provided for the industrialized application.

Description

Technical field [0001] The invention belongs to a method for extracting and separating effective ingredients from fruit flies, and specifically relates to a method for extracting chitin from fruit fly maggots. Background technique [0002] Drosophila is called "fruit fly" or "vinegar fly" in English, and its taxonomic status is the Drosophilidae Drosophilidae insect from the order Diptera. There are about 4,555 species of Drosophila, and the common Drosophila melanogaster (Drosophila melanogaster) is generally used as a model organism. Drosophila insects are widely distributed in temperate and tropical regions and are highly adaptable. Different species have different feeding habits. They often suck molasses on mature melons or decaying plants to obtain nutrients. They can also feed on sap or pollen. The main food is yeast that can survive both aerobic and anaerobic conditions. The reason why people find fruit flies in orchards, vegetable farms, canteen’s scrap buckets and home...
