Chicken Feet Collagen in the Chocolate Industry
Industrial Extraction of Collagen from Chicken Feet
The industrial extraction of collagen from chicken feet is an important process in the food and pharmaceutical industries. Collagen is a structural protein found in connective tissues, skin, and bones. Below are the general steps involved in this process:
Steps for Extracting Collagen from Chicken Feet
Collection and Preparation of Raw Materials:
Chicken feet are collected after slaughter.
Skin and excess tissue are removed from the feet.
Cleaning:
The feet are carefully washed to eliminate any dirt and bacteria.
Disinfectant solutions may be used.
Cooking:
The feet are boiled in hot water or steamed to release collagen from the connective tissues.
This stage is usually conducted at high temperatures for a specified duration.
Extraction:
After cooking, collagen is extracted using various methods such as solvent extraction or enzymatic methods.
This stage may require several rounds of extraction to achieve higher purity.
Filtration and Purification:
The collagen extract is filtered, and impurities are separated.
Methods such as microfiltration or nanofiltration are commonly employed.
Drying:
The purified collagen is dried into powder or a dry solution.
This step may involve spray drying or vacuum drying.
Packaging:
The final collagen is packaged in suitable containers for distribution and sale.
Applications
Food Industry: As a nutritional supplement and for gelatin production.
Pharmaceutical Industry: In the production of drugs and medical formulations.
Beauty Industry: In skincare and anti-aging products.
The extraction of collagen from chicken feet is a complex process that requires specialized equipment and adherence to hygiene standards.
What types of solvents are used in the extraction phase?
In the collagen extraction phase from chicken feet, various solvents and methods are used to extract collagen. Some of these solvents and methods include:
Hot Water:
One traditional method for extracting collagen is the use of hot water. Heat helps release collagen from connective tissues.
