Embodiment 1

[0031] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:

[0032] 1. Preparation of keratin stock solution by reduction hydrolysis

[0033] Reductive hydrolysis method: Weigh 5g of washed and dried livestock and poultry hair and put it in a flask, add 90g of water and 4g of sodium sulfite to mix, stir for 0.5 to 2 hours, filter out the livestock and poultry hair, wash it with deionized water, add 75g of water and 3g of hydrogen Sodium oxide, heated to 90°C with stirring for 3.5 hours to prepare keratin stock solution.

[0034] 2. Ultrasonic treatment

[0035] The keratin stock solution prepared in step 1 was irradiated with ultrasonic waves with a power of 600W for 3 minutes to prepare a livestock and poultry hair keratin solution.

[0036] 3. Dry

[0037] The livestock and poultry hair keratin liquid is put into a vacuu...

Embodiment 2

[0039] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:

[0040] In the process step 1 of preparing keratin stock solution by reduction hydrolysis method in Example 1, weigh 5 g of washed and dried livestock and poultry hair and place it in a flask, add 50 g of water and 0.05 g of sodium sulfite to mix, stir for 0.5 to 2 hours, and filter out the livestock and poultry hair , and washed with deionized water, added 50 g of water and 0.5 g of sodium hydroxide, heated to 70° C. for 4.5 hours with stirring, and prepared a keratin stock solution. In step 2 of the ultrasonic treatment process, the keratin stock solution prepared in step 1 is irradiated with ultrasonic power of 400W for 6 minutes to prepare a livestock and poultry hair keratin solution. In step 3 of the drying process, the livestock and poultry hair keratin liquid...

Embodiment 3

[0042] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:

[0043]In the process step 1 of preparing keratin stock solution by reducing hydrolysis method in Example 1, weigh 5 g of washed and dried livestock and poultry hair and place it in a flask, add 100 g of water and 7.5 g of sodium sulfite to mix, stir for 0.5 to 2 hours, and filter out the livestock and poultry hair , and washed with deionized water, added 100 g of water and 5 g of sodium hydroxide, heated to 100° C. for 2 hours with stirring, and prepared a keratin stock solution. In step 2 of the ultrasonic treatment process, the keratin stock solution prepared in step 1 is irradiated with ultrasonic power of 400W for 5 minutes to prepare a livestock and poultry hair keratin solution. In the drying process step 3, the livestock and poultry hair keratin liquid is put...

Abstract

Disclosed is a method to prepare and treat keratin from animal hair with ultrasonic, including the procedures of preparing keratin solution through deoxidizing hydrolyzation or oxidizing hydrolyzation, ultrasonic treatment and drying. Compared with the current methods of preparing keratin solution from animal hair, the method introduces ultrasonic to process the keratin solution which is prepared through deoxidizing hydrolyzation or oxidizing hydrolyzation, and is simple in operation, shortens hydrolyzation time and reduces consumption of the chemicals, thus reducing environment pollution. The method is applicable to the preparation of keratin from animal hair. The keratin can be used in the preparation of cosmetics and animal hair keratin composite film material which can be used to replace current plastic package bags; after use, the animal hair keratin composite film material is buried in the ground and can be degradated quickly into fertilizer, thus reducing environment pollution.

Description

technical field [0001] The invention belongs to the technical field of preparing keratin from livestock and poultry hair, and in particular relates to a method for preparing keratin by adopting a reduction ultrasonic hydrolysis method or an oxidation ultrasonic hydrolysis method. Background technique [0002] my country is a large country in animal husbandry and breeding, and a large amount of livestock and poultry hair is discarded every year due to unreasonable utilization. The main component of livestock and poultry hair is keratin, which is difficult to degrade under natural conditions, and it is easy to cause mosquitoes and flies to breed, produce bacteria, viruses, and unpleasant and toxic gases, endangering human health and polluting the environment. Therefore, it is of great significance to study the method of extracting keratin from livestock and poultry hair to effectively utilize natural resources and protect the environment. [0003] The patent publication numbe...
