preparation example Construction

[0023] The present invention provides a kind of preparation method of micro-nano fishbone-based toothpaste, comprising the following steps:

[0024] Select fish bones and cut them into sections;

[0025] Rinse and remove impurities;

[0026] making fishbone meal;

[0027] Make nano-scale fish bone meal;

[0028] Making micro-nano fish bone-based toothpaste.

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with specific embodiments.

[0030] A preparation method of micro-nano fishbone-based toothpaste, comprising:

[0031] Step 1: Select fish bones and cut them into sections;

[0032] This step can be specifically carried out as follows: remove the minced meat from the fish bone with a knife, and cut each section into small sections with a length of 0.8-1.2 cm to obtain the initial processing section of the fish bone.

Embodiment 2

[0048] This implementation case shows a preparation method of a micro-nano fishbone-based toothpaste according to the following steps:

[0049] Use a knife to remove the minced meat from the discarded fish bones, and cut into small pieces of about 1cm. Rinse to remove impurities, hydrolyze with 3% subtilisin at 60°C for 5h, then cook at 125°C under high pressure at 350MPa for 60min. After taking it out, it is pulverized by a tissue pulverizer, and the pulverization particle size requires passing through a 120-mesh sieve to obtain fishbone meal. Place in an ultra-low temperature refrigerator, the freezing temperature is -60°C, and the processing time is 24h. The coarse powder after freezing is puffed and dried with a vacuum microwave oven, the microwave power is 1000W, and the processing time is 30min, to obtain nano-scale fishbone powder with a particle size concentrated at 80nm. The micro-nano fish bone-based toothpaste is composed of the following components by weight rati...

Embodiment 3

[0051] This implementation case shows a preparation method of a micro-nano fishbone-based toothpaste according to the following steps:

[0052] Use a knife to remove the minced meat from the discarded fish bones, and cut into small pieces of about 1cm. Rinse to remove impurities, hydrolyze with 2% subtilisin at 50°C for 4h, then cook at 120°C under high pressure at 300MPa for 50min. After taking it out, it is pulverized by a tissue pulverizer, and the pulverization particle size requires passing through a 120-mesh sieve to obtain fishbone meal. Place in an ultra-low temperature refrigerator, the freezing temperature is -50°C, and the processing time is 18h. The frozen coarse powder is puffed and dried in a vacuum microwave oven, the microwave power is 700W, and the processing time is 20min, to obtain nano-scale fishbone powder with a particle size concentrated at 40nm. The micro-nano fish bone-based toothpaste is composed of the following components by weight ratio: 60 parts o...

Abstract

The invention discloses a micro-nano fish bone based toothpaste preparation method which comprises the steps: choosing fish bones and cutting the fish bones into sections; rinsing and removing impurities; preparing fish bone coarse powder; preparing nano-scale fish bone powder; preparing micro-nano fish bone based toothpaste. According to the micro-nano fish bone based toothpaste preparation method disclosed by the invention, waste fish bones are micro-nano treated to prepare hydroxyapatite, and the hydroxyapatite is mixed with a foaming agent, a humectant, a sweetening agent, an adhesive, a disincrustant and the like to prepare toothpaste; thus, higher value application of the waste fish bone is achieved; meanwhile, the toothpaste disclosed by the invention can effectively inhibit oral bacteria, protect teeth and freshen breath and is further suitable for dental ulcer patients to relieve symptoms of gingival pain and swelling and the like.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a preparation method of micro-nano fishbone-based toothpaste. Background technique [0002] Hydroxyapatite is the main inorganic component of human bone tissue. After implanted in the body, calcium and phosphorus will dissociate from the surface of the material to be absorbed by body tissues and grow new tissues. Studies have shown that the finer the grain size of hydroxyapatite, the higher the biological activity. The main component of tooth surface enamel is also made of hydroxyapatite, and the content of hydroxyapatite in human tooth enamel is more than 96%. Hydroxyapatite has excellent biocompatibility, and can be used as a bone or tooth inducing factor, and has good remineralization, desensitization and whitening effects on teeth in the field of oral health care. Experiments have proved that hydroxyapatite particles have good biocompatibility and high affinity with toot...
