Problems solved by technology

The structure and properties of the synthesized interpenetrating colloid (interpenetrating hydrogel) are controllable and reproducible, but the biocompatibility is poor
The disadvantages of traditional structural hydrogels also include slow response rate and low mechanical strength.
Interpenetrating hydrogels are widely used in biomedical materials, petrochemicals, agriculture, and daily cosmetics, but there are few researches and applications on oral or edible interpenetrating hydrogels

[0087] ③Preparation of semi-interpenetrating colloids: After the mixture in Gel-1~Gel-4 is completely dissolved, immediately add 100mg mTG and vortex until mTG is completely dissolved;

[0088] ④ Determination of rheological properties: Move the mixture immediately to a rheometer plate preheated to 40°C, and use a 40mm plate test head to measure the elastic modulus (G') and viscous modulus (G") during the gelation process of the colloid Rheometer parameter setting: measuring time 40min, measuring frequency 1Hz, measuring strain force 1%;

[0089]⑤Add 5mg T-SDF, 10mg T-SDF, and 20mg T-SDF to Gel-5~Gel-7 respectively, add 900μL deionized water, and vortex for 2-3min, add the rotor and place it in a water bath at 55°C and heat to dissolve. And carry out magnetic stirring until the gelatin and T-SDF are completely dissolved;

[0090] ⑥Preparation of interpenetrating colloids: After the mixture in Gel-5~Gel-7 is completely dissolved, immediately add 100mgmTG and 100μL 50mmol / L cal...

Abstract

The invention provides tomato peel soluble dietary fiber interpenetrating colloid and a preparation method thereof. Concretely, the interpenetrating colloid provided by the invention has excellent elastic modulus, viscous modulus and hardness, and also has the characteristics of low cost, environment-friendly effect, high safety coefficient and natural ingredients.

Description

technical field [0001] The invention relates to a medical material containing interpenetrating colloid, in particular to an interpenetrating colloid of tomato peel soluble dietary fiber and a preparation method thereof. Background technique [0002] Tomato is the vegetable variety second only to potato in terms of consumption. During the processing of tomato sauce and tomato juice, 4-5% of tomato peels will be produced. Tomato peels contain soluble dietary fiber with high utilization value, but have not been used. Effective development and comprehensive utilization not only cause economic waste, but also cause environmental pollution due to dumping. [0003] At present, natural interpenetrating colloids (interpenetrating hydrogels) have certain limitations due to differences in structure and properties between batches due to different sources. The structure and properties of the synthesized interpenetrating colloids (interpenetrating hydrogels) are controllable and reproduc...
