However, such a preservation method still cannot obtain a good preservation effect. In addition, this method consumes a large amount of acid, and the biocellulose hydrogel product needs to be rinsed with a large amount of water before use, which is cumbersome to operate and wastes resources. , and for biocellulose hydrogels that often need to be transported on a large scale, vacuum packaging and low temperature storage will undoubtedly greatly increase the production cost of biocellulose hydrogels

Embodiment 1
[0020] Embodiment 1: the preparation of biocellulose hydrogel product
[0021] Biocellulose hydrogel was prepared by static shallow plate fermentation method (the inoculum of Gluconoacetobacter xylinum was 8% by weight, 28°C, fermented for 5 days), and the harvested hydrogel film was repeatedly rinsed with weak alkaline water and deionized water , remove the culture medium components and impurities attached thereto, and obtain the biological cellulose hydrogel membrane fermented in a static pan.
[0022] The biocellulose hydrogel was prepared by dynamic fermentation method (the inoculum of Gluconoacetobacter xylinum was 10% by weight, 29°C, fermented for 7 days), and the harvested hydrogel pellets were rinsed repeatedly with weak alkaline water and deionized water, The culture medium components and impurities attached thereto are removed to obtain biocellulose hydrogel pellets fermented in a static pan.

Abstract
The invention relates to a biological cellulose hydrogel preservation method and a biological cellulose hydrogel product stored through the method. The method comprises the steps: soaking biological cellulose hydrogels in a liquid preservative, and packing the biological cellulose hydrogels together in the liquid preservative, wherein the liquid preservative contains triclosan and an anionic surfactant. The anionic surfactant is lauryl sulfate or lauryl sarcosinate of an alkali metal or ammonium. An excellent preservation effect is achieved after the method is used to preserve the biological cellulose hydrogels, and the storage life of the biological cellulose hydrogels is also prolonged to 40 weeks without vacuum sealing at the normal temperature. By using the method provided by the invention, the biological cellulose hydrogel product does not need to be rinsed with a large amount of water before use and can be directly used, the preservation method is convenient and economical, and the use cost of the biological cellulose hydrogel product is further reduced.
Description
technical field [0001] The invention relates to a method for preserving biological cellulose hydrogels, in particular to a method for preserving biological cellulose hydrogels using a compound preservative. [0002] Background technique [0003] Biocellulose (Biocellulose, BC), also known as bacterial cellulose (Bacterial cellulose,), is a cellulose product with high purity. Compared with natural cellulose, it has strong adsorption performance, flexibility and biodegradability due to its ultra-fine spatial network structure. At present, it has been widely used in food, medicine and other fields. The preparation of biological cellulose is obtained by static shallow plate fermentation culture or dynamic fermentation culture of microorganisms such as Acetobacter. Static shallow plate fermentation culture method can obtain hydrogel-like biocellulose film products on the surface of liquid medium, and dynamic fermentation Cultivation yields small spherical biocellulose hydrogel...
