Embodiment 1
[0023] (1) Preparation of fruit juice culture solution: wash the silt and impurities on the peel of discarded oranges with running water, beat the pulp with a beater and peel off the peel, and wrap the fruit pulp with cloth to extract the juice; the juice after coarse filtration is filtered through a centrifugal filter , Separation, remove the remaining peel, seeds, part of the fiber, crushed pulp and impurities. The pH of the juice was adjusted to 4.5 using sodium dihydrogen phosphate buffer, the juice was sterilized, and then stored at -5°C for future use.
[0024] (2) Preparation of bacterial cellulose: select the above-mentioned orange juice culture solution prepared after dilution of 2 times as a culture medium; inoculate Acetobacter xylinum with 0.1wt% inoculum, carry out constant temperature cultivation at 30°C, and carry out bacterial cellulose production within 7 days Production.
[0025] (3) The obtained bacterial cellulose was rinsed and deacidified, then boiled in...
Embodiment 2
[0027] (1) Preparation of fruit juice culture medium: pour the discarded apple fruit after washing into the squeezer to squeeze the juice, and then filter the peel, fruit seeds and some crude fibers through a scraper filter; the juice after the rough filtration is centrifuged Machine filtration and separation to remove residual peel, fruit seeds, some fibers, crushed pulp and impurities to obtain juice without solid particles; use sodium dihydrogen phosphate buffer to adjust the pH of the juice to 3.5, and sterilize the juice. Then store at -20°C for later use;
[0028] (2) Preparation of bacterial cellulose: select the above-mentioned prepared apple juice culture solution diluted 5 times, add 2wt% yeast extract and 0.1wt% sodium citrate to the culture solution, and sterilize again as a culture medium ; Inoculate lactic acid bacteria with 0.5wt% inoculation amount, carry out constant temperature cultivation at 32° C., and carry out bacterial cellulose production within 14 days...
Embodiment 3
[0031] (1) Preparation of pomace culture solution: Saccharify the waste orange peel and the residues in the fruit juice preparation process to obtain a saccharification solution, use sodium dihydrogen phosphate buffer to adjust the pH of the saccharification treatment solution to 3.7, and carry out the saccharification treatment solution. Sterilize, then store at -10°C for later use;
[0032] (2) Preparation of bacterial cellulose: select the above-mentioned prepared orange pomace culture solution after being diluted 8 times, add 5wt% concentration to be 30wt% sugar water, 0.6wt% ammonium sulfate in this culture solution, and sterilize again as Culture medium: Acetobacter xylinum is inoculated with an inoculum amount of 0.8 wt%, and cultured at a constant temperature of 30° C., and the production of bacterial cellulose is carried out within 12 days.
[0033] (3) The obtained bacterial cellulose was rinsed and deacidified, then boiled in 10wt% sugar water, and soaked in sugar w...
