Example Embodiment
[0018] In this embodiment, the method for preparing an oxygen supply agent that promotes the rapid consumption of sugar by lactic acid bacteria without changing the ventilation control strategy includes the following steps:
[0019] (1) Preparation of saturated sodium hydroxide solution: the saturated sodium hydroxide solution is a saturated sodium hydroxide solution at 0°C.
[0020] (2) Preparation of β-cyclodextrin-hydrogen peroxide mixed aqueous solution at 0℃: H in β-cyclodextrin-hydrogen peroxide mixed aqueous solution 2 O 2 The mass fraction of β-cyclodextrin is 42%, and the mass fraction of β-cyclodextrin is 5%.
[0021] (3) Preparation of sodium peroxide modified solution at 0℃: add oleic acid, propylene glycol oleate and glyceryl oleate to ethyl acetate, stir thoroughly to obtain sodium peroxide modified solution; The mass fraction of the oleic acid in the modified sodium peroxide solution is 25%. The added amount of the propylene glycol oleate is 3% of the mass of the ethy...
