NOVELTY - A bacteriostatic constant pressure deoxidizer comprises 50-70 wt.% oxygen removal component, 15-25 wt.% carbon dioxide release component and 15-25 wt.% bacteriostatic component. The oxygen removal component comprises at least one of ascorbic acid, D-sodium erythorbate and D-calcium erythorbate and additive materials. The carbon dioxide release component comprises sodium carbonate, sodium bicarbonate and embedded organic acid. The bacteriostatic component comprises sodium diacetate, alcohol and graphene. USE - Bacteriostatic constant pressure deoxidizer used in food packaging product for packaging bread, cake or rice and flour products (all claimed). ADVANTAGE - The three components of oxygen absorption, carbon dioxide release and antibacterial substance release are combined to achieve triple antibacterial protection effects. The deoxidizer prepared by the method has stable and controllable effect, widens the antibacterial spectrum to microorganisms, does not need to be added into food, has high raw material safety, does not influence the flavor of the food, and improves the food safety. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of bacteriostatic constant pressure deoxidizer, which involves stirring and mixing the additive material, graphene and alcohol to obtain mixture (A), placing the mixture (A) in sealed container, stirring and mixing the sodium carbonate and sodium bicarbonate to obtain mixture (B), stirring and mixing the ascorbic acid, D-sodium erythorbate, D-calcium erythorbate, embedded organic acid and sodium diacetate to obtain mixture (C), and stirring the mixture (A), mixture (B) and mixture (C); and application of bacteriostatic constant pressure deoxidizer, which is packaged using breathable bag and adding into food packaging product.
