Claims18
A method of inhibiting spoilage of a volume of milk, the method comprising the step of:
- immersing an anti-spoilage insert at least partially in the volume of milk for a predetermined period of time which is an effective time to inhibit spoilage,
- wherein the anti-spoilage insert comprises silver, wherein the silver is deposited on a substrate.
A method for producing a milk anti-spoilage insert, the method comprising
- agitating a substrate in a precursor solution for at least 30 minutes, wherein the precursor solution comprises at least 0.01M silver nitrate;
- drying the substrate;
- heating the substrate at a temperature of at least 100° C. for at least 30 minutes;
- and
- heating the substrate at a temperature of at least 250° C. for at least 15 minutes.
2 more elements
A method of inhibiting spoilage of milk, the milk having a volume, the method comprising the step of:
- immersing a substrate comprising silver in milk for an effective time to inhibit spoilage;
- wherein the substrate has a substrate weight, wherein the substrate weight is at least 1 mg per mL of the volume;
- wherein the silver is deposited on the substrate, wherein the silver has a silver weight, wherein the silver weight is at least 0.05% of the substrate weight.
