Answer to Question #87768 in Human Anatomy and Physiology for Shyanne Willard

Question

Hi I am not sure if this is the correct place or not but I figured you might have some answers. I am looking to preserve and then hopefully plastisize milk more specific human breast milk. Do you know what kind of preservative I could use for it, it has a pH level of roughly 7.5 and how could I plastisize it afterwards, or will plastisizing cause the preservative to not work properly?

Answer 1

Possible preservatives:

E-201 Sodium Sorbate

E-202 Potassium Sorbate

E-203 Calcium sorbate

E-210 Benzoic Acid

E-211 Sodium Benzoate

E-212 Potassium Benzoate

E-213 Calcium Benzoate

E-214 Ethyl p-hydroxybenzoate

E-224 Potassium Metabisulphite

E-225 Potassium Sulphite

E-226 Calcium Sulphite

E-227 Calcium Hydrogen Sulphite

E-230 Biphenyl, biphenyl

E-235 Natamycin (Pimaricin)

E 237 Sodium Formate

E 238 Calcium Formate

E-249 Potassium Nitrite

E-250 sodium Nitrite

E-251 sodium Nitrate

E-252 Potassium Nitrate

E-261 Potassium Acetate

E-262 Sodium Acetates 

E-263Calcium Acetate

E-266 sodium Dehydroacetate

E-281 sodium Propionate

E-282 Calcium Propionate

E-283 Potassium Propionate

E-285 Sodium Tetraborate (Borax)

These are all preservatives that can create pH 7.5 but the concentration of some of them can be high (more than 1% by milk wieght)
