Taupānga

Ko te Polyvinylpyrrolidone e whakamahia nuitia ana i roto i te mara rongoa, a ko tetahi o nga rongoa rongoa hou e toru e tautokohia ana i te ao.Ko nga taapiri e whakamahia nuitia ana ko nga papa me nga kowhatu.Ka taea hoki te whakamahi hei awhina rere mo nga kapene, te whakakore me te whakahinuhinu mo nga raau taero kanohi, he whakarewa tahi mo nga werohanga, he whakamarara mo nga whakaritenga wai, me te whakapumau mo nga enzymes me nga raau taero wera.Ka taea hoki te whakahiato i te povidone me te iodine povidone iodine (PVP-I) waipatu.I roto i nga arotahi whakapiri, ka whakamahia te PVP hei waahanga o nga arotahi whakapiri hei whakanui ake i to raatau hydrophilicity.Ka taea hoki te whakamahi PVP hei whakamarumaru cryogenic i roto i te rongoa.
