(1)Polycarboxylate se fokotsang metsi se na le limatlafatsi tse ngata bakeng sa ho phela ha libaktheria le likokoana-hloko tse ling. Ha mocheso o phahame, ho ba bonolo hore likokoana-hloko li ikatise, 'me metsoako e sebetsang e sebetsa ka potlakopolycarboxylate metsi a fokotsang metsi a sebelisoa. Ha ho na li-preservatives, ha mocheso oa tikoloho o feta 25℃mme e bolokoe matsatsi a 7, mme ha mocheso o le haufi le 10℃'me e bolokiloe matsatsi a 28, litaba tsa baktheria li boemong ba 10cfu/ml. Ka nako ena, konkreite e na le tahlehelo e kholo ka nako le nako e khutšoanyane ea ho beha.

Likahare tsa baktheria tse fokotsang metsi tse nang le li-preservatives ke <10cfu/ml ka mor'a ho bolokoa ho 9-15.℃bakeng sa matsatsi a 28, 'me 5% e eketsoa. Likahare tsa baktheria tsa ho fokotsa metsi ka sodium metabisulfite ke 10-100cfu / ml ka mor'a ho bolokoa ho 9-15.℃ka matsatsi a 28.
