Lijo tse teteaneng ke e 'ngoe ea li-excipients tsa bohlokoa ka ho fetisisa indastering ea lijo, eo haholo-holo e bapalang karolo ea ho tsitsisa mokhoa oa lijo ho lokisa lijo, joalo ka ho boloka botsitso ba slurry e emisitsoeng, botsitso ba tekanyo ea boreleli, le botsitso ba tsamaiso ea emulsion.

Ho phaella moo, e ka ntlafatsa ho ama lijo le botsitso ba 'mala, monko, tatso le boemo ba metsi a lijo tse entsoeng. Karolo e hlahelletseng ea "thickener" t?ebetsong ea lijo e bonahala haholo maemong a latelang.

Li-thickeners tsa lijo ke li-polymers tsa hydrophilic. Soluble ka metsing e na le viscosity e kholo, e le hore tsamaiso e be le maikutlo a teteaneng. Ha viscosity ea tsamaiso e ntse e eketseha, karolo e qhalakaneng tsamaisong ha e bonolo ho kopanya le ho kopanya, kahoo e ka etsa hore tsamaiso e qhalakaneng e tsitsitse. Li-thickeners tse ngata li na le ts'ebetso ea surfactant, li ka adsorbed holim'a karolo e qhalakaneng, e le hore e be le hydrophilicity e itseng 'me ho bonolo ho e hasanya ka mokhoa o ts'oanang tsamaisong ea metsi.

Li-thickeners tse ling, tse kang gelatin, AGAR le litharollo tse ling, ke maro a viscous tlas'a maemo a futhumetseng. Ha mocheso o fokotsehile, limolek'hule tsa tharollo li kopantsoe ka mohaho oa marang-rang, li-solvents le mecha e meng ea ho qhalakanngoa kaofela li kenyelelitsoe mohahong oa marang-rang, 'me tsamaiso eohle e etsa semi-tiileng ntle le ho tsamaea, ke hore, gel. Mefuta e mengata ea ho lokisa lijo ke ho sebelisa t?obotsi ena ea motenya, joalo ka leqhoa, custard joalo-joalo.

Li-thickeners tse ngata ke tsa thepa ea polymer, 'me tlas'a maemo a itseng, mecha ea phatlalatso e mengata e ka kenngoa ka nako e le' ngoe ho bokella le ho arohana, e le ho finyella morero oa ho hloekisa kapa ho hloekisa. Haeba palo e nyenyane ea gelatin e kenngoa ka lero, lero le hlakisitsoeng le ka fumanoa.

Phello ea hydrophilic ea thickener e ka ntlafatsa boleng ba lihlahisoa tsa nama le phofo. Lijong tsa li-noodle, motenya o ka ntlafatsa ho monya ha metsi ha hlama, 'me motenya o ka potlakisa lebelo la ho kenella ha metsi ka har'a limolek'hule tsa protheine le likaroloana tsa starch ha hlama e lokisoa, e leng se loketseng mokhoa oa ho kopanya phofo. Ka lebaka la thepa ea gel ea thickener, viscoelasticity ea lihlahisoa tsa phofo ea ntlafatsoa, ??tekanyo ea starch αization ea eketseha, 'me ha ho bonolo ho tsofala le ho omella.

T?ebeliso ea "thickener" e ka etsa hore lijo li be le viscosity e phahameng, e le hore tharollo kapa tsamaiso ea supersaturated e se ke ea bonahala e le crystallization kapa crystallization ho finyella phello e ntle. Ka mohlala, laola ts'ebetso ea lehlabathe la lihlahisoa tsa sirapo le ho thibela likristale tsa leqhoa lijong tsa ice cream.

Lijo tse teteaneng li ka etsa filimi e sireletsang e boreleli haholo holim'a lijo, ho sireletsa lijo ho tsoa ho oksijene le likokoana-hloko. E ka thibela ho theoha ha boleng bo bakoang ke ho monya ha mongobo oa holim'a lijo tse hatselitsoeng le phofo e tiileng.

The thickener e ka foamed ho etsa sebopeho sa marang-rang. Likuku, baapehi, ice cream le t?ebeliso e 'ngoe ea algin, tsie linaoa gum, sodium alginate, gelatin e le mahlahana a foaming, mahlahana a thickening ka ntlafatsa palo ea foam le bubble botsitso, tse kang biri bubble le lebota la botlolo "moriri" ke lebaka la ho sebelisoa ha mahlahana a thickening.

Sepheo sa ho sebelisa tsie bean gum le algin gum ka boroso ke ho etsa hore sehlahisoa se be agglomeration, sebopeho sa lisele se tsitsitse le ho tlotsoa ka mor'a homogenization, 'me matla a ho boloka metsi a sekhomaretsi a sebelisetsoa ho thibela boroso ho lahleheloa ke boima ba polokelo. Gum Arabic e ka sebelisoa e le setlamo sa letlapa le lihlahisoa tsa granular, ka granulation ea lijo tsa phofo, granulation ea linoko tsa lijo le lisebelisoa tse ling.
