Agar ndi zouma, hydrophilic, colloidal polysaccharide complex yotengedwa mu agarocytes algae wa Rhodophyceae. Kapangidwe kameneka kamakhulupirira kuti ndi mitundu yambiri ya maunyolo a polysaccharide okhala ndi ma alternating a-(1!3) ndi b-(1!4) maulalo. Pali mitundu itatu yopitilira muyeso yodziwika: yomwe ndi agarose osalowerera ndale; pyruvated agarose yokhala ndi sulfation pang'ono; ndi galactan ya sulphate. Agara amatha kupatulidwa kukhala gawo lachilengedwe la gelling, agarose, ndi kagawo kakang'ono ka sulfate, agaropectin. Ntchito M'malo mwa gelatin, isinglass, etc. popanga emulsions kuphatikizapo zithunzi, gels mu zodzoladzola, ndi monga thickening agent mu zakudya makamaka. confectionery ndi mkaka; mu zowotchera nyama; kupanga encapsulations mankhwala ndi mafuta; monga maziko a nkhungu ya mano; ngati dzimbiri inhibitor; kukula kwa silika ndi pepala; mu utoto ndi kusindikiza nsalu ndi nsalu; mu zomatira. Muzakudya zofalitsa zikhalidwe za bakiteriya.
