Lokacin da sitaci tsakiyan nonon kafa yawan amfani carbohydrates

Fassara daga Jamus, sitaci nufin "karfi gari". Kamar yadda wani hadadden halitta polymer, sitaci kunshi biyu polymers: amylose (25%) kuma amylopectin (75%). Azahiri sitaci ne a farin m, da ciwon ba dandano da wari, kusan insoluble a ruwan sanyi amma busa a cikin ruwan zafi, haka nemowa da kaddarorin na manna. Lokacin da compressing yatsunsu fararen foda fitarda halayyar creaking. Lokacin da kyan gani, a karkashin wani microscope, za ka iya ganin granular tsarin sitaci.

Da farko, a lokacin da tsagawa na sitaci da aka kafa polysaccharide dextrin - wani samfurin na m hydrolysis na sitaci. Dextrins iya samun ta m dumama na sitaci dauke 10-20% ruwa.
