Hemicelluloses-ka qaar ayaa inta badan ku jira xaddi yar oo sonkoro kale ah, sida L-arabinose, D-glucose, D-galactose, D-mannose, D-glucuronic acid iyo D-galacturonic acid, iwm, kuwaas oo inta badan lagu tallaalo silsilado laamo ah. Hemicellulose waxa ay ku milmi kartaa alkali-ka milmi waxana laga sooci karaa cellulose.

Ku saabsan Hemicellulose
Hemicellulose waa heteropolymer ka kooban dhowr nooc oo kala duwan oo monosaccharides ah, kuwaas oo ah sonkor shan iyo lix kaarboon ah, oo ay ku jiraan xylose, arabinose, iyo galactose.
Hemicellulose waxay si ballaaran ugu jirtaa dhirta waxayna inta badan u shaqeysaa sidii qalfoofka. Marka dhirtu si xoog leh u firfircoonaato, sida marka iniinuhu soo baxaan, sidoo kale waa la nadiifin karaa si ay u sameeyaan monosaccharides si ay u bixiyaan nafaqooyinka loo baahan yahay koritaanka dhirta.
Hemicellulose waa nooc ka mid ah heteropolysaccharide ka jira gidaarka unugyada dhirta. Hemicellulose waxaa lagu soo saari karaa xalalka alkali ee la milo ah. Marka hemicellulose lagu hydrolyzed asiidh-diluten, sonkor hexose kala duwan, sonkorta pentose iyo uronic acids ayaa la heli karaa. Halabuurka hemicellulose waa mid aad u adag. Hemicellulose waxaa ku jira polysaccharides sida xyloglucan, glucuronoxylan, mannan iyo galactan, sidaa darteed hemicellulose waa nooc ka mid ah heteropolysaccharide. Hemicellulose ee ku jira badarka shaciirku waa inta badan isku dhafka xylan iyo polyarabinose; hemicellulose oo ku jira digriiga konjac waxa ay u badan tahay polyglucomannose (Polyglucomannose waxa uu leeyahay qiimo dawo oo aad u sarreeya iyo qiimaha cuntada, waxana uu dhib u geystaa jidhka bini’aadamka, waxa uu leeyahay saamayn caafimaad oo kala duwan, waxana loo isticmaali karaa in lagaga hortago calool-istaagga, hoos u dhaca sonkorta dhiigga, hoos u dhaca dufanka dhiigga. , miisaankaaga dhimo oo la dagaallamo kansarka).
Hemicellulose waa heteropolysaccharide oo la wadaaga cellulose ee gidaarada unugyada dhirta inteeda badan, waxayna si weyn ugu jirtaa qaybaha dhirta. Hemicellulose xylan, oo ka dhigan 50% wadarta unugyo alwaax ah, waxay ku xidhan tahay dusha sare ee microfibrils cellulose iyo isku xidhka, iyo fiilooyinkani waxay sameeyaan shabakad adag oo unugyo isku xidhan.
Hydrolysis co-thermal ee hemicellulose iyo aashitada xoogga leh waa hab warshadeed oo loogu talagalay diyaarinta furfural. Waxaa lagu shubaa aashitada dilution si loo helo xylose, taas oo ah alaabta ceeriin ee ugu weyn ee diyaarinta xylitol.
