Erythritol muaj crystallinity zoo thiab tsis tshua muaj hygroscopicity. Nws tsis nqus noo noo txawm nyob ntawm qhov txheeb ze av ntawm 90%, thiab nws ruaj khov heev rau cua sov thiab kua qaub. Solubility ntawm erythritol yog tsawg, tsuas yog 37% ntawm 20 ℃. Thaum yaj hauv dej, nws nqus tau ntau lub zog, thiab qhov kub ntawm kev tawg yog -97.4J / g.

Qhov qab zib ntawm erythritol yog 70% mus rau 80% ntawm sucrose, nrog lub teeb saj tshwj xeeb rau qab zib cawv, thiab nws qhov qab zib muaj lub sijhawm nyob hauv lub qhov ncauj luv heev. Thaum sib xyaw nrog qee cov khoom qab zib siab xws li aspartame thiab potassium acetylsulfonamide (AK), qhov qab zib thiab saj zoo ib yam li sucrose. Crystalline erythritol muab qhov kev xav tshiab thaum noj. Lub tshav kub ntawm kev sib cais ntawm erythritol yog kwv yees li peb zaug ntawm cov piam thaj thiab ob zaug ntawm sorbitol.

Erythritol muaj zog tiv thaiv tshav kub thiab yuav tsis decompose los yog hloov xim txawm nyob rau hauv kub kub. Erythritol tsis tau txais cov tshuaj tiv thaiv Maillard thaum koom nrog cov amino acids.

Lub hygroscopicity ntawm erythritol yog qhov tsawg kawg nkaus, thiab nws yog qhov qis tshaj ntawm cov khoom qab zib xws li qab zib cawv thiab dais qab zib. Nyob rau hauv ib cheeb tsam nrog ib tug kub ntawm 20 ℃ thiab ib tug txheeb ze av noo ntawm 90%, tom qab tso tseg rau 5 hnub, hygroscopic hnyav nce yog li 40% rau sorbitol, 17% rau maltitol, 10% sucrose, thiab tsawg tshaj li 2% rau erythritol.

Solubility ntawm erythritol yog 36% ntawm 25 ℃, uas yog ib nrab ntawm solubility ntawm sorbitol. Qhov kev solubility no tsis yog teeb meem hauv kev ua zaub mov, tab sis rau qee cov khoom noj uas tsis xav kom cov piam thaj qab zib crystallize, erythritol yuav tsum tau siv ua ke nrog lwm cov suab thaj lossis qab zib cawv. Nws solubility nyob rau hauv dej yog heev cuam tshuam los ntawm kub. Ntawm qhov kub ntawm 80 ℃, nws yog li 75%, zoo ib yam li sucrose, thaum nyob rau ntawm qhov kub ntawm 20 ℃, nws txo mus rau 35%. Qhov no ua rau nws muaj crystallinity zoo thiab cov yam ntxwv ntawm hmoov, ua rau nws tsim nyog los hloov sucrose hauv cov khoom noj uas xav tau sucrose crystallinity. Erythritol tuaj yeem nqus tau cov cua sov ntau thaum yaj, thiab nws cov cua sov ntawm kev sib cais hauv dej yog li peb zaug ntawm cov piam thaj thiab 1.8 npaug ntawm sorbitol. Txawm tias thaum sib xyaw nrog sucrose, nws cov cua sov ntawm kev sib cais yog qhov siab.
