WebCrystallization of trehalose, as trehalose dihydrate, was observed in frozen solutions. The dehydration of the crystalline trehalose dihydrate to substantially amorphous anhydrate … WebThe most commonly occurring crystalline form, trehalose dihydrate (depicted as T h), is stable at room temperature. 55 Careful dehydration of the dihydrate under defined …

A classic sugar, trehalose offers new solutions - Nature

WebTrehalose is a naturally occuring sugar (crystalline form). Trehalose and the food industry “Hayashibara began trehalose mass production following studies that showed it provides excellent... Trehalose dihydrate (purity >99%) was obtained from Fluka and used without further purification. Amorphous trehalose was prepared by freeze drying a 20wt% solution of trehalose in water at 20mbar with temperature increasing stepwise over 3 days from −40 to 25∘C using a LyoBeta 35 system (Telstar). Amorphous … See more Calorimetric measurements were carried out using a Seiko 220C DSC (Seiko, Japan) as described previously25. The Tgwas determined … See more X-ray diffraction spectra were recorded for trehalose tablets with a Philips X'Pert Pro diffractometer (Panalytical), using the copper Kα-line, at 45kV, 30mA in line-focus mode. The diffractometer was set up with the PW3050/6x … See more The PALS experiments were carried out in a sample cell either as a closed system (no water loss from the sample)25 or under vacuum.

RH‐Temperature Stability Diagram of the Dihydrate, β‐Anhydrate, …

WebResults: When an aqueous solution containing trehalose (4% w/v) and mannitol (2% w/v) was cooled to -40°C at 0.5°C/min, hexagonal ice was the only crystalline phase. However, upon warming the sample to the annealing temperature (-18°C), crystallization of mannitol hemihydrate was readily evident. WebPurpose: (i) To study the crystallization of trehalose in frozen solutions and (ii) to understand the phase transitions during the entire freeze-drying cycle. Method: Aqueous trehalose solution was cooled to -40°C in a custom-designed sample holder. WebMaterials and methods: Trehalose dihydrate was dehydrated isothermally at several temperatures below 100 degrees C and the anhydrous product was characterized by XRD, DSC and water vapor sorption. Results: XRD and DSC suggested that the dehydration product was a partially crystalline alpha-polymorphic form of anhydrous trehalose (T … trunk or treat cookie monster
