Effect of Storage Temperature and Light on the Freeze-Dried Amino Acids from Sugar Beet and Sugar Cane Molasses
Molasses is a significant by-product of sugar beet or sugar cane refining industry. In this work, the effects of storage temperature and packaging on the contents of free amino acids (AAs) in sugar beet and sugar cane molasses after freeze drying were inquired. The effect of different variables such as, temperature (4 and 25˚C) and light (Metallized polypropylene container and Normal polypropyl...

متن کاملAdverse effect of cake collapse on the functional integrity of freeze-dried bull spermatozoa.
Under optimal freeze-drying conditions, solutions exhibit a cake-like porous structure. However, if the solution temperature is higher than the glass transition temperature of the maximally freeze-concentrated phase (Tg') during drying phase, the glassy matrix undergoes viscous flow, resulting in cake collapse. The purpose of the present study was to investigate the effect of cake collapse on t...

15 صفحه اولThe effect of freeze-dried bone allograft and partially demineralized freeze-dried bone allograft on regeneration of rabbit calvarial bone defects: A Histological and histomorphometric study
Background and Aims: Reconstruction of osseous defects is one of the ideal goals of periodontal treatments and dental implant therapy. Different biomaterials have been used for this purpose and many studies have tried to compare and introduce the best ones. The present study aimed to evaluate the effect of PDFDB (Partially Demineralized Freeze-Dried Bone Graft) and FDBA (Freeze Dried Bone Allog...
