Effects of freezing and thawing on microbiological and physical-chemical properties of dry-aged beef
(2020-03-01)
This study evaluated the effects of freezing, prior to and after dry aging, on the microbiological and physical-chemical quality of beef. Strip loins (n = 24) from 12 carcasses were assigned to four treatments: non-frozen ...
Freeze-drying microscopy in mathematical modeling of a biomaterial freeze-drying
(UNIV SAO PAULO, CONJUNTO QUIMICASSAO PAULO, 2012)
Transplantation brings hope for many patients. A multidisciplinary approach on this field aims at creating biologically functional tissues to be used as implants and prostheses. The freeze-drying process allows the fundamental ...
The influence of freezing rates on bovine pericardium tissue Freeze-drying
(Tecpar, 2009)
The bovine pericardium has been used as biomaterial in developing bioprostheses. Freeze-drying is a drying process that could be used for heart valve's preservation. The maintenance of the characteristics of the biomaterial ...
Care during freeze-drying of bovine pericardium tissue to be used as a biomaterial: A comparative study
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Bovine pericardium (BP) tissue is widely used in the manufacture of bioprosthetics. The effects of freeze-drying on the BP tissue have been studied by some researchers in order to decrease their cytotoxicity due to ...
Moisture sorption isotherm characteristics of freeze-dried D-limonene emulsions in modified chitosan and maltodextrin
(TAYLOR & FRANCIS INC, 2008)
This article reports on modified chitosan as an alternative substance for protecting loss of volatile compounds during freeze drying. Moisture sorption isotherms of freeze-dried D-limonene emulsions in modified chitosan ...
Calcium phosphates nanoparticles: The effect of freeze-drying on particle size reduction
(2020-01-01)
Calcium phosphate bioceramics have been widely used in medical applications, such as orthopedics and odontology, due to their similarities to the synthesized material with the calcium phosphate present in the mammals. The ...
Effect of drying method on the sorption isotherms and isosteric heat of persimmon pulp powder
(Chiriotti Editori, 2010-01-01)
Moisture equilibrium data of persimmon pulp powders with 50% maltodextrin (dry basis) obtained with different drying methods were determined at 20, 30, 40 and 50 degrees C. The spray-dryer gave a dry product with a higher ...
