the main purpose of the present study is to investigate the effect of air drying, freeze drying and vacuum drying methods on viscosity and gelation of lipidium perfoliatum seed gum. results showed that the viscosity values of samples varied from 0.31 to 1.26 pa.s at (shear rate = 12.23 s-1) and control sample gum exhibited the highest viscosity. apparent viscosity was decreased by all of drying...

The effect of sample preparation on measures of in vitro digestibility was studied using leaves of Calliandra calothyrsus. They were chopped fresh (FrCh), chopped and oven-dried at 658C (ChOD), chopped and freeze-dried (ChFD), oven-dried and ground (ODGr) or freeze-dried and ground (FDGr). Samples were analysed for in vitro dry matter and nitrogen digestibility with or without PEG addition to b...

TO THE EDITOR—Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridium difficile infection (CDI) [1].However, the methods of administration used most frequently— colonoscopy, nasoduodenal infusion, and enema—are inconvenient for patients and healthcare facilities. Thus, recent demonstrations that FMT can be administered via oral capsules and as a frozen pre...

Abstract—Lyophilization, also called freeze-drying, is an important dehydration technique mainly used for pharmaceuticals. Food industry also uses lyophilization when it is important to retain most of the nutritional quality, taste, shape and size of dried products and to extend their shelf life. Vacuum-Induced during freezing cycle (VI) has been used in order to control ice nucleation and, con...

BACKGROUND A pilot study was carried out in Pakistan to assess the feasibility of the use of lathed freeze-dried corneal tissue in the treatment of corneal scarring. METHOD Six eyes underwent lamellar keratoplasty and were followed up for 18 months. RESULTS Visual improvement was obtained in every eye. In one eye, the procedure was complicated by delayed epithelialization of the graft, but ...

Freeze-dried systems containing sucrose and organic acids were found to undergo rapid nonenzymatic browning, even at low relative humidities. Addition of protein reduced the rate of browning, especially at low humidities. It was determined that the browning was due to reducing sugars produced by acid-catalyzed hydrolysis of sucrose. This hydrolysis occurred even when water content was well belo...

As more and more emphasis is placed on the use of prosected specimens to support teaching and learning of gross anatomy, consideration must be given to developing new methods to preserve human cadaveric material, and in ways which will resist the wear and tear to which they are necessarily subjected. Taxidermists have developed techniques for freeze-drying whole small animals as a method of lon...

Starter cultures provide a basis in the production of fermented foods. Probiotics are the most important group of bacterial starter cultures. Commercial starter cultures were initially supplied in liquid form prior to the production of concentrated starter cultures. Progress in biotechnology later led to the application of concentrated starter cultures in frozen and freeze dried forms for direc...

The aim of this study was to determine the effect incorporation apple puree and maltodextrin agar sol on sorption properties structure dried gel. different drying methods behaviour aerated gels also observed. with addition 25% 40% concentration or without were prepared dried. foamed gel subjected freeze-drying, air-drying vacuum-drying. (adsorption isotherms, water uptake in time) investigated....
