there are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. however, there is little information to prove such effect on flat breads. the main aim of this study was to improve the quality of barbari dough and bread (iranian flat bread) in terms of texture, taste and general acceptability of fres...

The microcrystalline cellulose is an important ingredient in pharmaceutical, food, cosmetic and other industries. In this study, the microcrystalline cellulose, obtained from the stalk of Sorghum caudatum was evaluated for its physical and tableting characteristics with a view to assessing its usefulness in pharmaceutical tableting. The microcrystalline cellulose, obtained from the stalk of Sor...

This study was aimed at evaluating chitosan-microcrystalline cellulose blends as direct compression excipients. Crab shell chitosan, α-lactose monohydrate, and microcrystalline cellulose powders were characterized. Blends of the microcrystalline cellulose and chitosan in ratios 9 : 1, 4 : 1, 2 : 1, and 1 : 1 as direct compression excipients were made to constitute 60% of metronidazole tablets. ...

This study aimed to enhance the degrading ability of microcrystalline cellulose in the mycelia of the mushroom Lentinula edodes. The mycelia were incubated in an autopolyploidization medium containing colchicine for more than 1 week at low temperature. After incubation, many larger nuclei (autopolyploid nuclei) were observed in the mycelia.Mycelial mats were then incubated on agar medium contai...

Gaseous acetylation of microcrystalline cellulose (MCC) was carried out to modify its chemical and physical properties and at the same time to preserve the morphology of cellulose microfibrils. Spectroscopic analysis of the samples was indicative of the success of the reaction as indicated by FT-IR and H-nmr studies. The chemically modified microcrystalline cellulose (MCC) were blended with hig...

A new cellulosomal protein from Clostridium cellulolyticum Cel9M was characterized. The protein contains a catalytic domain belonging to family 9 and a dockerin domain. Cel9M is active on carboxymethyl cellulose, and the hydrolysis of this substrate is accompanied by a decrease in viscosity. Cel9M has a slight, albeit significant, activity on both Avicel and bacterial microcrystalline cellulose...

Primary and secondary amines react with ethynylcobalticinium under mild conditions in the absence of a catalyst and an additional solvent to give quantitative yields of dark-red microcrystalline cobalticinium trans-enamines that show a remarkable push-pull electronic structure.

Bone repair or regeneration is a common and complicated clinical problem in orthopedic surgery. The importance of natural polymers, such as microcrystalline chitosan, and minerals such as HAp and β-TCP, has grown significantly over the last two decades due to their renewable and biodegradable source, increasing the knowledge and functionality of composites in technological and biomedical applic...

This study demonstrates the capabilities of NIR imaging as an effective tool for characterization of pharmaceutical powder blends. The powder system used in this small-scale powder blending study consists of acetaminophen (APAP, the model API), microcrystalline cellulose (MCC) and lactose monohydrate. Mixtures of these components were blended for different times for a total of ten time points (...
