Amylase is one of the most important enzymes in the world due to its wide application in various industries and biotechnological processes. In this study, amylase enzyme from Hylocereus polyrhizus was encapsulated for the first time in an Arabic gum-chitosan matrix using freeze drying. The encapsulated amylase retained complete biocatalytic activity and exhibited a shift in the optimum temperat...

Probiotics are microorganisms that when ingested in high enough numbers beneficially affect the host’s health. To reach these beneficial results, it is necessary to maintain good viability of the probiotic strains during processing, storage and consumption. Stress conditions that usually affect viability of probiotics during production are the following: large concentration of fermentation by-p...

The amount of shrinkage and the scanning electron microscope appearance of specimens of rat tongue, soft palate and small intestine, dehydrated by air­ drying, the critical point technique, the camphene technique and freeze drying were compared. In the specimens of tongue the area shrinkage ranged be­ tween 11,8 and 30,4 per cent, in the soft palate from 19,8 to 37,4 per cent and in the small i...

Nanospheres of poly(methacrylic acid-grafted-poly(ethylene glycol)) were prepared by solution/precipitation polymerization. As colloidal drug delivery carriers, they present unique properties that render them promising candidates for oral protein delivery. The polymerization was carried out in water and the resulting suspension was freeze-dried. As with many colloidal systems, the freeze-dried ...

Fruit mixed pulp has the objective of improving nutritional and sensorial characteristics, as well development new flavours aromas. Different methods drying (e.g., spray-drying, spouted bed drying, freeze-drying) can influence quality final product. The this study was to select method that enables production acerola-ceriguela (ACMP) with higher quality. For selection, powder pulps were evaluate...

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...
