Abstract:

The article presents an analysis of the results of experimental research on the structuring of fruit puree with different content of insoluble dry substances. The structuring was carried out in the process of dehydration of the puree to different values of the water activity, ranging from 0.38-0.78. The correlations between the water activity (aw) and the humidity of the studied products of different quality were established and also between the aw value and the content of insoluble dry substances. The correlations between the values of the organoleptic assessment of the quality of structured

The Case of Eutectic Solvents The article presents a case study in which a simple, practical observation significantly changed the perception of basic phenomena regarding the mechanism of cell functioning, and thus was able to change the existing theory. This observation drew attention to the fact that the extract obtained from the dry plant substance with the use of pure alcohol, after distilling off the solvent, does not give a dry concentrated extract, and the viscous residue cannot be dried by disti

Introduction. N. N. Blokhin National Medical Research Center of Oncology of the Ministry of Health of Russia synthesized an original derivative of indolocarbazole with the carbohydrate residue xylose, which has a pronounced cytotoxic and anti-angiogenic activity. The substance LCS-1269 is an amorphous powder that is almost insoluble in water, which causes difficulties in the development of an injectable dosage form (IDP). To solve this problem, a technological approach to obtain a solid dispersion (SD) of LCS-1269 has been proposed.Aim. To develop a model of IDP of the indolocarbazole derivati

Abstract:

The production of orodispersible films (ODFs) with suspended insoluble drug substances is still a challenge, mainly due to the difficulty associated with achieving a proper homogeneity and mechanical properties of the films. Hypromellose (HPMC) and a mixture of polyvinyl alcohol (AP) and povidone (PVP) were compared in terms of their suitability for ODFs incorporating suspended micronized loratadine (LO) in a concentration range of 10%–40%. In a planetary mixer (Thinky), a uniform dispersion of LO in an aqueous viscous casting solution was obtained. The suspended LO particles caused dose-depen

Abstract:

Aloe vera products, both in food and cosmetics, are becoming increasingly popular due to their claimed beneficial effects, which are mainly attributed to the active compound acemannan. Usually, these end products are based on powdered starting materials. High temperatures during the drying process to obtain the starting materials have several advantages, like shortening the drying time, eliminating toxic aloin and reducing bacterial contamination. Nevertheless, there are two major drawbacks: first, at temperatures of 80 °C or higher, structural changes in acemannan, especially its deacetylatio

Six sweetpotato cultivars were evaluated for changes in individual sugar concentration, dry weight, and alcohol insoluble solids (AIS) during growth and development. Measurements were taken at weekly intervals from 7 to 21 weeks after transplanting. Sucrose, the major sugar during all stages of development, generally increased in concentration throughout development for `Heart-o-gold', `Travis', and `Jewel', but peaked at 17 weeks for `Beauregard' and `Whitestar'. The high-dry matter white flesh cultivars of `Rojo Blanco' and `Whitestar' contained the lowest sucrose concentration. The monosacc

Electrospinning is a new technology whose scope is gradually being developed. For this reason, the number of known polymer–solvent combinations for electrospinning is still very low despite the enormous variety of substances that are potentially available. In particular, electrospinning from low-toxic solvents, such as the use of dimethyl sulfoxide (DMSO) in medical technology, is rare in the relevant scientific literature. Therefore, we present in this work a series of new polymers that are applicable for electrospinning from DMSO. From a wide range of synthetic polymers tested, poly(vinyl al

They become available only after indirect action - humus mineralization, when it transforms into simple mineral compounds. In nature, more humic acids are found in low-calorie fuels - brown coal, peat and others. For power engineering, humic acids are an undesirable component, fuel with their high content is of low grade. However, for the production of humates - the more of them in the r

The accuracy of the calibration of all investigated parameters decreased during storage.
