Supercritical CO2 interpolymer complex encapsulation improves heat stability of probiotic bifidobacteria

Supercritical CO2 interpolymer complex encapsulation improves heat stability of probiotic bifidobacteria.

The probiotic industry faces the challenge of retention of probiotic culture viability as numbers of these cells within their products inevitably decrease over time. In order to retain probiotic viability levels above the therapeutic minimum over the duration of the product's shelf life, various methods have been employed, among which encapsulation has received much interest. In line with explo...

Particle encapsulation with polymers via in situ polymerization in supercritical CO2

Fine Dechlorane (DCR) particles with an average size of 12 Am were successfully encapsulated with poly(methyl methacrylate) (PMMA) and poly(1-vinyl-2-pyrrolidone) (PVP) polymers via in situ dispersion polymerization in supercritical carbon dioxide (scCO2). Adjusting the process parameters can control the coating thickness, surface morphology, and degree of particle agglomeration. A uniform thin...

Supercritical CO2 extraction of Codonopsis

In the present study, Radix Codonopsis was extracted by supercritical CO2 extraction. As Ointment collecting rate and the yield of stigmasterol are index, Various reaction parameters were changed to attain the optimal conditions. The appropriate process conditions are size 40 60Mesh, 30 Mpa pressure, temperature 65 °C, 120 min, entrainer Alcohol dynamic extraction (entrainer pump flow rate of 1...

Supercritical CO2 Extraction of Ethanol

Extraction of ethanol was studied from both synthetic ethanol solution and fermentation broth using supercritical CO2 in an extraction apparatus in ranges of 313 to 333 K and 80 to 160 atmospheres, for varying extraction times. The experimental system consists mainly of four parts: a CO 2 storage system, a high-pressure liquid pump, an extractor and a product collection unit. Samples were analy...
