Effects of drying methods and acidic strength on physicochemical properties of potassium caseinate

Abstract

The aims of the present study were to characterize physicochemical characteristics and chemical structures by Fourier Transform Infrared (FTIR), and mark dissolved protein content, microstructure, and moisture content of potassium caseinate prepared by drying methods and acid strength. The experiment was arranged according to factorial complete randomized design with triplicates, while data from FTIR and microstructure analysis was presented descriptively. The results demonstrated that acids and drying methods for preparing potassium caseinate could increase antioxidant activity, a* score (reddish) and b* score (yellowish). Specifically, freeze-drying method coupled with acid treatments accounted for reducing moisture content but improved viscosity and microstructural properties. Briefly, we could argue that drying techniques and acids established noticeable effects on the quality of potassium caseinate.

Medicinal Plant Drying Using a Superabsorbent Polymer Dryer Incorporated with an Insulated Heater

“…Using an oven-drying method, a short drying time and a more controlled operational temperature can be attained [8]. Nevertheless, this technique is less favorable in Simplicia drying due to its tendency to induce color changes and significantly reduce the quality of the materials [9]. Microwave-assisted drying can preserve bioactive substances in the medicinal plant materials with adequate dehydration efficiency.…”
