“…Lee et al [34] reported that light induced the decomposition of yellow turmeric pigment. A similar observation of light-induced decomposition of curcumin was also reported by Komonsingh et al [35]. The above authors have also stated that both direct and indirect solar radiation can decompose the curcumin pigment.…”

The present work is proposed to study the effect of microwave boiling on the curcumin content of turmeric. Fresh rhizomes are subjected to different boiling methods i.e., pressure cooking, water boiling, and microwave boiling. Dried turmeric powder is used for the extraction of curcumin with the use of different solvents. Among the solvents used, ethanol to water ratio (70:30) has the highest extraction yields. Further, the curcumin extraction yields were studied using ultrasound technology at different time intervals. Ultrasound-assisted extraction (UAE) for 25 min treatment at 250 W was observed to have the highest yield. The rhizomes that are pressure cooked and tray dried at 90 °C followed by the ultrasound-assisted extraction have resulted in maximum curcumin content. The experimental curcumin value is compared with the calculated value obtained from Peleg’s model. Ultrasound can be used as a green technology to have enhanced extraction yields of bioactive compounds.

Turmeric, the rhizomes of Curcuma longa L., is one of the top selling spices, food preservatives, and food colorants. In addition, it exhibits health promoting benefits owing to its unique phytochemical composition. Nevertheless, it is commonly subjected to heat drying, hence, the dried powder is the most used form and can easily be adulterated with allied species. Therefore, our research aimed to profile the phytochemical composition and investigate the impact of drying of turmeric. Extraction and fractionation followed by LC- and GC–MS analysis resulted in the identification of a total of 161 metabolites belonged to various phytochemical classes. Moreover, multivariate data analysis identified curcuminoids, terpecurcumins, and organic acids as potential markers for drying. Based on the applied analytical techniques in combination with chemometrics, these investigations have succeeded to provide good coverage of the metabolome of turmeric in both fresh and dried forms.

“…Thin-layer drying (TLD) is a process in which materials are uniformly distributed within a dryer to generate a thin-layer structure (Akpinar, 2006;Erbay & Icier, 2010). The pace of drying is affected by factors such as the thickness and size of TLD materials (Komonsing, Reyer, Khuwijitjaru, Mahayothee, & Müller, 2022). The cost-effective drying process must be designed using operational mathematical models that optimize various drying parameters.…”

In this study, Oscillatoria sp. BTA-170 was grown in a photobioreactor for 15 days, yielding 3.1 g/L of biomass. During the composition analysis of biomass, the moisture, protein, carbohydrate, lipid, and ash contents were found to be 83.27, 6.36, 5.48, 3.79, and 1.1% on a wet basis (w.b), respectively. The tray drying properties of cyanobacterial biomass were investigated at temperatures of 40, 60, and 80 C with constant air velocity of 0.6 m/s. To reduce the moisture content of biomass from 83.27% to <10%, drying time required 2, 12, and 30 hr at 80, 60, and 40 C, respectively. The calculated effective moisture diffusivity of biomass was 5.10 Â 10 À9 , 6.34 Â 10 À8 , and 2.30 Â 10 À7 m 2 /s at 40, 60, and 80 C, respectively, and the activation energy was found to be 28.01, 31.04, and 33.27 kJ/mol at 40, 60, and 80 C, respectively. The logarithmic and Henderson and Pabis models showed the highest R 2 values of 0.997 and 0.996 at 80 C, respectively, and were thus employed to explain biomass drying characteristics. The drying constant value grew with increasing temperature, with the highest value obtained using the logarithmic model at 80 C being 0.523 (hr À1 ). The bulk density of biomass powder dried at 80 C was 598.21 kg/m 3 and the tapped density was 652.80 kg/m 3 , with Hausner ratio and Carr index of 1.091 and 8.363, respectively, showing that biomass powder had excellent flow qualities. The dried cyanobacterial biomass is a great source of protein, according to FTIR measurements. Similarly, after selecting four models based on the sorption isotherm, the GAB model was shown to be the best fit to represent the sorption behavior of Oscillatoria sp. BTA-170 powder. Practical ApplicationsThe drying characteristics of Oscillatoria sp. BTA-170 biomass were evaluated using thin-layer drying models. The primary goal of drying biomass is to remove water from the solids to a point where microorganisms and degradation chemical processes are considerably reduced. The analysis of drying properties aids in the development of a cost-effective dryer. By hastening the manufacture of biomass powder, the effective design of the drying process helps to decrease time and processing costs. After the drying process, an FTIR analysis can be used to determine the presence of
