Effects of different drying processes on the quality changes in Arapgir purple basil (Ocimum basilicum L.) leaves and drying-induced changes in bioactive and volatile compounds and essential oils.

The aim of this research is to examine the effects of drying purple basil leaves (Ocimum basilicum L.) under different drying conditions (freeze drying, sun-drying, and convective drying [CD] at 45, 50, and 55°C and microwave drying at 350, 460, and 600 W) on color properties, total phenolic and anthocyanin content, antioxidant activities, and changes in the composition of volatile compounds and essential oils (EOs). Increasing the drying temperature and microwave power led to an improvement in the preservation of the total phenolic content of the samples by an average of 16.

Storage of spinach juice agglomerates: Physical, flow, structural, and thermal properties.

The objective of this study was to investigate how the various storage temperatures affected the physical properties, flow characteristics, microstructure, and glass transition temperature of spinach juice agglomerates. For this purpose, spray-dried spinach juice powders were processed to agglomerates by using a modified fluidized bed dryer (1.6 m/s airflow rate, 60°C drying air temperature, 20 min processing time, and with different binder solutions containing agents as maltodextrin, gum Arabic, and whey powder isolate).

Spray Drying of Spinach Juice: Characterization, Chemical Composition, and Storage.

The 1st aim of this study is to determine the influence of inlet and outlet air temperatures on the physical and chemical properties of obtained powders from spinach juice (SJ) with 3.2 ± 0.2 °Brix (°Bx).
