The aim of this research was to study the impact of different carrier types on the characteristics of jujube extract powder fabricated by spray drying. The results showed that powders with WPI had better stability, higher retention of polyphenolic compounds, and higher encapsulation efficiency, while powders with alginate had smaller particle size.
The aim of the research was to study the impact of various carrier types (sodium alginate and blend of sodium alginate with WPI) on the physicochemical, structural, and thermal characteristics of Jujube extract powder fabricated by spray drying. TPC and antioxidant activity, solubility, moisture, EE, powder yield, DSC, particle size, and morphology of powders were surveyed. The use of WPI resulted in powders with less moisture (10%), lower solubility (98.04%), and better powder yield (22.50%). WPI-produced powders showed the best retention of polyphenolic compounds (2949.2 mg/L) and the highest activity of the encapsulation efficiency (70.93%), and moreover, they had a higher Tg (68.50 degrees C), indicating powders that were more stable during storage. All samples showed a large number of spherical particles along with a number of indented particles, and these indentations were more common in protein capsules. In terms of particle diameter, the particles produced with alginate were smaller (6.51 mu m). It can be stated that the particles containing proteins can have more effective and efficient outcomes. Novelty impact statement Both sodium alginate and sodium alginate/WPI powders were loaded with jujube extract (JE) by spray dryer. The encapsulation efficiency of jujube extract in sodium alginate/WPI powders was more. Incorporation of WPI to sodium alginate increased yield, moisture, solubility, and TPC and preserved jujube extract effectively.
