Spray-dried rosemary extracts: Physicochemical and antioxidant properties

Physicochemical and antioxidant studies on oven-dried, freeze-dried and spray-dried agaro-oligosaccharide powders

In this work, oven-dried, freeze-dried and spray-dried agaro-oligosaccharide powders were characterized to investigate their physicochemical and antioxidant properties. Agarooligosaccharide powders were shown to exhibit high water solubility index (88.73 – 95.88%), water absorption capacity (0.96 – 2.57 g/g) and oil absorption capacity (0.40 – 0.45 g/g). Agarooligosaccharide powders were shown ...

Antioxidant activity and physical-chemical properties of spray and spouted bed dried extracts of Bauhinia forficata

Two distinct drying methods (spouted bed and spray drying) were used for production of dried extracts of Bauhinia forficata Link (Leguminosae, Caesalpinoideae). High-quality powder products in terms of physical and chemical properties were obtained. HPLC fingerprints revealed that the chromatographic profiles of flavonoid compounds present in the dried extract did not change significantly, due ...

Effect of spray dried whole egg powder on physicochemical and sensory properties of cake

As egg is a primary source of high quality proteins and offers a balanced distribution of basic food constituents such as minerals (iron, calcium, phosphorus and potassium) and vitamins, particularly vitamin E, A, B12, B2 and folic acid alongside high amounts of lipids, such as triacylglycerols, phospholipids and cholesterol to the body. Eggs were spray dried, that ultimately increase the shelf...

Supercritical fractionation of rosemary extracts to improve antioxidant activity

Spray Drying of Rhodomyrtus tomentosa (Ait.) Hassk. Flavonoids Extract: Optimization and Physicochemical, Morphological, and Antioxidant Properties

The optimal condition of spray drying purified flavonoids extract from R. tomentosa berries was studied by response surface methodology. The optimized condition for microencapsulation was of maltodextrin to gum Arabic ratio 1 : 1.3, total solid content 27.4%, glycerol monostearate content 0.25%, and core to coating material ratio 3 : 7, resulting in EE 91.75%. Prepared at the optimized conditio...
