Assessment of Antioxidant Activity of Spray Dried Extracts of Psidium guajava Leaves by DPPH and Chemiluminescence Inhibition in Human Neutrophils

Table 5

Physical characterization of Psidium guajava spray dried extracts.

Samples	𝑋𝑝 (%)	𝑎𝑤 (—)	Water solub. (%)	𝑑𝑝^∗ (µm)
MA 80	4.34 (0.18)	0.16 (0.03)	94.4 (1.9)	13.3 (12.0)
MDEA 80	5.82 (0.36)	0.19 (0.03)	87.7 (5.7)	12.1 (12.7)
βCD 80	3.93 (0.05)	0.18 (0.03)	83.4 (1.6)	15.8 (16.4)

𝑋_𝑝: product moisture (Karl-Fischer titration); 𝑎_𝑤: water activity ^∗𝑑_𝑝: mean diameter of the particles (deviation of particle size distribution, not the mean particle size). Values are presented as the mean (standard deviation).
