2.4.5. Storage conditions
Dried samples were stored during 180 days in hermetically
sealed glass containers, under the following conditions:
A) room temperature, in the presence of daylight;water activity
(aw) ¼ 0.03
B) 4 C, in the presence of daylight; aw ¼ 0.03
C) room temperature, in the absence of daylight; aw ¼ 0.03
D) room temperature, in the presence of daylight; aw ¼ 0.11
Water activity (aw)was controlled by equilibrium with saturated
aqueous solution of LiCl (Sigma) and dry silica gel (Pronalab) to give
aw values of 0.11 and 0.03, respectively (Teixeira et al., 1995).
