there was not apparent
influence on the size of the particles. In solid UV diffuse
reflectance spectrum (Fig. 7) the same amount of the UV
blocker about 5% was incorporated in two experiments of
line A and line B, but VE added in line A about the same
amount of the UV blocker. We can observe that there was a
visible increasing ultraviolet absorption within UVB band
from wavelength 250–325 nm compared with line B and
width of peak was broadened. This tendency reflected that
retinol improved the 3,4,5-trimethoxybenzoylchitin’s UVB
absorption.
