Consumer test
After the instrumental analysis of the different cookies, four
types of them were selected for a consumer test (Table 5). The
cookies made from 100% rice flour were selected as the control
cookies (100-0-0), a cookie with the highest dose of protein but
without starch (80-0-20), another with the highest dose of protein
and high starch content (30-50-20) and the last cookie without
protein but with high starch content (70-30-0). The results of the
cookie sensory evaluation are shown in Table 5. Cookies with
protein had the best scores for texture and for odour, in this case,
when no starch was added. Meanwhile, cookies with starch and
without protein got the lowest appearance and texture values.
However, this cookie did not show differences in texture with the
control cookie. No significant differences in taste between the
different cookies were observed. Consumers rated cookies pre-
pared from protein with the highest overall acceptability, although
it was not significantly different from the control cookie. However,
the cookie with high starch content and no protein got the worst
overall acceptability. The higher scores of cookies with high protein
content than the scores of cookies made with starch but without
protein may be motivated by the darker colour (similar to cookies
made from wheat flour) and the lower hardness of these cookies.
