3.4. Sensory properties of fermented soy milk beverages
In this study, the apple juice was added to soy milk at different
concentrations to improve the acceptability of fermented soymilk
drink. Researches have shown that fruit juices could be used for the
production of fermented soy milk beverages with a wide range of
concentrations from 1 to 50 % to improve sensory properties
(Beasley et al., 2003; Daneshi, Ehsani, Razavi, & Labbafi, 2013;
Dauda & Adegoke, 2014). In the present study, apple juice concentrations
of lower than 15% was not suitable for sensory appeal,on the other hand increasing the concentration to lead to syneresis
during the fermentation period (data not shown).
