fermentation agent; fermenting by adopting a segmented temperature change
fermentation way to prepare blueberry yoghourt to ensure that probiotics are furthest proliferated and have better cold and
heat stress resistance; then adding a protective agent with a better anti-freezing effect, and freeze-
drying to obtain functional blueberry yoghourt freeze-dried
powder with high content of viable probiotics and strong cold and
heat resistance; and finally scientifically compounding with clover extract, germinated
brown rice,
plant extract,
dextrin,
probiotic factors,
magnesium stearate and the like, and pressing by a multi-
impact rotary tablet press to obtain the probiotic blueberry press candy which has high content of viable probiotics, good stability and long
