Dear all researchers,
This is the first time I faced problem after spray dried the probiotic culture.
All these while the dried powder of probiotic can be dissolved completely in water, however after I changed the source of milk for probiotic cell culture, powder formed after spray drying was hardly to dissolve and apparent in lamellar liquid crystal. I have compare both type of milk ingredients and find out the recent use of milk contain soy lecithin, other than that everything same.
Is there anyone can provide me advice on it?
Thank you.
