“We would get anyone who’s extracted a compound from fruit that’s efficient for residual oxidative stress, nevertheless it must be stabilized,” he stated. “It’s not secure in a liquid section and it’s not secure very lengthy in a frozen section. Freeze drying is approached and we’ve performed plenty of supplies to pay attention it, as a result of now that you simply take away the water, you now have the efficiency in a dry, smaller quantity format.
