Storing juice for a short time can be done by using a pump n seal system.This pumps the air out and slows down the breaking down of the juice.You can get them online for about 20 dollars,I use mine everyday and love how easy it is to use.Algae has the highest protein to calorie ratio known to mankind and it has a lot of phytonutrients as well.Most protein powders are worthless made from cheap materials and mixed with synthetic vitamins.Good luck on your fittness challenge.
