The recipe can be doubled, tripled, etc. in the same batches to meet any media quantity requirements. Sealed in single-use foil pouches, Nutri-Fly® GF is not only convenient but also robust, and guaranteed to make fresh and substantive food throughout its shelf-life of one year from delivery. Strict lot traceability procedures are employed to each ingredient, in every batch.
