# Lyophilised cake

A lyophilised cake is the porous solid that remains in a vial after freeze-drying. Its appearance can range from a compact white disc to a loose powder or a thin film, depending on the amount of material and drying conditions. Variation in cake appearance alone does not indicate a difference in peptide quality.
