Ice Crystals On Frozen Food Indicate. As timothy says, ice crystals on the outside of frozen food, or packaging, do not indicate anything in particular. Either you didn't store your food properly, or your food has just been in the freezer for a long time.

It has been in the freezer since, and been stored at a pretty even 0 degrees f. However, there is still little quantitative understanding of the physics governing ice crystal formation, as indicated by the recent literature reviews (petzold and aguilera, 2009, cook and hartel, 2010, kiani and sun, 2011). Many of today's refrigerators come with an ice dispenser built into the door.

In a sugar solution such as ice cream, the initial freezing point of the solution is lower than 0° c due to these dissolved sugars (freezing point depression), which is mostly a function of the sugar content of the mix.

Also, the food texture will become unappetising and mushy. Unfortunately, that signals the probability of freezer burn. When food is frozen, a bunch of water molecules within the food form ice crystals. This is caused by several factors, including dehydration from changes in temperature within your freezer, exposure to air and food being in the freezer for too long.
