FRoSTA specializes in frozen fish, vegetables, fruits, herbs and ready-to-eat meals in three segments: brand business, private label and foodservice.

Its brands include FRoSTA, Elbtal, La Valle Degli Orti, Mare Fresco, Surgela, and tiko.

The private label business operates under the FRoSTA and COPACK names, with sales channels to European food retailers such as Aldi, Lidl, and Norma.

However, the company was instead brought to the brink of ruin due to cost increases and a market unprepared for early adoption of the concept at double the price.
