More than 50 per cent of all German households own a freezing appliance and so far the market of frozen foods is constantly increasing (1 per cent from 2017 to 2018). Despite frozen foods playing an important role in our everyday life, little is known about the consumer’s habits at home. The purpose of this paper is to uncover gaps in the knowledge about consumer behaviour when handling frozen food. Moreover, the impact of consumers on the quality of frozen products should be assessed.

A representative online survey was carried out to investigate different aspects of consumer behaviour concerning frozen foods. Respondents (n=2,053) were questioned about their general handling habits regarding eight different food groups: fruit, vegetables, meat, fish, bread, pastries, ready-to-eat meals and leftovers. The focus was on freezing, pre-handling, packaging and thawing – depending on the age of those questioned and combined with best practice advice regarding quality storage of frozen products.

Most Germans have the opportunity to freeze food and keep their freezers full or medium loaded. Older participants act more efficiently towards quality storage, but more education about freezing and frozen storage would be generally helpful to maintain quality of frozen foods and increase utilisation of freezers, using their full preservation potential.

No open questions were asked due to the scope of more than 2,000 participants, which, in retrospect, would have been instructive.

Consumer handling of frozen food in Germany was investigated in a representative way for the first time, covering age groups from 18 to 69 and household sizes from 1 to >4 people, focussing on eight major food groups.
