The Flavour of Old Apple Varieties

Styria is Austrian’s apple cultivation hot spot. About 80% of the annual harvest (corresponding to about 130.000 tons) are harvested in this region. The majority of the apples – mainly new apple varieties as Golden Delicious, Gala or Idared - are cultivated in plantations. However, about 25% of the apples are grown in so-called meadow orchards. These meadow orchards represent an enormous pool for apple varieties – mainly old apple varieties (Maschanzker, Kronprinz Rudolf, Bohnapfel and many more) that have been traditionally grown there. In many cases these varieties show completely different properties than fruits from new varieties. Even though these varieties have been cultivated in this region for many decades, the flavour properties are not described. For most varieties, a molecular characterisation of the flavour compounds is lacking.

Characterisation of Functional Barriers for Food Contact Materials

Food contact materials are materials or articles that are considered to come into contact with food. They should not release substances into food that change the properties of the food or pose a potential risk for human health. Examples for FCMs include machinery to process food, kitchenware, tableware and packaging materials, (e.g. paper, board, and plastics) 1.  The packaging should on the one hand protect the packed good from unwanted changes by e.g. air, light or oxygen and stop migration of unwanted substances from the environment or from the packaging itself (e.g. non-intentionally added substances (NIAS), mineral oil hydrocarbons…). On the other hand it should preserve the quality and taste of the food. Read more...

FFG: BeevKomp – Assessment of Compost Dairy Bedded-Back Barns with Regard of Compost Quality, Odour and Greenhouse Gas Emissions

The compost bedded pack barn is an animal-friendly housing system for cattle. It consists of a large, open resting area, usually bedded with sawdust. The most critical success factor for managing a compost bedded pack barn (CDB) is providing a comfortable, dry resting surface for cows at all times.
