Packaging, beer

France. In Prance, beer production is concentrated in the northern and eastern parts of the country. Beer production decreased from 22.3 X 10 hL in 1975 to 19.9 x 10 hL in 1988 packaged beer amounts to about 80% of the total. Per capita consumption was about 48 L in 1987. 

In this work, we adapted a method for the analysis of beer aldehydes using solid-phase microextraction (SPMF) with on-fiber derivatization. This extraction technique does not require solvents, consists of a one-step sample preparation procedure, and provides high sensitivity and reproducibility. It enabled a detailed study of aldehyde level changes during packaged beer storage. 

Tin and steel cans became widely accepted during World War II. This rising demand also led to rising costs of tin plate, causing can producers to look for an economical replacement. Aluminum filled this need and, in 1959, the Adolph Coors Company became the first American brewer to package beer in an aluminum can.21... 

Plastic bottles for carbonated beverages are mostly made of PET as it offers high tensile strength and good barrier properties. Blow-molded PET bottles account for 33% of the total carbonated soft drink market. For packaging beer, which is oxygen sensitive, PET bottles are coated with PVDC, while the base cups that support the bottle are usually made of HDPE. 

Other packaging aids (e.g. labels, glue, shrink films, carton boxes, trays, crates) are not be considered microbial hazards. Nevertheless, a certain standard of hygiene is necessary to deliver an appropriate product appearance to the consumer. Beer in packaging that has a dirty or even miaobially spoiled look will not be accepted, although the packaged beer may be of best quality.
