The same standards and specifications developed by the dairy industry began to
be adapted by the food industry as well. Processed food products such as fruits,
vegetables, sauces, gravies, pudding, dressings, and candy often required the same
sanitary conditions to prevent bacterial contamination and product spoilage. In the
last few years, soft drink bottlers have also become more concerned with product
spoilage, particularly with the high juice content found in many fruit juice-based
soft drinks. Although baked goods and cereals do not require the same rigid
requirements as some food products, these industries also specify sanitary flowmeters
on such ingredients as color additives, flavoring ingredients, liquid eggs,
liquid vitamin slurries, edible oils, and liquid sugars.

Probably the most stringent sanitary requirements can be found in the pharmaceutical
and biotechnology fields. Bacteria-free environments and the prevention
of product contamination are essential in the production of such products as oral
and injectable drugs, purified buffer solutions, water for injection, and in the separation
of blood serums. Highly purified products must not only be free of bacteria
but must remain free of all foreign contaminants to ensure proper processing. In
the biotech area, sanitary flowmeters are used to add nutrients such as aqua-ammonia
solutions, glucose sugars, and buffer solutions to highly sensitive bioreactors
for the cultivation of cells.
