Off-Flavors

2017
Webster’s Third New International Dictionary defines an off-flavor as “a flavor that is not natural or up to standard owing to deterioration or contamination.” Compounds causing off-flavors can be formed from food constituents or they can migrate into the food by contamination.

Off-Flavors and Harmful Algae

1998
Phytoplankton are an essential part of the microbial community of most aquaculture ponds and the role of algae in oxygen budgets and nutrient cycling has been stressed throughout this book. Quite frequently, however, phytoplankton becomes a nuisance in pond aquaculture.

Off-Flavors in Aquaculture

2003
Off-Flavors in Aquaculture discusses types of off-flavors, analytical detection methods for off-flavor compounds, and pre-harvest and post-harvest management practices for preventing and dealing with off-flavor in aquaculture products such as catfish, shellfish, shrimp, tilapia, and trout.

Off-Flavor Problems in Aquaculture

Reviews in Fisheries Science, 2000
Foods produced in aquaculture are often more expensive than other sources of animal protein. To capture and maintain market share, they must therefore be of consistent, superior quality. This article reviews off-flavor problems in aquaculture that can adversely affect market demand, with emphasis on off-flavors acquired prior to harvest of the cultured

Off-flavor production in frozen strawberries

Postharvest Biology and Technology, 1996
Abstract The development of off-flavor in frozen-thawed strawberries was attributed to the production of H2S. The identity of H2S was verified both chemically, through its reaction with lead acetate, and using gas chromatography-mass spectroscopy analyses. The duration of the production of H2S was longer in berries stored at −40 °C and −80 °C than in

Enzymatic Removal of Off-flavors from Apple Juice

Journal of Agricultural and Food Chemistry, 2008
Contaminating microorganisms such as Actinomycetes, Alicyclobacillus, and Chlostridium can generate off-flavors in apple juices. Such bacterial metabolites represent, besides phenol types such as guaiacol and 2,6-dibromophenol, a broad range of other chemicals, for example, geosmin, 2-methylisoborneol, or alpha-terpineol.

Identification of Off-Flavor Compounds in Beer

Journal of the American Society of Brewing Chemists, 2000
Off-flavors in beer and brewing materials were identified. When the concentration of the flavor component was high, abnormal peaks were detected on the gas chromatogram. When an off-flavor was detected by tasting, the putative component was analyzed by gas chromatography mass spectrometry (GC-MS).

Off Flavors in Fish and Shellfish

1992
SUMMARY Off flavors in fish and shellfish are due to many intrinsic and extrinsic factors. These include chemical and biochemical composition of the fish or shellfish, physiological state and diet of the animal, environmental conditions, post-mortem biochemical and microbiological activity, processing techniques employed, and storage conditions. Many

Off-flavors in foods and aquaculture

2012
Development of off-flavors is a common phenomenon in different food materials and water resources. Off-flavors not only render the foods and water unfit for human consumption but also badly impact the commercial markets concerning these commodities. In the previous decade, a tremendous amount of research has been carried out on the issues related to ...

Alcoholic Off-Flavor Disorders in Fresh Fruits

2023
The off-flavor disorder is one of the most quality deteriorating and undesirable postharvest physiological disorders in fresh fruits. Over-biosynthesis and accumulation of ethanol metabolism-related metabolites such as acetaldehyde and ethanol have been associated with an alcoholic off-flavor disorder in various fresh fruits at both pre- and ...
