induced by high pressure processing (HPP) were investigated. Because pressure
treatments evaluated were greater than current industry specifications, a volunteer
panel composed of raw oyster consumers was chosen to evaluate desirability of
HPP-treated oysters in a blinded test. Using a 1-7 hedonic scale, where 7 is
like very much and 1 is
dislike very much, oysters
were evaluated organoleptically for flavor, aroma, appearance, texture and general
acceptability. The average acceptability score for untreated oysters was 4.64.
Acceptability scores were 5.14, 5.13 and 5.28 at 300, 400 and 500 MPa for room
temperature (22°C) pressure treated oysters, respectively. For oysters treated
at 6°C, acceptability scores were 5.02, 5.53 and 5.38 for 400, 500 and 600
MPa treatments, respectively. Overall results indicate that HPP-treated oysters
were preferred over non-HPP-treated oysters and that it is possible to perform
HPP at ≥400 MPa which is required to inactivate shellfish-borne hepatitis
A virus and human norovirus within shellfish meat, without a loss of oyster
desirability. This study demonstrates that oysters treated by HPP under conditions
that are known to inactivate human norovirus and hepatitis A virus would be
accepted by consumers and therefore HPP can be a commercially viable intervention
for virus contamination in raw shellfish.]]>Bauer, B.A. and D. Knorr,200568329334Berlin, D.L., D.S. Herson, D.T. Hicks and D.G.
