I am Dr. Cathy Liu, Seafood Technology Specialist at University of Maryland Extension (UME). I am currently working with Jackie Takacs (UME), Barry Nash (North Carolina State University), and Dr. Evelyn Watts (Louisiana State University) to study fresh crabmeat taste properties. This research is approved by the University of Maryland College Park’s Institutional Review Board under protocol number IRBNet Package#: 1933295-2We would like to invite you to participate in our taste study.

The purpose of this sensory evaluation survey is to understand consumers’ acceptance of precooked, ready-to-eat, Atlantic blue crabmeat treated by high-pressure processing (HPP) technology and to estimate its market potential. For more information on high-pressure processing, click here.

How is the HPP crabmeat produced? Live blue crabs are steamed under pressure at temperatures between 240-250°F for 5-8 minutes. Then the meat is picked by hand, packed in plastic containers, and sealed with film. The sealed containers are then subjected to HHP treatment to extend the crabmeat's shelf life. 

We are seeking participants who:

  • Are at least 18 years old
  • Enjoy eating crabmeat;
  • Do not have any allergies to crab, anchovies, eggs or wheat gluten
  • Are not pregnant, nursing or immunocompromised

The taste tests are expected to begin on June 1, 2023 and last for 3 weeks, one sampling per week. You are expected to taste the crabmeat right out of the container and evaluate its flavor, texture, aroma and appearance. If you decide the crabmeat is acceptable, we ask that you then use the crabmeat as a prime ingredient to make crab cakes using our suggested recipe and tell us how it performed in comparison to the fresh crabmeat you have used before.

Project Title

Seafood Safety and Quality Programs: Crabmeat Sensory Evaluation Surveys

Please refer to IRBNet Package Number 1933295-2 when contacting us with any questions or concerns.

Purpose of Study

The research focus of this Crabmeat Sensory Evaluation Survey is being conducted by Dr. Cathy Liu and Jackie Takacs at University of Maryland Extension, along with Barry Nash at NC State University/NS Sea Grant, and Evelyn Watts at Louisiana State University/Louisiana Sea Grant. We are inviting you to participate in this research project because you are a seafood consumer, buyer, or restaurant chef who serves seafood to the general public. The purpose of this research project is to evaluate the flavor, texture, aroma and appearance of crabmeat that has been processed to deliver a refrigerated shelf life of up to three weeks without compromising its superior sensory quality. 

Procedures

You will receive one pound of HPP crabmeat per week for the three-week sensory evaluation. The crabmeat is a precooked, HPP treated, and ready-to-eat product that needs to be stored in a refrigerated condition (between 32°F and 40°F). IT SHOULD NOT BE FROZEN AT ANY POINT DURING THIS STUDY. Testing should be started within 2 days upon receiving the crabmeat.

The procedure involves tasting the crabmeat and numerically rating it in an anonymous survey according to a 7-point scale where 1 = Completely Unacceptable and 7 = Excellent. You are expected to taste the crabmeat right out of the cup and evaluate its flavor, texture, aroma and appearance.  We also ask that you provide comments about what you liked and disliked about the product and why. If you decide the crabmeat is acceptable, we ask that you then use the crabmeat as a prime ingredient to make crab cakes using our suggested recipe and tell us how it performed in comparison to the fresh crabmeat you routinely use. Each evaluation should take approximately 60 to 90 minutes including crabcake preparation and cooking.

Completed evaluations can be returned by email or by mailing the survey using the stamped return envelope.

Potential Risks and Discomforts

The products we plan to use are commercially safe products purchased from licensed crabmeat processing plants, regularly inspected by the state and the U.S. Food & Drug Administration. Therefore, there are minimal known risks to the study participants since we will exclude individuals who are allergic to seafood (crab, anchovies), egg or wheat gluten and/or who are pregnant, nursing, or immunocompromised.

Potential Benefits

There are no direct benefits from participating in this research. However, possible benefits to participants may include gaining access to fresh, unpasteurized (i.e., canned) crabmeat that retains its sensory quality for longer than five to seven days. Reduced perishability means higher revenues for crabmeat processors and their restaurant customers.  We hope that, in the future, other people might benefit from this study through improved understanding of HPP technology and its application to enhance seafood safety and quality.

Confidentiality

Any potential loss of confidentiality will be minimized by submitting your sensory evaluations anonymously, by mail or electronic survey. The results will be maintained on secure computer systems at University of Maryland Extension and NC State University that are password-protected and accessed only by the PIs. Non-electronic data will be stored in locked offices with locked cabinets.  

If we write a report or article about this research project, your identity will be protected to the maximum extent possible.  Your information may be shared with representatives of the University of Maryland, College Park or governmental authorities if you or someone else is in danger or if we are required to do so by law.

Participants' identifiable information collected during registration will be deleted within two years (24 months) after the completion of the project.

Medical Treatment

The University of Maryland or North Carolina State University will not provide any medical, hospitalization or other insurance for participants in this research study, nor will the University of Maryland and North Carolina State University provide any medical treatment or compensation for any injury sustained as a result of participation in this research study, except as required by law.

Right to Withdraw, Questions and Contact Info
