Hello, thank you for the interesting presentations. I see that one of the main concerns are that the produce not passing QC standards. This question is open to everyone. Are there initiatives in your organization to increase consumers' acceptability on 'ugly' fruits and vegetables?

This question is specifically to Bor-Sen Chiou: When phenolics are removed by the fish gelatin, antioxidant decreased as well. Antioxidants have their health benefits. In the end product of almond hull extract, how would you balance these two aspects, between retaining the phenolics and reducing the bitterness from phenolics? Or are the antioxidant properties not that important in this case?

I might not be able to attend the live Q&A, but please feel free to reply below :)

Hi,

Thanks for viewing our presentations and we hoped you enjoyed them.

Ideally, we would like to remove the least amount of phenolic compounds and still have the extract be appealing to consumers. This would require sensory tests in the future. We are also exploring other ways to separate the phenolic compounds from the sugars without binding them to fish gelatin since phenolic compounds by themselves have value. One method we are exploring is membrane filtration. Thanks.
