Finalist Evaluation

Judges'' comments


Thank you for your submission to Climate CoLab. The Judges would have liked to see more examples and evidence to support this proposal, and/or evidence of pilots/tests of this idea. They also had some concerns about the technological feasibility of the proposal.

Judges'' comments


Thank you for your proposal. However, there are still some rucial information missing to make the proposal a solid candidate for the finalist stage. Please address the questions below in your next round of iteration:

1. How does it work?
2. Why does the protein coating not get eaten by hungry bacteria? how does the protein coating dehydrate?
3. What is the cost of the protein coating?
4. We need more references on PS and clearer explanation of how it works.
5. Dehydration degrades nutrients- how are you planning on addressing this?

Best of luck!

Many thanks for your thoughtful suggestions.

To answer your questions:

1. PS Coating works by creating a virtually undetectable and safe (GRAS, FDA Approved) barrier that rejects microbial attack and prevents oxidization, while allowing moisture to escape. We coat food products that will be dehydrated, then spread them out on racks inside a covered room with large fans at either end to facilitate significant airflow. Within 8 to 16 hours the product is fully dehydrated (depending on the starting moisture content of the material being dehydrated).

2. Bacteria need moisture to flourish. The surface of the coating is bone dry and the coating dehydrates to a glass hard surface which means there is no cozy environment for bacteria to live in. 

3. My company identified, and acquired the worldwide exclusive license to PS coating, the cost is between $ 12.50 per Kg   Usage is 0.5-1.0%  . For a mix of 0.5% the cost per ton at $ 16.00 per Kg is $ 80.00 per ton or 8 cents per Kg converted to lbs this equals 3.6 cents per lbs.

4. exactly how it works is a proprietary property. However you can comfortable say that the coating when it is dry constitutes a one-way membrane that allow moisture to escape one way (internal to out) but limits external moisture from entering (external and in). Furthermore it prevents oxygen from contacting the product.

5. Most of the degradation during dehydration processes comes from either heat or UV-light exposure. Since our PS coating system is based on low-no heat, and takes place in a UV protected dark room, there is little to no degradation.

In other words it is NOT true that dehydration in itself degrades the product, it is more the source of dehydration that degrades the product: (typically heat/freezing/UV light etc).  

In a nutshell: Vitamins A and C are decreased if they come in contact with air (oxygen) or heat. This does not apply to our PS coating process. Vitamin A is very light sensitive and so is Beta-Carotene, the different enzymes in food products should be safe with temperatures under 115 degrees.

(I am currently on my honeymoon and the computer in the lobby where we are staying only allows 20 minute sessions, so it booted me off before completing my comments before, below I have revised #3 for clarity.)

3. Cornucopia Group has identified, and acquired the worldwide exclusive license to PS coating, the cost to coat food products is between $12.50 and $18 per Kg   Usage is 0.5-1.0%  . For a mix of 0.5% the cost per ton at $16.00 per Kg is $80.00 per ton or 8 cents per Kg converted to lbs this equals 3.6 cents per lbs of food dehydrated.

Thank you once again, please let me know if you would like any further explanations or details!

Cheers,

Chad

Also, I have added the info suggested into the proposal, in the what actions do you propose section (since its the only area where I had space to add anything due to character restrictions.)
