I did some digging and found the UST website and the product listing, but I cannot find the online list of ingredients. I do see a picture of the package, which appears to have a standard ingredient list on the back side, but it could not be read in the picture.
At 2400 calories per full bar, it is a one day ration. At $4.97 each, it is not the lowest cost ration bar available, and since I cannot find the actual ingredients, it is hard to make a judgment on comparative value.
I would say this is lower cost than a comparable number of MRE meal packs (say three MRE's per day) which are currently in the $8-13 range each ($24-39 per day). The MRE's may be a better eating experience, but with consequences in terms of digestion problems. If you've ever eaten MRE's for a length of time, you know what I'm talking about: constipation.
On the plus side, the UST bar is a relatively small size and one could carry several days worth in a BOB. One must include the weight of water needed to make this bar edible (eating it dry will not be pleasant, but possible).
This might be a good choice for a 72 hr. kit or part of one's permanent vehicle kit. I do not know how well these bars would keep in a vehicle, subject to wide temperature swings.
I would only consider this bar for bulk stores if I were bugging-in and had the space to store many days worth. For an emergency pack, it makes more sense.
I would like to (but cannot) compare this to the bucket food packages being sold by many prepper food resellers. I must have the ingredient list to do a valid comparison.
If anyone finds the ingredient list, please post a link (URL).
