I am currently working on a solid DIY version of Soylent specifically designed for camping trips. It should have the following properties:
- High caloric density so it’s lightweight
- Modular shape so it can fit anywhere and does not require specific packaging
- Not lacking important micronutrients but not necessairly 100% complete (since camping trips are of short to medium duration)
- High in Sodium, Potassium and Magnesium to compensate the loss of electrolyte due to perspiration.
- Have enough protein to cover at least the daily needs in essential amino acids
- Have a taste as neutral as possible
- Have extremly low water content for long time unrefrigerated conservation
- Should not require cooking or washing dishes
What I’ve came up with is a paste (texture like Play-Doh) based on almond, cashew and sunflower butter. I add maltodextrin sirup, complete milk protein, waxy maize, chia seeds, salt and potassium. It’s about 63% fat, 23% carbohydrate and 14% protein.
I have made a few tests but I struggle to find sunflower butter in Europe so I have to make it myself. I have been using Potassium citrate as Potassium supplement but the taste is very salty and it upsets my stomach. I’m waiting for a delivery of Potassium Gluconate and Potassium Aspartate for tests.
The taste is nice (except that it’s a bit too salty at the moment). It’s not neutral but it’s not identifiable (you can’t taste the almond nor the cashew). So I assume that it would be possible to eat large quantities of it without getting bored (which is the inconvenient of peanut butter on tortilla bread, the classic long hike stapple food).
