Food Production
Revised : 27 Oct 2021
Prior to v3.07, there was one and only one edible Amount Resource conveniently called food.
Since then, we have added a variety of edible food resources. This includes all crop produce (such as sesame, wheat, soybean, rice) and their derived products (such as rice flour, wheat flour, sesame oil, soymilk, soybean oil, tofu, soy flour, etc.) as defined in resources.xml.
As of build 5191, there are 82 edible food resources in total.
Some food resources can be utilized for creating other Amount Resource or Item Resource (a.k.a. Part).
For instance, cane fiber is a processed fiber that can be produced by the crop sugarcane.
Another example is fiber cloth, which is an Item Resource made from the combination of soy fiber and cane fiber.
A Food Production Process takes some inputs of resources and gives some outputs of food resources.
No doubt, it is very similar to a Manufacturing Process in its concept of operation.
We could definitely expand how others food resources could be utilized in manufacturing and construction as some might become the bases for plastics production, shredded plant material for strengthening bricks, bamboo or wood for construction, etc..
As of build 5184, the following 7 types of food resources are considered "dessert" :
| Dessert |
|---|
| sesame milk |
| soymilk |
| sugarcane juice |
| cranberry juice |
| strawberry |
| granola bar |
| blueberry muffin |
We define a total of 18 types of main dishes, 14 side dishes (5 soups) that can be made. See meals.xml.
Currently, the effect of the main dishes, the side dishes and soups are indistinguishable.
All meals serve to provide energy and reduce hunger by mass. They only differ from the ingredients that they comprise.
At crop harvest, each food crop will be turned into its food resource.
Currently, we have the following 6 types of oils being produced from primarily food crop in the greenhouse.
| Oil Type | Origin |
|---|---|
| Sesame Oil | Oil pressed from sesame seeds |
| Rice Bran Oil | Oil extracted from the germ and inner husk of rice |
| Peanut Oil | Oil extracted from peanuts |
| Garlic Oil | Oil pressed from garlic |
| Soybean Oil | Oil derived from soybean |
| Fish Oil | Oil derived from fish |
Meals are made in kitchens by chefs.
If no oil is being produced in a settlement, the quality score of meal in a kitchen will be lower.
Note that the quality score for each batch of meals is being displayed in the Kitchen/Cafeteria tab in the Settlement Unit Window.
If settlement A has a surplus of a food resource and settlement B has a high demand for it, settlement B will attempt to start a Trading Mission with settlement A to trade that food resource.
Currently, if you want to keep track of how much a food resource in available, open the Food tab in Monitor Tool and it will show the quantity or the amount in kg for each settlement.
If you want to start or end a food production process, open the Food tab of a settlement's window and choose that food production process.
If you want to see the supply and demand of a particular food resource, open the Goods tab in Monitor Tool and it will show the Value Points (VP) of all resources.
Since v3.2.0, we have added a FISHERY building function and a Fish Farm building. Large Greenhouse also houses a small fish pool for growing fish.
In future, we may model the contribution of small animals such as shrimp, insects (mealworms, etc) as food resources.
Also, we notice the idea of algae farming has been frequently quoted in many journal papers dealing with living and thriving in a space colony.
One day, we may code how 'algae' grows and produces fuel or performs other chemical processes that benefit the colonists.
We might even include different types of fertilizer suitable for boosting the growth of different crops so as to yield more food crops during the harvest.
